RACI and RAPID solve different coordination problems. Use RACI to clarify responsibility for work. Use RAPID to clarify roles in a consequential decision. A team can need both: RACI for the workflow and RAPID for the decision gate inside it.

This guide provides a comparison, a six-question selection test and a copyable matrix for cross-functional teams.

RACI and RAPID in one table

Question RACI RAPID
Primary purpose Clarify participation in activities and deliverables Clarify accountability in a decision
Roles Responsible, Accountable, Consulted, Informed Recommend, Agree, Perform, Input, Decide
Best unit of analysis Task, process step or deliverable Named recurring or high-value decision
Final authority Accountable person owns the result, but decision mechanics may remain implicit Decide role explicitly makes the decision
Main risk Too many consulted people and ambiguous accountability Too many agreement rights and a slow decision path
Best use Repeatable workflow with clear outputs Cross-functional choice with material trade-offs

Bain & Company describes RAPID as a proprietary tool for clarifying decision accountability among multiple stakeholders. Its five roles are Recommend, Agree, Perform, Input and Decide. Bain also cautions that not every decision merits this level of explicit design; high-value or high-frequency decisions are the natural starting point.

RACI is a responsibility-assignment matrix. It is most useful when a team needs to see who performs work, who owns completion, whose advice is required and who needs the result.

The DECIDE-6 selection test

Before building a matrix, answer six questions.

Test Diagnostic question Choose RACI when... Choose RAPID when...
D - Decision Is the core object a task or a choice? The object is a deliverable or process step The object is a specific choice with alternatives
E - Exposure What happens if the team gets it wrong? Rework is bounded and recoverable Financial, legal, safety, customer or strategic exposure is material
C - Cross-functional tension Do functions have competing mandates? Handoffs matter more than trade-offs Trade-offs require explicit agreement or input
I - Irreversibility Can the result be reversed cheaply? Changes are routine Reversal is costly or reputationally difficult
D - Decision frequency How often does this recur? The workflow repeats frequently A recurring decision deserves a stable decision architecture
E - Executive escalation Is escalation currently arbitrary? Escalation follows operational ownership The final decider and agreement rights must be visible

If four or more questions point to RAPID, design the decision first. If most point to RACI, design the workflow. If the result is mixed, use a combined model.

A combined decision-rights matrix

Copy this structure and replace the example roles.

Work or decision object Responsible / Perform Accountable / Decide Recommend Agree Input / Consulted Informed Evidence required Decision deadline
Define business requirement Product owner Business sponsor Product owner - Users, operations Technology Approved problem statement 5 Sep
Assess security risk Security analyst CISO delegate Security lead Legal Vendor, procurement Sponsor Risk assessment and gaps 12 Sep
Select AI vendor Procurement lead Executive sponsor Joint evaluation team Legal, security Finance, users Operations Scorecard, residual risks, commercial terms 18 Sep
Implement controls Delivery manager Technology owner Security lead - Vendor, legal Sponsor Test results and owner register 10 Oct
Approve production use Technology team performs Executive sponsor decides Product owner Security, legal Risk, operations Affected users Release evidence and rollback plan 15 Oct

The combined table prevents a common error: assigning the same person “Accountable” for a workflow and assuming that this automatically defines authority for every decision inside it.

Worked example: approving an AI vendor

Suppose procurement owns the sourcing process, technology owns integration, security owns risk analysis, legal owns contract review and the business sponsor owns the outcome.

A RACI-only design may make procurement Responsible and the sponsor Accountable. That helps the workflow, but it does not answer whether security can veto deployment, whether legal agreement is mandatory or whether the sponsor can accept residual risk.

A RAPID layer makes those rights explicit:

  • Recommend: joint product, procurement and technology evaluation team;
  • Agree: security and legal for defined non-negotiable thresholds;
  • Perform: procurement and implementation teams;
  • Input: finance, privacy, users and operations;
  • Decide: named executive sponsor within an approved risk-acceptance boundary.

The design is not finished until the evidence threshold is explicit. For example: a completed security assessment, tested data-flow diagram, contractual data-use limits, cost model, human-oversight design and rollback plan.

Seven matrix rules that preserve speed

  1. Name the object precisely. “AI strategy” is too broad; “approve customer-data use for the support assistant” is a decision.
  2. Allow one final decider. A committee without a named decision role creates hidden vetoes.
  3. Limit agreement rights. Agreement is not a courtesy copy; it should protect a defined policy, legal or risk boundary.
  4. Separate input from approval. Experts can provide evidence without owning the final trade-off.
  5. Attach evidence. A role label without an evidence requirement does not improve decision quality.
  6. Add a deadline and escalation path. Time is part of decision design.
  7. Review recurring matrices. Roles should change when the operating model, risk or regulation changes.

A simple complexity check

Use this diagnostic before adding another stakeholder:

Coordination load = consulted/input roles + 2 x agreement roles + 3 x final deciders

One decider, two agreement roles and four input roles produces a load of 11:

4 + (2 x 2) + (3 x 1) = 11

The number is not an industry benchmark. It is an internal warning device. If two similar decisions have loads of 11 and 22, ask whether the second genuinely needs twice the coordination or simply inherited unnecessary participants.

Put the matrix into an operating system

A responsibility matrix should not live as an isolated slide. Connect it to a decision record, meeting cadence and review date. The Executive Decision Log Template provides a compatible record for assumptions, evidence, ownership and reconsideration thresholds. For one-to-one delegation rather than cross-functional decisions, use the five-level delegation matrix.
