How do you handle changing requirements?

Question

Accepted Answer

Requirements change — markets shift, you learn from users, priorities move. The goal isn't to *prevent* change (that's both impossible and undesirable) but to handle it **deliberately** so it improves the product instead of derailing the project.

## Embrace change, but control it

```text
✓ EXPECT change → build flexibility into plans (don't over-commit far ahead)
✓ ASSESS each change → impact on scope, timeline, cost, other work
✓ Make the TRADE-OFF visible → "yes, but it costs X or pushes Y"
✓ Let the stakeholder DECIDE with full information
✓ COMMUNICATE the new plan to everyone affected
```

The key discipline is the same as scope management: never silently absorb a change. Every change is a conscious trade-off someone owns.

## Why agile helps

Agile is built for changing requirements: short iterations mean you re-prioritize frequently, so a change waits at most one sprint instead of disrupting a year-long plan. Working in small increments limits how much rework any single change can cause.

## Distinguish discovery from churn

```text
HEALTHY change → new learning, better understanding of the problem
UNHEALTHY churn → indecision, unclear goals, no one owning priorities
```

If requirements thrash constantly, the real problem is upstream — vague goals or weak prioritization — and that's what to fix.

## A concrete example

Mid-sprint, user research reveals the planned flow confuses people. Rather than charging ahead, you assess: reworking it costs three days and pushes a lower-priority item. You present that trade-off, the PM agrees, and you adjust — a change that made the product *better*, handled without chaos.

## A common pitfall

Either rigidly refusing all change (shipping something you *know* is wrong) or accepting every change with no impact assessment (chronic slippage and burnout).

## Why it matters

The ability to adapt is a strength — software that can't change is software that's slowly going obsolete.

Handling change well (assess, make trade-offs visible, communicate, work in increments) lets you stay responsive to reality without losing control of delivery.
