“Last year the decision was finally made to mandate Agile across our enterprise. The decision was taken, even though there were many unanswered questions. The assumption was that forcing the migration, along with adoption of popular “enterprise Agile methods” would ensure resolution of the outstanding questions. In practice, Agile methods have been very effective in delivering specific digital business initiatives. But almost inevitably the distribution and delegation of architecture has resulted in duplication, inconsistency and increased complexity, across all project types including legacy and new projects. We are now concerned that we no longer have an effective governance capability. The question is how do we fix this without losing the undoubted benefits of Agile methods?“ Enterprise Architect, F2000 company. Over the past few months I have heard this message ... (more)

Microservices Unplugged | @DevOpsSummit #IoT #DevOps #CD #Microservices

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.

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.

But this is equivalent to looking in the rear view mirror to design tomorrows business. In t... (more)

Agile Architecture

The English language is well known for its subtlety. Sometimes it’s a delight, but on other occasions it can be very frustrating. If I use the term Gothic Architecture you will immediately understand I am describing a style of architecture that flourished in medieval times. And if like me you are interested in ecclesiastical architecture you will know that this style was used in many of the great cathedrals and churches across Europe, which were distinctive because of key architectural patterns that enabled great increases in height and internal light of the buildings without inc...

Understanding Business Services 2

In December 2006 I blogged on the topic of Explaining SOA to the Business Audience. It started out "I note resurgent interest in LegoTM blocks as a metaphor for explaining to the business audience the value of SOA. My advice is don't treat the business audience as dummies!" The blog goes on to explain business services using the Laundry metaphor, and how business people get the concept because they understand "services". However, while my explanation was and remains perfectly okay, I will be the first to admit that I have moved on. The basic service model works perfectly, but in... (more)
