Design
The practice of creating plans/specifications for the construction of an object, system, or measurable human interaction. In IT, this includes software design, infrastructure design, and service design.
Impact
Good design reduces the cost of future changes. Poor design (over-engineering or under-engineering) locks you into expensive pathways that are hard to reverse.
Weinto take
Design is about constraints. A designer who says "anything is possible" is dangerous. We practice "Domain-Driven Design" (DDD)—modeling the software to match the business language and boundaries. The code should speak the same language as the experts in the room.
