Choose a course of action confidently, even with incomplete information or time pressure.
Decision making is the process of selecting a course of action from multiple alternatives, based on available information, judgment, and priorities. In engineering, this ranges from small choices (which library to use) to significant ones (whether to rewrite or patch a system).
Collecting just enough relevant information to decide, without stalling in endless research.
Weighing a small number of realistic alternatives against clear criteria.
Actually choosing and moving forward instead of staying stuck in analysis.
Taking responsibility for a decision's result and adjusting course if it turns out wrong.
Three days before a hackathon deadline, your team's core feature was not working reliably, and you had to decide whether to keep debugging or pivot to a simpler backup idea.
You set a two-hour hard limit to fix the core issue, and when it was not resolved in time, you committed fully to the backup idea rather than splitting effort, which let the team ship a smaller but working product instead of nothing.
