Architecture & Design

Are You a Software Architect?

The line between development and architecture is tricky. Some say it's fake, that architecture is an extension of the design process undertaken by developers; others say it's a chasm that can only be crossed by lofty developers who believe you must abstract your abstractions and not worry about implementation details. There's a balance in the middle, but how do you move from one to the other?

Using ITIL V3 as a Foundation for SOA Governance

Those familiar with only ITIL V2 often scoff at the thought that ITIL could serve as a governance framework for SOA. Based on their perspective, they would be correct since V2 focused more heavily on operational processes rather than service lifecycle. With ITIL V3, the focus of the framework shifted toward what can only be accurately described as service-orientation.

Agile and SOA, Hand in Glove?

Agile is the hand that works in the glove. SOA is the glove, the scope is enterprise wide. Most principles of SOA and Agile are not in conflict. When they are, they keep each other sane. Agile development without a clear vision of the goals and objectives of the company is futile. SOA without a clear vision how to make it real using agile development principles is a waste of time and money.

The Meme Lifecycle

Julian Everett and Chris Matts describe an IT business case as a meme - one that is competing in the complex ecosystem that constitutes a market sector and show its implications. By taking this view of a business then an organization's short and long term strategies change and we get a completely different view of how and why current development practices exist and persist.

Agile Teamwork: The Leadership - Self-management Dilemma

Self-managed teams are unstable and are successful when the ‘Leadership – Self-Management’ dilemma is understood and dealt with. Too much central control destroys agility, inhibits creativity and resists change. Too much self-management leads to chaos and anarchy and destroys a team. A successful Agile Team operates as far along self-management as it can, without tipping over into chaos.
