A similar process can be triggered by the identification of a design defect during system testing. Sometimes design inspections can also result in the identification of positive patterns, either by recognizing a particularly neat solution to a particular design problem, or when the inspector proposes an alternative solution to an identified design defect. However, until people have considerable experience with patterns, it is difficult to define patterns that are sufficiently clear and generic to be useful. Pattern Usage Workshops Designers are invited to a pattern usage workshop, to display and discuss their use of patterns within their own work. There are three main objectives for this workshop.
Designers receive encouragement and recognition for their good use of patterns.
Designers share knowledge and ideas about what patterns are appropriate, and how they can be used. Pattern managers discover any opportunities, gaps or shortcomings in the usage of patterns. Pattern workshops are held at intervals during the pattern programme, so that the increasing usage of patterns can be monitored and encouraged, and pattern usage can be reinforced. Where a particular negative pattern has been recognized as a common bad practice within current design practice, you need to provide positive advice to designers. Instead of doing X, do Y. Y is now a positive pattern.
