Estimate time and effort with an outside view instead of relying only on the current plan.

The date arrives before the estimate
A sponsor says the migration should finish in twelve weeks. The delivery team then estimates each work package while that date remains visible.
Your decision
What should the team do before negotiating the final schedule?
Show the best first move
A. Build an independent range from work packages and assumptions before comparing it with the twelve-week target.
Why this move helps
The target can become the reference point for every later estimate. An independent estimate preserves a separate baseline and makes any movement toward the target inspectable.
Evidence still missing
- Independent estimates from the delivery team.
- Dependency and availability assumptions.
- Comparable completed migrations.
Evidence note
The visible target creates an anchoring risk, but the final schedule may still converge on twelve weeks if independent evidence supports it.
Next action
Produce a range without the target in view and record why it changes after comparison.
Best first lens
Anchoring Effect
Use the lens to ask a better question. It does not prove that a person or team has a cognitive bias.
Other defensible lenses
The situation may have more than one explanation.
