Key summary

Despite advancements in tooling, 'it works on my machine' still happens in 2026 due to environment drift, leading to significant engineering waste and time spent managing multiple environments.

TL;DR

  • Environment drift is a leading cause of engineering waste.
  • Code runs inside an environment, which is rarely identical across machines.
  • Developers spend 40% of their time on tasks unrelated to writing features.
  • Environment debugging is a major culprit.
  • Managed platforms can help reduce environment drift and engineering waste.
  • Consistency is an ownership question, not a tooling question.
  • Local success doesn't reflect production conditions.
  • Teams are choosing managed platforms to reduce environment drift and improve consistency.
