The Architecture of Uncertainty | KEVLIN HENNEY

Creating software architecture in a world of change, uncertainty and incomplete knowledge

Ralph Johnson defined architecture as “the decisions that you wish you could get right early in a project, but that you are not necessarily more likely to get them right than any other”. Given our inability to tell the future how can we design effectively for it? Much project management thinking is based on the elimination of uncertainty, and advice on software architecture and guidance for future-proofing code often revolves around adding complexity to embrace uncertainty. In most cases, this is exactly the opposite path to the one that should be taken.

During the day we will look at how uncertainty is an intrinsic part of software development and that responding to change calls for attention to detail, a good view of the big picture and a willingness to experiment. Rather than being a problem in development, uncertainty, lack of knowledge and options can be used to partition and structure the code in a system.
