Who makes Architectural Decisions?

Thursday 3:20pm - 3:50pm, ITP Conference (Room 1 (Designertech))

Whilst it may seem obvious that the Architect makes Architectural Decisions, anyone working on IT projects will realise that there are many types of decisions.

There are project decisions, decisions involving the business requirements, architectural decisions, and solution design decisions. There should be a clear demarcation between each of these categories, and thus who is responsible for making the decision, but in real-life situations it can often become quite confused.

This talk will attempt to clarify these different types of decisions, with a focus on architectural decisions; how they should be documented and resolved to the satisfaction of the IT team. he heuristics and cognitive biases around decision-making will also be discussed, as rational decision-making is important for getting it right.

The benefit of correct decision-making is a higher likelihood of success for the project.
