I don't know if smaller dishwasher loads are always bad.

Most dishwashers (and soap) are designed to remove food residue and the dishwasher is more energy efficient than doing a lot of rinsing in the sink before loading. They say to scrape off large chunks of food, of course, but not to rinse (rinsing wastes water).

If it takes many days to accumulate a full load, the food might be too stuck on to really get clean... so the members of the household might be tempted, then, to rinse their plates so the dishwasher can get them clean.

As with batches in different settings, the choice over an optimal load size isn't always straightforward or easy. Running a full batch (fully loading the machine) might not necessarily be the best approach.

That said, Lean has made me VERY intolerant of bad processes and inefficiency in stores and restaurants I frequent. I've learned, though, to not blame the individuals who are working in that bad system.

This post is a good example of how lean successes start, collecting irritaions.

The dishwasher irritation reminds me of the changes to big engine vehicles. You need a big truck to haul your boat. You are irritated by the amount of gas needed when you are not going to the lake, which is unfortunately the vast majority of the time. One solution was to shut down cylinders when the power is not needed. Another is to shut the engine off when at a stoplight.

An irritation is an unsatisfied need. 

Kevin- is this a personal example? My dad has a F250 truck for snow plowing and personal use. Your comments hit home when it doesn't snow for at least 6 months in Massachusetts and ridiculous amounts of money are spent on gas filling the giant truck. Moreover, though I do not know Joseph Rabinow, I think he is dead on.

John - my husband works in the construction industry as well.  I'm in the early stages of lean education with our health authority, and am constantly talking about it at home.  His ears perked up last night when I said 'why don't you look at it for your business?'  We starting looking for some 'Lean Construction' books.  There are a few but hard to know which ones were worth reading.  Do you have any recommendations?  Thank you :)

Sherri - there are several books that I would recommend.  Mostly, with construction you end up figuring out how to apply the manufacturing concepts to a construction environment.  Toyota Way and The Goal would be two of my top choices.  You can contact me directly if you want.  I'm not sure if I got my email correct on this post but it's jgroberts11@icloud.com.  I'd be glad to help. 

Tamara- it's pretty cool that even your kids appreciate 5s. i also use kanbans for grocery shopping by just ripping the label of what needs to be replished and taking it with me to the store. Is that the same idea for your pantry?

I know a guy who races at a local dirt track.  Last time I went to watch him, I sat in bleachers making a control chart of his lap times.  I don’t think he was quite convinced that understating variation was a secret sauce.

Also, dirt track races come to a complete stop after a yellow flag, and it can take quite a while to get all the drivers back in order for a restart.  It’s not unusual for this to happen several times during a 12 lap race.  Perfect scenario for batch reduction right?  Fewer cars on the track at one time means fewer accidents and less time to recover from accidents when they do occur.       

My local supermarket strangly placed its baskets next to where most people were exiting the store rather than entering, meaning you'd have to tangle with a lot of people going to opposite way in order to get a basket. I lost track of the amount of times I was tempted to go up to the information desk and suggest they move the baskets to the other side of the doors. I don't think most people wouldn't even give it a second thought.

On my last visit I noticed they had moved the baskets, but that was probably only to make way for the Xmas tree that's now up. I expect they'll move them back in the New Year!

This is an environmental issue. People knowingly over comsuming the resources is detrimental to PLANET EARTH!

I really think there are some limitations for Lean if we visualise it in our every aspect of lives. It drove me crazy since I was soaked up in Lean in my initial days. (I used to think and apply every aspect of my life, from brushing teeth to sleeping on the bed which is only used at the night) 

Waste categorisations are universally applicable in any case of our society, and Danielle your article really nicely throw on the same issues. But do you think the bigger picture as a Social system as a whole is evolving since many centuries, may be not all the solutions seems perfect to scale in lean. I am not articulating much in detail about the social system, but issues raised by you are valid and many more others.

What astounded me that I missed the "what is the value?", as a every individual person has different value system for every aspect ofour social systems. If everyone is on board with the common Value propositions, there can be tremendous acceleration in waste reduction from our social systems. Until then their are and will be pockets of waste production.

Work was routine and boring. When given the opportunity to innovate at work, I leapt at the chance. Soon I realized the hardest part of lean was to find a problem to solve. I learned to look for irritated people, coworkers, customers, managers, etc. An irritation meant something needed fixing. This process became a subconscious routine.

Off the job, while playing with my favorite teammates, bird dogs, I was irritated with my shooting. I was letting my teammates down with my performance. This irritation made me realize the innovation skills learned on the job could be used to improve products off the job. My company's first product can be viewed at:

When my dogs hear a shotgun blast, they now know there is a bird to retrieve. Lean hasn't ruined my life. It has set me free. My passion for lean is making my hobby an occupation.

My path can be replicated. All you have to do is what this post did, share irritations.
