As can be seen, the IMC process is a series of five interlocking steps, providing a closed-loop investment and return system. That simply means that once the IMC planner has completed the fifth step in the process, that is, budgeting, implementation and evaluation, the process is designed to be repeated. That is why the IMC process is considered to be a continuous learning system that focuses on taking the results of the current marketing and communication programs, evaluates the results, and then uses those to identify changes or adaptations that should be made in the next series of communication efforts.
The best way to understand the IMC process is a walk through the methodology.
