Hello Experts,

 

What % of total number of activities in a baseline schedule should ideally be lying on the critical path (TF=0), a number from your extensive experience / best practice would suffice.

 

thank you

    There is no single answer to

    There is no single answer to this - small schedules (low number of activities) will tend to have more activities on the critical path than large schedules, but my heuristic is around 20% is good, below 20% better and knowing the probability of achieving on-time completion is heading 'south' once the percentage gets above 20% (particularly if there are multiple critical paths).
