What is agile architecture anyway? The red pill and the blue pill

Posted on Posted in Agile, Domain driven design, microservices, Software architecture

Having coached many teams, projects and organizations on both software architecture and agile, one of the questions I’ve been asked a lot over the past fifteen years is: what is agile architecture?  Unfortunately, there is no easy answer to this question. There is no simple truth out there. What agile architecture really is considered to […]

Microservices. The good, the bad and the ugly

Posted on 4 CommentsPosted in Application Migration, Client /server, Domain driven design, Enterprise architecture, Frameworks, Hibernate / nHibernate, Java, microservices, Service oriented architecture, Software architecture, Unit testing, Value objects

Back in 1988, when I was first employed by a company for writing software, the world was fairly simple. The development environment we had was character-based, the database was integrated and traversed with cursors, and we built a whole new administrative system covering everything but the kitchen sink. It took us five years to complete […]

Agile anti-patterns. Yes you agile projects can and will fail too

Posted on Posted in Agile, Kanban, Lean, Requirements, Scrum, Smart, Smart use cases, Software architecture, Software estimation, User stories

Over the years I have noticed a lot of agile anti-patterns during projects. Wrongly used agile approaches, dogmatic use of agile approaches, agile-in-name-only. Recently I have presented a talk at a number of agile and software development conferences that demonstrates patterns of agile misuse. These conferences include Agile Open Holland (Dieren), Camp Digital (Manchester), GIDS […]
