Software architecture and design
Software engineering has its share of tempting absolutes: ship as quickly as possible, accommodate every requirement, prevent every failure. Pursuing them blindly can take a project away from the problem it set out to solve.
The art of software engineering lies in finding the right balance between science and business for the circumstances at hand. These essays explore that judgement: how much to build, where flexibility earns its keep, and how to make reliability serve the people who depend on it.
1. First, Solve the Actual Problem
Two teams set out to kill a house fly. One delivers a stick; the other designs a tank. Neither gives much thought to whether someone could actually use the result. A short fable about how both haste and elaborate design can lose sight of the purpose of the work.
2. Give Your Software a Point of View
Solving problems elegantly means making decisions. When those decisions come from a deep understanding of the domain, they spare both engineers and users the burden of assembling a solution from endless possibilities. But strong opinions need something to stand on; some domains demand more flexibility than others.
3. Decide What Reliable Enough Means
That same judgement applies once the software is running. Chasing a flawless record can discourage experimentation and drive valuable evidence of failure underground. User-centred reliability targets, error budgets and blameless learning give teams a practical way to decide when to move forward, when to strengthen the system, and how to recover when things go wrong.
