Leadership Rule #8: Adhere to the Schedule...or Change the Schedule
A schedule is a commitment—not a suggestion and one of the quickest ways to tell whether a project is being professionally managed is to look at its schedule. Not whether it’s perfect, but whether it’s accurate.
The best project teams don’t treat the schedule as something they create at the beginning of a project and forget about. They treat it as a living management tool that reflects reality and drives decisions every single day.
Unfortunately, that’s not always what happens. I’ve seen two very different approaches over the years.
-The first team misses a milestone and quietly moves on. They reassure themselves they’ll "make it up later." Progress reports continue to show the original dates, everyone knows they’re no longer realistic, and eventually the schedule becomes little more than decoration.
-The second team misses a milestone and immediately asks a different question:
"What does this mean for the rest of the project?"
They evaluate the impact, update the schedule, communicate the changes to stakeholders, and develop a recovery plan if one is possible.
Neither situation is ideal. But only one reflects disciplined project management.
A Schedule is a Decision-Making Tool
A good project schedule should answer critical questions almost instantly:
- • Are we ahead or behind?
- • What activities are driving completion?
- • What work has become critical?
- • Where are the risks?
- • How much schedule contingency remains?
- • Which decisions need to be made today?
Those answers are only valuable if the schedule reflects reality.
An outdated schedule doesn’t just hide problems—it creates new ones:
- • Leadership begins making decisions based on incorrect information.
- • Resources are allocated to the wrong priorities.
- • Contractors lose confidence in management.
- • Owners stop trusting progress reports because they no longer match what they’re seeing in the field.
Eventually, people stop using the schedule altogether. At that point, you’ve lost one of the most valuable management tools on the project.
There Is Absolutely Nothing Wrong with Changing the Schedule
Some people view updating a schedule as admitting failure - I see it differently.
Changing the schedule isn’t failure, but pretending nothing has changed is.
Construction projects are dynamic;
- • Weather changes.
- • Material deliveries slip.
- • Design revisions occur.
- • Permits take longer than expected.
- • Unexpected field conditions emerge.
- • Productivity fluctuates.
None of that is unusual. What’s important is acknowledging reality quickly enough that the team can respond intelligently.
Sometimes that means resequencing work and sometimes it means adding resources.
Sometimes it means negotiating milestone changes with the owner, and sometimes it means accepting that a completion date has moved.
Reality doesn’t care what date appears on last month’s schedule.
Recovery Plans Only Work If They’re Based on Reality
I’ve seen organizations demand recovery plans built around schedules everyone knows are impossible. The result?
Teams spend more time explaining why they missed unrealistic dates than actually solving the problem.
A credible recovery plan starts with an honest schedule. Only then can leadership evaluate options, compare alternatives, understand the cost of acceleration, and decide whether recovery is worth pursuing.
Hope is not a scheduling strategy. Facts are.
Respect the Schedule
- • If the schedule is accurate, use it.
- • If conditions change, update it.
- • If recovery is possible, build a realistic plan and execute it.
- • If recovery isn’t possible, communicate the new reality early so stakeholders can make informed decisions.
The schedule exists to support better decisions—not to preserve yesterday’s expectations.
The best project managers I’ve worked with understood this.
They respected the schedule enough to keep it honest.
Because an honest schedule builds credibility.
And credibility is one of the most valuable assets a project team can have.
Rule #8 is simple: Adhere to the schedule...or change the schedule. Just don’t pretend the original plan is still valid when everyone knows it isn’t.
