Costs associated with modifying software are a large part of an organization's software development budget. Since change is to be expected, the costs associated with change can be reduced by preparing for it. Software design patterns associate a problem and context with a solution to document good design practices. Patterns allow software designers to evaluate solutions in terms of the aspects of the system most likely to vary. This article uses the INgageTM Intelligent Peripheral Prototype to demonstrate how the use of two patterns, Layers and Mediator, facilitated a major change to the protocol stacks, and isolated object interactions to make them more maintainable
