PoC sign-off checklist

Practical items to work through across 7 steps, to move a PoC forward to internal approval.

Available in Japanese only: this checklist is currently published in Japanese only. The overview below is in English, but the full 37-item checklist has not yet been translated.

This checklist organizes, in 7 steps, the practical items to prepare before proposing a PoC (proof of concept) for a large enterprise or new venture, so it can win internal sign-off. It runs from clarifying the purpose, through narrowing the hypothesis, confirming integration with existing systems, staged budgeting, go/no-go criteria, steering, and team structure.

It avoids language tied to a specific technology or product, and organizes points generally worth knowing from the perspective of someone drafting an internal proposal. It does not guarantee an outcome — use it as a starting point for internal discussion.

• Section 2: Step 1 — Clarifying the purpose and problem (5 items)
• Section 3: Step 2 — Setting 1–3 hypotheses to test (5 items)
• Section 4: Step 3 — Confirming the scope of integration with existing systems (6 items)
• Section 5: Step 4 — Staged budgeting and the sign-off flow (6 items)
• Section 6: Step 5 — Go/no-go and exit criteria (5 items)
• Section 7: Step 6 — Steering and progress-sharing (5 items)
• Section 8: Step 7 — Team structure (5 items)

Step 1: Clarifying the purpose and problem

Purpose: put into words, at a level a sign-off reader will understand, what the PoC is meant to establish. The first question a sign-off process asks is "why is a PoC needed?" Before explaining the technology, aim to be able to state the business problem and the question the PoC should answer in 1–2 sentences.

• The business problem to solve can be explained in 1–2 sentences
• The question the PoC is meant to answer (whether to move to production) is clear
• You can explain why now is the right time to verify this
• The impact or opportunity cost of not running the PoC is organized
• Related existing businesses and departments have been identified

Step 2: Setting 1–3 hypotheses to test

Purpose: narrow the hypotheses and set a PoC scope that can be explained in a sign-off request. Too many hypotheses inflate the verification period and cost, and make sign-off harder to obtain. Narrowing to hypotheses that connect directly to a production decision — 1 to 3 of them — makes the scope and cost easier to justify.

• The hypotheses being tested are narrowed to 1–3
• Each hypothesis has a defined "condition for saying it was verified" (an evaluation metric)
• The hypotheses connect directly to a production decision (hypotheses that would not inform a decision have been excluded)
• The hypotheses are prioritized
• The measurement method for each evaluation metric is decided

Step 3: Confirming the scope of integration with existing systems

Purpose: document, at the sign-off stage, the integration points that tend to cause rework at the production-migration stage. Confirming the integration scope and test method during the PoC stage reduces the risk of additional cost and schedule delay later.

• The scope of existing systems to integrate with during the PoC is identified
• The IT department has confirmed the API/data access needed for integration
• It has been confirmed whether integration can be verified in a test environment with dummy data
• The additional work expected for production integration is roughly understood
• How data (personal or confidential information) will be handled is organized
• The confirmation flow with the IT and security departments is understood

Step 4: Staged budgeting and the sign-off flow

Purpose: make it easier to get approval even before the total cost is settled. The dilemma of "sign-off won't happen until the full cost is fixed" can often be eased by splitting the request into concept, PoC, and production stages, each scoped so a decision can be made on its own.

• Cost ranges are organized across the three stages: concept, PoC, production
• The PoC-stage budget is broken into a unit that is easier to get approved
• Candidate budget categories (department budget, new-venture budget, subsidy, etc.) are identified
• The sign-off approval route (decision-maker, co-approvers) is understood
• Deliverables for each phase and the condition for moving to the next are organized
• The assumptions behind the estimate (scope, timeline, team) are documented

Step 5: Go/no-go and exit criteria

Purpose: decide the decision criteria before starting, so a decision to stop can also be made after the PoC. Setting go/no-go conditions before starting avoids getting stuck unable to decide to stop, and including exit criteria in the sign-off request makes it easier to present as a plan that limits downside.

• The condition for a "go" (move to production) decision is defined
• The condition for a "no-go" (revise or discontinue) decision is defined
• The timing of the decision (mid-point, at completion) is decided
• The learnings or reusable outputs to preserve in case of exit are organized
• The decision-making body and decision-maker are decided

Step 6: Steering and progress-sharing

Purpose: design a progress-sharing mechanism where senior management can make decisions and the field team can course-correct. Deciding the cadence and format for progress-sharing in advance, and separating weekly field-level updates from monthly senior-management decisions, keeps reporting load down while preserving clear decision points.

• The cadence for progress-sharing (weekly, monthly, etc.) is decided
• A steering forum for senior management/decision-makers is set up
• A reporting format (progress, issues, pending decisions) is ready
• An escalation path for unexpected events is decided
• The scope of sharing with related departments (business, IT, legal) is organized

Step 7: Team structure

Purpose: organize the internal team that will run the PoC, and the division of responsibility if using outside support. A PoC needs more than technical verification — cooperation across business, IT, and legal. Organizing internal roles, and the responsibility split with any external partner, at the sign-off stage helps avoid stalling once work begins.

• The PoC's lead department and owner are decided
• The business, IT, and legal points of contact are each identified
• The internal staffing (people, time) available is roughly understood
• The responsibility split with an external partner, if used, is organized
• The decision-maker (who holds final authority) is clear

How to use the scoring sheet

Most items confirmed at each step

Ready to proceed to sign-off — proceed, noting any unconfirmed items as a risk.

Some steps still unorganized

The main issues are covered — recommend organizing the remaining items before drafting the request.

Multiple steps not yet started

Recommend organizing purpose, structure, and budget category first.

Talk to Netsujo

If "I can't quite finish organizing the sign-off points" or "I want advice on integration with existing systems, or how to structure staged budgeting," a free 30-minute first consultation can help work through the issues together — from as early as the stage of organizing verification scope and decision criteria for an internal approval. Our standard scope of support includes:

• Putting the purpose and problem into words, and narrowing the hypothesis to test
• Confirming the scope of integration with existing systems, and mapping out the path to production
• Designing staged budgeting and go/no-go criteria
• Designing steering and progress-sharing
