Over the past few months I have been on a journey to deepen my understanding of the term "service," and to test for some level of consensus among a number of interested parties. The unclear semantics of "service," "IT service,"... Continue reading

Agree that a the idea of a unified queue has to cope with operational realities - varied granularities have to be accomodated - but while a project per se is larger grained than an incident, the project decomposes into deliverables, work orders, issues, risks, etc which *are* roughly comparable in granularity.

All, here is an excellent paper: What I find interesting is the emphasis on science. "Relying on common sense to make such decisions is unreliable, as the effects of graphic design choices are often counterintuitive." Moody here is criticizing... Continue reading

More - what are the historical roots of "digital"? I haven't looked into that. But it all starts with the etymology from my perspective, that's how I understand semantics.

I don't know that I would privilege IT over other functional areas even today. Nothing takes place outside of a legal model for doing so. We are like fish in an ocean for the most part with our lack of awareness of legal frameworks but even the basics of mercantile exchange rely on a carefully specified set of laws which at the end of the day can invoke the coercive authority of the state. I also am not sure the HR professionals would agree that they are outmoded either. I can still think of business models that don't need much if any IT. See today's post from Gartner's Richard Gorton. Some of this shades into my post What is IT Value ( Every functional area needs to focus on outcomes. If it doesn't, it's a cancer. But exactly HOW does this great tradition of IT do so? To restate - IT Value is found in qualifying the organization to participate in information-rich, transactional environments, and -- to the extent that performance depends on excellence in managing information -- in elevating this performance above peers. At the end of the day I am not ready to abandon a word like "information" with its rich context. That's always the temptation - term "x" has acquired too much baggage, so let's give in to the fashion show and throw it out. The trouble is that the fashion show never ends and we continually have to then "refresh" the language, which I think erodes not enhances social utility. I'd rather focus on improving the clarity of usage and keep terms like "information" front and center so we retain line of sight back to our origins.

Also see where this also was said 4 years ago.
Thanks Jez. The thought process was a familiar one for me: simple - complex - simple. I tend to agree with you on the change size issue, as noted above due to fundamental limits of complexity, but Majid's line of inquiry remains interesting. I really hope sooner or later someone is able to validate these hypotheses through process mining from actual ITSM, ALM, or kanban suites. I think there is a real deficit of such research in the industry.

Peter, you anarchist. Next thing you'll be saying that knowledge is socially constructed. Chris... I guess I wind up going philosophical. Agree that shared meaning is essential. As a data architect, have spent many hours driving diverse stakeholders towards just that end. But what is "true meaning" and who determines it?

Of course, entrepreneurs are often bounded by limited resources. Should have noted that. This blog is a first draft.
