How do you design a large system? The architecture of any system is crucial to its success – get this wrong, an the project may never recover. And yet, we are expected to deliver designs that last 5, 10, sometimes 30 years into an unknowable future.

Problem Space Analysis is a technique that informs and documents system designs by anticipating and defining the variabilities of an evolving, long-lived system. It informs the architectural design so that it can accommodate those changes, and it delivers a change-tolerant pervasive language to unify and coordinate the development effort.

In this session, Jules will introduce the principles of Problem Space Analysis, and will show how those principles can be translated into architectures and thence into working systems, even while the goalposts are moving.
