What according to the members of thjis group is a successful way of capturing re-usable knowledge from lean projects/kaizens ? Also, what's the key to ensure that such knowledge is actually "re-used" so that wheels are not re-invented ? Can someone share any template in this regard ?
I can not speak specifically for Lean or Kaizen, but when I did improvement projects I made out a project plan, kept it updated and kept records of updates. I decided upon measureables (before, during and after measurements) and monitored them over time.
Any time I am involved in an improvement project the combination of measureables and project plan produces information/data. Record all the information/data and keep it consolidated in a 'file' so it is easy to look at a project and the results. Years ago I used 3 ringed binders. These days you can easily use a computer directory.
I can't give you a key to
ensure that such knowledge is actually "re-used" other than to incorporate what is shown to work into the appropriate system(s) via procedures and/or criteria and to require that future projects look to past projects in their preparation stage.
It's much like problem solving. You have a problem. You develop a plan to investigate the problem. Part of that plan is to research prior times that the problem, or a similar problem, occurred. You find a solution. Along the way you document what you do/try. You record what fails to work as well as what appears to work. From that you look to see if there are other places where the same, or a similar, process is in use and you apply the solution there as well.
