Start with a brief, end with a structured scope

Most projects begin as a vague brief or client email. The challenge is turning that into a structured estimate with modules, tasks, and hours. This page walks through the complete process — from raw input to a reviewable, client-ready scope.

Break features into tasks before estimating hours

Estimating "build a dashboard" is guessing. Estimating "create chart component, connect API, add filters, write tests" is planning. devtimate enforces a module → task hierarchy so every hour estimate has a clear task behind it.

Assign roles to know who does what

Each task needs a role — frontend, backend, QA, DevOps. Without role assignment, you cannot calculate costs or plan team capacity. devtimate assigns roles per task so you see the full team picture before quoting.

Use min-max ranges to handle uncertainty honestly

A single-number estimate is a promise you cannot keep. Min-max hour ranges per task acknowledge real-world uncertainty. devtimate rolls these up into project-level ranges so clients see realistic timelines, not optimistic guesses.

The estimation process
step by step

Step 1: Gather and upload inputs

Collect everything the client sent — RFP, feature list, email thread, meeting notes. Upload it all into devtimate. AI reads every document and extracts features, integrations, and constraints. You can also type a brief manually.

Step 2: Generate the scope
with AI or build manually

Let AI create the first draft — modules, tasks, roles, and hours — or build the structure yourself with drag-and-drop. Most teams use AI for the first pass and then adjust. The result is the same: a hierarchical scope with every task accounted for.

Step 3: Review, adjust, and get team input

This is where your expertise matters. Review every task, adjust hours based on your experience, and use the AI Agent to make bulk changes fast.

Senior engineers validate the scope. Junior PMs learn from the structured output. Everyone works from the same baseline.

Bulk edits with AI Agent

Type "increase QA hours by 20%" and every QA task updates. No manual cell editing.

Approve each change

See what AI proposes before applying. Accept, reject, or modify individual suggestions.

Step 3: Review, adjust, and get team input

Step 4: Price, propose, and deliver

Apply your rate card to calculate costs. Generate a branded PDF proposal. Export tasks to Jira, Asana, or Excel to start delivery.

The estimate flows from scope → price → proposal → project plan without re-entering data.

Without a process
estimates are just guesses

Most teams skip the process and just guess

Without a clear process, estimation becomes "I think this is about 200 hours." No task breakdown, no role assignment, no documented assumptions. The estimate lives in someone's head — and falls apart the moment the client asks "what's included?"

Good estimates need structure, not just experience

Experience helps, but it is not a process. A structured workflow — break down → assign roles → estimate hours → review → price — produces estimates that are explainable, repeatable, and defensible. devtimate enforces this structure.

A repeatable process scales with your team

When the process is defined, anyone on the team can start an estimate. AI handles the first draft. Seniors review instead of building from scratch. New hires learn by seeing how estimates are structured. The quality stays consistent as the team grows.

FAQ about the
estimation process

Break the project into modules and tasks, assign a role to each task, estimate min-max hours per task, then roll up to a project total. This bottom-up approach is more accurate than top-down guessing because every number has a task behind it.

Tasks should be small enough to estimate confidently — usually 2–40 hours each. "Build dashboard" is too big. "Create chart component," "Connect data API," "Add date filters" are estimable. devtimate enforces this module → task hierarchy.

Use AI for the first draft — it is faster and catches tasks you might miss (testing, deployment, documentation). Then review manually. The best estimates combine AI speed with human judgment.

Document your assumptions explicitly. If the brief says "user management," assume standard scope (login, registration, roles, profiles) and note it. Min-max ranges handle the uncertainty. Share assumptions with the client to align expectations early.

Include every role that will work on the project — frontend, backend, QA, DevOps, designer, PM. Forgetting QA or DevOps is one of the most common estimation mistakes. devtimate prompts you to assign roles per task so nothing gets missed.

The task breakdown works for both. For agile, tasks map to user stories and export to Jira/Asana for sprint planning. For waterfall, group tasks into phases. devtimate supports both — the estimation structure is the same, only the delivery approach differs.

Use AI to create the first draft without pulling engineers. Then have seniors review for 15–30 minutes to catch edge cases and adjust hours. This saves 80% of engineering time compared to building the estimate from scratch.
