Game Theory in Management

While on vacation in northern New Mexico, my wife, younger son, and I walked into an art gallery in Arroyo Seco, and almost immediately I saw a piece that I found fascinating. It was a landscape of what could be a southwest United States town at dusk, done with deep blues and brilliant oranges, and I was determined to have it. I don’t know, I suppose there’s just something about well-done artwork that has a calming, psyche-healing effect on people, and this piece certainly had that effect on me. I knew just where I wanted to hang it, too, on one of the longer walls in my house. When I asked the gallery owner about the piece, I mentioned that I could wish the painting was a little bit larger.

“How much larger?”

“Why?”

“We can print it out for you in almost any size you want.”

The image had been captured digitally, and, with some fairly advanced (and large) plotter/printers, the quality of the output made it indistinguishable from the original. I was surprised, but shouldn’t have been. I listen to my share of music, for example, but can think of only one time that music was produced from a non-digital source, and that was only after having run into an old friend of mine whose dad had run an audio store in the 1970s, who really wanted me to hear a recently-purchased vinyl album.

Of course, the movie industry has been profoundly changed by digital transformation (ProjectManagement.com’s theme for February). The movie Titanic, featuring a digital version of the titular ship, cost more to make than the costs associated with the original’s loss (excluding the lives lost, of course). Also consider that, according to Wikipedia, George Lucas makes an appearance as the director of one of the fifty most successful movies of all time (Star Wars: Episode 1, The Phantom Menace, at #42[i]). Lucas is probably most famous for his seminal work in introducing large amounts of Computer-Generated Imagery, or CGI, into his work. However, Alfred Hitchcock has two entries in the top fifty “best” movies, according to the IMDB (Vertigo at #11, and Psycho at #12[ii]), neither of which (obviously) had any CGI whatsoever, while Lucas does not appear on the IMDB list at all. I believe a reasonable inference is that, while CGI has undoubtably contributed an amazing number of backgrounds, settings, devices and even characters to cinema, the actual gauge for excellence still lies with the quality of the script, the performance of the actors, and their directors’ guidance, both during shooting and in the film editing room.

Meanwhile, Back In The Project Management World…

I’ve lost count of the number of software packages that started out as PM programs that have made the attempt to become program, or even portfolio management systems. Some have pursued this capability by increasing the scale and breadth of its Work Breakdown Structure capacity, or by pulling in certain aspects of resource management (as an aside, using PM software to, say, level-load resources across activities is a legitimate PM function; trying to poach capabilities that truly belong to the General Ledger [e.g., timesheets] is not). While in many cases this expansion has advanced the abilities of Project Management Information Systems (PMISs) to both reliably predict at-completion times and costs as well as create a more reliable audit trail of PM decisions, there is scant evidence to suggest that these advances are actually helping bring more projects in on-time, on-budget. Ironically, the very projects that are most notorious for coming in late and over budget – Information Technology – are the same ones that exist square in the middle of the digital transformation phenomena. It must be stated and re-stated: a numeral is not a number, a CGI Titanic can’t actually float, and gee-whiz, sparkly “portfolio management” information systems can’t change project performance by themselves. That can only be accomplished by real-life PMs.

Before any members of GTIM Nation remind me, yes, I still hold to the Hatfield’s Incontrovertible Rule of Management (HIROM) that states that the 80^th percentile best managers with access to only 20% of the information needed to obviate a given decision will be consistently out-performed by the 20^th percentile worst managers who have 80% of the information so needed. This  HIROM, however, pertains to relevant information, not the Gaussian speculations listed in the risk register, or the Estimates at Completion derived from re-estimating the remaining work, and tacking on the actuals.

So, I’ll re-ask the question: these advances in PM coming from digital transformation – are we becoming better performers, or are we just looking better?

In the 1983 movie Mr. Mom, Michael Keaton’s character Jack Butler has been furloughed from his job as an automotive engineer, but after some time is invited to re-interview for it with his former boss and three other executives. Rather than an interview, however, the three execs demand that Jack answer for the fact that, after he had left, production in his former department dropped by 23% while expenses increased 19%. The very availability of these figures leads me to believe that Jack’s former organization had some elements of a Project Team, since had he headed a functional group (or even a purely Level-of-Effort-based Control Account or Work Package) there would have been no way of measuring precisely the drop in production. Since “production” is clearly being quantified and compared to some sort of baseline, we know that some version of a time-phased budget (the Budgeted Cost of Work Scheduled, or BCWS) exists, as well as the ability to capture performance (Earned Value, or BCWP). Of course, all registered corporations have a General Ledger, but it’s not clear from the dialogue if the Actual Costs (ACWP) are available in the PM sense of the term, since the GL would have to be set up to track costs based on a Work Breakdown Structure, as opposed to an Organizational or Functional Breakdown Structure. I believe Actual Cost collection by WBS can be safely inferred, based on the following.

Let’s assume a cumulative time-phased budget of $100K, since, for the sake of this exercise, the precise dollar amount of this parameter isn’t really relevant, as the stated data points are given in percentages. Let’s further assume that the previous production performance was acceptable, meaning that this previous Earned Value figure (cumulative) would have been roughly equal to the prior time-phased budget (cumulative). Based on a production schedule baseline of $100K, in order for “production” to have dropped by 23% against the current time-period figures, the Earned Value number would have to have been $78K, with the corresponding Cost Performance Index being 0.78. I’m going to do a little more reverse-engineering/inferring, and assume that when they said that “expenses” increased by “nineteen percent,” they meant for the same amount of production, as opposed to, say, a similar passage of time (or, if they did mean over a period of time, that their expected production rate was relatively steady). To arrive at that figure, the Actual Costs (cumulative) would have had to have been $96,296.30 (USD).

As an aside, and in further confirmation that some form of an Earned Value Management System is in place in this fictional scenario, had the performance figures been based solely on the General Ledger, the comparison of the $100,000 budget to $96, 296.30 would have yielded a positive cost variance of $3,703.70. The only way to quantify the drop in production and relative increase in expenses is by capturing the output, or production – the very essence of Earned Value.

Back to Mr. Mom. Jack’s answer to the executives, after reminding them that he doesn’t actually work for their company any longer, is to assert the glaringly obvious: the proximate cause of the poor performance experienced was the decision to furlough Jack and his two key associates. Yes, it’s all fiction, but I believe it points to a common condition in …

If the decisions facing PMs in the real world were readily reducible to formulaic responses or canned strategies, we could all be replaced by computers or robots tomorrow (though, if I am to be replaced by a machine, I would like it to have super-strength, like Lt. Commander Data from Star Trek, The Next Generation). In scenarios like those experienced by the fictional Jack Butler, if a corporation sees decreased production and increased expenses after having furloughed specific people, it signals that those people were exhibiting a high degree of resiliency (ProjectManagement.com’s theme for January) in their decision-making. It’s an unfortunate but ubiquitous aspect of Project Management that true managerial resiliency seems to only get noticed when a PM makes decisions that are inconsistent with the owning organizations’ canned strategies, and something either very good or very bad happens. Consider the following payoff grid:

My takeaway from this payoff grid is that, since the whole demonstrative management resiliency game appears to be set up to reward those who stick to familiar decision-making templates, not to those who easily adjust to adversity or change, it’s a wonder that that capacity is seen as often as it is. Also, resilient managers knows when to abandon canned strategies, and show that they can’t be easily replaced by robots.

Even Lt. Commander Data.

In the June 1952 issue of Collier’s magazine was a short story by famed Science Fiction author Ray Bradbury entitled “A Sound of Thunder.” Set in the year 2055, when time travel is available, big game hunter Eckels pays Time Safari to take him back more than 60 million years in the past in order to kill a Tyrannosaurus Rex. Travis, the guide from Time Safari, lays out some very strict rules for the hunters, including the need to stay on a levitating path that keeps the time-travelling hunters from interacting with the late Cretaceous environment. Travis points out that even the slightest change to the environment could have a cascading effect, impacting the hunting parties’ present. For those who haven’t read the story (or seen the film), SPOILER ALERT! that’s exactly what ends up happening after Eckels strays off of the path and accidentally steps on a single butterfly.

I find the use of the accidentally-killed butterfly to be fascinating, in that Edward Norton Lorenz would not describe the Chaos Theory building block, The Butterfly Effect, for another seventeen years.[i] The Butterfly Effect essentially posits that even very small perturbations within an interconnected network can have non-linear, even catastrophic impacts on the other parts of the network, often illustrated by the question “If a butterfly flaps its wings in Brazil, does it cause a hurricane in Texas?” Bradbury’s use of the butterfly image is a poignant way to offer up a treatment almost never seen in the multitude of movies and books that include time travel in their plots, namely that we really have no idea what would ensue if a particular historic variable were to be altered. Virtually all of the other works of fiction that deal with the question show the protagonists’ actions in their historic venues to have the effect of correcting a mistake in the time period from whence they came, with the theory of Unintended Consequences only making a rare appearance. It’s a deeply-held human conceit, I suppose, that we can possess a complete and comprehensive knowledge of the causal links that exists among events that occur in sequential order, and can correctly identify the impact of such decision points on their eventual outcomes.

After the newly-minted PMP® receives their certificate in the mail and has inserted it into a frame, the thought that there’s more to success in the PM world than what was taught in the certification-prep classes invariable enters their thinking. Probably the largest sector of this undiscovered country resides in the Organizational Behavior and Performance realm, which largely resembles Bizarro World from Superman. Are you encountering unreasonable resistance from Finance and Accounting to implementing even a basic Earned Value Management System? Bizarro World. Does every single Control Account Manager (CAM) insist that their work is strictly level of effort? Bizarro World.

But certainly one of the leading citizens of management’s version of Bizarro World is the representative of those holding to the idea that a complete and comprehensive knowledge of the causal links that exist among events that occur in sequential order can be correctly identified, along with the impact of such decision points on their eventual outcomes. Don’t misunderstand – I’m not knocking experience. Seasoned PMs are far more likely to make the correct decisions in an environment of incomplete information than rookies. No, it’s not the PMs I’m taking on here. It’s the Management Information Systems that are supposed to be informing those decisions. And the most common MIS used in the Project Management World that is predicated on the idea that the causal links that exist among events that occur in sequential order can be quantified and evaluated? That’s right, it’s the risk register, relentlessly pushed as essential by our old friends, the risk managers (no initial caps).

To prove my point, compare and contrast what happens during a typical risk event evaluation session with the examples available on-line, from major Universities, for calculating dependent risk. For the latter, examples usually include coin-flipping, dice-rolling, or other, limited-possible-outcome scenarios, which also have the advantage of having clearly mutually exclusive outcomes. One can’t pull anything other than a red or black playing card from a standard deck, for example.

However, in creating risk registers, subject matter experts are invited to offer up alternative events to those expected in the baselined management approach, and guess estimate both their odds of occurrence, and cost/schedule impact. These are then (usually) binned into categories pertaining to whether or not the events being considered are mutually exclusive, dependent in some way, or purely independent. But even this binning can’t be considered absolute, or even roughly reliable. Is there a risk event citing a 15% chance of increased vendor costs causing an 8% increase in budget? How can it be quantified, or even known, if this cost increase is passed along to any or all of the Project’s other suppliers? We’re not even remotely close to the type of closed systems where such calculations can be effective. Instead, the Project risk-evaluation environment far more closely resembles the levitating path for time-travelling Tyrannosaurus hunters, where the slightest change in parameters can have a cascading effect, rendering the very basis for modelling management decisions invalid.

And if accidentally stepping on a butterfly can utterly change the world, then just imagine what far more impactful things can do to just our projects.

In the Star Trek (the Original Series, or TOS) episode The Changeling, the starship Enterprise is struck by an explosive device fired from the deep-space probe Nomad in the opening scene. Nomad is apparently responsible for the deaths of over four billion inhabitants of the Malurian star system, and Science Officer Spock reports that the device that hit the Enterprise had the explosive equivalent of over 90 of their photon torpedoes. As a point of comparison, the energy yield from such a blast would be around 5,760 megatons, enough to power New York City (at its current rate of consumption) for approximately 1,677,768 years[i]. After several more hits, Captain James Kirk manages to communicate with Nomad, and discovers that it is actually a combination of an alien and Earth-originating probes. Its re-formed identity has led it to believe that it must eliminate anything it finds to be “imperfect,” primarily “biological infestations” (i.e., life) that it encounters, and it is headed to (where else?) Earth in order to carry out its twisted, horrific mission.

Of course, Captain Kirk manages to talk Nomad into destroying itself (fans of Star Trek are aware of the good captain’s talent for doing so), but before he accomplishes this we are treated to many lines of dialogue from the supposedly perfect thinking machine. One line that Nomad repeats several times is “Non sequitur. Your facts are uncoordinated.” A non-sequitur, of course, is a conclusion or statement that does not logically flow from the previous argument or statement.[ii] In other words, Nomad is alerting the speaker that they have offered up something irrelevant. The irony in this comes about when Captain Kirk informs Nomad that its belief that Kirk is actually Nomad’s creator, Jackson Roykirk, is itself in error and that, in order for Nomad to fulfill its programming, it must destroy itself. Heckuva price to pay for uttering something irrelevant, but then again Nomad was responsible for an awful lot of fictional alien deaths.

Fortunately for we PM-types in the 21^st Century, offering up irrelevancies in the name of advancing management science in general, and PM science in particular, does not result in getting hit with a 5,760-megaton explosion, or even, it would seem, any condemnation at all. But management science is not advanced by chance interactions with extremely powerful alien probes combining elements of other management types’ techniques or practices. Indeed, I would go so far as to argue that the entirety of Project Management can be summarized as the quest to deliver accurate, timely, and relevant information to the people responsible for delivering a set piece of scope on-time, and on-budget. Whether or not a certain information stream is accurate can be objectively evaluated, and whether or not it’s timely is mostly objective, with a bit of subjectivity thrown in. But relevance? That’s a whole different probe animal. What’s relevant to one manager might be entirely superfluous to another, meaning that coming up with a single litmus test for relevancy is difficult in the extreme, if not impossible.

Muddying the waters here is the dual nature of Project Management Information Systems. Their primary purpose is to put into the hands of the aforementioned responsible decision-makers what they need to bring in their projects on-time, on-budget. Unfortunately, this perfect thinking machine deep space probe perceived itself to be incomplete, and had a chance encounter with the alien notion that PMISs exist in order to provide an audit trail for third parties to come in after the project is complete and criticize decisions with which the reviewers disagree. The terrifying conflation of these two management science notions has led to a state of affairs where four billion a whole lot of small projects that would have otherwise employed simple and effective PMISs, such as Earned Value-based ones, instead eschew them, dramatically lessening the odds of these projects reaching a successful close.

Fortunately for the PM Galaxy GTIM Nation, I’m around to point out the clear logical breakdown of the notion that PMISs exist primarily as a tool for ex post facto criticisms of the Project Team; however, I haven’t observed the spontaneous self-immolation of the opposing concepts, at least not yet.

Maybe I need to hit that idea with a blast equal to ninety photon torpedoes.

When I saw ProjectManagement.com’s theme of Resiliency for the month of January, I assumed it was meant primarily to encompass human resiliency, particularly since we appear to be required to continue to operate under less-than-optimal conditions in the PM world for the foreseeable future. But harken back to one of Hatfield’s Irrefutable Rules of Management, that the 80^th percentile best managers with access to only 20% of the information needed to obviate a given decision will be consistently out-performed by the 20^th percentile managers who have access to 80% of such information. This being the case, rather than point out and encourage the human factors that make up a resilient personality, I’d like to focus on something a bit more objective: which Project Management Information Systems are more resilient, or robust than others?

We can dispense with one of my favorite targets, risk management (no initial caps) right off the bat. Besides its inability to deliver information of any relevance, it is absolutely devoid of accuracy or precision, as demonstrated by the following thought exercise. Immediately prior to the flip of a fair coin, everybody knows that the odds of its landing one side facing up is fifty-fifty. Of course, after the flip, the coin has done one or the other, raising the question “Could a more precise prediction have been made?” Perhaps, if the one doing the predicting knows, with a high degree of precision, which side of the coin was facing up at the time of the flip, how much pressure went into the flip from both the thumb and arm motion, the precise points (I mean, like in microns) of the coin that were resting on the thumb and forefinger of the flipper, air density, temperature, weight and surface area of the coin, hardness or elasticity of the surface upon which the coin lands, exact height of the hand doing the flipping, etcetera, etcetera. Note that the absence of even one of these parameters immediately returns the predictor to the 50/50 call. Naturally, none of these data points are known at the time of the coin flip, or are even knowable to the level of precision needed for a greater than 80% accuracy, which is, ironically, the level of exactness called for in the infinitely more complex exercise of establishing a project’s contingency budget. Now, all that having been said, I suppose one could make the argument that risk management (no initial caps) is highly resilient, since its output is never held to any kind of an ex post facto evaluation, along the lines that, say, anyone could have predicted a 50% chance of a fair coin flip resulting in heads.

I’m not even going to touch Communications Management, since it doesn’t deal so much with information content as much as the manner and vehicles by which said information is conveyed to the people who need it to make informed decisions. I do, however, want to spend some pixel ink on our other friends, the accountants. I do not believe that double-entry bookkeeping can be said to be resilient. I think “brittle” is a better term, based on the myriad rules and guidance that goes in to Generally Accepted Accounting Principles. If any of those rules are violated, or an incorrect amount is entered into the General Ledger, then all subsequent output is thrown off by that amount. It’s why balancing the books is so critical to the month-end closing process. A balanced General Ledger passes my three tests for valid Management Information Systems (accurate, relevant, timely), but resilient? Not so much.

“So, Michael” I can hear GTIM Nation ask, “which MISs are resilient?” Well, the one that pops to my mind is Earned Value. EV has a remarkable self-healing capability. For example, let’s say that your project’s estimator provides you with a wildly optimistic cost baseline of $100,000 (USD) over ten months, and you begin work not knowing how comically low this figure is in reality. At the end of the first month, with the time-phased portion of the work worth $10,000, and the actual costs coming in at $10,000, everything seems to be going okay, right? Except your project controls analyst is showing only 5% complete, therefore $5,000 earned. The PM could be forgiven for believing the accountant’s take that everything’s on-track, even as the project controls person is predicting an Estimate at Completion of double the original cost baseline; however, after Month 2, with cumulative budget and actual costs figures at $20,000 each, but Earned Value still lagging at $10,000, the red flag is inescapable. The original estimate was disastrously low, the project is in real trouble, and none of the other information streams could have quantified, or even predicted the problem so early in the project’s life cycle. In an epistemological sense, the EV information stream was hit by the adverse event of a poor initial estimate, yet continued to provide an essential function without a hitch.

And that, GTIM Nation, is what I call a resilient information stream.
