NNGroup UX Maturity Model (6 Stages · 4 Factors · Living System Perspective)
9 curated pieces from Nielsen Norman Group's 2021 updated UX Maturity knowledge base. Three core axes: ① 6 Stages/Levels: Absent → Limited → Emergent → Structured → Integrated → User-Driven — each stage includes characteristics, visible signals, three typical patterns, and advancement actions, all consolidated into one master table plus per-stage core mindsets and counterexamples; the dividing line between Stage 5 (the target state most companies should strive for, where UX serves the business) and Stage 6 (where UX becomes the soul of the organization, business originates from user value, which very few companies reach and struggle to sustain) is "user-centered" vs "user-first". ② 4 Factors: Strategy (Vision / Planning & Prioritization / Budget), Culture (Awareness / Appreciation / Competency / Adaptability), Process (Methods / Collaboration / Consistency), Outcomes (Impact of Design / Measurement) — each subfactor contributes equally, and improvement requires coordinated evolution across all four factors. ③ Living System Not a Ladder: growth is non-linear, can regress, and depends on daily care rather than reaching milestones; five pitfalls of ladder thinking (chasing rankings / treating "having" as "integrating" / mistaking tools for maturity / assuming maturity is permanent / over-assessment) vs five practices of the living system view (using rhythm instead of milestones / accepting fluctuation / using the model for reflection rather than as a ranking tool / celebrating sustainability); four cases (regression after leadership change in the financial industry · stable appearance masking stagnation in the healthcare industry · excessive pursuit of upgrade scores in SaaS · bottom-up growth driven by one person initiating conversations without formal support in the logistics industry). Includes self-assessment methods (interviews and observation / analysis of documents and deliverables / cross-departmental questionnaires). Target readers = product managers, with in-line explanations of jargon, decision-oriented (when to use / how to choose / counterexamples).
