Building software is usually a craftsmanship task. Software can be engineered, but It’s rare and expensive so it’s only built that way when the cost is justified, as when building life critical systems (manned aircraft/spacecraft flight controllers) or security critical components like ssl stacks, cryptographic algorithm implementations, etc.
