January 2, 2020 – Released Version 4 of Statistical PERT Normal Edition! This new version includes a real Monte Carlo simulation tab to use with a single, random variable and a new agile release burn-up chart. Plus you can use your own, explicit standard deviation (when you are using historical data) and you can choose from 10 subjective judgment options for the most likely outcome (up from just 7 options). Some other, minor changes, too throughout. Download Version 4 from this site or from GitHub.
December 9, 2019 – I’m working on Version 4 of Statistical PERT Normal Edition, to be released early in 2020. This new version will include a simple Monte Carlo simulation model, plus more agile-focused features, including a new sprint (iteration) burn-up chart to forecast agile software development. Want a sneak-peak at the latest version? Download Version 4 from GitHub. Note: Version 4 is under development and has not been fully tested.
September 28, 2019 – I’ve updated the Soothsayer templates to Version 1.1. This is a minor update which adds 800 additional tasks to the Soothsayer for Project Contingency spreadsheet, and makes some very minor formatting changes to Soothsayer for Project Risk Analysis spreadsheet. If you’re not familiar with Soothsayer, learn more by reading this whitepaper to discover how using Excel’s binomial distribution functions can help you choose a right-sized schedule and budget contingency for your project.
September 13, 2019 – Pluralsight has published my newest course, Forecasting for Agile Teams. In this course, you will create and share forecasts for your agile software development effort. First, you will learn why forecasting is important. Next, you will discover how to forecast using Microsoft Excel and Statistical PERT, which is available for downloading on this site right here.

This will be a one-hour, non-recorded webinar covering how to create forecasts for agile teams using Statistical PERT. Webinar registration details will be available in the coming weeks.
July 16, 2019 – I wrote and published a new LinkedIn article, entitled “The Küsters Estimation Problem,” which offers a forecasting approach using Statistical PERT Beta Edition Version 2. I wrote my article on the same day that popular LinkedIn “Thought Provoker,” Michael Küsters, wrote this blog article on his personal blog. Michael has great insights on many agile-related topics — highly recommended!
July 13, 2019 – I released a big upgrade to Statistical PERT Beta Edition Version 2! The Version 2 upgrade adds the same data visualization features as what the SPERT Normal Edition has: tri-colored combo charts to show the beta distribution’s bell-curve, plus row-level line Sparklines to show the bell-curve for each row, and an all-new Agile Forecast tab to calculate agile release/delivery dates. There are some minor formatting updates, too. Download the latest Version 2 of Statistical PERT Beta Edition from this site or from GitHub. Also, Statistical PERT Normal Edition bumped up to version 3.0.3 for some very minor format updates.
July 9, 2019 – I released another very minor update to Statistical PERT Normal Edition Version 3. The version 3.0.2 update does a little formatting to some worksheets and replaces the footer link to the GNU GPL webpage so it uses HTTPS instead of HTTP.
July 1, 2019 – I released minor updates to my two Soothsayer™ spreadsheets. Version 1.0.2 simply adds the full text of the GNU General Public License to both Soothsayer for Risk Analysis and Soothsayer for Project Contingency. Also, I created a new GitHub repository for Soothsayer to manage future changes to these spreadsheets. Download the latest version of Soothsayer either from GitHub or navigate to this site’s FREE Downloads page and look for the Soothsayer bonus download links on the right-side of that page.
June 30, 2019 – I released a minor update to Statistical PERT Normal Edition Version 3. The Version 3.0.1 update simply adds the full text of the GNU General Public License (Version 3) and updates the worksheet footers to expressly require that all verbatim and modified copies of Statistical PERT spreadsheets retain the copyright notice, including the author’s name, copyright year, and that the spreadsheet is licensed under the GNU GPL. The forthcoming new Beta Edition Version 2 will contain the same updates when I release SPERT Version 2 later this summer. You can get a sneak peak of Beta Edition Version 2 by visiting GitHub and downloading from the version_2 branch of the spert-beta repository.
June 26, 2019 – I have begun working on Version 2 of Statistical PERT Beta Edition! Version 2 will give the Beta Edition the same data visualization features as Version 3 of Statistical PERT Normal Edition (that is, line Sparklines for each row, plus tri-colored bell-shaped curves for summary combo charts). If you’d like to follow this development and try-out the new features as I add them, you can download Version 2 from GitHub using the version_2 branch of the spert-beta repository.
June 23, 2019 – To increase awareness and public adoption of Statistical PERT, I’ve created two public repositories on GitHub. Using GitHub will provide greater transparency to the ongoing development plans for Statistical PERT. The spert-normal repository will maintain the latest version of Statistical PERT Normal Edition, while the spert-beta repository will maintain the latest version of Statistical PERT Beta Edition.
Moreover, I’ve created two public projects on GitHub, too, which will show anyone who’s interested what my development plans are for enhancing both editions of Statistical PERT. The SPERT Normal Edition Development project will show you future and in-progress enhancements for SPERT Normal Edition, while the SPERT Beta Edition Development project will show you future and in-progress enhancements for SPERT Beta Edition. I haven’t populated these two projects with enhancement ideas just yet, but I will in the weeks to come, especially as I work on Version 2 of Statistical PERT Beta Edition this summer.
If you’d like to participate in the development of Statistical PERT, please contact me!
May 13, 2019 – Last week, Anne Johnson, PMP, from the United States Census Bureau presented at the University of Maryland’s Project Management Symposium 2019. Her presentation, “Capturing Costs & Value of Research Products” included a brief explanation of how the U.S. Census Bureau uses Statistical PERT to estimate project costs. Using Statistical PERT inside their 8-step process, the U.S. Census Bureau has reduced the number of projects that are over-budget by creating better, more reliable cost estimates up-front. Download and read the full whitepaper.
April 29, 2019 – Today I had the privilege of guest lecturing to students enrolled in the same graduate degree program I completed in 2014: the Master of Science in Project Management (MSPM) from The George Washington University’s School of Business. I lectured on how students can easily use Statistical PERT to create task estimates with the same probability of success, which is a necessary pre-condition to use the Unified Scheduling Method, a technique developed by GWU’s own professorship, Dr. Homoyoun Khamooshi and Dr. Denis Cioffi.
March 19, 2019 – Released a minor update to Statistical PERT Beta Edition (Version 1.2). This minor update replaces the link to my old Pluralsight course and points learners to my new course, Easily Estimate Projects and Products. The footer license and no-warranty claim also had minor updates, too. I’ll begin working on the full version upgrade of the Beta Edition in the next couple of months. Beta Edition Version 2 will receive the same data visualization features as what the Normal Edition Version 3 just received.
March 16, 2019 – This week, Pluralsight published a brand-new course, Easily Estimate Projects and Products, which introduces and demonstrates Statistical PERT Normal Edition Version 3. This course offers the most complete way to understand how Statistical PERT works, how to use it to solve practical estimation problems, and how to modify the template to better suit your estimation (forecasting) needs. Watching the course also helps to defray the cost of this website, so I encourage you to watch the course!
March 10, 2019 – Today I released the brand-new, Version 3 of Statistical PERT Normal Edition! Version 3 includes new data visualization features to help see the uncertainty of your estimates. Version 3 includes row-level Sparklines to visualize the uncertainty of a single, 3-point estimate, plus new, tri-colored combo charts to see the uncertainty at an aggregate level. Moreover, Version 3 includes side-by-side comparison of up to three scenarios in the Agile Forecast tab, and Version 3 includes a new, “Super Simple SPERT” tab for easy, beginner-level forecasting. The Beta Edition of Statistical PERT will receive the same data visualization upgrade by late summer 2019.
November 18, 2018 – I released a new, minor upgrade to Statistical PERT Normal Edition. Version 2.4 makes a small change to the Agile Forecast tab so the confidence probability associated with the agile release date better aligns with a Monte Carlo simulation (using SPERT’s “Medium Confidence” in the Most Likely outcome). All Statistical PERT results are routinely compared with Palisade’s @Risk Monte Carlo simulation plugin to assure users of Statistical PERT’s accuracy.
October 26, 2018 – I have struck an agreement with Pluralsight, a leading producer of online training videos for IT and creative professionals, to create a brand-new training course that will replace my now-dated, 2015 course that first introduced people to Statistical PERT. My new, shorter, 2-hour Pluralsight course will be called, Easily Estimate Projects and Products. In this course, I will show how to create estimates and forecasts using the forthcoming Version 3 of Statistical PERT Normal Edition. My new Pluralsight course and the new version of Statistical PERT Normal Edition are both targeted for a January, 2019 release!
October 21, 2018 – In anticipation of new Version 3 of Statistical PERT Normal Edition (January 2019), I updated SPERT® Mobile to a new Version 2a. This is an early-release version. It includes a new cell containing a line Sparkline that shows the implied, bell-shaped, normal distribution curve. Adding Sparklines to SPERT will be part of the new, visual elements that will be part of both editions (Normal and Beta) of Statistical PERT in 2019. Note: You must have Excel® Mobile installed in your smartphone to make use of SPERT Mobile. Download SPERT® Mobile Version 2a now! It’s one of the “Bonus” downloads available on this site.
October 9, 2018 – I’m preparing a new Version 3 of Statistical PERT Normal Edition with an expected release of January, 2019. Version 3 will have new visual features that show the implied, bell-shaped curve for every row with a valid, 3-point estimate. Version 3 will also include a new bar chart showing the bell-shaped, normal distribution curve for the summary row for all 3-point estimates combined. You can download a preview of this new release by going to this site’s Beta Blog and going to that site’s Download page.
October 3, 2018 – I’m heading out to Los Angeles this week for the biggest event of the year for project managers: the PMI Global Conference 2018. I’ll be presenting a team-building and training framework in this presentation: Collabinart: Build Team Collaboration Through Interpretive Art. If you’re attending this event, contact me and let’s meet up!
September 22, 2018 – I’ve published a new, minor release of Statistical PERT Normal Edition (version 2.3) which includes a new, experimental worksheet for creating a release forecast for agile teams based upon story points, user stories or features. Agile forecasting will be a major development emphasis for Statistical PERT in 2019 and beyond. If you use this new worksheet for creating release forecasts for your agile team, please contact me — I’d love to learn how well Statistical PERT satisfies your agile release forecasting needs.
May 1, 2018 – I will be presenting at two upcoming Project Management Institute (PMI) events this year. Locally, I will be presenting “Collabinart” — a collaboration activity using famous, painted artwork — at the PMI South Florida Chapter’s premier event, Professional Development Day, on June 15. Then, this fall, I will present “Collabinart” at the 2018 PMI Global Conference in Los Angeles. The PMI Global Conference runs from October 6 – 8. As these dates draw nearer, I will post more details on my presentation here on this website. If you’re planning to attend either event, be sure to let me know so I can meet and greet you!
March 1, 2018 – I’m beginning a new initiative to adapt Statistical PERT to better fit the needs of agile teams who need to create release forecasts for their products. When I created Statistical PERT in 2014, my goal was (and is) to create simple, free, easy-to-use estimation tools that enable people to make probabilistic estimates for uncertain future outcomes. Read more about this on the Beta Blog and download a development-only build of Statistical PERT geared specifically for the needs of agile teams.
February 20, 2018 – I will present “Stop Predicting, Start Forecasting” at the Palm Beach State College’s Math Awareness Week at the Lake Worth, FL campus.

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.
