Continuous improvement is one of the most important concepts for improving quality. Continuous improvement has long been a key part of Japanese-style quality systems like the ones used by Toyota and Sony.

Based on these pre-ISO quality systems, the first step in improving quality is to standardize all company processes. Random processes yield random results so it is difficult to continuously improve random processes. Once the companies' processes have be standardized using ISO 9001 compliant procedures, the next step is to evaluate the processes and  use this information as feedback to improve the processes. This closed-loop system uses the feedback as input to the corrective and preventive actions system and the management review meetings. These 2 systems apply resources to fix the problems and improve the quality of the products, processes and even the quality of the quality system. 

For non-ISO 9001 certified companies, continuous improvement is still the key reducing cost, improving quality and improving the profitability of the company. If you only implement one concept from this website, it should be continuous improvement.
