Implement selected action proposals developed in causal analysis.


Action proposals describe tasks necessary to address root causes of analyzed outcomes to prevent or reduce the occurrence or recurrence of negative outcomes, or incorporate realized successes. Action plans are developed and implemented for selected action proposals. Only changes that prove to be of value should be considered for broad implementation.

Example Work Products

  1. Action proposals selected for implementation
  2. Action plans


1. Analyze the action proposals and determine their priorities.


Criteria for prioritizing action proposals include the following:
  • Implications of not addressing the outcome
  • Cost to implement process improvements to address the outcome
  • Expected impact on quality

Process performance models can be used to help identify interactions among multiple action proposals.

2. Select action proposals to be implemented.

Refer to the Decision Analysis and Resolution (DAR) (CMMI-DEV) process area for more information about analyzing possible decisions using a formal evaluation process that evaluates identified alternatives against established criteria.

3. Create action plans for implementing the selected action proposals.


Examples of information provided in an action plan include the following:
  • Person responsible for implementation
  • Detailed description of the improvement
  • Description of the affected areas
  • People who are to be kept informed of status
  • Schedule
  • Cost expended
  • Next date that status will be reviewed
  • Rationale for key decisions
  • Description of implementation actions

4. Implement action plans.

To implement action plans, the following tasks should be performed:

  • Make assignments.
  • Coordinate the people doing the work.
  • Review the results.
  • Track action items to closure.
Experiments may be conducted for particularly complex changes.


Examples of experiments include the following:
  • Using a temporarily modified process
  • Using a new tool

Actions may be assigned to members of the causal analysis team, members of the project team, or other members of the organization.

5. Look for similar causes that may exist in other processes and work products and take action as appropriate.
