Engagement model matters as much as the vendor
Beyond picking the right software house, the engagement model you agree to - fixed-price, time-and-materials, or a dedicated team - genuinely shapes how the project unfolds, and each fits a different kind of project well.
This guide compares the three honestly rather than defaulting to whichever a vendor prefers to sell.
Why the wrong engagement model causes friction regardless of vendor quality
A fixed-price contract on a project with genuinely unclear requirements invites scope disputes; a dedicated team model on a small, well-defined project adds overhead it doesn't need - the model should match the project's actual certainty level.
We help clients pick based on how well-defined their requirements genuinely are, not vendor preference.
What's included
- Fixed-price - best fit when requirements are genuinely well-defined upfront
- Time-and-materials - better fit when scope will likely evolve as you learn
- Dedicated team - suited to ongoing, multi-month product development
- How team seniority mix is typically structured under each model
Our process
1. Assess how well-defined your requirements are
This, more than budget, should drive the engagement model choice.
2. Match the model to that reality
Fixed-price, time-and-materials, or dedicated team gets chosen based on genuine scope certainty.
3. Confirm team structure upfront
Who actually works on the project, and their seniority mix, should be clear before starting.
