Reading: Student Q&A: Dealing with Architecture in Agile w/ Devin Hedge


This week Devin Hedge joins Dave Prior for another student question. This time about architecture and if the complexity of it would be better served by a waterfall approach:

The Question

How to plan for the Architecture effectively. With waterfall, we try to figure out all aspects of the business and the technical solution in advance before we start development. In Agile, we discover as we go. It’s very likely that when we come to a certain, we’ll find either the current business logic or the current technical framework cannot adapt our upcoming demands. There’s a high opportunity that we’ll need to destroy all the work that we’ve done. Talking in this perspective, isn’t waterfall better than Agile?
