Most organizations make their planning as if the world behaves nicely.
As if no one gets sick. As if an order never changes. As if a customer doesn't suddenly call with "it has to be today" ... and then it's Tuesday.
- 07:12 - someone cancels.
07:18 - an urgent order comes in.
07:30 - a team is at the wrong location because the latest version got stuck "somewhere".
08:05 - the planner starts piecing things together, calls around, adjusts, sends screenshots… and hopes everyone sees the same truth.
This is exactly why "automated planning" is often misunderstood. The goal is not: to generate a schedule once a week.
The goal is: continuous rescheduling without chaos, with control over impact, rules, and communication.
The real enemy: version chaos and differences in interpretation
In Excel or separate tools, you almost always get the same symptoms:
- multiple versions ("who has the latest?")
- many manual corrections (with errors as a byproduct)
- invisible impact (a small change causes downstream trouble)
- discussion afterwards (hours, surcharges, relocations, responsibility)
The problem is rarely "bad planners". The problem is that your system lacks a real-time decision engine is.
What intraday rescheduling really means
Intraday rescheduling is not "changing everything as soon as something changes".
Intraday rescheduling means:
- Quickly finding a feasible new solution within the real constraints
- Minimal changes where possible (maintaining plan stability)
- Making impact visible: what changes, for whom, and what does it cost?
- Respecting rules: skills, certificates, rest times, staffing, priorities, locations, materials
- Automatically following up on communication: the right info to the right people
So you don’t want "a schedule". You want a system that repeatedly converges back to a workable reality under pressure.
Intraday rescheduling is also about protecting your margin in practice
Any last-minute change that you don’t catch immediately almost always translates to loss: downtime, extra movements, overtime, incorrect deployment, or late communication. By rescheduling during the day with real-time insight and quick recalculation, you avoid those "margin leaks" while the operation is still running.
The 4 building blocks of good intraday rescheduling
1) Constraints are not optional
Availability, schedules, competencies, certificates, locations, materials, rest times… If you don’t treat these as hard inputs, you are not planning, you are gambling.
2) Priorities must be explicit
Urgency over routine? Key customer over internal task? Safety over speed? An engine can only be smart if you define what "profit" means.
3) Exceptions must be a first-class citizen
Sickness, absence, delays, extra work, no-shows… that is not an edge case. That is daily business.
Good software therefore has flows for:
- quick rescheduling
- escalations/approvals
- logging: who changed what and why
4) Schedule stability is a KPI
Every change has a cost: unrest, miscommunication, errors. An intraday approach must therefore not only "reschedule quickly", but also disrupt as little as possible.
How do you measure if your intraday planning works?
A few KPIs that actually mean something:
- Time-to-recover: time between disruption and a feasible plan again
- Fill rate: how many shifts/tasks effectively filled (with the right skills)
- Schedule stability: number of last-minute changes per team/shift
- Overtime & premium hours: are they rising due to ad-hoc decisions?
- Operational noise: calls/messages/interrupts needed to "fix it"
If those metrics improve, you get the effect that everyone wants but can hardly "buy": calm.

A little reality check
An organization with 50–500+ people can often just "survive" on heroics: one or two planners carrying everything in their heads. But as volume, variation, and exceptions increase, heroics become expensive:
- higher error rate
- higher stress
- more dependence on individuals
- slower response
- more discussion afterwards
Intraday rescheduling is not a luxury feature. It is continuity.
