  • Cheap Changes - Agile methods appealingly promise a drastic drop in the cost of making code changes. Utter nonsense.
  • Software Aging - Software rots. It generally ages badly, especially when maintenance people hack in quick fixes instead of cleanly excising the necrotic tissue and healing the wound.

  • Medical Upgrades - A systems engineering manager writes that the tsunami of embedded systems coming into his hospital have created new integration and support issues largely unaddressed by the vendors.

  • Keep It Clean - Successive maintenance cycles can make the code grow ever worse. The solution: refactoring.
  • Refactoring Mercilessly - To refactor or to not refactor, that is the question? Whether `tis nobler in mind to suffer the slings and arrows of outrageous bugs, or to refactor against a sea of troubles.
  • Discipline - Much of success in life stems from a disciplined approach to doing, well, everything. That applies to software engineering, too.
  • Code Inspection Book - Code inspections and reviews are a powerful bug-prevention tool. Here's a great book on the subject.
  • Quality Software - Quality starts first with a customer or team that demands great software. Then we use a reasonable process to deliver code that lives up to those demands.
  • Firware Maintenance - Those who study software have always claimed that maintenance is the biggest cost in software. But is this true for firmware?
  • Code Size - Some of us are working on huge programs. It appears, though, that most applications remain pretty small.
  • Expectations - When there's not an absolute expectation that products will be correct, they won't.
  • Know Your Numbers - Do you know your bug metrics? If not, why not?
  • Metrics - Few of us collect metrics. That's not what engineering is all about.
