The Moment the Plan Becomes Fiction

​

The project plan is approved.

The timeline is ambitious but “achievable.”
The milestones line up cleanly.
The dependencies behave politely.

​

Everyone nods.

This is usually the last moment the plan is treated as a living thing.

Because once execution begins, the plan doesn’t fail loudly.

It fades.
Quietly.
Respectfully.

And everyone pretends this is normal.

In practice, these are the project planning myths that quietly shape expectations long before delivery begins.

​So What Is Project Planning Supposed to Do?

At its best, project planning is not about prediction.

It’s about shared understanding.

A good plan is meant to:

• Align expectations

• Surface trade-offs

• Expose risk early

• Create a baseline for decisions

It is not meant to:

• Guarantee outcomes

• Prevent change

• Replace judgment

When planning is treated as prophecy, disappointment is inevitable.

It isn’t about perfect timelines — it’s about why project plans fail once reality shows up

​

Myth #1: A Good Plan Prevents Change

This myth survives in almost every organization.

If we plan thoroughly enough, change won’t be necessary.

Reality disagrees.

Change happens because:

• Information improves

• Constraints tighten

• Priorities shift

• External forces intervene

A good plan doesn’t stop change.
It gives you something to react from.

​

Myth #2: Once Approved, the Plan Is Stable

Approval feels like certainty.

But approval only means:

• The assumptions were accepted

• The optimism was tolerated

• The risk was deferred

Once delivery starts, the plan enters a hostile environment.

Execution introduces:

• Competing initiatives

• Resource erosion

• Decision latency

• Unplanned dependencies

Stability was never the goal.
Adaptability was.

Myth #3: The Plan Exists to Be Followed

This is where plans suffer the most damage.

Plans are not commandments.
They are conversation starters.

Their real purpose is to help answer:

• What are we trading off?

• What breaks if we change this?

• What risk are we now accepting?

A plan that can’t be challenged becomes theatre.

How Planning Actually Works in Real Projects

In real delivery environments:

• Plans age quickly

• Milestones become aspirational

• Dates become emotional commitments

The plan is still referenced — but selectively.

This is not failure.
It’s survival.

The problem isn’t that plans change.
It’s when no one is allowed to say so.

Why Planning Still Matters (Even When It Breaks)

Despite everything above, planning still matters deeply.

Because without it:

• Chaos has no reference point

• Delays feel personal

• Trade-offs become invisible

• Accountability dissolves

A broken plan is still useful.
A missing plan is not.

The Real Value of a Project Plan

A project plan earns its value when it helps you:

• Explain why something slipped

• Show what changed

• Decide what to protect next

Its success is not measured by accuracy.
It’s measured by decision quality under pressure.

What Experienced PMs Know (And Rarely Say Aloud)

Plans don’t survive projects.

But projects don’t survive without plans.

The tension between those two truths is where project management actually lives.

“Most planning failures don’t come from bad intent — they come from treating plans as commitments rather than hypotheses.”

Field Notes

If you’ve ever watched a perfectly reasonable timeline collapse under impossible expectations, you’ll recognize this pattern in Deadline Olympics.
