These three terms get used as if they were interchangeable. They are not, and most bad experiences come from buying one while expecting another. The difference comes down to two questions: who decides what gets built each day, and who is accountable for the result.
The three models in one line each
- Staff augmentation. Engineers join your team and you manage them.
- Project outsourcing. A vendor delivers a defined scope for an agreed price.
- A dedicated team. A vendor provides a standing team that works only on your product and manages its own delivery.
Side by side
| Staff augmentation | Project outsourcing | Dedicated team | |
|---|---|---|---|
| Who sets daily priorities | You | The vendor, against the agreed scope | You set priorities; the team lead runs delivery |
| Who answers for the outcome | You | The vendor | Shared: the vendor for delivery, you for direction |
| How it is priced | Time and materials, per engineer | Fixed price or milestones | Time and materials, per team |
| What you need in-house | Engineering leadership and a clear backlog | A stable specification and someone to accept the work | A product owner who can make decisions |
| Works best when | You have the leadership and need more senior capacity | The scope is clear and unlikely to change | The product is long-lived and priorities move |
| Main risk | Engineers without direction | Scope changes turning into disputes | Drift, if nobody on your side owns the roadmap |
How to choose
- If you have engineering leads and a backlog but not enough hands, choose staff augmentation.
- If you can write down exactly what you need and it will not change, choose a fixed-scope project.
- If you are building a product that will evolve for years, choose a dedicated team.
Many companies move between models. A fixed-scope first release often becomes a dedicated team once the product is live.
The question that matters in all three
Whichever model you pick, the result depends on who the engineers are and whether they stay. Ask for the retention rate, and ask to meet the people. The twelve questions to ask an offshore team apply to all three.
Where TechMaven fits
We work in all three ways: fixed-scope projects for clearly bounded builds, time-and-materials dedicated teams for ongoing product work, and staff augmentation for teams that want senior engineers under their own direction. Most long-term clients begin with a four-to-eight-week paid pilot.
