Decision-making style organizes authority, participation, and responsibility when choosing among alternatives. It strongly affects software design and should be considered early because decisions have sociotechnical effects. section 9.2
Two contrasting styles clarify who decides and how much influence others receive:
- Autocratic decision-making places control and responsibility with one person. Others are not consulted, or receive only minimal consultation, creating a strongly top-down process. section 9.2.1
- Democratic decision-making has one formal decision-maker who defers decision rights to a group, allowing the group to decide together. section 9.2.1
- Match the decision-making style with the communication style so people understand their roles and influence; mismatches create confusion, frustration, resistance, and conflict. section 9.2.1
Architect-led design
An architect makes all architectural design decisions and hands them to the development team for implementation. This illustrates autocratic decision-making: authority remains concentrated rather than being delegated to a larger group. section 9.2.1
