Overallocation

Your best developer just missed a deadline for the first time. Your senior designer delivered a deck with typos — something that never happens. The project manager who's always calm just snapped at a junior in standup.

The diagnosis? Almost always overallocation.

It happens gradually. A person is great at their job, so they get pulled onto more projects. Each PM thinks they only need "a few hours," but nobody's looking at the total. Before you know it, someone scheduled for 160 hours in a month has 210 hours of allocations stacked against their name.

The Compounding Effect

Overallocation doesn't just cost you the overage hours. A developer at 130% capacity doesn't produce 130% of the output — they produce maybe 90% at lower quality, because context-switching between too many projects kills focus. Research consistently shows that juggling 4+ projects simultaneously can waste 20-40% of productive time on switching alone.

Then there's the invisible tax: the overallocated person starts cutting corners, skipping documentation, avoiding code reviews. Technical debt piles up. And when they inevitably take sick leave from stress, their entire stack of projects stalls at once.

Catching It Before the Damage

The fix isn't complicated — you need visibility. When your capacity planning tool flags someone in red (over 100% utilization), that's your signal to act. Redistribute work, push a timeline, or bring in someone from the resource pool.

The hard part is saying no. When a client asks for "just one more thing" and your team's already maxed, workload balancing means protecting your people — even if it feels like you're slowing down. You're not. You're preventing the crash that costs far more than a delayed sprint.
