- Accountable – final approving authority, only one per task, must also ensure ensures the prerequisites of the task are met
- Consulted – provide recommendations or opinions, typically subject-matter experts

## RASCI model
- + Support – helps to complete the task

## RACI-VS
  - **Verifier**: The role responsible for checking that the product meets certain criteria or standards.
  - **Signatory**: The role responsible for authorizing the work before it proceeds or is considered complete.

## CLAM Model
Another variation similar to RACI:
  - **Contributes**: Those who contribute to or provide input for the activity.
  - **Leads**: Those who lead and ensure the task is executed.
  - **Approves**: Those who approve or review the work.
  - **Monitors**: Those who monitor progress and ensure compliance and standards are met.

## RAPID
More geared towards clarify decision-making roles, seemingly in a consultancy workmode.

- R = Recommend – gathers relevant input and proposes a course of action, possible alternatives, pros and cons
- A = Agree – formal approval of a recommendation; A and R work together to come to a mutually satisfactory proposal for the Decider.
- P = Perform – executes or implements the decision once it is made. Good practice is to involve them early in the process to gather input.
- I = Input – provides relevant information to the Recommender and Decider. More narrow in scope than Recommenders, who should consider all input.
- D = Decide – single person ultimately accountable for making the final decision, committing the group to action and ensuring the decision gets implemented.
