Sayah ConsultingLet’s talk
Product development

From idea to launch.
Every step defined.

Requirements, statement of work, high-level and low-level design, development, testing, security and deployment, or a rebuild of what you already have.

Product development, end to end

From idea to launch.
Every step defined.

Many projects stall because the requirements are thin, the scope is vague and the designs are generic. We do the groundwork properly, then build, test, secure and launch, keeping you updated at every step.

  1. 1

    Discover

    • Requirements gathering No business analyst? We provide one and write the requirements with your team.
    • Detailed statement of work Scope, deliverables, milestones and acceptance criteria, so nothing is left open.
  2. 2

    Design

    • UX and prototype Screens your users can try before anything is built.
    • High-level design Architecture drawn for your product, not generic diagrams.
    • Low-level design Every interface, data field and rule specified, so delivery is not delayed.
  3. 3

    Build

    • Agile delivery Sprint plans, progress you can see each week and shippable releases.
    • Development AI-assisted, with every change reviewed by an engineer.
    • Documents and runbooks Written as we build, not at the end.
  4. 4

    Test

    • Functional and end-to-end testing Every journey, every release.
    • Performance, load and stress Proof it holds up at peak.
    • Non-functional Accessibility, usability, compatibility and UK GDPR checks.
  5. 5

    Secure

    • Vulnerability and penetration testing Weaknesses found and fixed before launch.
    • Threat protection Web application firewall, data protection and privileged access.
  6. 6

    Launch and support

    • Deployment Automated release with a tested rollback plan.
    • Data migration Existing data moved and checked.
    • Training and handover Your team knows how to run it.
