New Year, New Thinking?

2010 is over and 2011 has arrived. We’ve all returned to work ready to push on with our commitments – but can we honestly say that we are producing better software now than we were at the beginning of the millennium?

In another great article from InfoQ, two seasoned IT professionals – Bruce Laidlaw and Michael Poulin – each with more than 30 years of experience, have compared their conclusions about the past and present of IT, focusing on what we are doing to make progress.

It’s a very pro-agile article and they do cover a lot of ground. However, it’s interesting when discussing certain aspects of agile methodologies they argue that…

“[The] Majority of agile methods are based on assumption that business cannot and will not work differently tomorrow than it does today; these methods do not challenge the way business works even if this way is contra-productive for the enterprise.”

I genuinely love agile projects, but its fair to say that on some agile projects in the past I’ve also been in the situation that they describe in their article where an agile development process fails to adequately deliver non-functional requirements adequately due to a preference to deliver perceived business requirements…

“It’s not a rare situation where agile teams promise to add an error handling mechanism, escalations, notifications/alerts, compensation logic, transactional integrity, security and operational stability “later on”.

All these technical things are Quality of Service (QoS) attributes that the business expects from the technology by default, not ‘next time’ or as a special additional feature.

The article is a pretty convincing argument for a new kind of approach to enterprise software development where business architecture, technical architecture and governance discipline combine to  ‘build-in’ quality and agility from the start, something that many modern developments often lack .
