The following section is from my forthcoming book, about midway through. This book is pivoting to be a fully realized academic textbook on Agile IT Management, from startup to enterprise. I work at a teaching university instructing a diverse student... Continue reading

Yes exactly

Hm link appears broken. But why limit the # of modes? That's the point of parametric.

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

I’ve been working with Vagrant over the past few months, and recently started investigating Docker hands-on in my lab. Both container technologies are impressive and useful and are changing the face of application delivery. But I have questions about licensing... 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

Still polishing, but my new course description will look something like this: SEIS 660 Information Technology Infrastructure This course covers the engineering and operation of IT infrastructure, and related IT management practices in both theory and practice. Students participate in... Continue reading

Part II of the series, "Architecture, Agile, and personal re-invention" As I discussed in my previous post, I've taken the DevOps challenge to heart and am going to gemba to understand it better. This has required an intensive round of... Continue reading

Thanks Mark. There was some chatter that Pat Debois and others wanted to treat the Wikipedia page as normative, but I don't know where that went. I like Gene's definition but wish it mentioned feedback.
Part I of a new series, "Architecture, Agile, and personal re-invention" Architects and analysts have a lot in common, and I've been some combination of both for quite a while. We deal in abstractions, because we have no choice –... Continue reading

Absolutely. Currently Calavera supports just unit testing but my intention is to expand it to integration and performance testing.

Hi Simon, I have not completely thought through that side of things, but it will doubtless involve some of what Troy Magennis has explored (see his book on Amazon) with Monte Carlo and Kanban. Charlie

The "IT vs Business" meme is popping up on Twitter again. I've covered this here and here, but let's just recap: 1. Humans have always depended on tools and technologies. Therefore the use of technology is inextricably intertwined with what... Continue reading

Thanks Eric. I recognize that many are absorbed with the cultural aspects of DevOps, and that's not a domain I have as much to say about. Although it's interesting watching the students self-organize into teams and how their experiences mirror mine in large enterprise organizations. Perhaps I'll have enough insights eventually on that front to contribute something. Tying functions to DevOps is something that I have touched on in the book and also have worked on in the IT4IT standard - more on that forthcoming. The most interesting thing for me is that we can see a DevOps pipeline as a sort of microkernel of IT delivery. By building on that, my hope is we can gain a better, more grounded understanding of more abstract IT management concepts.

I'm familiar with the idea of pace layering in general (multi-speed) but am wondering if there are any detailed treatments of it. Reinertsen suggests that cadences can be harmonic multiples, which would be one technique for achieving coordination across the layers.

Thanks Dave - sent to you. SAFe (Leffingwell) is definitely a key player here although controversial in the Agile community. It's one of the few manifestations of Agile that recognizes the need for EA. I hope to see some of the SAFe folks next week at the Lean Systems conference in Nashville.

Thanks Anders. Yes, I tend to see solution architecture as scoped to one system. Perhaps this is an overly limiting view. However, my points apply to the higher level EA views - capability, data, value chain, etc.
