21 curated articles from Nielsen Norman Group's organization and design process subset, with the core thread being how UX teams turn strategy into executable work. ① UX Strategy: Three stages of complex application design (Understand/Explore/Materialize), CASTLE framework for work software evaluation (Cognitive load/Advanced feature usage/Satisfaction/Task efficiency/Learnability/Errors, addressing the failure of the HEART framework for mandatory enterprise software), Mood Board (4-5 keywords + visual collage to define visual direction). ② Roadmap: Roadmap vs project plan (strategic questions vs execution tasks), three layers of scope (product/domain/initiative), who builds it and when (annual planning is most common · 34% take over 1 week · monthly updates · three-column storytelling presentation), 5 prioritization methods (Impact-Effort Matrix/IDEO's Feasibility-Desirability-Viability/RICE/MoSCoW/Kano), Pareto 80/20 rule to focus on the critical 20%. ③ UX Maps: 7-8 steps for interactive maps in Figma, Asset Mapping (omnichannel consistency, low effort), journey map creation time (survey of 343 people · total 73.8h ≈ two weeks · research-first vs assumption-first, 62% are assumption-first · assumption-first does not save time), Skill Mapping (radar chart scored 1-5 to identify skill gaps and single points of failure). ④ Risk and Debt: 6-step design risk (risk = probability × impact · risk matrix · mitigation measures), 4-step UX Debt (acknowledge/track/communicate/repair · allocate story points each sprint), Track Breakage (data → finding → insight → recommendation value chain · RAS adoption rate formula = Adoption×0.5 + Fidelity×0.3 + Impact×0.2). ⑤ Retrospective: 4-step Retrospectives (what went well/what to improve/action plan · sailboat metaphor · psychological safety), 7 elements of Project Postmortems (right people 6-10/success criteria/psychological safety/root cause 5 Whys/actionable outputs/owner + deadline/2-3 page archive). ⑥ Stakeholders: Mendelow Power-Interest Matrix (manage closely/keep satisfied/keep informed/monitor + attitude dimension), Stakeholder Interviews (semi-structured · as early as possible · simple collation for ≤5 people, thematic analysis for >5 people), cross-research team collaboration (UX as the central data hub), RACI responsibility matrix, UX responsibilities in 5 Scrum events. Audience = product managers, terms explained in industry language, decision-oriented (when to use/how to choose/counterexamples).
