In last week’s blog, I shared with you the importance of categorizing your process problems and the first four types of waste in process: waiting, motion, inventory, and overproduction. Today I’ll be sharing the last four categories into which process problems can fall.

Looking at problems as a category helps us see based on fact and logic — what is happening in the operation. It makes it about the operation, not the person or a specific department, which is one of the principles of this work in process improvement. Here are the remaining types of waste in process:

#7 Non-utilized talent

If you have someone in a role where they’re actually more qualified to do more, that’s a form of waste. Underutilizing your people’s talents, skills, and knowledge is a form of waste. For example, an executive assistant who is highly competent in strategy, innovation, and leading teams is stuck doing…
