Methodology

DDT: Discovery, Design & Technology

DDT is our pre-code phase: workshops where we align business goals, UX, architecture, and integration risks. Only then can we propose fixed pricing with a budget guarantee.

Why DDT at all?

Without a shared scope freeze, agencies either price in large risk buffers or push uncertainty back to you via time and materials. DDT turns ambiguity into a documented plan: specs, clickable mocks, and technical decisions.

Discovery

Stakeholder workshops, process maps, MVP priorities, and legal or operational risks. We know what to build and why.

Design

User flows, screens, clickable Figma prototypes, iOS/Android consistency. We treat design as product engineering, not decoration.

Technology

Stack choices (e.g. React Native, NestJS, MedusaJS), ERP/WMS/PIM integrations, non-functional requirements, and a delivery plan.

What you get after DDT?

  • A specification and backlog readable for both business and engineering
  • UX decisions and mocks as the single source of truth before build
  • Legacy integration risks assessed with a phased approach proposal

DDT questions

What is DDT at GMI Software?

DDT (Discovery, Design & Technology) is our structured pre-code phase: stakeholder workshops, MVP clarification, UX prototypes in Figma, plus architecture and integration decisions. That makes the product scope stable enough for a fixed-price quote.

How long does the DDT phase take?

Usually a few weeks, depending on product scale and how many systems we integrate. At the end of DDT you have specs, prototypes, and a technical plan - not just high-level assumptions.

Do we always sign a fixed-price agreement after DDT?

It is our preferred model for digital products: after DDT we prepare a fixed-price quote for the agreed scope. If new requirements appear after DDT, we treat them as a separate, explicitly scoped change.

Fixed price after DDT

Once DDT is complete, the scope is precise enough for a fixed-price implementation quote. It is our default model for product work: you know delivery cost before we sign the development agreement.

We also run UX/UI workshops, prototyping, and product discovery under Product Design.
