Another Management Trope Blown To Smithereens

 

Have you ever been in a situation where your employer has requested/directed/demanded that you put in extra hours, but upon putting in the extra time, no positive result was observed? The notion that organizations perform best when their Return on Investment figures go up is a core concept in business models everywhere, so I suppose it falls to me to show how it’s highly suspect at best, counterproductive often, and has no place in the realm of reflexive management tactics.

The error falls into two categories, one from our friends, the Asset Managers, and the other from a popular but, in my opinion, intellectually vacuous novel based on a derivative of a well-known and established PM technique. First, the ability of Critical Path Methodology (CPM) software to correctly identify which activities are directly responsible for potential late scope completion, as well as the organizations performing those activities, has to be one of the most powerful pieces of management information that PM-centric systems can generate. Management time and energy is finite. The ability to know which parts of the project and team that are doing just fine without managerial input and those that need direct attention is huge, and can go a long way towards optimizing PM’s time. However, this information is only available from CPM-capable systems, and not from the Asset Managers’ main tool, the general ledger. It follows, then, that Asset Management-based solutions do not work on Project Management-oriented problems, like overcoming a potential late project delivery date, or milestone. The unfortunate put-upon staff from the question in the first paragraph getting called in to work may have done absolutely nothing to help the project get back on-time, but somehow the notion that these resources were “working” without incurring any additional marginal costs (assuming they were all on salary) makes this demand seem somehow legitimate. In reality it takes a wrecking ball to morale; but, since morale can’t be quantified, this error is rarely criticized or condemned.

The second error category that pertains to this blunder has to do with a work of fiction from 1997, entitled Critical Chain, by Eliyahu Goldratt. In the novel, the protagonist manages to make progress towards schedule goals by using a technique that seasoned schedulers would instantly recognize as “crashing the schedule.” Crashing the schedule involves assigning more resources to critical activities – particularly ones that are in or may become trouble – in a bid to accomplish the scope more quickly.

There are several attendant problems with crashing the schedule beyond increased costs or the possibility that the increased resource density could actually decrease productivity, but the main issue with the tactic has to do with an assumed commonality of expertise. If, say, your electricians look like they won’t finish on-time, it really doesn’t do any good to call in the cement pourers. In the example above, the people being called-in to work needless overtime didn’t necessarily improve schedule performance. These problems with the push-staff-harder approach, however, did not stand in the way of the rebranding of crashing the schedule as “critical chain” management becoming something of a sensation in PM circles. There’s even a Goldratt Institute, which probably owes no small part of its existence to the success of the 1997 book. But that’s kind of the thing with PM theories that may or may not work so well in the real world: they can always, always be made to work in the world of fiction. It’s highly reminiscent of B. F. Skinner’s 1948 novel Walden Two, where his then-nascent theories of behaviorism are used to govern a small but extraordinarily well-ordered society, where virtually the entire population is happy and performing at near-peak potential fulfillment levels. Behaviorism would go on to become a major school of psychological thought before finally receding in popularity during the “cognitive revolution.”[i] While asserting that, as a psychological trope, it was blown to smithereens may be a bit excessive, I would go so far as to say that any near-science hypothesis – like those belonging to psychology or the management sciences – that achieves widespread acceptance not through experimentation and the publishing of results, but via fiction, is fully deserving of higher scrutiny, if not reflexive abandonment.

As for the notion that automatically pushing staff to work harder whenever a schedule setback is encountered, yeah, that’s one management trope that should be blown to smithereens.
