The three models look similar in a proposal. They behave very differently in a sprint, and the difference shows up in one place: how much of your senior engineers' week each one consumes. If you are choosing because you have no capacity, that is the comparison that decides it.
Day rates are close enough across the three that they rarely settle the question. Supervision cost is not close at all.
Key takeaways
- Staff augmentation buys hands, and spends attention: Someone internal has to direct and review.
- A dedicated team buys a team, and still needs a product owner: Usually yours.
- A product partner buys an outcome: You review working software instead of directing work.
- Pick by what you are short of: Hands, structure, or attention.
Staff augmentation
Individual engineers join your team. They use your repository, your process, your standups, and follow your technical direction.
What you get: flexible headcount, quickly, with the ability to scale up and down. Your standards and architecture apply because the work happens inside your setup.
What it costs: direction. Every person needs onboarding, code review, architectural guidance and someone to answer questions. That comes from your senior engineers, which is the resource you were short of.
When it works: you have capacity to direct but not enough hands. A well-defined backlog, a tech lead with room in their week, and work that is understood.
When it fails: your bottleneck is senior attention. Adding people to a team with no review capacity slows the team down, and this is the most common expensive mistake in this whole area.
Dedicated team
A team assembled for you, working only on your work, usually from one supplier. They bring their own internal structure and often a lead.
What you get: less per-person overhead than augmentation, because the team coordinates itself. Continuity, and people who accumulate knowledge of your domain.
What it costs: product direction still has to come from somewhere. Most dedicated team arrangements assume you supply the product owner, the priorities and the acceptance decisions. If you do not have someone with time for that, the team will build competently in a direction nobody has chosen.
When it works: you have a clear product direction and a person to hold it, and you need durable capacity rather than a burst.
When it fails: it is sold as turnkey but staffed as augmentation. Ask specifically who decides what gets built when you are not in the room.
Product partner
An external team takes a product rather than a seat: scoping, building, running it on its own surface, with its own on-call. You set direction and priorities, and review working software on a cycle.
What you get: the outcome, and your engineers' time back. Delivery risk sits with the supplier rather than with your ability to manage them.
What it costs: less day-to-day control, and a genuine dependency on the partner's judgement. It also requires the new product to be separable from your existing system, which is not always true.
When it works: a distinct new product, a boundary that can be drawn, and no spare senior attention internally.
When it fails: the work is really an extension of your core system and cannot be separated. Then you are paying partner prices for something that needs to be inside your codebase.
Side by side
| Staff augmentation | Dedicated team | Product partner | |
|---|---|---|---|
| You supply | Direction, review, architecture | Product ownership, priorities | Priorities and decisions |
| Your senior team's load | High, continuous | Medium | Low after week one |
| Delivery risk sits with | You | Shared | Them |
| Best when short of | Hands | Structure | Attention |
| Hardest part | Review capacity | Product ownership | Drawing the boundary |
The question that settles it
Ask: who decides what gets built next week, and who notices if it is wrong?
If the answer is someone inside your company who already has a full week, augmentation and dedicated teams will both underperform, regardless of how good the engineers are. If you have someone with real capacity to own the product day to day, the cheaper models become viable.
For the broader set of options including hiring, see what to do when your engineering team has no capacity.
