A = B + C
Example
Assume you’re organizing a hiking trip and want to know how long it will take to reach the peak of a mountain. You believe:
– In the best-case scenario, with excellent weather and circumstances, it may take 4 hours.
– In the worst-case scenario, with difficult terrain and severe weather, it may take up to 8 hours. However, under typical circumstances, it will most certainly take roughly 6 hours.
Here’s how a triangle estimate would be used:
– The best-case situation is four hours.
– The most likely scenario is 6 hours.
– The worst-case situation is 8 hours.
Using the triangle technique, add the best-case, most probable, and worst-case numbers together and divide by three:
[Triangular Estimate = (Best Case + Most Likely + Worst Case) / 3 ] [Triangular Estimate = (4 + 6 + 8) / 3 ] [Triangular Estimate = 18 / 3 ]
As a result, your triangular estimate for summit time is 6 hours. It’s a method of generating a single, balanced estimate that takes into account both optimistic and pessimistic situations, as well as what’s most likely to happen, assisting in project planning by evaluating many alternatives.
