Software product line evolution method based on kaizen approach

Continuing optimal product line development needs to evolve core assets in response to market, technology or organization changes. In this paper, we propose a product line evolution method based on the kaizen approach. Kaizen is a continuous improvement method that is adopted in Japanese industry. The important points of the kaizen are to prepare a work standard and continue to improve processes by correcting the differences between the standard and actual results. Our core asset kaizen method provides a standard that includes core asset types based on simple metrics, kaizen patterns representing expertise, and kaizen processes for continuous improvement.
