Many types of quality assurance activities, to give you an amazing amount of information about your opportunities to improve the quality of the created product. But this information alone does not guarantee the desired quality. You have a special way to put into practice all the things you’ve learned. For example, if your design process is inefficient for use on certain types of projects, then you need to develop an alternative process and use it on all future projects of this type.
On a regular basis (annually, monthly, daily) to consider new ways to improve your standards, processes and practices and make necessary adjustments. Plan for this special time and assign responsible people, otherwise this type of activity simply does not make sense.
In the end, at the beginning of a new project just turn around and take back lessons learned from previous projects. Browse the knowledge base of experience (LessonsLearned) and a history of defects and determine what needs to be improved, based on analysis of past projects. What action can be taken at this time, to ensure a better quality product than what has been achieved to this point? Moreover, it should be done at the start of each new project, otherwise it will be skipped under the onslaught of new projects.
