Tips on using this forum..

(1) Explain your problem, don't simply post "This isn't working". What were you doing when you faced the problem? What have you tried to resolve - did you look for a solution using "Search" ? Has it happened just once or several times?

(2) It's also good to get feedback when a solution is found, return to the original post to explain how it was resolved so that more people can also use the results.

There are two competing methods to the calculation of the critical path. One method boasts the adoption by Oracle Primavera P6 while the other is considered the appropriate approach on the Project Management Institutes (PMI)

Dear Emily,

Your proposition is ridiculous and at least 6 top 10 years out of date - the so called ‘expert’ who wrote the piece you are linking to has non idea what he is talking about.  There were two manual calculation options - the correct way and a simple ‘old way’ used decades ago when major schedules were calculated by hand (ie, the 1960s, 70s and into the 80s.  See:

In particular, the PMI exams have needed the correct calculations for at least the last 6 years, probably longer.

Pat (and I'm old enough to have used the 'old way' on schedules for multi-million dollar projects).

Suck Teach Eggs Grandma - rearrange to find a well known phrase or saying.
