When to Outsource and When to Insource
3 key questions to help you pick the right approach every time.
At STL, we have a unique vantage point.
We operate two sides of the same coin:
A staffing business, where we help clients find full-time hires and fractional talent.
A managed technology business, where we act as a fully outsourced IT department for mid-market companies.
This gives us a distinct perspective on a common leadership question:
When should you build a capability internally and when should you source it externally?
Here are three questions we recommend asking to find the right approach for each situation.
1. Is It a Core Competitive Capability?
Ask yourself: is this area a strategic differentiator, and is it part of why our business wins with clients?
Every function matters.
But not every function is core to your market advantage.
For example:
The ability to manage finances is critical for a venture capital firm, but not for a plumbing company.
In technology, keeping systems online is essential for a software developer, but less so for a roofing company.
If it’s central to your competitive edge, build it internally. You’ll want full control.
If it’s not, consider outsourcing to experts who can do it more cheaply and quickly.
2. When Do You Need Results?
Outsourcing can bring speed.
You’re tapping into talent that’s already vetted, trained, and working as part of a cohesive project team.
Building internally, on the other hand, takes time: Hiring. Training. Onboarding. Coaching. Integrating into your culture.
If the need is immediate (whether short- or long-term) outsourcing often gets you there faster.
But, if you’re investing in a capability for the long haul, building internally may yield more durable returns.
3. How Complex Is the Project?
Sometimes the role you’re hiring for is too broad for one person. That’s where outsourcing can shine.
For example, one of the benefits of STL’s managed IT business is that we can bring ten minds for the price of one.
Instead of hiring a single person to cover network security, endpoint management, data backups, and compliance… you get a team of specialists working together.
If the job requires multiple skill sets that would be impossible for one person to master...
Outsourcing to a team may be the smarter path.
Final Thought
There’s no one-size-fits-all answer.
Asking these three questions helps leaders make clearer, faster, and more strategic decisions about where to invest.
At STL, we help companies find the balance: building what’s core and outsourcing what’s not.
