A filosofia japonesa do aperfeiçoamento progressivo:

Kaizen (改善, Japanese for "improvement") is a Japanese philosophy that focuses on continuous improvement throughout all aspects of life. When applied to the workplace, Kaizen activities continually improve all functions of a business, from manufacturing to management and from the CEO to the assembly line workers.[1] By improving standardized activities and processes, Kaizen aims to eliminate waste (see Lean manufacturing). Kaizen was first implemented in several Japanese businesses during the country's recovery after World War II, including Toyota, and has since spread to businesses throughout the world.[2]

Kaizen is a daily activity, the purpose of which goes beyond simple productivity improvement. It is also a process that, when done correctly, humanizes the workplace, eliminates overly hard work ("muri"), and teaches people how to perform experiments on their work using the scientific method and how to learn to spot and eliminate waste in business processes.
To be most effective kaizen must operate with three[
citation needed] principles in place:
consider the process and the results (not results-only) so that actions to achieve effects are surfaced;
systemic thinking of the whole process and not just that immediately in view (i.e. big picture, not solely the narrow view) in order to avoid creating problems elsewhere in the process; and
a learning, non-judgmental, non-blaming (because blaming is wasteful) approach and intent will allow the re-examination of the assumptions that resulted in the current process.
People at all levels of an organization can participate in kaizen, from the CEO down, as well as external
stakeholders when applicable. The format for kaizen can be individual, suggestion system, small group, or large group. At Toyota, it is usually a local improvement within a workstation or local area and involves a small group in improving their own work environment and productivity. This group is often guided through the kaizen process by a line supervisor; sometimes this is the line supervisor's key role.
While kaizen (at Toyota) usually delivers small improvements, the culture of continual aligned small improvements and standardization yields large results in the form of compound productivity improvement. Hence the English usage of "kaizen" can be: "continuous improvement" or "continual improvement."
This philosophy differs from the "command-and-control" improvement programs of the mid-twentieth century. Kaizen methodology includes making changes and monitoring results, then adjusting. Large-scale pre-planning and extensive project scheduling are replaced by smaller experiments, which can be rapidly adapted as new improvements are suggested. -
