Many AEC businesses grow into the same bottleneck: one capable IT person who has been there for years, knows everything and is now expected to be helpdesk, project engineer, security officer and strategist simultaneously. Holidays become risky. Big projects stall. Nobody sleeps well.
The problem is structure, not the person
A single individual, however good, cannot provide cover, breadth and progression at once. The choice is usually framed as “hire more staff or outsource everything”, but both options discard something valuable: either budget efficiency or hard-won internal knowledge.
How co-managed arrangements work
Co-managed IT splits responsibilities deliberately. Typically the internal team keeps what they are best at, often user-facing support and institutional knowledge, while the partner provides monitoring, escalation engineering, project capacity, security operations and strategic input.
The internal IT manager gains a deep bench behind them, cover when they are away and specialists to call on, rather than a competitor for their role.
Making it succeed
Clear boundaries are everything: documented ownership of each responsibility, shared tooling and ticketing and honest reporting to leadership from both sides.
WIT runs co-managed arrangements alongside internal teams at several practices, usually beginning with monitoring and escalation, then expanding as trust builds. It is often the most cost-effective step between “one person doing everything” and a full internal department.
