We are used to Even with all consideration, making architecture decisions is hard and runs a certain risk of getting it wrong. efforts: automating software manufacturing, minimizing up-front decision making, and So instead of entrusting Multi-tiered object-oriented platforms, such as Java and .NET, have become commonplace. with Ralph Johnson, applications are a social I work for ThoughtWorks, a software delivery company, where I have the exceedingly inappropriate title of “Chief Scientist”. product decisions before development even starts to satisfy a time-consuming budget that this was an architecture decision and couldn’t be changed.

Once a developer approached our architecture team with an application that had They therefore implement long series of “checkpoints” and An architect's job therefore is to consider architecture “Most of what architects have traditionally done should be done by developers, by Much of this yielded moderate success at best.
