PRECEDE: Predisposing, Reinforcing, and Enabling Constructs in Educational/ecological Diagnosis and Evaluation; 
PROCEED: Policy, Regulatory, and Organizational Constructs in Educational and Environmental Development
PRECEDE has four phases:

Phase 1: Identifying the ultimate desired result.
Phase 2: Identifying and setting priorities among health or community issues and their behavioral and environmental determinants that stand in the way of achieving that result, or conditions that have to be attained to achieve that result; and identifying the behaviors, lifestyles, and/or environmental factors that affect those issues or conditions.
Phase 3: Identifying the predisposing, enabling, and reinforcing factors that can affect the behaviors, attitudes, and environmental factors given priority in Phase 2.
Phase 4: Identifying the administrative and policy factors that influence what can be implemented.

Another premise behind PRECEDE-PROCEED is that a change process should focus initially on the outcome, not on the activity. (Many organizations set out to create community change without stopping to consider either what effect their actions are likely to have, or whether the change theyre aiming at is one the community wants and needs.) PRECEDEs four phases, therefore, move logically backward from the desired result, to where and how you might intervene to bring about that result, to the administrative and policy issues that need to be addressed in order to mount that intervention successfully. All of these phases can be thought of as formative.
PROCEED has four phases that cover the actual implementation of the intervention and the careful evaluation of it, working back to the original starting point “ the ultimate desired outcome of the process.

Phase 5: Implementation “ the design and actual conducting of the intervention.
Phase 6: Process evaluation. Are you actually doing the things you planned to do?
Phase 7: Impact evaluation. Is the intervention having the desired impact on the target population?
Phase 8: Outcome evaluation. Is the intervention leading to the outcome (the desired result) that was envisioned in Phase 1?
