A software component exhibits generality if it can perform its intended functions without any change in a variety of situations. General software components are more difficult to design than less general components. They also usually run slower when executing. However, such components:
- Are ideal in complex systems where a similar function must be performed in a variety of places.
- Are more potentially reusable in other systems with no modification.
- Reduce maintenance costs for an organization due to reduced numbers of unique or similar components. Think about the hassle of maintaining multiple different repositories and build plans.
When decomposing a system into its subcomponents, stay cognizant of the potential for generality. Obviously, when a similar function is needed in multiple places, construct just one general function rather than multiple similar functions. Also, when constructing a function needed in just one place, build in generality where it makes sense - for future enhancements.
