At the start, a projects solution space is large. Anything is still possible. Few things have been decided. But during the briefing process, the client will start to take decisions about the building (concerning its location, its size, its spaces, its fit-out, etc.), and with each decision, the solution spaces gets smaller. This is a delicate process in the sense that too many decisions will limit the design teams ability to come up with good design solutions. Too few decisions, however, will leave the design team without direction.
