Masaaki Imai developed Kaizen, which are small incremental changes made to continuously improve productivity and minimize waste. The main principles of Kaizen are to consider the process and results, look at the entire job process to find the best way to get the job done, and make improvements without blame. Kaizen is widely applicable, results-oriented, a learning experience, and team-based. The phases of Kaizen are to select an event, plan the event, implement it, and follow up.
