My Book Report on the Project Management Institute® Practice Standard for Earned Value Management

Exposure Working Draft, Preface, Chapters 1 & 2

Way back when I was firmly ensconced in the Project Management Institute’s (PMI®’s) stable of contributors and writers, I was asked to help write the Practice Standard for Earned Value Management. The team had some of the most brilliant minds in project management, including Gary Humphries and James Wrisley, and working with them was a blast. However, some of the others on the team made the overall project very frustrating for me, and, when I was asked to review the Exposure Working Draft’s Preface and first two chapters, it showed.

Many of the issues I took on would, I discovered later, manifest in other parts of PMI®’s codex, which made several parts of the PMBOK Guide® easy pickings for (Marlin Perkins alert!) my new book, Game Theory in Management (http://www.ashgate.com/default.aspx?page=1751&pageSubject=312&calcTitle=1&priorityone=1&title_id=11616&edition_id=15149). But when I swerved across my long-ago book report, I discovered it was illustrative of some of the reasons why PMI® has, in my opinion, abandoned the role of thought leader in the field of project management. So, without further ado, here’s my critique:

 

There was a comfortable finality in the way the old C/SCSC documents were written.  DoD 7000.02, 7000.10, and DOE 2250.1D laid down the law, and that was that.  One gets the impression that the authors of those works did not care in the least if the practitioners of Earned Value Management wanted to debate the categorization of EV measurement techniques or whether or not Project Management was “primarily a matter of” planning, doing, checking, blah, blah, blah.  They simply stated what they expected of anybody wanting to do project work for them and, whaddayaknow, it worked.

Now, flash forward about 35 years, and the PMI® is trying to assemble a Practice Standard for Earned Value.  After reviewing the Exposure Working Draft, I realized that this document suffers from an ironic malady – its scope was insufficiently defined.

I have been involved since the early days, when (a leader in the EV community) was put in charge of the original outline, and we all had input pertaining to this document’s purpose.  My suggestion was that this document be written so that an amateur EV practitioner could use it to set up a valid EVMS.  Others wanted it to promote their version of “best practices,” while still others wanted it to be so broadly applicable that third-world engineers could put every last word to maximum use.  Each of these agendas was pushed to the exclusion of the others so that, by the time the first meetings on actual verbiage were held, these meetings quickly degenerated into contentious bickering bonanzas.  I was the only author to have actually generated serious output, but this output was under enormous pressure to be watered down to the point that everybody agreed with it.  With all of the competing agendas, that was impossible.

(Another key leader of the project) then elected to employ a “ghost writer” to do the entire document, and the Exposure Working Draft is that document.  However, it’s plain to me that we still have not settled the question of purpose.  Why are we doing this?  The impression I get from reading the Exposure Working Draft is that we are still mired in the mode of writing to avoid the maximum amount of criticism and, if that’s the case, it is going to be impossible to produce a product that meets my expectations.

For example, the tone of the syntax is in instant MEGO flavor (P.J. O’Rourke coined that acronym, for “My Eyes Glaze Over”).  Most of the sentences are in the weak passive voice and, even when this document musters enough energy to strongly assert anything, it only rises to the level of eat-your-peas hectoring.  Paragraph 1.2 commits the error of “showing machinery,” which would get the author an “F” grade if it were part of a sophomore English paper at UNM.  But the “showing machinery” error does reveal an interesting influence:  the author(s) anticipated a tsunami of criticisms, and wrote in such a way as to attempt to internally self-justify.  That explains why you get such constructions as “Project Management is primarily a matter of …” all over the document (emphasis mine).

This brings us to the matter of conceptualization.  In the version that I wrote, I stated directly that Project Management and Asset Management were different, how they were different, and what tools applied to each.  I also stated rather directly that Project Control is to Project Management what bookkeeping is to accounting – in short, I furthered a highly structured conceptual model, and described what EV did within that framework.  No such framework appears in this Exposure Working Draft.  As such, EV appears to meander from being the answer to questions about project performance to being a resource management tool (it isn’t).  The lack of a structured conceptual design is best revealed by this author’s predilection for driving the story by asking rhetorical questions, and then asserting that EV is the answer to these questions.

I’ll stop being a curmudgeon long enough to address your original question, on which strategy to use in this process.  I like (the senior management team) way too much to just throw up my hands and say “It’s a bad document, and I’m sick of trying to make it better.”  On the other hand, I am getting tired of trying to weed out the personal agendas of some of the people who appear to have a lot of influence over this document.  At this point, I think we’d be lucky to get rid of some of the more egregious assertions in the Practice Standard (page 7, 3rd paragraph – EVM does NOT “require” a basis of estimate with resources at the line-item level.  It can be performed with time-phased straight dollars) and replace them with the right answer.  If we get enough comments from the others on the team, and they all appear to head in the same direction, we could probably make a case for a little more broad modifications.

But I doubt we will ever be able to introduce the elements that would make this a truly usable document – and that’s a shame.

I see egos and politics becoming more and more of a stumbling block for projects. Both result in fear of conflict and/ or challenge. Watered down, non-specific direction is in reality barely useful. I miss the days of honesty and stating facts as they really exist, and then dealing with challenges and conflicts as they present themselves.

Sorry but MEGO trying to understand the issue at hand.

Wasn't it Harold Kerzner that said, "If you don't use EV then you are just playing at project management". If not, I apologize. EV is a tool and only a tool. It's the skilled, experienced PM who can use to really understand what HAS taken place so they can make sure what WILL take place is better executed. It is a point in time project review of how your team as well as yourself have done to date. Too often EV is a club of Dilbert managers to demean those working on the project. Quit taking the EV results personally but learn vlaueable lessons from EV. EV manages even those items you don't have time to manage. I only wish EV had the credability in upper management and they understood what it truly says about current state in a project.

To the question though of how to present a standard practice, might I suggest it needs no introduction. Everyone worth their PM salt knows it to be a calculation. Just math. It's when people add organizational distinctiveness to the EV process that causes difficulty. I suggest, keep it simple, keep it pure. As Joe Friday said, "Just the facts ma'am". We PM's can learn a thing or two from Joe Friday.

Well said Harold.

"EV is a tool and only a tool. It's the skilled, experienced PM who can use to really understand what HAS taken place so they can make sure what WILL take place is better executed."

It is of equal importance for the PM to know the math part of it, at least the concept, to ensure that the interpretation of the data is of high quality.

Kerzner''s quote reminds me of Abraham Maslow''s famous expression: If the only tool you have is a hammer, the whole world looks like a tool.

I''ve been a PM since 1983 and have managed many projects that did not involve earned value.

In some cases, they involved either taking over some mess someone created and producing something worthwhile for the project sponsor. When I''m told to clean up someone else''s project mess, I usually tell the project sponsor, "I''ll tell you what I need; you get the resources".

In other cases, I''ve been told, "Take Sam, Jerry, Jeannie and do (whatever) by ________________" The longest project of this type involved disestablishing a directorate in a headquarters in Maryland, disposing of no longer needed items, packing needed items using the boxes provided by the logistics staff, creating receipts, supervising the movers loading the items on the trucks chartered by the logistics staff, cleaning the office bays, turning in the keys, walking out the door and reporting all actions completed. No money involved (people were already paid for by overhead, supplies and transportation provided) so no earned value involved with that project. I can assure you a 19 month effort required classic project management regardless of Kerzner''s outlook.

In the last eight years, I''ve seen many people screeching when something in their earned value calculations shows a problem, normally going straight to managers. Each time, I''ve asked one question: "What does the tracking Gantt chart for that project tell you, especially regarding dependencies?" I can''t count how many blank looks I've received to that question. (Maybe your project has EV problems because an external dependency impacted your project such test equipment was not available when it was scheduled because some other project "borrowed" or diverted it. I had the latter situation happen to me in 2007 on the very first day testing was scheduled to begin.) And of course there''s always the EV problem that someone thought Rosie Scenario would be involved, so their lousy estimates failed which then creates bad results in EV calculations. (If you estimate 2000 manhours to create a software application and you forgot the test and bug fix phases, your EV will probably be screwed up due to a bad estimate.) Another issue I see the estimators and EV wizards forget about is how much time will elapse between when you order an item, the item is purchased, the vendor ships it, the item is received on your loading dock, the item is inspected and moved to wherever it will be installed. If any of those "dominoes" doesn't fall exactly right on your schedule or doesn't even appear on it, what does that do to your EV calculations? All that time affects your project''s cost, but I rarely see people accounting for what it costs.

Great discussion, but I''m going to have to disagree.

Harold and Wai Mun -- "EV is a tool and only a tool" is true, much as "Vision is only one of the senses that airline pilots use" is true. Yeah, there are a variety of senses, just as there are a variety of management information tools. But if you're not using Earned Value, you're not doing project management. I would further argue that all PMs "do" Earned Value, whether they know it or not. If you are responsible for, say, a Control Account, and your accountant just announced to you that you are half-spent, what's the first thought that jumps into your mind? Isn't it, "Am I half done?" And, just like that, you''ve "done" Earned Value.


Also, I'm not following Patrick''s objections. Critical Path Methodology''s formulas are very similar to EVM''s, since their common dependent variable is the percent complete estimate. Also, the example of using 2000 manhours to create a software app supports the EVM position more than detracts ... let's take it a bit further. The original estimate is for 2000 manhours, over, say, 4 months. At the end of Month 2, the accountant informs you that you've burned 1000 manhours -- right where you should be, right? But then the (dreaded) Earned Value analysis reveals that you're only 35% done. Using the most common EV method for calculating Estimate at Completion, the savvy PM now knows (a) the original estimate was flawed, and (b) the most likely at-completion figure is 2,857 manhours. The EV analysis retains its ability to produce valid, accurate, and timely management information, even with the poor initial estimate. Also, this management information tidbit is unavailable from other MIS streams, at least at that level of accuracy.

Of course, people can and do misunderstand and misuse virtually all management information streams, and EV is no exception. But you don't see people proposing that GAAP should be eschewed, just because the use of the term "bottom line" has morphed way past its original denotation as a data bit that comes from a profit-and-loss statement.

But, hey, keep it coming.

My first point is an EV calculation's results do not necessarily tell you WHY something is amiss.

For example: SV = EV - PV does not tell you why the schedule variance, if any, occurred. It's a math formula, nothing more, nothing less.

Most people I have encountered in the last ten years who were showing EV results to management never bothered to also display the tracking Gantt chart which explains why a schedule variance occurs. In short, they told part of the story; not the whole story.
