Staff augmentation vs managed services
Staff augmentation adds outside people to your team, and you direct their work. Managed services hand a running service to a provider, who answers for the outcome. Choose augmentation when you have a roadmap and want control, and managed services when you want the result looked after.
The two models side by side
The main difference is who directs the work and who answers for the result.
| Question | Staff augmentation | Managed services |
|---|---|---|
| Who sets the tasks? | You do. The people join your team and work from your priorities. | The provider does, inside a scope agreed in writing. |
| Who answers for the result? | You do. The provider answers for the quality and conduct of its people. | The provider does, against the service levels in the agreement. |
| What do you buy? | Capacity and skills, by the month, by the hour or as a team. | A service: for example monitoring, fixes, updates and a number of requests. |
| Best for | Building. A roadmap, a backlog, a skill gap or a peak in work. | Running. Systems that are live and need to stay healthy. |
| How it changes | Add or remove people at short notice. | Change the scope or the plan at renewal or by agreement. |
| What you need in-house | Someone to set priorities and review the work. | Someone to raise requests and check the service reports. |
When staff augmentation fits
It works when you know what you want built and want more hands or a skill you lack.
You have a roadmap
The work is ongoing and you can keep the team busy with clear priorities.
You lack one skill
You need a database, cloud or reporting specialist for a stretch, not a permanent hire.
You want control
You prefer to direct the work, review it and keep the knowledge close to your own team.
Your workload moves
Demand rises and falls, and you want to scale the team up or down.
You want to move faster
Hiring takes months. Adding trained people to an existing team takes much less time.
You have a manager for it
Someone on your side can set tasks every day or every week and answer questions.
When managed services fit
It works when the solution is built and you want it kept running without managing people.
The system is live
It needs fixes, updates, small changes and regular reviews, not a build.
You do not want to manage people
You want to send a request and get a result, with a response time agreed beforehand.
You need predictable cover
A written scope and response times make the work easier to plan and to budget.
Your in-house capacity is stretched
There is nobody in-house to direct developers or to be on call.
You need a record
Reports show what was asked, what was fixed and how fast.
The scope is stable
Requests are small and regular, and the list of what is covered rarely changes.
Five questions that decide it
Answer these in order. Most teams know the answer by the third.
- 1
Is the work building or running?
New features and projects point to augmentation. Keeping a live system healthy points to managed services.
- 2
Do you want to direct the work?
If yes, augmentation. If you would rather state the outcome and let the provider organise it, managed services.
- 3
Can you keep people busy?
Augmentation pays when there is enough clear work. If the backlog is thin, you are paying for idle time.
- 4
Is the scope clear and stable?
A clear scope suits managed services or a fixed project. A moving scope suits augmentation.
- 5
Who owns the knowledge afterwards?
Augmentation builds knowledge inside your team. With managed services much of it stays with the provider, so ask for documentation.
Or a mix
Many teams use both
The two are not exclusive, and a third option sits beside them.
Build with augmentation, then hand over
Use extra developers to build, then move the live system to a support plan.
Managed cover plus extra hands
Keep a support plan for the live system and add developers when a big piece of work arrives.
A fixed-scope project
When the scope is clear and you want a delivered result for an agreed price, a project can beat both.
Before you sign
What to ask any provider
For staff augmentation
Who are the people, and what is their level? What are the monthly hours, the notice period and the replacement terms? Who owns the code? Is there an NDA first? Who manages them day to day?
For managed services
What is covered and what is not? What are the response and fix times? How do you raise a request? What reports do you get? What happens when you want to end it?
How AscenWork works
Both, on our terms
We offer both, and we say plainly which fits. These are our standard terms for developers.
- Monthly developerOne developer for 176 hours a month, with a minimum of one month.
- Part-timeFrom 20 hours a month, for smaller or occasional needs.
- Dedicated teamA team of an agreed size that works as part of yours.
- You direct the workA project manager from AscenWork checks progress and sends you an update every day.
- You own the codeWe sign an NDA before we start, and the code and files are yours.
- 30 days’ noticeScale the team down with 30 days’ notice.
Staff augmentation and managed services questions
What is the difference between staff augmentation and managed services?
With staff augmentation, outside people join your team and you direct their work. With managed services, a provider takes responsibility for a running service and answers for the result against agreed service levels.
Which is cheaper, staff augmentation or managed services?
It depends on the workload. Augmentation is priced by people and time, so it is good value when there is steady work for them. Managed services are priced by scope or plan, so they suit regular, smaller requests. Compare quotes against the work you actually have.
Who manages the people in staff augmentation?
You set the tasks and priorities. With AscenWork, a project manager from our side checks progress and sends you an update every day.
Who is responsible for quality in each model?
In staff augmentation you are responsible for the direction and review of the work, and the provider for the conduct and skills of its people. In managed services the provider is responsible for the outcome set out in the agreement.
Can I use both at the same time?
Yes. A common pattern is a support plan for the live system plus extra developers when a large piece of work arrives.
When is a fixed-scope project better than either?
When the scope is clear and you want a delivered result for an agreed price, with changes handled through a change request.
How do I move from staff augmentation to managed services?
Document the system, hand over the code and access, agree what the support plan covers, and set response times. Do this before the augmented team winds down.
