Staff augmentation costs the day rate plus the hours your own senior engineers spend directing, reviewing and onboarding the people you add. The rate appears on an invoice. The hours do not. Work out both before you compare augmentation with a dedicated pod or a delivery centre, because the cheaper rate can be the dearer arrangement.
Where the hidden hours go
Every augmented engineer needs someone on your side. That person answers questions, reviews code, unblocks decisions and supplies context that exists only in people's heads. In most teams this is the tech lead or a senior engineer, who is also the scarcest person on the payroll.
Four kinds of work fall on them:
- Direction. Choosing what each person does this week and why.
- Review. Reading code that someone else wrote, in a system only your team knows.
- Context. Explaining the domain, the data model and the unwritten rules.
- Unblocking. Getting access, answers and decisions quickly.
A formula for your own numbers
Estimate the hours per week each augmented engineer needs from your lead. Multiply by the number of people. Compare the result with the lead's working week.
Lead hours consumed = hours per person per week × number of people
Share of the lead's week = lead hours consumed ÷ lead's available hours
The figures below are a rule of thumb to test, not a measurement: three hours per person per week, on an eight-hour day. Replace them with your own.
| Augmented people | Hours per person per week | Lead's time taken | Share of a five-day week |
|---|---|---|---|
| 2 | 3 | Three-quarters of a day | Under one-sixth |
| 4 | 3 | A day and a half | Under one-third |
| 6 | 3 | Two and a quarter days | Nearly half |
| 8 | 3 | Three days | More than half |
At three hours each, two people are a manageable load. At eight, the lead holds a second job and the design and review work they were hired for has slowed. The load rises faster in practice, because a lead splits attention across many threads, and each switch costs time.
Ask your lead for their real figure for one person over a month. Use that, not a guess.
Onboarding, paid again on each swap
The second hidden cost is the time a new person needs to become useful in your system. The newcomer must learn your business terms, your database layout and your unwritten habits, and your senior people do the teaching.
If the supplier can replace someone without your agreement, you pay the cost again and lose the knowledge you paid for. Two clauses protect you:
- You approve every replacement, after an interview.
- The outgoing person overlaps with the incoming one, at the supplier's cost, and writes a handover note.
These clauses matter more to the final bill than a lower day rate does. Compare suppliers on whether they will sign them.
Which model fits which size
These bands are rules of thumb to test against your own team. The real test is how your lead's week looks, as calculated above.
| Team added | What tends to happen | Model that usually fits |
|---|---|---|
| One or two people | The lead answers questions between other work | Staff augmentation |
| Three to five | Coordination becomes a visible part of someone's week | Augmentation, with the formula checked each quarter |
| Six to ten | The lead runs a team they did not choose | A dedicated pod led by its own delivery manager |
| More than ten | Several leads coordinate and nobody owns the outcome | An offshore delivery centre |
The thresholds move earlier when your leads were already full. For the pod and delivery centre models and when to pick each, see ODC, staff augmentation, BOT and GCC compared. For a delivery centre that becomes your own entity, see build-operate-transfer, step by step.
When augmentation is the right choice
- You need a named skill for a bounded period, such as a data engineer during a migration or a reliability engineer during a scaling problem.
- Your delivery process already works and you only need more hands inside it.
- The duration is short or uncertain.
- You want day-to-day control of priorities.
A related question is cost against hiring. The cost of custom software in India explains what drives day rates and team size in a project quote.
How to make it work
- Brief for a gap, not for a headcount. "An engineer who has moved a Tally ledger into an ERP" attracts someone who has done it. "Two backend engineers" attracts whoever is free.
- Interview each person. If you cannot meet them, you are accepting availability and not fit.
- Write handover into the contract. Documentation and a knowledge-transfer session are conditions of the engagement.
- Give each person one named owner on your side. Not a rota of whoever has time.
- Review monthly. Check output, check lead hours, and decide whether to add, hold or change model.
What goes wrong
The common failure is to treat augmented engineers as interchangeable capacity. Nobody owns the result, nothing carries over when people rotate, and the team concludes that outsourcing does not work. The model was stretched past its range. When your lead's share of the week passes about half, switch to a model where the supplier carries the management load. That load is the service a pod or a centre sells.
A short worked check
Take the table above and ask three things this week. How many hours did your lead spend on augmented staff last month? What did the lead stop doing as a result? Which release or review slipped? If the answers are "most of a week", "design work" and "two reviews", the cost has already arrived, and the rate comparison no longer decides anything.
Questions buyers ask
Is augmentation cheaper than a pod?
It is cheaper per hour, and not always per result. Add the lead's hours, priced at their salary, to the rate before you compare.
Can the supplier manage the people for us?
Then you want a pod or a delivery centre. In augmentation, you direct the work.
What should the contract say about replacements?
Your right to interview and approve every replacement, an overlap period at the supplier's cost, and a handover note from the outgoing person.
How do we convert augmented staff to our own employees?
Ask for the terms before you sign. Some suppliers charge a conversion fee that shrinks over time and then disappears; others forbid conversion.
Where Brihat Infotech fits
Team augmentation at Brihat Infotech places named specialists (backend, frontend, mobile, data, DevOps and QA) inside your process. You interview each person, and any replacement overlaps with the person leaving, at Brihat's cost. For the whole range of models, see the offshore engineering models guide.
