Explore the critical role of decision-making in software engineering through this 57-minute conference talk from NDC Sydney 2024. Delve into the complexities of building systems and learn why decisions, rather than specific technologies, are the key factors in a system's success or failure. Examine how to structure decisions and their impact on software development. Discover techniques for debugging your thought process, placing breakpoints to inspect assumptions, and considering alternative options. Gain insights into developing a more structured and streamlined approach to decision-making, leading to better-balanced choices. Learn how critical thinking can transform the decision-making process and ultimately improve the quality of solutions built for users.
