Statistical PERT® (SPERT®) is a stochastic estimation technique that lets anyone create probabilistic estimates for bell-shaped uncertainties – for free!
August 12, 2017 – To register for my upcoming webinar with PMI-Toronto (“Stop Predicting, Start Forecasting”), visit PMI Toronto’s event page and register. The cost is only $10 for PMI-Toronto members, and $20 for non-members. You can download my UMD whitepaper, “Stop Predicting, Start Forecasting.” The webinar is scheduled for Wednesday, August 23, 2017, from 8P – 9P (EDT).
July 7, 2017 – “Stop Predicting, Start Forecasting” is the webinar presentation I will give on Wednesday, August 23, 2017, from 8P – 9P (EDT) for the Project Management Institute Southern Ontario Chapter (PMI-SOC), which is the second largest PMI chapter in the world, serving more than 5,000 members in the Greater Toronto Area. This presentation was well-received at the PMI South Florida Professional Development Day in May, and at the University of Maryland (UMD) Project Symposium in March. You can download my UMD whitepaper, “Stop Predicting, Start Forecasting.” Webinar details will be released by PMI-SOC in the coming weeks!
June 10, 2017 – “Protect Your Project Schedule Using the Unified Scheduling” is the presentation I will give on Sunday, June 11, 2017, at the AACE International‘s 2017 Annual Meeting. Learn how to Soothsay your project schedule and budget using the Unified Scheduling Method (USM). USM uses the binomial distribution functions of Microsoft Excel to create a right-sized schedule and budget contingency.
May 28, 2017 – “Stop Predicting, Start Forecasting” is the presentation I will give on Friday, June 9, 2017, at South Florida’s premier event for project professionals, the PMI South Florida Chapter‘s Professional Development Day! Learn the difference between predicting and forecasting future uncertainties, and why it’s better to forecast than predict the future. Can’t attend my presentation that day? You can still download my whitepaper that I wrote for the University of Maryland’s 2017 Project Management Symposium: “Stop Predicting, Start Forecasting.”
March 28, 2017 – “Stop Predicting, Start Forecasting” is the presentation I will give on Thursday, May 4, 2017, at the University of Maryland’s 2017 Project Management Symposium in College Park, Maryland. This presentation will explore the difference between predicting and forecasting uncertain, future outcomes. We’ll examine why meteorologists are called “weather forecasters” (not “weather predictors”) and see how project managers can, like meteorologists, better align stakeholder expectations and improve decision-making through forecasting. UMD’s Project Management Symposium is the premier project management event in the Washington DC metro area, and brings presenters and attendees together for a two-day symposium exploring project management topics in five different tracks, including Agile/IT and Integrated Program Management. If you can’t attend this UMD’s Symposium, you can still download and read my Symposium whitepaper, “Stop Predicting, Start Forecasting.”
March 24, 2017 – Read a whitepaper on Soothsayer™. Soothsayer is a freely-licensed, Excel-based, probabilistic, estimation technique for creating a dynamic, right-sized, contingency reserve for either schedule or cost. Use Soothsayer to develop a project contingency for risks when doing risk analysis, or to add a right-sized buffer in a project schedule or budget based upon the reliability of each task duration or cost estimate. AACE® International will publish this whitepaper in its Transactions for the 2017 AACE® International Annual Meeting, held this year in Orlando, Florida. After reading the whitepaper, try downloading and using Soothsayer™ for Project Risk Analysis.
March 1, 2017 – Released Version 1 for Statistical PERT® Beta Edition (and Version 2.2 of Statistical PERT® Normal Edition). The Beta Edition release is the first production release of Statistical PERT that uses Microsoft Excel’s two beta distribution functions, BETA.DIST and BETA.INV. The beta distribution can model a wide range of bell-shaped uncertainties, even if they are severely skewed, making the Beta Edition the most flexible way to model project uncertainties. The new Version 2.2 of the Normal Edition adds a new Beginners tab that makes it even easier to understand and use Statistical PERT. Read the press release that announces Version 1 of Statistical PERT® Beta Edition.
February 8, 2017 – Released Version 2.1 for Statistical PERT® Normal Edition (and Release Candidate 1 of Statistical PERT® Beta Edition). This version includes a new “SPERT® Normal (Mixed entry)” worksheet that allows for manually-entered 3-point estimates plus global and individual heuristics for generating minimum and maximum point-estimates. This offers estimators the greatest amount of flexibility for creating 3-point estimates. Use global heuristics to generate minimum and maximum point-estimates, or override the global heuristic for any row with either manually-entered, minimum and/or maximum values, or select a row-specific percentage adjustment to the Most Likely outcome to create a unique minimum and/or maximum point-estimates.
January 12, 2017 – Released minor version 2.0.2 to Statistical PERT® Normal Edition (and 0.6 Build 3 of Statistical PERT® Beta Edition). Later in 1Q 2017, a new version will include a new “SPERT® Normal (Mixed entry)” worksheet that will allow for both manually-entered 3-point estimates and both global and individual heuristics for generating minimum and maximum point-estimates.

January 4, 2017 – SPERT® Mobile for Excel® Mobile, Version 1.0.1 Released
SPERT® Mobile is a special adaptation of Statistical PERT for smartphone and tablet users. SPERT® Mobile uses the normal distribution functions of Excel to easily make probabilistic estimates. This specially-sized Excel template displays great on smaller screen sizes. This minor update adds a little better formatting and cell editing.
January 2, 2017 – Statistical PERT® Normal Edition, Version 2 Released
The newest version of Statistical PERT lets you easily make probabilistic estimates using just a single value (most likely) estimate for any uncertainty with bell-shaped risk properties, like: task duration, work effort, expenses, revenue, agile story points, project portfolios, event attendance and more. Improved formatting lets you choose whether to see the left-side or right-side area under the bell-curve. This new version is now branded as the “Normal Edition” of Statistical PERT, indicating that it uses Excel’s two normal distribution functions, NORM.DIST and NORM.INV, and to distinguish it from the Beta Edition. A new development version of the Beta Edition, which uses Excel’s two beta distribution functions, BETA.DIST and BETA.INV, is also available.
