The Architecture Decision Playbook

Architecture decisions outlive the people who make them by years. This playbook is how we evaluate stack choices for our own builds, without falling into the trap of picking the trendy thing or the safe thing instead of the right thing. Coming soon: early May 2026.

The Architecture Decision Playbook

What you'll get

  • A scoring rubric for build-vs-buy that goes beyond "do we have the engineers"
  • When monolith beats microservices (more often than the internet thinks)
  • How to evaluate a database for the next 5 years, not the next 5 weeks
  • A list of the technology choices that have aged well, and the ones that have not
01

In production

This playbook is being written now and ships in early May 2026. In the meantime, the Software Procurement Playbook covers a lot of the same evaluation discipline applied to buying tools, and most of it transfers directly to architecture decisions.

Want a heads-up when this drops? Drop us a line and we will email you the day it goes live.

30-minute call with our team. Walk us through what you're weighing and we'll give you honest input — no pitch unless you ask for one.
