14. Typical design steps

1. Find the concepts/classes and their most fundamental relationships.

2. Refine the classes by specifying the sets of operations on them.

   • Classify these operations. In particular, consider the needs for construction, copying, and destruction.

   • Consider minimalism, completeness, and convenience.

3. Refine the classes by specifying their dependencies.

   • Consider parameterization, inheritance, and use dependencies.

4. Specify the interfaces.

   • Separate functions into public and protected operations.

   • Specify the exact type of the operations on the classes.

• Needless to say that these are steps should be an iterative process!
