McCormick's IT Law of the Conservation of Effort/Complexity


McCormick's IT law of conservation of effort/complexity states:

In a closed system, i.e., a system isolated from its surroundings, the total effort/complexity of the system is conserved.  Simply automating something does not make effort or complexity disappear.  It just transforms it behind the curtain for system administrator to manage, resolve, handle.  The effort/complexity still exists in the universe, just in a different form, handled by a different SME.



-Have you heard of Murphy's Law?

-Yeah, anything that can go wrong will go wrong.

-What about Cole's Law?

-No I haven't heard of that one.

Digital Twin? Beware Naive Faith in Simplicity

Gartner analyst Marc Halpern looked a bit worried when talking about digital twins during this year’s PDT Europe conference in Gothenburg, Sweden. He voiced concerns regarding the turn things have taken.

“It really scares the heck out of me,” he said, pointing to the seemingly unfazed attitude surrounding this complex concept in the wake of the hype of recent years.

“There’s a naïveté about the possibility of bringing together digital twin concepts in terms of cost and time," Halpern claimed. Although he was positive about the basic content and thought structure, he warned the audience, “It will take longer and will be more resource-consuming than anyone can imagine to get these solutions in place.”  

It is not impossible, he added, but there are a couple of crucial factors to consider. Which are they? Halpern discussed eight success points under the headline, “Busting the Myth of Digital Twins and Planning Them Realistically”.

Against KPIs

"Contrary to common sense belief, attempts to measure productivity through performance metrics discourage initiative, innovation and risk-taking. The intelligence analysts who ultimately located Osama bin Laden worked on the problem for years. If measured at any point, the productivity of those analysts would have been zero. Month after month, their failure rate was 100 per cent, until they achieved success. From the perspective of the superiors, allowing the analysts to work on the project for years involved a high degree of risk: the investment in time might not pan out. Yet really great achievements often depend on such risks."
