Red Team Review: Standalone Application of the Red Team Protocol

A rapid, confidential, adversarial assessment of a single strategic plan, investment thesis, or M&A rationale. The Red Team Protocol, the core SGaaS tool, applied as a discrete standalone engagement.

What the Red Team Review Is

The Red Team Review is the standalone application of the Red Team Protocol™, the continuous adversarial tool at the core of SGaaS, applied to a single strategic decision, investment case, or governance question. The methodology and intellectual foundation are identical to those used within Retained and Embedded engagements; the difference is scope. The Review concentrates the protocol on one decision rather than deploying it continuously across the governance cycle.

Why It Has to Come From Outside

Asking an internal team to attack the plan they built puts them in an impossible position. They report to the people whose judgement is under examination, and the cost of being the one who says so is real and lands on them personally. An external principal has no such exposure. Challenge is the contracted deliverable, so producing it carries no career risk, and the absence of that risk is what makes the output worth reading.

How the Four Weeks Run

Analysis. The principal works through the board papers, the model, the diligence material and whatever else the case rests on, then sets out what the decision assumes and how well the evidence supports each assumption. This is desk work, done without occupying the deal team.

Private positions. Before any findings circulate, each director records their confidence in the key assumptions, the risks they consider most material, and what would change their mind. These reach the principal directly and stay anonymous in the aggregate.

The session. The Challenge Memo goes out with the aggregated positions alongside it, and the board works through both in a facilitated discussion. Sometimes the two line up, which is itself worth knowing before a large commitment. More often they diverge on something specific, and that gap is what the session is for.

What the Review Delivers

  • A Challenge Memo documenting the decision’s key assumptions, the evidentiary basis supporting each, and the conditions under which each would fail.
  • An aggregated pre-deliberation map comparing directors’ prior confidence with the adversarial findings.
  • A facilitated structured debate session that operationalises the third phase of the protocol.
  • A prioritised list of remediation actions, identifying what would need to change in the decision, the evidence base, or the supporting analysis to materially reduce the documented fragility.

If You Are Not on a Retainer

The Review is the lowest-commitment way to test whether this is worth doing. One decision, four weeks, a fixed scope, and an output the board can judge on its merits. Boards that find it useful usually move to Retained SGaaS, where the same protocol runs continuously across the governance cycle. Boards that stop here have still spent four weeks learning something about a live commitment.

The cadence at which the protocol runs inside each tier is set out on the Adversarial Methodology page.

When to Commission a Red Team Review

  • Before a material capital commitment, acquisition, divestiture, or market entry.
  • Before a strategic plan is taken to the board for approval.
  • Before an investment committee final vote on a transaction of significance.
  • When the board senses that an emerging consensus has not been seriously tested.
  • When the cost of an unexamined assumption would be material.

Principal-Led Delivery

Marentis Labs maintains a small number of concurrent retained engagements to ensure principal-level delivery on each. If you are considering a governance mandate, an early conversation is advisable.
