Given my (well-known and enduring) interest in all aspects of services, I have followed Martin Fowler's writing on microservices. But I will admit I always found the original paper more confusing than insightful. And in my client work I have resisted the temptation to use a microservices pattern, for precisely the reason that it would more than likely confuse. So I was interested to see the book Building Microservices by Sam Newman published last month, particularly as Newman is part of the Thoughtworks stable, which presumably means it is authoritative. Right off the bat, Newman advises that we should "think of microservices as a specific approach for SOA in the same way that XP or Scrum are specific approaches for Agile Software development". These analogies are very interesting because my expectation was that microservices is a pattern. So I might infer that micr... (more)

Agile Adoption Failure By @DavidSprott | @DevOpsSummit [#DevOps]

Understanding Agile Adoption Failure The most common concern our customers voiced in 2014 was the unexpected outcomes of Agile projects. They don't talk about failure as such. But they do talk about loss of consistency; inability to govern; lack of coordination and the increasing time-to-market caused by these precise issues. I was struck by the results of the Agile Adoption Experiences Survey 2014 published by Scott Ambler. The really significant result to me is that 40% of respondents rates their organizations adoption of Agile as neither a success or a failure. Add to this the... (more)

Service Factory as a Service (SFaaS)

The service factory concept has been in vogue for some time. As long ago as July 1989 the Harvard Business Review published a seminal article by Chase and Garvin titled The Service Factory[i]. They argued that "The factory of the future is not a place where computers, robots, and flexible machines do the drudge work . . . the next generation, then, will compete by bundling services with products, anticipating and responding to a truly comprehensive range of customer needs." In this paper we explore the concept of the Service Factory as a Service (SFaaS) which provisions softwar... (more)

Business Design for the Service-Oriented Enterprise

The way we design business is undergoing profound transformation. For the past 100 years business design has been directly influenced by Frederick Taylor, focused on how we do work and how we can make it more efficient. The LEAN and Six Sigma movements are the visible manifestation of that thinking. Together with BPM they have focused on incremental improvements of primarily internal processes and tasks encoded in process orchestration and workflows that control how the enterprise works. But this is equivalent to looking in the rear view mirror to design tomorrows business. In t... (more)

Transformation to Agile IT Delivery

The number one IT issue for all enterprises today is delivery - responding to business demand for change in ever faster timescales, at lower cost. But in the typical large enterprise, IT is widely perceived to be incapable of responding in a reasonable timeframe and cost. There are many, many reasons for this. Existing application portfolios are frequently a complete mess typically resulting from continual compromises made in order to deliver rapid business change, which commonly result in duplication, inconsistency and increased dependencies. Enterprise architecture typically fa... (more)
