Click here for my just published interview on Technical Debt. Major themes discussed in the interview are as follows:

  • The nature of technical debt
  • Tactical and strategic effects of technical debt
  • How the technical debt metric enables you to communicate across levels and functions
  • What Toxic Code is and how it is related to Net Present Value
  • The atrocious nature of code with a high Error Feedback Ratio
  • Cyclomatic complexity as a predictor of error-proneness
  • Use of heat maps in reducing technical debt
  • Use of density of technical debt as a risk indicator
  • How and when to use technical debt to ‘stop-the-line’
  • Use of technical debt in governing software

To illuminate various subtle aspects of technical debt, I use the following metaphors in the interview:

  • The rusty automobiles metaphor
  • The universal source of truth metaphor
  • The Russian dolls metaphor
  • The mine field metaphor
  • The weight reduction metaphor
  • The teeth flossing metaphor

Between the themes and the metaphors, the interview combines theory with pragmatic advice for both the technical and the non-technical listener.
