SCOPE

Agree the outcome before work starts.

Separate the core version from optional features. A small, testable first version makes it easier to identify a rule misunderstanding before adding more complexity.

A working implementation is a software deliverable. Profitability and future market performance are not acceptance criteria we can promise.

YOUR PROJECT

A clear handoff on both sides.

What to prepare

Written entry, exit, sizing or display rules

Worked examples and what should happen in edge cases

Required inputs, target platform and delivery preference

What to agree in the quote

An agreed feature list and usable program

Source code when included in the scope

Usage notes and test scenarios
