How would I recognize when a Kaizen event is necessary and when it might be overkill or even not worth the effort for marginal benefits? Are there tools I could use to check that or would I have to rely on the experience of my manager and in time, my own?
In my opinion, the best way to know if a company requires a Kaizen event is whether the process is living up to its potential. In other words, there might be a possibility for the company to work and achieve better productivity but they have not realized it yet. I think it all comes down to experience, and working and observing there regularly.
