The Japanese Strategy of Continuous Improvement
What is Kaizen?
Kaizen means "improvement". Kaizen strategy calls for never-ending efforts for improvement involving everyone in the organization – managers and workers alike.
Kaizen and Management
Management has two major components:
1. Maintenance, and
2. Improvement.
The objective of the maintenance function is to maintain current technological, managerial, and operating standards. The improvement function is aimed at improving current standards.
Under the maintenance function, the management must first establish policies, rules, directives and standard operating procedures (SOPs) and then work towards ensuring that everybody follows SOP. The latter is achieved through a combination of discipline and human resource development measures.
Under the improvement function, management works continuously towards revising the current standards, once they have been mastered, and establishing higher ones. Improvement can be broken down between innovation and Kaizen. Innovation involves a drastic improvement in the existing process and requires large investments. Kaizen signifies small improvements as a result of coordinated continuous efforts by all employees.
Process-Oriented Thinking vs. Result-Oriented Thinking
Kaizen concentrates at improving the process rather than at achieving certain results. Such managerial attitudes and process thinking make a major difference in how an organization masters change and achieves improvements.
