Why estimates go wrong

The main reason is requirement uncertainty. The earlier you ask for a price, the wider the cone of uncertainty.

What an estimate consists of

  • Discovery and architecture — 10–15%
  • Design — 10–20%
  • Development — 50–60%
  • QA — 10–15%
  • Management and DevOps — 10%

Fixed price or T&M?

Fixed price suits small projects with clear requirements. For products that will keep evolving, Time & Materials with a per-sprint budget cap is fairer.
