Over my years leading UI/UX work — including as a Senior UI/UX Engineer in R&D at Arçelik, one of the largest manufacturers in its sector — I developed a comprehensive playbook for designing and delivering great digital products. It was originally created as the Arçelik DigITal UI/UX Playbook: a single, structured framework that any team could follow to put the user at the centre of everything they build. This series is that playbook, refined and shared publicly.
This is the overview. The playbook is organised into five parts, each a complete guide in its own right, and each linked below. Together they form an end-to-end methodology — from the philosophy of user-centred design, through strategy and interface craft, to team governance and the practical deliverables that bring it all to life.
Why a Playbook?
Building a successful digital product — whether a fully responsive website or a mobile application — rests on a single principle: user first. The user sits at the very centre of the product lifecycle, and everything else is shaped around them. This isn’t a project that ends once a build is delivered; it’s a Design Thinking-driven mindset operating in the endless lifecycle of evolving user needs.
The challenge most teams face isn’t a lack of individual skill — it’s the absence of a shared, structured approach that aligns strategy, design, engineering, and testing around the user. A playbook solves that. It gives a diverse, cross-disciplinary team a common language and a common method, so that everyone from strategists to front-end developers is pulling in the same direction.
The Four Focus Areas of Great UX
A great user experience has to create value for users — and even a great UX must be tested, strengthened over time, and kept flexible. The playbook organises this work into four focus areas, which map directly onto the five parts of this series:
- UX Strategy — the activities carried out to understand and validate users and their needs.
- UI Tactics — the design approaches and trends used to build and craft the user interface.
- UX Governance — how teams of people with different skills and specialisms work together to produce the best experience.
- UX Tools, Technologies & Deliverables — the communication tools, technologies, and the outputs produced from their analysis.
All four rest on a foundation of core UX principles — which is where the playbook begins.
The Five Parts of the Playbook
Part 1 — UX Principles & Foundations
The philosophy underneath everything: what UX, UI, usability, and interaction actually mean and how they relate; the eight foundational principles (from prioritising UX and minimising risk to modular, device-independent design); and the Think–Make–Check model for building a successful experience. Read Part 1 →
Part 2 — UX Strategy
Turning user understanding into a plan: the components of a UX strategy (vision, KPIs, plan); defining your MVP; understanding users through qualitative and quantitative research; content strategy; and usability testing methods. Read Part 2 →
Part 3 — UI Tactics
The craft of the interface: Nielsen’s heuristic principles, accessibility design, the 12-column grid system, mobile-first responsive design, the “fat finger” touch-target rules, and the atomic design system methodology. Read Part 3 →
Part 4 — UX Governance
How teams work together: Waterfall versus Agile approaches, managing failure risk, the transition from Waterfall to Agile, user story maps, and sprinting with backlogs. Read Part 4 →
Part 5 — UX Tools, Technologies & Deliverables
The complete toolkit: personas, user journey maps, user story maps, user flows and DoGo maps, taxonomy design, storyboards, wireframes, design mockups, design systems, and prototypes. Read Part 5 →
How to Use This Playbook
The five parts are designed to be read in sequence — each builds on the last — but each also stands alone as a reference for its specific area. If you’re building a product from scratch, start at Part 1 and work through. If you’re solving a specific problem — say, structuring an Agile team or choosing the right deliverable — jump straight to the relevant part.
This playbook reflects how I think about UI/UX architecture, and it connects closely to other work on this site, including what a UI/UX Architect actually does and building a scalable design system.
This playbook was developed and authored by Gökhan Meriç, originally as the Arçelik DigITal UI/UX Playbook. Want to discuss applying it to your team or product? Get in touch.
