Assumption Based Development vs Behavior Driven Development

Developers should use Assumption Based Development when working on projects with high uncertainty, such as new product development, innovative features, or complex systems where requirements are unclear meets developers should use bdd when building complex applications where clear communication between technical and business teams is critical, such as in agile projects with evolving requirements or regulatory environments needing precise documentation. Here's our take.

Assumption Based Development

Developers should use Assumption Based Development when working on projects with high uncertainty, such as new product development, innovative features, or complex systems where requirements are unclear

Assumption Based Development

Nice Pick

Developers should use Assumption Based Development when working on projects with high uncertainty, such as new product development, innovative features, or complex systems where requirements are unclear

Pros

  • +It's particularly valuable in agile and lean environments to prevent wasted effort on invalid assumptions, enabling faster pivots and more reliable delivery
  • +Related to: agile-methodology, lean-software-development

Cons

  • -Specific tradeoffs depend on your use case

Behavior Driven Development

Developers should use BDD when building complex applications where clear communication between technical and business teams is critical, such as in agile projects with evolving requirements or regulatory environments needing precise documentation

Pros

  • +It helps prevent misunderstandings by creating living documentation that describes system behavior in plain language, reduces rework from misinterpreted specs, and ensures features meet actual business needs through automated acceptance tests
  • +Related to: test-driven-development, agile-methodologies

Cons

  • -Specific tradeoffs depend on your use case

The Verdict

Use Assumption Based Development if: You want it's particularly valuable in agile and lean environments to prevent wasted effort on invalid assumptions, enabling faster pivots and more reliable delivery and can live with specific tradeoffs depend on your use case.

Use Behavior Driven Development if: You prioritize it helps prevent misunderstandings by creating living documentation that describes system behavior in plain language, reduces rework from misinterpreted specs, and ensures features meet actual business needs through automated acceptance tests over what Assumption Based Development offers.

🧊
The Bottom Line
Assumption Based Development wins

Developers should use Assumption Based Development when working on projects with high uncertainty, such as new product development, innovative features, or complex systems where requirements are unclear
