DIAGNOSIS: understanding the real problem
With an adequate definition in hand, the change agent and the system can begin to reach out for resources that might be relevant. "Resources" come in many forms: people, finances, space, time, technology, and knowledge , especially knowledge of other change efforts, successful and otherwise. Just plain ideas can also be useful resources.
With a well-defined problem and an assemblage of relevant resources, the system is in a good position to choose a solution or a set of possible solutions.
The planned change model is inserted in the larger context of an on-going change strategy, both for the change agent and for the client system.
