In an earlier post I called kaizen a numbers game. I've often been asked to explain that. Some people have the notion that we only want the really good ideas or improvements. The little ones are just not that important. This view is particularly prominent in the project setting. Projects are discrete. Once they end the team often disperses. In the construction setting, people go back to their companies only to be reassigned to another project and a new group of strangers. It's easy to see how someone can have the view that we don't have the time for anything but really big improvements.
Make a small change today
So, why do we seem to think that we don't have the time? In my experience it comes down to being overloaded and overwhelmed. Having too much to do and being in a bad mood about it is often the situation on projects. While there might be many sources for that situation, it doesn't need to prevail for the whole project. It may only take a commitment to make today better than yesterday.
