What-if scenarios: test a decision before you make it
Before you move a date, add a person or cut scope, test it on a copy. Sen compares the two plans for you.

These are the eight planning threads the Krong course is built around. The highlighted ones are covered here. What are the planning threads?
In one lineThe cheapest place to make a mistake is on a copy.
The method
- Copy the plan as a what-if.
- Change one thing: a duration, a start, a team size.
- Compare it with the original.
- Decide, and keep the plan you chose.
What Sen compares
| Measure | Why it matters |
|---|---|
| Duration and finish date | Does the change reach the date? |
| Forecast cost | What does it cost? |
| Critical tasks | Did the critical path change? |
| High and critical risks | Did it add risk? |
Good questions to ask
- What if the supplier is three weeks late?
- What if we add two engineers in week 8?
- What if we drop the pilot?
- What if the launch moves a month?
Keep it honest
Change one thing at a time, so you know what caused the difference. Name each copy clearly. Delete the ones you no longer need.
Questions people ask
Does a copy change the original?
No. A what-if is a separate plan.
Can I compare any two plans?
Yes. Pick any saved plan to compare with the open one.
What if the units differ?
Sen warns you. Compare finish dates, which are always like for like.
