(Alternatively: Why Waterfall Still Beats Agile)

Thesis

  • Upfront design and planning and batching reduce maintenance (and maintenance is costly). Agile pushes design/planning to the implementation phases. This is bad.

Arguments

  • Anecdote: doctors vs. car mechanics — building things while the engine is running.

    • Agile is specifically designed for building systems while the engine running.
  • Would agile work for building homes? Building spaceships? If not, why should we expect it to build durable software?

Potential Solutions

  • Make the product backlog immutable — any additional features have to occur in subsequent versions of the product.

    • Product versions are treated as completely different codebases.
