There's no such thing as unplanned work.
There's the work in the plan. And there's the work that changes the plan. Calling the second category "unplanned" is a linguistic habit that hides what's really happening — and, like most linguistic habits in delivery, it has behavioural consequences.
The label is the problem
When new work lands mid-cycle, the team has two options: absorb it into the plan, or let it change the plan. Calling it "unplanned" implies a third option — that the work is somehow outside the plan, a disturbance to be complained about rather than a decision to be made.
That framing produces two behaviours:
- Teams squeeze the new work into the existing plan without resizing anything — and watch finishing odds collapse.
- Teams carry resentment about the "unplanned" interruption, which quietly erodes trust between delivery and the business.
Both behaviours are corrosive. Both disappear the moment you stop using the word.
The behavioural shift
Frustration fades when you stop clinging to the plan and start responding to the reality in front of you.
This isn't a call to abandon planning. It's a call to treat the plan as a living artefact, not a sacred one. The plan is a snapshot of the best bet you could make at time T. At time T+1, new information exists. A good plan is one that absorbs the new information visibly. A brittle plan is one that hides it.
In IMIRT terms, this is a Stack the Odds behaviour. Every new item is a bet. Every bet has finishing odds. When you absorb work "silently," you're not protecting the plan — you're stacking the odds against yourself without telling anyone.
Three questions that replace the "unplanned" label
When new work lands, try these in order:
- "What does this cost the current plan?" — name the trade-off in odds, not hours. "Adding this drops Must Have finishing confidence below 95%."
- "Is this worth the trade-off?" — make the decision explicit, in the room, with the people who own the outcome.
- "What comes out to make room?" — if the work is worth the trade-off, something else moves. If nothing moves, the odds move.
None of these conversations require new tooling. They require the discipline to have the conversation — which is exactly the behaviour "unplanned work" lets teams avoid.
The deeper principle
Plans are bets. Changing a plan is changing a bet. That's always allowed, and it's often right. What isn't allowed — or shouldn't be — is hiding the change. Hidden changes are the purest form of stacking the odds against yourself.
The Stack the Odds play walks through exactly how to make the odds visible and the trade-offs explicit, using a simple formula and five behaviours that strengthen fragile work before it breaks. Get the full play with the free IMIRT Playbook.
