Any action whose output is intended to be an improvement to an existing process.
Kaizen Events are commonly refered to as a tool that:
1) Gathers operators, managers, and owners of a process in one place
2) Maps the existing process (using a deployment flowchart, in most cases)
3) Improves on the existing process
4) Solicits buy-in from all parties related to the process
Kaizen Events are an extremely efficient way to quickly improve a process with a low Sigma score. Kaizen Events are also useful for convincing organizations new to Six Sigma of the methodology’s value.
The true intent of a Kaizen Event is to hold small events attended by the owners and operators of a process to make improvements to that process which are within the scope of the process participants.
