Twelve Weeks. Eight to Twelve Peers. One Sponsor-Facing Artefact.
The Halo cohort is the highest-leverage format in the AI Fluency programme. Senior leaders work across twelve weeks of weekly 90-minute sessions, building nine concrete artefacts that close into one deliverable — a sponsor-facing 90-Day AI Adoption Plan that authorises the next ninety days of action.

90-Day Plan
Nine Concrete Artefacts. Sponsor-Facing. Not Theoretical.
Every Halo participant leaves with operational deliverables, not certificates. Each artefact is reviewed by your facilitator and re-rated through the cohort. The final 90-Day Plan integrates all nine.
Personal AI Audit
70/20/10 baseline + six-month target. Re-rated at Weeks 4, 8, 12. The diagnostic that defeats self-flattering claims about fluency.
Five Bias Types Audit
Per-type score on one named deployment in your firm. Audit cadence committed. The taxonomy that produces five distinct interventions.
AQO Decision Log
48-hour decision log. Two failure modes assessed. The visibility principle made institutional.
Architecture Application Log
All three architectures (Scaffold, Output Template, Iterative Refinement) run on real prompts from your week.
Trust Curve Placement
Three deployments placed on the Trust Curve. Progression Plan written for one. The compounding case for patience.
Cultural Profile
Dominant pattern + sub-patterns. Calibrated Change-Plan. Bilateral Plan if your operation crosses borders.
Workflow Map + Redesign Plan
One real workflow mapped honestly. Identified for High / Medium / Low. Redesigned across the four moves.
88/5 Closure Diagnosis
Your firm’s dominant cause + 1-2 secondary. Closure framework callbacks named. The structural reading.
90-Day AI Adoption Plan
Sponsor-facing. Six elements. The artefact that authorises the next ninety days — and the conversation you take to your sponsor.
The 90-Day Plan is the artefact that authorises the next ninety days. Without it, AI adoption inside the firm stays anecdotal. With it, the next sponsor conversation is short and concrete.

Which Closure Needs Which Sponsor. Mismatch Is the Top Failure Mode.
Each closure mechanism requires a different sponsor authority. Halo helps you find the right named individual before the 90-Day Plan is written — because the plan that names the wrong sponsor stalls regardless of how well it is structured.
| Closure Framework | Sponsor Authority Required | Time Horizon |
|---|---|---|
| F7 · Deployment without redesign | COO or function head · budget + cross-functional power | 30–90 days |
| F5 · Trust-curve stall | CEO or division head · risk appetite for Phase transitions | 6–18 months |
| F6 · Cultural-pattern mismatch | Group HR / CHRO · cross-geography authority | 9–24 months |
| F2 · Governance debt | CRO / Chief Compliance · regulatory liaison + audit | Continuous cadence |
| All four · cross-cutting | CFO · value-capture mechanism · without CFO, value stays anecdotal | Quarterly review |
The Research Underwriting Halo.
The eight frameworks emerged from longitudinal qualitative work across 23 firms in APAC, EU, and NA over 2023–2025. Composite cases throughout. Public-facing attribution by sector and theme only.
How the Frameworks Were Built
Each framework was tested against composite case material before canonical formalisation. The 88/5 gap framework synthesises external research with internal cohort diagnostics. All firm-specific data is anonymised; cases are composite illustrations.
Halo participants receive the canonical research alongside the practitioner application — both the public research paper and the longer ebook are included in the programme materials.
