# ADR 2026 05 21 **File:** ADR-2026-05-21.md\ **Author:** Nicolette Martine Langendam — NikiDigitals\ **Location:** LES-Master/docs/decisions/\ **Decisions covered:** ADR-000107 through ADR-000109\ **Session type:** LES-MENTOR — Phase 0 Close, Portfolio Publication, GitBook Review ## Context This file records all decisions made on 21 May 2026. The session completed the final actions required to formally close Phase 0, established the documentation review process for GitBook, and defined the publication architecture for Phase 0 milestone content across all portfolio layers. ## Operational Decisions ### ADR-000107 — LES-DOCS-REVIEW-001 Established — GitBook Review Task List **Decision:** A structured GitBook review task list — LES-DOCS-REVIEW-001 — is established as a formal document and stored in `LES-Master/docs/reviews/`. A dedicated `reviews/` folder is created within LES-Master/docs/ to house review task lists, quality checks, and audit logs. **Context:** A section-by-section review of the GitBook space was conducted on 21 May 2026, identifying gaps, empty pages, placement issues, duplicate risks, and content requiring update. Rather than attempting to resolve all items in the same session, they were captured in a structured task document for a dedicated LES-DOCS session. **Contents of LES-DOCS-REVIEW-001:** The review identified the following categories of work: * Missing content — empty pages requiring content before GitBook is suitable for public visitors * Placement decisions — sections or pages whose location in the navigation may need revision * Naming decisions — section headings that could be more specific or consistent * Structural decisions — pages that may be redundant given content elsewhere in the space * Template requirements — standard page formats needed for recurring content types **Standing review criteria established:** * Check for duplicate content across sections * Check for unclear or ambiguous section headings * Check overall navigation logic — does the structure make sense to a first-time reader **Rationale:** A live GitBook space is a public-facing document. Allowing empty pages, inconsistent headings, or structural ambiguity to persist before directing LinkedIn connections to the space would undermine the credibility of the portfolio. The review task list ensures gaps are tracked and resolved systematically rather than informally. **Consequences:** `LES-Master/docs/reviews/` folder created. LES-DOCS-REVIEW-001.md committed. LES-DOCS session scheduled for Week 4 to work through the task list. GitBook readiness review required before LinkedIn posts are published. ### ADR-000108 — Milestones Sub-Page Added to Website **Decision:** A Milestones page is created on nikidigitals.com as a sub-page under LES — The Project, accessible via a dropdown submenu in the main navigation. **Navigation structure:** ``` LES — The Project ▾ └── Milestones ``` **Context:** Phase 0 completion constituted the first significant project milestone. The website required a dedicated location to record phase completions, certifications earned, and major build deliverables over the five-year programme. A standalone top-level page was considered but rejected as premature — a submenu item under the project page is the correct level at this stage. **Content at launch:** * Phase 0 — Foundation & Environment — ✅ Complete — May 2026 * Phase 1 — Data Architecture — 🟢 In Progress — target June 2027 * Phases 2–5 — future phases listed as placeholders **Rationale:** A Milestones page provides a scannable timeline for the executive audience — the same audience that visits the website and needs a quick-read summary of project progress without technical depth. The submenu placement keeps the main navigation clean while making the milestone history findable. As phases are completed, certifications earned, and modules built, this page grows into a credible evidence trail. **Consequences:** Milestones page live at nikidigitals.com. Sub-menu under LES — The Project confirmed. LES — The Project page updated with a link pointing to Milestones. Page to be updated at each phase completion and significant milestone. ### ADR-000109 — Phase 0 Retrospective Published — Three-Layer Publication **Decision:** The Phase 0 retrospective is published across three portfolio layers in three distinct formats, each calibrated for its audience. **Publication record:** | Version | Platform | File | Audience | Status | | ------------------ | --------------------------- | ---------------------------- | ------------------------------- | ------------------------ | | Full retrospective | GitBook — The Journey | LES-RETRO-000001-gitbook.md | Technical and academic | ✅ Published | | Executive summary | Website — Milestones | LES-RETRO-000001-website.md | Executive — C-suite, recruiters | ✅ Published | | LinkedIn post | LinkedIn — Personal profile | LES-RETRO-000001-linkedin.md | Professional network | ⏳ Pending GitBook review | **Document code established:** `LES-RETRO-000[NNN]` — phase retrospectives. Added to document taxonomy. **LinkedIn publication sequence:** 1. Post 1 — Project introduction — to be written 2. Post 2 — Phase 0 milestone — draft complete — publish after introduction post 3. Repost both from NikiDigitals company page immediately after **LinkedIn publication gate:** GitBook readiness review must be passed before any LinkedIn post is published. The posts direct readers to GitBook — the space must be ready to receive them. **Context:** Phase 0 completion represents the first significant public milestone of the LES project. The three-layer publication architecture ensures that every portfolio audience receives the appropriate level of detail — full academic rigour on GitBook, executive summary on the website, concise professional signal on LinkedIn. **Rationale:** A Finance Transformation Architect builds and documents in public from the beginning — not only after the work is finished. Phase 0 established the foundation. Publishing its completion publicly signals that the project is real, disciplined, and professionally executed. The three-layer approach ensures no single audience receives content calibrated for a different one. **Consequences:** LES-RETRO-000\[NNN] added to document taxonomy. GitBook retrospective live. Website Milestones page live. LinkedIn posts drafted and ready. Publication pending GitBook readiness review. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
