Beware the Cookbook Approach! We hear this, but what does it mean? Usually, it means the mistake of thinking something complicated can be reduced down to a simple set of steps, like a recipe in a cookbook. I've heard people... Continue reading

Yes, Peter, I was careful to state that "there are also elements of product management." One thing I will be writing up sooner or later is ITIL's limitations in this regard. It was written seemingly in a parallel universe to the rich body of knowledge and active practitioner community that is mainstream digital product management. At least half of the Agile world's discussions revolve around product management, grounded in the thinking of Blank, Cagan, Ries, Gothelf, and others. ITIL is not part of that discussion, which centers on the iterative, experimental "discovery" of customers and value. Instead, ITIL proposed that market spaces / service spaces be derived analytically, an idea that has fundamental conceptual problems. (See: Cynefin.) As you tacitly admit, ITIL is structured in a way that positions it as process-focused. I think every one of its processes has defined KPIs, CSFs, inputs, outputs, and interfaces. But that was the discussion at the time. I recently came across this quote from Jan van Bon, when he edited the 2002 Guide to IT Service Management, a survey of 15 frameworks: "All the frameworks provided for designing IT Service Management adopt a process-oriented approach. Function-oriented and organization-oriented approaches have quite definitely had their day. The focus is on the customer, and there is the general belief that to pursue that principle efficiently a process-oriented approach has to be adopted." Well, that didn't work out, because there was too much transactional friction in the process-centric approach, it implied a factory model of work being routed between centers (otherwise why the I/O?), and it was corrosive of high-performing team cohesion. I'm not like some who just want to blow stuff up. I really do want to handle this as a question of evolution. But we have to be clear about the state of affairs and what was really achieved in frameworks like ITIL and PMBOK.

Yes, no argument there - that is why I prioritized a chapter on product management, which has not to date been a major topic of attention in IT education. Do you see a meaningful distinction between "services" and "products"? I don't...

hi Joe, I do think we can expect more from the frameworks. There is well-grounded knowledge covering these issues of throughput and flow. It can and should be incorporated into the frameworks and would make them more fit for purpose. I am trying to do just this with IT4IT. The thought leaders behind Kanban and SAFe are doing the same. Charlie

Hi Valerie, It's interesting - yes, we do have to have SOME kind of process in order to measure throughput. But in general, it's a process (like Kanban, or Case Management) that operates at a higher level of abstraction - not bogged down in dozens of checklists and procedural details, rather just tracking that there is some "thing" we are going to move through to some "definition of done."

Thanks! Yes, there are many improvements needed. My top priorities right now are switching to Docker and selecting an optimal Web programming framework, which will then drive the testing. Part of my problem is that my class is very, very broad, going from hands on in the first half to higher order management in the second half, so I have limited time to go into detail. You might be interested in my open source textbook - Regards, Charlie

Bernard Golden has some good thoughts on bi-modal IT . My view is summarized in this picture: By my reading, there is nothing in current Agile theories (especially Reinertsen) supporting the hypothesis of bi-modal IT. We need parametric IT, not... Continue reading

interesting - thanks Ivor
Thanks Michael. I see my work as input for the standards community. My intention is to identify new constructs and ways of thinking, as hypotheses for validation. When and if evidence supports them, then they may be appropriate for standards. Reinertsen takes a skeptical look at Critical Chain in Principles of Product Development Flow, and I think provides better general-case thinking of how to approach the scheduling problem. regards ctb
