Read the result carefully
Find out where the result comes from.
The idea
A single total can hide important details.
Look at which periods helped, which hurt, and which assumptions had the biggest effect.
A small example
These are invented net results for three separate periods:
| Period | Result |
|---|---|
| A | +8 |
| B | −3 |
| C | −4 |
The total is +1, but only one of the three periods was positive.
That does not settle whether the rule is useful. It tells you what needs a closer look.
Try it
Write a three-sentence review:
- What does the total say?
- What does the breakdown add?
- What would you check next?
Check your work
A useful answer mentions both the positive total and its dependence on period A. A next check could examine costs or another untouched period.
Keep the conclusion as narrow as the evidence. You are now ready to turn the learning example into code, even if the rule has not earned a place in a real strategy.
