This document elaborates the three-tier purpose architecture for the NAVV Wiki product — specifying how the Wiki simultaneously serves NAVV's internal decision-making (Tier 1), the NDIS Handbook production pipeline (Tier 2), and future sector practitioners as a public information resource (Tier 3). It defines beneficiary statements, value exchanges, core hypotheses, probe designs, and done criteria for each tier, establishing the Wiki as a unified infrastructure supporting three distinct value transfers rather than a single product with multiple uses.

This is the Stage 3 enriched version of the Product Brief for the NDIS Wiki, developed through iterative analysis of market requirements and product scope. It was created to capture the evolved product understanding as the NDIS-Wiki concept matured. The brief serves as the specification for the NDIS Wiki product deliverable.

This document represents a point-in-time analysis. Subsequent decisions or implementation changes may supersede specific recommendations or assessments contained herein.

Type: P3 Product Artefact — Stage 3 (draft, awaiting Brian review)
Source: Product Brief - NDIS Wiki stub + missive directive NAVV-2026-05-09 (three-purpose framing)
Sentinel authority: Andrew (Product pillar)
Date: 2026-05-09
Reference: P3 Minimum Viable Products
Status: Draft — awaiting Brian approval before Product Brief - NDIS Wiki stub is updated

The missive identifies three concurrent purposes, each with a distinct beneficiary and value proposition. These are not development stages — they are simultaneous design considerations that must be held together from the outset.

P3 implication: The Wiki is not one product with three uses — it is one infrastructure supporting three distinct value transfers. Each tier has its own Beneficiary Statement, Value Exchange, and Done Criteria. Governance must hold all three tiers simultaneously without collapsing them.

Tier 1 — NAVV Internal:
The NAVV team — Brian and Andrew — in their planning, governance, and product development work. Before the Wiki: NDIS knowledge is scattered across individual experience, informal sources, and ad hoc research; each planning session requires re-derivation of foundational knowledge. After: the Wiki is the single source of truth from which all planning, commissioning, and product work proceeds — "where we steer the ship."

Tier 2 — Handbook Pipeline:
Future NDIS Handbook users — practitioners, educators, sector bodies — who will benefit from a Handbook whose content is provenance-grounded, structurally consistent, and maintained without independent duplication. Before the Wiki: each Handbook section requires its own research and editorial pipeline, creating version drift and maintenance burden. After: all Handbook content is developed within the Wiki, governed by its quality pipeline, and published via its content architecture. The Handbook becomes a curated, maintained extension of a living resource.

Tier 3 — Sector Resource:
Broader NDIS sector practitioners — Support Coordinators, Plan Managers, Psychosocial Recovery Coaches, allied health practitioners — seeking reliable, current NDIS domain knowledge. Before: practitioners navigate fragmented, unofficial, and often contradictory sources (Facebook groups, word of mouth, outdated NDIA materials). After: a governed, publicly accessible, maintained knowledge base is available — trusted because it is traceable to legislative and pricing sources.

Classification: Instrument (T1), Theory (T2 and T3), Service-in-development (T3 future state).

Tier 1 — Instrument:
Transfers the operational capacity for NAVV to make knowledge-grounded decisions consistently, without re-deriving foundational NDIS domain knowledge in each session. The Wiki is the decision substrate — not just a reference but the active base from which planning, commissioning, and product development proceed.

Tier 2 — Theory (structured and flowing):
Transfers structured, governable NDIS knowledge into the Handbook product. The value is not only what the Wiki contains — it is the governance architecture that ensures Handbook content is traceable to sources, consistent across articles, and maintainable as legislation and pricing evolve. The flow is directional: all Handbook content is developed in the Wiki and exported through a managed publication pipeline.

Tier 3 — Theory evolving toward Service:
Transfers current, trusted NDIS knowledge to sector practitioners via publicly accessible content. The "Context as a Service" evolution takes this further — knowledge is not only browsable but queryable, making the Wiki an active information provisioning service rather than a static library.

Tier 1: If NAVV maintains a governed NDIS knowledge base as its internal source of truth, all downstream products will be more consistent, accurate, and maintainable than if each product manages its own knowledge independently. The test: every P3 product brief's Validity Marker should trace its domain knowledge back to the Wiki — not to ad hoc research.

Tier 2: If all Handbook content is developed and governed within the Wiki before publication, the resulting Handbook will maintain structural consistency and legislative currency without requiring parallel maintenance workflows. The test: when PAPL changes, a single Wiki update propagates to all affected Handbook sections — no separate editorial sweep required.

Tier 3: If a governed, publicly accessible NDIS knowledge resource exists, practitioners will adopt it as a preferred reference over fragmented informal sources. The test: practitioner-reported reduction in time spent finding reliable NDIS information; organic citation and referral.

Current probe: Provisional-status Wiki — approximately RS-01 through RS-10 ingested, covering Core Support categories, Support Coordination, PACE framework concepts, and price codes.

What each tier is testing:

T3 scope boundary: Public access is not yet enabled. T3 probe requires a content governance decision — what is safe to publish — before it can begin. This is a Brian-to-confirm prerequisite.

Tier 1: NAVV resolves any NDIS domain question from the Wiki without resorting to external sources during a planning session. Andrew confirms the Wiki is his first stop for checking domain knowledge in his practice.

Tier 2: At least one NDIS Handbook section is produced by flowing Wiki content through a publication export, without requiring independent research or editorial from scratch. The section is structurally consistent with other Handbook sections by inheritance, not manual alignment.

Tier 3: At minimum two practitioners external to NAVV report the Wiki is useful for real-world practice questions. The Wiki is publicly accessible (filtered to safe-to-publish content).

Future commitment implied by T3 scope: Public content must be filtered against a "safe to publish" standard — articles may contain NAVV-internal planning notes, speculative content, or in-progress work that should not be externally accessible. A content classification standard will be needed before T3 goes live. Recommend as a future Critical Commitment candidate.
