RAIDD = Risks, Assumptions, Issues, Dependencies, Decisions — the single log referenced throughout the Governance Model, Dashboard, and Steering Deck for the CWP-700 Composite Wing Panel Production Program, spanning Phase 1 (Qualification & First Article) and Phase 2 (Production Ramp & Steady-State). Realized risks and issues trace forward into the Lessons Learned register and, where quality-relevant, into the Material Review Board log.

Score = Likelihood × Impact, each rated 1–3 (Low/Medium/High), for a 1–9 scale. 1–3 low · 4–6 medium · 7–9 high. The Low/Medium/High pair shown next to each score is (Likelihood/Impact).
| ID | Risk | Score | Owner | Status | Response |
|---|---|---|---|---|---|
| R-01 | Composite prepreg material lead time (single qualified material source) could delay Phase 1 tooling qualification | 9 (High/High) | M. Osei | Watch | Dual-source qualification initiated for the primary prepreg material; see D-03 |
| R-02 | NDT (ultrasonic inspection) capacity may not scale with Phase 2 production rate, creating an inspection bottleneck | 6 (High/Medium) | L. Vance | Mitigated | Realized — see I-02; a second NDT technician was qualified rather than outsourcing (D-01) |
| R-03 | Production tooling qualification could slip, delaying the First Article Inspection date | 6 (Medium/High) | A. Whitfield | Mitigated | Realized — see I-01; a 3-week schedule buffer was accepted rather than compressing the FAI schedule (D-02) |
| R-04 | Customer (Meridian) source inspection availability for FAI witness could bottleneck the FAI gate | 4 (Medium/Medium) | C. Tyrrell | Monitoring | FAI witness date pre-coordinated with Meridian's source inspection team 30 days out; see DEP-01 |
| R-05 | Single-source fixture/tooling fabrication supplier could delay the handoff from Critical Design Review (CDR) sign-off into Phase 1 fabrication | 4 (Low/High) | A. Whitfield | Monitoring | Fabrication lead time confirmed at CDR; no qualified backup supplier identified yet — flagged for the next Governance review |
| R-06 | AS9100 QMS ownership is concentrated in a single individual (R. Kessler); an unplanned absence would stall MRB dispositions and FAI sign-off | 3 (Low/Medium) | C. Tyrrell | Mitigated | Quality Inspector B. Solis cross-trained as backup MRB voting member per the Governance Model's succession section |
| R-07 | Original 14-person Phase 2 estimate, sized for a single production shift and one NDT resource, was insufficient to run real steady-state two-shift throughput — realized as an actual planning gap, not just a hypothetical risk | 6 (Medium/High) | C. Tyrrell | Mitigated | Realized — see D-05; drove the Resource Plan correction to 25 people across two shifts, reflected in the Program Budget's $5,200,000 baseline |
Assumptions
Assumptions
| ID | Assumption | Owner |
|---|---|---|
| A-01 | Meridian's engineering source data (drawings, specs, tolerances) is final and baselined at contract start; no major spec changes during Phase 1 | C. Tyrrell |
| A-02 | Composite autoclave capacity at the Acme facility is sufficient for the planned Phase 2 production rate without additional capital investment | M. Osei |
| A-03 | Raw-material suppliers will deliver PPAP submissions on the agreed schedule without requiring a re-submission cycle | S. Pham |
| A-04 | Meridian will route any post-CDR engineering change through a formal contract modification rather than an informal design change | C. Tyrrell |
| A-05 | The 3 manufacturing technician rotations qualified during Phase 1 will remain available at planned allocation through the full Phase 2 production ramp | M. Osei |
Issues
Issue Log
| ID | Issue | Owner | Status | Resolution | Target / Actual Closure |
|---|---|---|---|---|---|
| I-01 | First Article dimensional nonconformance found on the initial tooling run (edge trim out of tolerance on 2 of 8 panel positions) | R. Kessler | Closed | Dispositioned via MRB as rework; reworked panels re-inspected and accepted (see Material Review Board log) | Closed, Phase 1 |
| I-02 | NDT queue backlog formed during early Phase 2 ramp, adding roughly 4 days to the panel release cycle time | L. Vance | Resolved | A second NDT technician was qualified and added to the rotation, per D-01; cycle time returned to plan within 2 weeks | Closed, Phase 2 |
| I-03 | A brief MRB backlog held 2 nonconforming panel sets in disposition-pending status for 3 days during peak Phase 2 volume | J. Ferraro (MRB Chair) | Closed | MRB added a standing weekly session (in addition to as-needed sessions) once Phase 2 volume made the ad-hoc cadence insufficient | Closed, Phase 2 |
| I-04 | FAI checklist wording was found ambiguous by the customer source-inspection auditor on 2 acceptance criteria, risking inconsistent future FAI results | R. Kessler | Resolved | FAI checklist (fai-checklist.xlsx) revised with unambiguous pass/fail criteria and re-issued for all subsequent article runs | Closed, Phase 1 |
| I-05 | A raw-material lot's PPAP submission arrived incomplete (missing one dimensional report), delaying that lot's qualification by 3 days | S. Pham | Closed | Complete submission received and re-reviewed; supplier notified of the completeness requirement ahead of future lots | Closed, Phase 2 |
Dependencies
Dependency Log
| ID | Dependency | Owner | Status |
|---|---|---|---|
| DEP-01 | Meridian source-inspection representative availability to witness the First Article Inspection | C. Tyrrell | Scheduled |
| DEP-02 | Raw-material supplier certifications (material certs, PPAP submissions) required before FAI can be scheduled | S. Pham | Received |
| DEP-03 | Phase 2 production rate ramp depends on the second NDT technician (D-01) completing qualification training | L. Vance | Complete |
| DEP-04 | The new quarterly PPAP review cadence (D-04) depends on suppliers submitting quality data on the agreed schedule | S. Pham | On Track |
| DEP-05 | Phase 1 fabrication cannot begin until Meridian engineering signs off at the Critical Design Review (CDR) gate | A. Whitfield | On Track |
Decisions
Decision Log
| ID | Decision | Decided By | Date |
|---|---|---|---|
| D-01 | Qualify a second NDT technician mid-Phase-2 rather than outsourcing ultrasonic inspection, to keep traceability in-house | R. Kessler | Feb 11, 2027 |
| D-02 | Accept a 3-week schedule buffer in Phase 1 for tooling qualification rather than compress the FAI schedule | C. Tyrrell | Oct 2, 2026 |
| D-03 | Approve dual-source qualification of the primary prepreg material rather than continuing single-source, given R-01's exposure | C. Tyrrell / Meridian Program Office | Nov 19, 2026 |
| D-04 | Establish a standing quarterly PPAP review cadence with key raw-material suppliers rather than an annual review, to catch quality drift earlier | R. Kessler | Jan 7, 2027 |
| D-05 | Correct the Resource Plan from a 14-person, single-shift estimate to a 25-person, two-shift team — adding a second layup shift, dedicated Autoclave/Cure and Trim & Drill Technicians, a second Level II NDT Technician, a Document Control Specialist, and an EHS & Facilities Coordinator (11 added positions, +$1,634,000 labor) | C. Tyrrell / G. Talmadge (VP Operations) | Sep 28, 2026 |
| D-06 | Meridian Aircraft Co. issued Purchase Order Amendment PA-002, increasing the CWP-700 monthly production rate — this is genuine customer-driven demand growth, not a staffing correction for the existing rate. Program expands from 25 to 50 people: a third production shift (layup, autoclave/cure, trim & drill, NDT, quality inspection — mirroring the existing Shift 1/2 structure), a Deputy Program Manager and second Manufacturing/Supplier Quality Engineers for the larger program, and new support functions the higher throughput requires that didn't exist at the lower rate (Materials Handling/Logistics, Maintenance Technicians, Incoming Material Inspection, Packaging/Shipping, a Production Scheduler, Training Coordinator, and IT/Systems Support). Budget grows from $5,200,000 to $9,284,000. | C. Tyrrell / G. Talmadge (VP Operations) | Jul 3, 2027 |
