Developing a Comprehensive PERT Chart

‘I want to see every task from when we move in, going backwards, to today.’
— Jo-Anne Sinclair

Jo-Anne wanted to see a PERT chart as Bryan had always prepared such charts when managing large projects.  Yes, our renovation and new construction should have such a plan.

And, Jo-Anne then scheduled recurring weekly project review meetings on both of our Outlook calendars, from 8:00 to 8:30 pm every Friday. With no ‘end’ date.

Having thrown down the gauntlet, Bryan responded, ‘Be careful what you wish for.’

PERT Charts

While many people create project plans showing timelines, most of the timelines are ‘hard coded’ and do not reflect the predecessor and successor tasks.  Using Microsoft Project, one can develop a PERT chart first, showing each task and milestone and have lines showing the relationship to each predecessor and successor task.

PERT, is Program Evaluation and Review Technique. As background, according to Wikipedia,

“PERT was developed primarily to simplify the planning and scheduling of large and complex projects. It was developed by Bill Pocock of Booz Allen Hamilton and Gordon Perhson of the U.S. Navy Special Projects Office in 1957 to support the U.S. Navy’s Polaris nuclear submarine project. It was able to incorporate uncertainty by making it possible to schedule a project while not knowing precisely the details and durations of all the activities.

It is more of an event-oriented technique rather than start- and completion-oriented, and is used more in projects where time, rather than cost, is the major factor. It is applied to very large-scale, one-time, complex, non-routine infrastructure and Research and Development projects.”

Let’s see … Very large-scale, one-time, complex, non-routine infrastructure and Research and Development projects.

Perfect.  Bryan set to work on his PC, developing our comprehensive PERT chart.

Here is our first Comprehensive PERT Chart (in PDF form).

    This is so funny ! You’ve been at this for more than a year, and now we’ve decided to do a PERT chart for Joanne.

    BTW, I would venture to guess that her critical end point is “move into 17509 via sereno”, and not “submit leed-h application”….
