Oh yes, you did say that, sorry. I only responded to your first point and then remembered the second myself.<p>PERT is taught as a time based planning tool but it also has a earned value element. The tools for that have moved on too.<p><a href="https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Earned_value_management" rel="nofollow">https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Earned_value_management</a><p>I suppose the unpacking effect does make more sense though, over CPA.<p>&quot;How long will it take?&quot;<p>&quot;6-8 weeks&quot;<p>So what do you put in CPA - 6, 7, 8 ? PERT says 7.
