What does moving target mean in software engineering?

A moving target refers to requirements, goals, or success criteria that continuously change or shift. In software development, it describes the frustrating situation where specifications are modified frequently during or after work has begun, making it nearly impossible to meet deadlines or deliver what was originally agreed upon.

How do you use moving target in a sentence at work?

You can say 'The requirements are a moving target' to express that goals keep changing. Other common uses include 'We cannot hit a moving target' (impossible to achieve changing goals) or 'Stop making this a moving target' (asking someone to stabilize requirements).

Is moving target formal or informal?

Moving target is neutral in formality. It is used in both casual team discussions and formal project meetings. While it uses a metaphor, it is a recognized business term in tech, making it appropriate for professional communication.

How is moving target different from scope creep?

A moving target emphasizes that the goal itself is unstable and constantly redefined. Scope creep refers to uncontrolled expansion of project scope. You can have scope creep with a fixed target, and you can have a moving target without scope expansion.

When should I use this phrase in meetings?

Use it when discussing why progress is slow, why deadlines are missed, or why planning is difficult due to changing requirements. It is especially useful when advocating for requirement stability or explaining challenges to stakeholders.

Real examples

in a standup

in a code review

"I finished the API according to the original specs, but now the requirements have changed again. We are chasing a moving target here."

in a team meeting

"If the client keeps modifying what they want, we will always be working on a moving target. We need to lock down the requirements first."

Don't say this

Handle with care. Often confused with 'scope creep' — moving target refers to constantly changing requirements, while scope creep is uncontrolled expansion of project scope.

✕The moving target needs to be completed by Friday.

✓The target keeps moving, so we cannot commit to Friday.— A moving target is not a task itself; it describes the unstable nature of the goal.

✕We are moving targets for this project.

✓The project requirements are a moving target.— People are not moving targets; requirements or goals are. The phrase describes instability, not people.
