Why insource?
- Insourcing should solve a business problem: weak ownership, slow change, excessive dependency, knowledge loss or the need to build strategic capability.
- The objective is not to bring everything in-house; it is to retain accountability and the capabilities that genuinely need business context.
Design the target operating model first
- Define service ownership and decision rights.
- Identify roles that must exist internally before supplier scope is reduced.
- Document which services remain external and how they will be governed.
- Define support tiers, SLAs, escalation and on-call expectations.
- Separate BAU ownership from temporary transformation capacity.
Transition knowledge, not just tickets
- Transfer architecture, integrations, runbooks, recovery procedures, privileged access, known issues, vendor contacts and business-calendar dependencies.
- Make documentation and knowledge acceptance explicit transition deliverables.
Integrating acquired businesses
- Bring acquired environments into common governance before forcing technical standardisation.
- Stabilise support and access first, then rationalise platforms and suppliers.
- Make the future BAU owner part of the integration project.
Key lessons
- Outsourcing execution does not outsource accountability.
- Insourcing without knowledge transfer simply moves the queue.
- Recruitment should follow the target operating model.
- A hybrid model is usually more practical than ideological full insourcing.
