FSD-FRM-02 — Gate 2 Solution Design

FitSDTier 4draft

Gate 2 asks: is it ready to build? Refine the approved Gate 1 idea into a buildable, operable design. The design must state how each Service Acceptance Criterion (§5) will be met — those are proven later on FSD-FRM-03. The live copy is held in the team’s work-tracking system; this is the blank template.

Sketch the architecture and where it fits in the wider estate. Include a diagram, and show where security sits in it. Note any departures from the team’s design principles.

5. Service Acceptance Criteria — design approach

Section titled “5. Service Acceptance Criteria — design approach”

State how each criterion will be met. Each is proven later on FSD-FRM-03.

CriterionDesign approach
DocumentationWhich docs (HLD, runbook, recovery, user) and where they will live
Backup (tested)What is backed up, frequency, retention, location — and how a test restore will be proven
SecurityHardening, patch path (FSD-RR), vulnerability posture, any exceptions (FSD-SA)
AccessAccess model — roles, least privilege, grant/revoke, admin control, JML handling
AvailabilityExpected availability / SLO, capacity & scaling, DR considerations
Monitoring & alertingWhat is monitored, thresholds, where alerts route
Incident profileWhat counts as an incident for this service — triggers and severities — to register with the incident-management process
Supportability / handoverOperating & support model, runbook, training needed; how continuity is assured — cross-training / knowledge capture so the service isn’t reliant on one person
Cost / licensingExpected run-cost and licences

Decision

Keep proportionate: person-days by role/workstream and a short milestone list — not a full FTE/capacity model (only reach for that under genuine resource contention).

Sign-off authorises progression to delivery. Build and deployment changes are then raised through Change & Release (FSD-CH).
