- Analyzing communication problems
- Establishing performance objectives that, when achieved, address these objectives
- Developing a blueprint for a communication effort to address those objectives
- Developing the components of the planned communication effort solution
- Evaluating the ultimate effectiveness of the effort
Saul expands on this definition in his article on information design.
