Buyers often “accept” software after a demo theatre week and then discover missing evidence when production hurts. An acceptance test evidence pack is the set of artefacts that prove the system met agreed criteria under realistic conditions. This checklist helps Singapore and Philippines buyers demand the right pack before go-live—complementing WC1’s custom software UAT checklist with a focus on evidence, not only test ideas.

What belongs in an acceptance evidence pack

Signed scope and acceptance criteria baseline (or controlled change log).
Traceability matrix from requirements or user stories to test cases.
Executed test results with timestamps, environments, and tester identities.
Defect list with severities, workarounds, and deferred items accepted in writing.
Non-functional test evidence: performance, security scans, accessibility if in scope.
Integration contract test results for critical interfaces.
Data migration reconciliation reports if migration is in scope.
Rollback or remediation drill evidence.
Training completion or readiness confirmation for named operator groups.
Open risk list with risk acceptances by accountable owners.

Environments and data realism

Evidence from a toy environment with synthetic happy-path data is weak. Require a statement of how close the acceptance environment is to production in configuration, volumes, and integrations. If production-like data is restricted, document masking approaches and residual gaps. Do not accept “it worked on my machine” screenshots as the pack.

Roles: who produces and who accepts

Vendor or build team produces raw execution evidence.
Client business owners accept functional fitness for purpose.
Client IT/ops accept operability, monitoring, and access hygiene.
Security accepts residual vulnerability posture when in scope.
A single client acceptance lead consolidates sign-off—avoid scattered emails.

Minimum evidence for go-live gate

You can phase evidence, but go-live should not proceed with empty critical sections. At minimum: critical journey tests passed, Sev-1/2 defects closed or formally accepted, integration checks green for money/movement/identity paths, monitoring and rollback story evidenced, and access reviews done for production. Tie this to hypercare exit planning so acceptance is not a one-day ceremony.

Anti-patterns

Accepting based on a vendor-run demo without client-executed cases.
Missing traceability so nobody knows what was untested.
Deferring all non-functionals to “after go-live.”
Oral acceptances with no artefact archive.
Changing scope silently during UAT without updating criteria.

Contract language buyers can request

State that acceptance requires delivery of the evidence pack sections listed in a schedule, that sign-off is written, and that go-live is gated on acceptance or explicit risk waiver. Link warranty start to acceptance where appropriate. Keep the schedule practical—overstuffed packs become theatre too.

APAC operating tip

With Singapore sponsors and Philippines delivery, store the pack in a shared controlled repository and run a joint walkthrough in overlap hours. Timezone-only email chains lose defects. Connect acceptance to hypercare week one and exit criteria so the programme does not celebrate early.

Implementation notes for busy teams

Checklists fail when they stay in slide decks. Put each item into a tracker with owner, due date, and evidence link. Review weekly until closed. If an item cannot be evidenced, treat it as open risk—not as “mostly done.” Across Singapore sponsors and Philippines delivery, keep overlap hours sacred for decisions that otherwise stall for a day.

Create a shared folder with read access for sponsors and write access for operators.
Require artefact links in the tracker—no closed status without evidence.
Escalate blockers older than five business days to the steering forum.
Keep Singapore and Philippines owners visible on every critical row.
Archive decisions with date and rationale so future teams inherit context.
Rehearse the top failure mode once before you scale traffic or headcount.

What “good enough” looks like before you proceed

Perfection is not the bar. Proceed when residual risks are named, owners exist, and compensating controls are written. Do not proceed when critical access, data, or rollback questions remain unanswered. Write the difference down so the organisation shares the same meaning of ready. Sponsors should hear residual risk in plain language—not buried in a RAID log nobody opens.

Critical path owners named and reachable in the next incident window.
Data and access questions answered with diagrams or configs, not slogans.
Rollback or remediation path exists for the top failure modes.
Commercial schedules match the operating model you just agreed.
A follow-up date is booked before anyone declares victory.
Support and communications know what changed for customers or staff.

Steering questions to close residual gaps

Use these questions in the next steering session to force clarity. If answers are vague, keep the item open. Singapore sponsors and Philippines delivery leads should answer together so timezone handoffs do not become excuses for missing ownership.

What evidence would falsify our current plan within two weeks?
Which residual risks are we explicitly accepting, and who signs acceptance?
What breaks if a critical person is unavailable for ten business days?
Where do decision rights sit when product, security, and vendor disagree?
What does done look like in artefacts, not adjectives?
What is the customer or employee impact if we slip one more cycle?

Thirty-day action rhythm

Days 1–7: gather artefacts and name owners. Days 8–14: close critical evidence gaps and write residual risks. Days 15–21: run one rehearsal or tabletop for the top failure mode. Days 22–30: present a go, conditional go, or no-go recommendation with written acceptances. Keep the rhythm visible on a single page so executives do not need a separate translation layer.
