Industrial Engineering Laundry – Ergonomics For Quicker And Easier Laundry


Lead Engineer- Michael Kirk:

I expect this article to change your life.  Enjoy-

 

There are two sections, theoretical “By The Book”, where you will hear the most optimal situations you can hope to achieve. These are good to know, so you can think about them when doing laundry. There are lots of good ideas in there.

Finally, we will go into real world tips to get closer to optimal, so you can save time and effort right away. 

This study was funded by Elizabeth P. Thank her for donating to study Efficient Laundry!

Engineering Theory- The Most Optimal (by the book)

Ergonomics is a hybrid of human health and engineering. This combines the mathematical and logic rigor of engineering to studies in humans. This data comes out as measurements, estimations, and best practice.

 

Enhancing Attention

One book suggested human attention is limited to ~30 minutes on a routine job. No reason to feel bad about getting bored of household tasks, you are only human.

Room Temperatures above 79 degrees are bad.

Work quickly, being motivated is proven to make you work quicker. Literally, thinking, can make you more Efficient. Rally! Don’t be weak!

Information Processing

Making a decision is fatiguing. Regardless if its trivial, the mind needs to see, understand, think, and convert into an output. It should be noted that after basic skills are obtained, people get better at speed.

Since these tasks require decisions, both in muscle control and mind, proficiency will happen with time. 

Best Practices- For Reach

A 5th percentile female can reach approx 2 feet, and this can be extended an additional 9 inches when standing.

Bending over is not desired. A rolling cart may help elevate baskets off the floor and ease transportation.

Motion is not desired, if you can grab multiple items per bend, you will save time and effort.

Another reminder, Motion is not desired, items that need to be put far away can be tossed aside. Hang up all necessary items, once.

Ergonomic Facts

Pulling motions are best done between 120 and 180 degrees, with best performance at 150 degrees. while pulling >120 degrees. This means its easier to pick items up below you, and put away higher. 

However, any sort of grabbing without bending over or reaching is encouraged.

Use a power grip! Instead of using fingers, use your fist to pick up.

Discomfort will cause inefficiency, even a 5cm/2in too high counter can cause shoulder pain.

Static, holding still, restricts blood flow and requires longer rest periods. Dynamic movement allows blood to circulate during relaxation. 

To reach further, bend your hip(8.2in/20cm) and rotate(1.8in/4.5cm) and extend shoulder(4in/10cm). Those are your 3 ways to extend. 

Conditions

For long tasks, if you can adjust between sitting and standing, this is preferred. Equipment exists to change the height level.

Sitting is better for blood flow.

Try not to hold the same position for more than 15 seconds, that is when lactic acid begins to build up.

Avoid moving/transportation to put something away.

Reduce or Increase Stress

Stress can be good, according to one book, a 10 is very stressful, a 3-5 stress is beneficial. 1 stress was bad. 

The arrangement of your workplace(dimensions, relative locations, etc…), makes a major contribution to how a task is handled. 

What are the accuracy requirements? Do things need to be folded/unwrinkeled? Could you change this to be happier doing laundry? Or make more challenging?

Is there flow? Work-rest cycles may be beneficial and for extended tasks, having start-stop times. 

Environment- Temperature, family/pets, surroundings.  

Reduce Boredom

One book had root causes of boredom, here is a take on how to make tasks less boring.

Short cycle times may be boring. Is there an opportunity for process flow?

A task with few opportunities for body movement gets boring, its okay to stretch/exercise muscles. 

Warm temperatures, could cooler temps get you motivated.

No coworkers. Does this mean we should be doing laundry with family?

People with high abilities and eager to excel find boredom, so next time you do laundry, try to be more Efficient. This is your new challenge, let us know if you find any discoveries. 

Dim work environment causes boredom. Changing color RGB light strips are a solution to boredom, or maybe the book intended to use brighter white light.

Real World Tips – Applied Efficiency

Here are applicable to everyone efficiency tips.

Sort Clothes Faster

Upon research, there are Efficient Comparison Sorting Algorithms. These can be used to sort your laundry faster. A take at Laundry Quicksort

  • Pick 2 items to collect, one for each hand. IE: Mrs Socks, Mrs. Underwear
  • Collect these with minimal digging, and put away
  • Put away large items that prevent seeing new items, don’t think too hard about this.
  • Continue with this routine, picking large quantities as a priority, and removing large items that inhibit seeing.

The goal here, limit motion like digging around and extended searching. Like Quicksort, your visible items are your ‘sorting set’, and items you cannot see are not sorted. All while picking up many items reduces the number of times you bend/turn to get clothes.

Hanging up clothes may be better separated into a different task. This is highly dependent on if you are sorting clothes near your closet and are near hangers. 

This asks the question, if laundry was done at the individual level rather than family level, would it be quicker due to less sorting?

Workspace Tips

Limit Transportation. Do your work within range if possible. Consider Swapping the contents of drawers to make sorting possible without taking steps. 

According to one book, locations of items should have priority- Most important items in front, then items by sequence(multi step items), then items by similarity, then frequency.

Turn Less, consider that turning your body is motion, if doing laundry on the bed causes you to turn significantly, consider sorting in a different location.  

Equipment

Note: this equipment suggestion is best practice, it serves to give you an idea what an Ergonomic Laundry Basket would be. Elevated, with wheels.

If you are interested, these are called Laundry Carts.

Even better, some laundry carts have false/auto adjusting bottoms to elevate laundry to make it easier to reach. Push laundry carts instead of pulling. Although changing muscle groups has economic advantages as well.

 

Next Steps

Get excited about doing laundry, like you never have before. I was shocked at how fast Quicksort had me putting away clothes. 

With 5 ergonomics books under my belt, I expect more household tasks to get optimized, and laundry to be further studied with MODAPTS, which are used to code task time like reaching and grabbing. They use this in Sweat Shop Sewing. 

 

Make More Efficiency

If we can reach 5,000 dollars, we are currently at 800 dollars, I will match and we can finance 2 interns to work 12 hours a week for 28 weeks completing studies that will help everyone.

The goal is to raise 5000 dollars to create more studies on Industrial Engineering Life.

Process Flow Charts- The Tool To Save Time Anywhere


Lead Engineer- Michael Kirk:

Saving 9 minutes a day for an entire year will give you an additional 54 hours to enjoy however you’d like.

This is a real world condition that was experienced for 3 years at my last living location. This allowed me to stay up later, enjoy my mornings fuller, and arrive to work earlier.

Save Time At Home-

In short, a Process Flow Charts lists every step to complete a Task, the list is reviewed for non-value added steps, and those steps are eliminated.

A Process Flow Chart is a necessary tool applied in every mass production environment. A Process Flow Diagram is best used anywhere a task is repeated often or consumes significant time.

A Life Process Flow Diagram

We apply Industrial Engineering to Life and conduct this real life study. For best results, You should go through your own process as normal, and a partner should either video record you, or write down every step and detail. The more mundane the steps, the more opportunities for optimization.

To Recap:

  • Prepare to record with Paper and Pen or Camera and preferably with a partner.
  • Start your Process as normal as possible, complete your process as normal as possible.
  • Write down every step along the way.
  • Review your list, marking each Step as Value Added, Necessary Non-Value-Added, or Non Value Added<
  • Look to eliminate Non-Value Added activities, or arrange them to limit the amount of time it consumes

There will be moments that you aren’t sure what you usually do next. This means your process is ‘Out-Of-Control’. By simply standardizing your process, you will begin saving time and have a benchmark to improve against.

Process Flow Chart- Example:

This Process Flow Chart starts in bed. Here is what was written down:

This was typed up in excel and the work began. We began classifying. Classifications to aid you in optimization. Don’t overthink it. Optimize and eliminate All Non-Value Added activities.

Value Added is when you get closer to your goal by doing a step. Non-Value-Added is when you accomplish nothing. Necessary Non-Value-Added is when a step does not create value, but is necessary to give you the ability to create value.

In a factory, Value Added Steps modify a part. In this example, modifying your body to prepare for the world. A Non-Value Added step in a factory would be picking up tools from another department. It doesn’t create value. Obtaining the tool is necessary, but the movement to get the tool may not be necessary. Turning on a shower does not make your body cleaner, but it is required as a step to get cleaner.

It was obvious during the process that time was wasted waiting for the shower to heat up. Anything that could be done before getting wet should be. This means that late night preparation may not be beneficial. Modifying the order, the steps choosing clothes and placing your phone in clothes are started immediately after the shower is started.

This simple re-arrangement eliminates the non-value added step of waiting for the shower and accomplishes tasks during this step.

Example Conclusion

3 minutes per day was saved in this example. Considering this was the morning routine of an Industrial Engineer, you will likely save even more time.

This is expected to save an additional 900 hours in life.

Instant Time Savings

Running this study in your own life will give you plenty of ‘Ah Ha!’ moments. Time that used to disappear will now appear in-front of your own eyes as non-value-added.

As you go through your own Process live, you will start seeing the waste. When you have completed the process, review, and optimize.

Implementation

Consider what Life Processes can be optimized. A morning routine, a bed time routine, getting home from work routine, recipes you make often, outdoor tasks, etc…

The detail of your process is up to you. The more Steps recorded, the more opportunities for optimization.

Pick a process and use this Process Flow Chart as a tool to visualize and eliminate waste.

Water Per Second – Save 1400 Hours In Your Lifetime Optimizing Water Transportation


Efficiency-Michael:

EDIT-This article is in need of an update

It was discovered waterbottles created a massive amount of trash and at least doubled the amount of time originally estimated. A gallon waterbottle is the new conclusion and the article will be updated in the future.


I first started writing this article and completely expected this to be a silly study like Capsaicin Per Dollar. I find it fun to play with math, so why not:

3 Things I didn’t consider before starting:

  1. Everyone must consume water, no exceptions. Ever.
  2. This is a non-trivial task that is difficult for any animal. We have plumbing.
  3. Water consumption happens daily, multiple times. This adds up over days, years, and lifetimes.

How to Save Time Drinking Water – The Data

Note: The time study was a single n=1 study. While exact oz/s will vary from situation to situation, everyone has similar situations. Transportation is often one of the largest hidden sources of waste, and it was found to be true for water.

Download Raw Data

Thoughts About The Data

Water dispenses out at pretty similar rates, with low flow water outlets being slightly slower.

Transportation is your largest waste of time. Having to fill 8 glasses of water a day adds up. Our goal will be to reduce transportation time.

The data is showing the advantages of leaving large cases of disposable water at your final destination. Despite having to walk down the isle at a grocery store, unpack the water from your vehicle, and dispose of water bottles, there are time savings over filling up your own water.

I bought my first case of water to conduct this study and my first thoughts on disposable water bottles as a product-

  • I lift weights and carrying water was seriously heavy
  • Both sides of the packaging ripped due to the heavy weight
  • In a single evening, I had 3 pieces of trash on my desk

Consider this could be my bias against environmentally harmful habits, but the time savings over Gallon Water Bottles is minor.

The Solution- Refillable Gallon Water Bottles

To visualize why Gallon Water Bottles are so effective at getting you water, consider how far away you are from a water source.

Making a round trip 8 times a day adds up to minutes per day, hundreds of hours in your life. Transportation waste is the largest time consumer. Optimize the tool for storing water to get 128 oz of water. Compared to 8oz cups of water, this is 16x less transportation. The largest time sink. Pareto?

We have been running with This water bottle for about 5 years.

Its big. You cannot feed this to a baby. There will be a day you spill this on you. Since water is pretty forgiving, I don’t mind it. Especially at 2am when you wake up needing water, in your mouth, right away. Disclaimer- As long as you arent stupid with it, it wont leak. After 5 years of use… We have… Trunk of Car…

Other 1 Gallon Options-

Drink out of gallon milk style containers? Not bad, but we did have one leak after a few months of use.

What About A Hose?

We are working on adding a hose for the new house. I highly recommend it, but apparently suburban culture isnt a big fan of hoses coming down from living room ceilings.

Will take pictures when its complete and beautified for suburban living rooms.

This has me visualizing a closet sized bathroom next to the couch… Living Room Urinal? The unfortunate part is that Misses Efficiency actually encourages this. I just need to decorate it up for the moms 😛

Protein Per Second Part 2- Cooking Proteins Fast, Reducing Effort


This article will reduce the cook time of your meals by minutes. Lots of engineering to explain WHY, but I will be sure to bold the tips on how to implement ways to cook food quicker. This uses Chicken for most studies, but this can be replaced with any other meat protein.

The Good-

This topic is going to have a LOT of tips on saving time cooking. The tips saved so much time, it messed with the data 😛

The Bad-

This data is ‘Out Of Control‘. Which means, the data isn’t significant. The data I post on this site is the highest mathematical quality I can possibly create, and I will not post bad data.

My Compromise

I will include the Protein Per Second, however I won’t post it in an Excel file format like I usually do.

Cook Protein Faster – By Method

Science would isolate this problem and find that throwing a few thousand pounds of chicken into Lava would be the fastest way. Engineering has to make this problem applicable. Grills, Stove Boiling, Stove Sauteing/Searing, and Slow Cookers are examined.

Eggs In 4 Minutes

0.11 g Protein Per Second

Methodology for all of these is common. Prep to Clean. Writing down process is something we do in Industrial Engineering.

  1. Take out small pan
  2. Turn on Medium High heat-(Getting anything hot is likely your “Long Lead Task”, do this as early as possible)
  3. Open Fridge, Take out Eggs
  4. Spray Pan with Nonstick
  5. Crack Eggs into pan
  6. Take out lid, place on pan(containing heat will speed up cooking)
  7. Wait 2 minutes, flip(Bonus if you can do this without dirtying a spatula, Minus points if this makes a mess you need to clean up)
  8. Place lid back on, wait another 2 minutes and serve
  9. Clean pan immediately under hot water to reduce sticking.

This can be done faster or slower depending on how you like your eggs cooked. I did this with 4 eggs with the goal of over medium-hard eggs. 27g protein, 4 minutes.

4 Eggs and 9 Sausages and Toast – Breakfast



27g + 21 + 8 g protein in 6 minutes =

0.155g Protein Per Second

Eggs were cooked in a similar way. Warming up sausages and toasting bread to make taste optimal added an extra 2 minutes in prep time. This included taking out 1 extra pan, 1 extra lid, opening and closing the freezer 2 times, and taking out an extra appliance.

The biggest thing to note- Sausages will cook in a similar time regardless if you have 2 or 10.

To understand why, I drew a picture that brought me back to our dreaded ME331 Fluids and Heat Transfer.

The heat from Electric Burner to Pan is a Heat Conduction(Qconduction). Conduction is Contact-To-Contact. Meaning surfaces need to touch completely. The browning of meats require Conduction and absence of water(we will get to that later). Protein touching the surface of the pan is getting more heat than protein that isnt touching the surface.

The air inside the pan is moving heat through Convection(Qconvection). Convection is the air and liquid flowing next to the protein. When you point a fan at you, there is no surface to surface contact, but the air will brush your skin and reduce your temperature.

Convection is especially strong with liquids, which we are going to see further in Boiling.

Keeping the lid on, means water in a pan cannot evaporate into your kitchen, instead water vapor circulates in your pan. If you take the lid off, the hot air and water vapor escapes

Summary:

Cooking food with a lid ON will cook faster.

Cooking food with a lid OFF will cook slower, but will brown your meat quicker.


(ugly) Chicken With Lid

781g of chicken, cooked in 8 minutes and 15 seconds. Barely brown. 242g protein makes this 0.49 g Protein Per Second.

Similar mentality as above, adding a lid will speed up the cooking process. Cooked on Medium High heat.

Calling it ugly because there is no browning. The Mailliard Reaction when the lid is on. Any moisture kills the browning that gives chicken flavor.

The Alternative:

Fajita Chicken

14 minutes for 1041g chicken. 312g protein and .37g Protein Per Second.

This is some beautiful cooking. Searing both sides of chicken for a near perfect Maillard Reaction. Adding a little vinegar to dissolve the brown Maillard bits stuck to the pan. Adding fajita seasoning and stirring.

Quality comes at a time price.

Boiled Chicken

Despite having massive amounts of convection because boiling water is surrounding chicken, water has a high heat capacity. Instead of cooking the chicken, the heat from the burner is being transferred to the water.

Below is a table for specific heats of materials. Water has a high specific heat, water is more dense than air, and there is significantly more mass to heat up than the same volume of air.

However… once the water is boiling, water is a better conductor of heat.

The most optimal way to boil chicken is to start the water, do something else, come back and drop the chicken in. There will be no mallard reaction, but very quickly chicken will be cooked.

Tip: Use the least amount of water you can get away with.

Oil is also a very popular medium of heat transfer because oil does not boil and can get hotter than water.

If you are going to use oil for frying chicken, take note that at high temperatures, low smoke point oils will begin to smoke and catch fire.

Slow Cooker Chicken

While this technically takes almost 4 hours, this is a favorite because most of this time is inactive. I am considering how to study this given the amount of meat depends on the slow cooker(and who really wants 5lbs of the same meal?). Here are two recipes that take less than 4 minutes to make.

Two recipes:

Pulled Chicken

  1. Turn on a slow cooker
  2. Add 1 Can of Soda Pop
  3. Add as much chicken you want

After 4 hours on high or 6 hours low, the chicken can be shredded and topped with BBQ sauce and placed on a bun or eaten plain.

Sunday Chicken

Here is the recipe, takes a tiny bit longer because there are more ingredients and I suggest cooking rice + veggies. However this is a lazy favorite.

Mass Produced Baked Chicken

1500g in 9.5 minutes =

.81 g protein per second

Cut the fat off and butterflied 1.5 pallets of chicken. 15 minutes in the oven at 350F.

This is potentially misleading because most people arent eating 1500g of chicken out of the oven. It also negates the time in the oven, similar to slow cooker chicken dishes. This was further packaged for later use.

The biggest takeaway: cooking in bulk pays off significantly.

It should be noted that both Ugly Lid On Chicken and Mass Produced Baked Chicken do not produce the Maillard Reaction.

Protein Shake

Homemade protein shake using Myprotin Impact (since it was my highest rated Protein Powder per dollar)

28g protein including milk in 1 minute flat.

.46g protein per second

This actually surprised me, I thought a protein shake would crush all competition. It seems that bulk production of food beats the competition.

Cooking food at a single time reduces the prep and clean up time.

Prep and Cleanup is a significant use of time on many proteins and I will continue to look to optimize further.

Next Steps To Eat Food Faster

An ultimate study of Protein Per Second, including fast food, street vendors, store rotisserie chicken and more is in the works. However different methods of home prep are going to be practically useful.

Tip- If you want to save time on any process, apply metrics to it and study each step. Your home chores will become more enjoyable and completed quicker.

My recommendation is to Meal Prep, the early data shows that is the best way to get as much food cooked in the shortest time

Save Time Eating – Optimize Food Consumption Without Changing Your Food


Lead Engineer- Michael Kirk:

This is a touchy subject with many people. How many times should you eat per day?

Does eating breakfast actually change your metabolism?

Does eating food after 9pm turn it into fat? (No. Excess calories turns into fat)

Should you eat 10 snacks a day? Should you eat once a day?

Eat Twice A Day – Intermittent Fasting

I’m not the first person to invent this concept, but I might be the first to use it to save time.

Shoutout to Daniel Engerer of Brainchild Engineering for pointing out my eating habits are Efficient.

How It Works

There are some guidelines for Intermittent Fasting, but I use it loosely.

  1. Eat 2 meals a day
  2. First meal should be after 16 hours of not eating(I usually do 12-14 hours)
  3. You can consume small amounts of calories(less than 100) outside of this time. Think small amounts of sugar in coffee.
  4. Expect the first 2-3 weeks to be difficult

Don’t treat these as rules, treat these as daily targets during your transition. Once you make the transition, you wont be hungry for breakfast, and you wont be hungry before bed.

Benefits- Save Time, Lose Weight

Depending on your goals, you might be interested in losing weight. Intermittent Fasting is a popular way to lose weight.

I’m a believer in Calories In = Calories Out.

The Calories you eat daily decides if you gain, maintain, or lose weight. Intermittent Fasting a technique to eat plenty of food ~2 times a day, and still lose weight.

There is no magic here, just structure. I count my calories, but eating 1,000 calories in a single meal psychologically feels good.

The Math, Save Time- 380 More Vacation Days In Your Lifetime

I’m going to assume ~10 minutes to consume your breakfast.

My first meal of the day is usually leftovers, and the process looks like this:

  1. Walk to Microwave- 0.5 Minutes
  2. Put food in Microwave- 2 Minutes
  3. Walk back to desk- 0.5 Minutes
  4. Eat Food- 5 minutes

Without getting into the details of putting food in a separate piece of Tupperware, putting in the dishwasher, taking out of the dishwasher, putting it away. I’m going to give that a value of 2 minutes. I’ve been told I eat fast, for estimation, I’m going to use 10 minutes.

This is 3,040 hours in your lifetime.

Implementation

As mentioned before, consistency is key. You can imagine a time in your life that you skipped breakfast enough times that you lost your appetite for breakfast.

If you are using this method to lose weight, I highly recommend a calorie counting app, I still use myfitnesspal, but it seems to be filled with push notifications/social media/ads.

One Last Tip- Make More Food

We are huge fans of making enough food for leftovers. We just Just-In-Time for our grocery shopping, and we don’t buy any groceries for Thursday. By Thursday, we usually have enough food in Tupperware that we have a quick dinner that can be microwaved in moments. If we somehow ate everything, we always have eggs in the refrigerator and make ‘Breakfast for dinner’.

If you are open to change your eating habits, I highly recommend this lifestyle. It saves time, it aids in losing weight, and it might save you money if you can skip eating out.

Shoes Per Hour – The Math For The Most Efficient Way To Put Shoes On


Engineer David Richelson conducted this study on Shoes Per Hour-

Shoes Per Hour – Fastest Ways To Put On Shoes

David- “There has to be a faster way!”

I spent about 3 months taking my shoes on and off at least twice a day. Every time I’d think to myself, “there has to be a faster way!” Since trying out different shoes and different laces, it turns out there’s not much I can do.

I’ve finished a time study on tying and untying my shoelaces, slip ons, shoe horns, and more. The most Efficient way to put on shoes.

Methodology

To keep it consistent, I would place my phone on the table in front of me, in timer mode, with my shoes in front of me. Then I would slip each shoe on, and tie them at my regular pace, being careful not to rush. I took four samples for each shoe for 7 different shoes: my personal dress shoes, my personal running shoes with standard laces, my personal running shoes with “Lock Laces”, basketball shoes, work shoes, running shoes with braided laces, and running shoes with standard laces. Ultimately what I want to know is: how much time does it take, on average, “per cycle”. In engineering, a cycle is when a given process is complete. In this case, a the process consists of putting the shoes on and then taking them off.

Tested Shoes

Dress Shoes

Puma w/ “Lock Laces”

And 1

Dr. Scholl’s

Athletic Works

Starter

Slip-on

Before I can discuss the results, I need to mention that my Puma shoes and the Starter shoes came with comically large laces (pictured below). It was unreasonable for me to single knot these shoes. Realistically, I’d double knot them, which is how I timed it. This added significant time to taking them off as well as putting them on.

Results

You can see from the chart below, that most tied shoes require relatively similar times to take on and off.

I suspect that the length of the shoelace has more to do with the time, than the profile. I was surprised to see that the Athletic Works shoes, which had a braided shoe lace, had no noticeable effect on the time.

The most dramatic difference was between my Pumas with the stock laces vs replacing them with “Lock Laces.” I shaved at least 15 seconds off putting them on! That’s the most relevant improvement for me, since I know that my motivation for working out is fleeting, and can easily evaporate in 15 seconds. But once I have my shoes on, I might as well work out.

For better or for worse, I’ve got the need for speed. Can I shave off any more time? I needed to think outside the box. I tried stylish slip on dress shoes for work, and velcro shoes for working out. My most inventive idea was leaving my dress shoes tied, and then pushing my feet into them with a shoehorn to assist me.

Slip-on shoes are the clear champion. It was almost too fast to measure. Since there’s no laces for either the Slip-ons, or my pre-tied dress shoes, timing the cycle consisted of just pushing them on. Here’s a quick video of how I timed it.

Switching to slip-ons would save me about 25 seconds per day. That’s worth 15 days vacation(120 hours) over the course of my life! Pushing my pre-tied shoes on did technically work, but it was destructive to the shoe and slightly painful for my feet.

When it comes to working out, I could commit the fashion faux pax of getting Velcro. But, I’ve gotta look stylish in the gym too.

At the end of the day, 25 seconds doesn’t sound like a lot. But it adds up over time. This was a great exercise and I can’t wait to apply these time study techniques to the next part of my life.

Michael Kirk- Shoes Per Hour

Utilizing David’s data, I just had to… I can’t resist 🙂

Efficiency’s Conclusion

I currently use Dress Shoes + Shoe Horn set up, but seeing that slip-ons are 2x faster, I’m going to be on the lookout for nice Slip-ons.

I haven’t tied a pair of shoes in memory and this data shows why. Tying your shoes takes 2x more time than using a shoe horn.

Thanks to David for completing this study to my Engineering Standards.

Pareto Your Hair- How To Save Time On Appearance With The Pareto 80/20 Rule


(Article Note: Much of this focuses on Female Appearance, I suggest all readers understand the methodology because the examples of female appearance will explain the Pareto Principle.)

Efficiency- Michael:

Mrs. Efficiency can be hostile to change. When I was experimenting and threw in chopped spinach to an Alfredo Sauce, she outright refused until she tasted it.

Last week she was dreading straightening her hair, a 30 minute task for her thick, straight/wavy hair. After some reluctance to a new idea, we found a way to save 23 minutes.

And… Husbands, I’m sure your Wives will love to hear that you have an idea to get them ready more quickly. /s

This is a very serious reminder- Change will require buy-in, its important to understand why.

Pareto Principle- 80% Of The Problem Comes From 20% Of The Sources

I’ve begun sewing, tailoring my own clothing, and making stuff. However, I ‘half-ass it’. I rarely use pins, and I draw dots rather than connecting lines.

My first time sewing I couldn’t believe how much time I spent preparing. I wondered if it was even necessary. After a trial run of minimal preparation, my shirt came out looking great. 80% of my shirt being too big had to do with the seam location, not the stretch or straightness of the seam. 20% of what I was actually spending time on was sewing a new seam.

Pareto Principle– 80% of the effects come from 20% of the causes. As a Process Engineer, we used this in our plant to decide which daily problems we’d focus on.

Technically-

‘I OneFifth-Ass It’

Save Time Straightening Hair

When I look at Misses Efficiency, I see the outside of her hair, and a little bit on the inside layers. 20% of the sources cause 80% of the problems.

We tested this, only straightening the outside of her hair.

As it finished I wasn’t that impressed, I thought she’d need to straighten more. She put some sort of oily spray in her hair, combed it, and her hair looked like a model’s.

The problem wasn’t that her heir needed to be straightened, the problem was that the outside of her hair needed to be straightened.

Sure, there are probably benefits from doing another 25 minutes of work. But in 7 minutes her hair went from Bed to:

Before

After

This took 7 minutes!

Save Time On Makeup

This is a topic worth studying on its own, however I’m 1 degree away away from understanding. I am unable to spend my commute thinking about if blush adds enough color to warrant the time. Or maybe Color is one of the most important things for appearance.

Ideas for variables to change.

  1. Limit yourself. Pick only a few pieces of makeup to put on. Change these every morning until you find some that work
  2. Pick one problem to knock out. Acne? Focus only on that? Or maybe Acne isnt a big deal and skin color makes a significantly bigger impact, skip the concealer.
  3. Skip fine details, rush through it, but put all of your makeup on. This eliminates the ‘careful’ time, maybe if you add enough makeup, you don’t need to be careful?

Change something every morning, or practice a method when you find something optimal.

Guy Hair

Do anything.

As most men dont do anything. 1-2 minutes of work puts you into the top 20%.

Engineers, Tailor Your Shirts

(Optional soapbox, but my shirts look great)

Engineers, I have been playing with a sewing machine and I’m going to put the knowledge of a 19 year old girl, a few Youtube Videos, and Misses Efficiency, in our terms.

If the sewing machine isn’t working, turn it off and turn it back on. Seriously- Reroute the threads completely. An engineer designed this thing and they made it pretty easy too. The manuals are well done and have tons of pictures with great work instructions.

I watched this 4 minute video about 4 times and I learned to tailor my first shirt. The first shirt turned out great and I’ve been tailoring through my wardrobe.

Hope you guys don’t mind the super casual photos, uh… Efficiency?

Hey this article broke with an update of the website.

The TL;DR is to download and try Spreed

It presents words so you dont need to move your eyes. This method is quite popular and many other apps exist, I use spreed myself for wikipedia articles.

Protein Per Second – Fastest Ways to Eat Protein (Part 1)


Version 2 is out. Change your life with ways to increase your protein per second. Protein Per Second 2- Optimizing Protein Per Second

Note: (This is version 1.0 of Protein Per Dollar, it’s more accurate than a buzzfeed article, however we havent completed an R&R style study, and isn’t ready for significant math applications. This is the conclusion off n=1, m=1.)

Protein is an unavoidable part of human life. Completing a detailed Obtain to Disposal time study may even have far reaching effects in food service and labor.

Engineering Time Studies

Deciding where to start the timer was difficult. Do we include Grocery shopping? Do we include the time it takes for me to get my clothing on? Do we include the time it takes to write a grocery list?

These are work in progress questions. End goal is to include every aspect from idea creation to disposal.

This article includes Prep and cleanup time of grocery proteins. This does not include acquisition time.

Fastest and Instantly Ready Protein

Obtaining Protein is different from most carbs and fats, meats have to be refrigerated and often cooked. These below are instantly ready, requiring no preparation.

Milk

If you can drink milk, its my top method to getting calories and protein.

Pros

  • Great Calories Per Dollar
  • Top Protein Per Dollar
  • Instant and Scale-able

Cons

  • Not a lean protein

Beef Jerky


Careful for highway robbery, this can be expensive. I’ve seen this for less than 4g protein per dollar.

Pros

  • Instant
  • Tasty
  • Lean

Cons

  • Expensive

Peanut Butter and Peanuts


Pros

  • High Calorie Per Dollar
  • Good Protein Per Dollar
  • Instant
  • Long Shelf Life

Cons

  • Not a Lean Protein

Honorable Mentions

Premade Protein Shakes, Cottage Cheese, Protein Bars, Greek Yogurt, Imitation Krab, and Veggies. Broccoli is ready to eat and has a few grams of protein in it. These items will make for some interesting math!

Quick Sources Of Protein

Not quite as fast, but these are probably some of your best overall values.

Protein Shakes


My personal favorite. Something so quick I often make it before work.

Pros

  • Top Protein Per Dollar
  • Lean
  • Less than 1 minute to make

Canned Meats

Tuna, Salmon, Spam, and more.

Pros

  • Ready as fast as you can open a can

Cons

  • Expensive
  • Often eaten with plenty of fat

Hard or Soft Boiled Eggs


Make as many as you can fit in a pan, eat it all week.

Pros

  • Great Protein Per Dollar
  • Great Calorie Per Dollar
  • Can be made in bulk
  • Low active time

Cons

  • Not A lean Protein

Lentils


Probably one of the easiest things to make

Pros

  • Boil, no stiring needed
  • A top Protein Per Dollar

Cons

Pinto/Black Beans

Depending on how hard it is to get your slow cooker out, this might be easier than lentils!

Pros

  • As much effort as the slow cooker
  • A top Protein Per Dollar

Cons

  • Not Lean Protein, high in carbs
  • May require flavoring

Best Time And Money Values

Creating dimensionless units and ranking by a formula:

Y= Protein Per Second/Protein Per Second(Minimum) * Protein Per Dollar/Protein Per Dollar Max

Until we gather enough data, I feel safe to list my top 5

  1. Protein Shakes- (potentially) Low cost, Fast, Lean Protein
  2. Canned Meats(Tuna)- Moderate Cost, Lean, Fast if your can opener ACTUALLY WORKS(mine doesnt…)
  3. Lentils – Top Protein Per Dollar, Low Effort
  4. Pinto Beans- Top Protein Per Dollar, Low Effort
  5. Boiled Eggs – Low Cost, Low Effort

Future Of Protein Per Second

See Protein Per Second 2- Optimizing Protein Per Second using Fluid Mechanics and Heat Transfer.

Combining Protein Per Second and Protein Per Dollar creates a unit Protein^2/Dollar*Second. Stay Tuned.

Mrs. Efficiency Thoughts – How To Stop Forgetting Things At Home


Article from Mrs. Efficiency- Dr. Mandy Kirk.


Efficiency- Michael:

Checklists are used in the factory to make sure things get done correctly 100% of the time. If you need to make sure a valve gets closed before we turn a pump on, Checklists prevent failure.

Before our factory developed a Start Up Checklist, I walked out of our Process Room to see a floor full of polyol to which our maintenance guy said- “Have you ever seen a grown man cry?”

Leaving home, I’d forget my lunch, belt, and work laptop often enough that Mandy told me we needed a solution. Its been 4 years and I haven’t forgotten anything since.

Now for Mrs. Efficiency:

People ask me if I like the efficiency lifestyle that Michael and I live. I do enjoy the benefits and it’s strangely calming. We’re always trying to alter our lives for the better. It makes me feel that we appreciate life more if we strive to maximize every second. Although we often end up watching Netflix with all of our time saving.

What to remember – List for the Door

I used to spend a lot of time in the morning getting to my car – only to realize I forgot something.


Phone, Wallet, Lunch, Homework…

We brainstormed the things we needed every morning. We wrote it all down, and stuck it on the door.
List1

And… We started using it.

At first I was reluctant, I’m stuck in my ways and tend to dislike change. But it helped Michael. He stopped forgetting things.

Then I stopped forgetting things.

And after a week or two I started to learn it and love it. Having every item written down and visible saves me time. Now I don’t even worry. I read through them, check each off in my head. 10 seconds and works every time.

Give it a try! Best case you will save yourself frustration and time. Worst case you are out a piece of paper.
