A decision is a conscious choice between two or more alternatives that irrevocably allocates resources such as time, money, or energy. It is an actional process rather than an automatic habit: someone must think, choose, and commit resources whose loss makes being wrong costly. section 9.1.1
A decision becomes clearer when you identify its working parts:
- Alternatives are distinct plans: sets of intended actions aimed at a desired outcome. section 9.1.1
- Information changes uncertainty and confidence; preferences help evaluate the available alternatives, but framing can influence those preferences. section 9.7
- A clear problem statement establishes what the decision must address, while logic derives a course of action at a depth suited to its complexity. section 9.7
- A designated decision-maker needs authority to allocate resources, even when the surrounding process is collaborative. section 9.7
A resolution becomes a decision
Declaring a New Year’s resolution does not necessarily create a decision. If someone never invests time, money, or energy in going to the gym or starting to swim, no irrevocable allocation has occurred. Commitment begins when the chosen plan receives resources and changing course carries a cost. section 9.1.1
In collaborative software design, decisions should be judged by the quality of the initial context and analysis, not only by the eventual outcome. Sustainable solutions require many smaller decisions that account for sociotechnical effects, suitable decision-making styles, buy-in, and conflict. Formalize chosen alternatives and consequences, communicate them, then keep them open to feedback and revision. section 9.7 section 11.1 section 11.3
