[Planning] What makes a project plan realistic?

Example Answer

A realistic project plan reflects how the work will actually get done, not just how people wish it would go. It has clear scope boundaries, visible dependencies, credible sequencing, real ownership, and assumptions that are out in the open instead of buried underneath the dates.

It also makes room for the fact that projects are not just task lists. A plan can look organized and still be weak if it ignores decision timing, stakeholder inputs, approval paths, or external dependencies that clearly affect delivery. If those things are missing, the plan may be neat, but it is not realistic.

I also listen to whether the team believes the plan. If the people closest to the work can already see compression, missing conditions, or hidden risk, that's usually a signal worth taking seriously.

Common Poor Answer to Avoid

"A realistic plan is one with enough detail and a strong timeline."

Why it's weak

That's too thin. Detail and a timeline are not what make a plan realistic if the logic underneath them is weak.

Why this works

It sounds grounded in actual delivery experience. It explains realism in terms hiring managers care about: sequencing, decisions, assumptions, and team credibility.
