Phase 1 – Discovery and requirements
Goals, users and compliance drivers are captured in workshops and written backlogs. Without a shared definition of success, scope creeps and budgets slip. We prioritise outcomes (e.g. reduce ticket handling time by 30%) and map them to measurable acceptance criteria before estimating effort.
Phase 2 – Architecture and technical design
Stack choices, integration points, hosting model and security controls are decided explicitly. Architecture decision records help future developers understand trade-offs. Early spikes validate risky assumptions – performance of a specific query pattern, device firmware handshake or third-party API limits.
Phase 3 – UX/UI and prototyping
Wireframes and clickable prototypes surface misunderstandings cheaply. Accessibility, localisation and responsive layouts are considered before engineering commits to components. Feedback loops with real users (even five sessions) often prevent expensive rework after sprint three.
Phase 4 – Iterative implementation
Short cycles with demonstrable increments keep sponsors engaged. Automated tests guard core flows; feature flags allow safe rollout. Continuous integration catches integration issues early, especially when multiple services or mobile clients consume the same API.
Phase 5 – Quality assurance and hardening
Beyond functional tests we look at load scenarios, backup/restore drills and security basics (dependency scanning, OWASP-style checks). Documentation for operators – runbooks, environment variables, on-call expectations – closes the gap between developers and IT operations.
Phase 6 – Go-live and migration
Cutover plans include rollback paths, communication templates for users and monitoring dashboards. Data migration scripts are idempotent and verified against checksums. Hypercare windows stabilise the first production weeks before handing off to steady-state maintenance.
Phase 7 – Maintenance and evolution
Roadmap items, incident reviews and technical debt budgets keep the product healthy. Regular dependency updates and licence compliance scans prevent surprises. We align enhancement backlog with business KPIs so every release ties to measurable value.
