Changes can be made by developers, installers, or end users, and these changes need to be prepared for. There is a cost of preparing for change as well as a cost of making a change. The modifiability tactics are designed to prepare for subsequent changes. Tactics to reduce the cost of making a change include making modules smaller, increasing cohesion, and reducing coupling.
