Experienced Team

Experienced professionals never proceed directly to completion, but follow from the starting point along an arc, consisting of points equidistant from both the starting point and the result point (circumference).

After traveling halfway, the team usually stops to think and rushes toward completing the task. (fig. 1) Thus, the formula for expected execution time looks like this:

t = R × (π + 1) + β

where t is the time spent to achieve the goal, and R is correctly estimated initial timeframes for project completion.

Unexperienced Team

Here everything is simpler - an inexperienced team covers with their chaotic movements the entire area formed by the figure of the experienced team. The formula is also trivial:

t = R² × π + β

Pay attention to the constant β - this is Bobyk's universal number. According to Bobyk's theorem, any literate specialist working alone in panic will write the entire project in β time, regardless of the complexity of the project itself. It has been empirically determined that Bobyk's number equals about two weeks.
