Integration Vendor Questionnaire

By Graham O'Shea, Founder and Lead Developer  ·  1 August 2026  ·  Part of The Agentic AI Guide

An integration product is a programming language with a toolchain attached. These ten questions find out which language your business rules end up written in, and who controls it.

What Is In The Integration Vendor Questionnaire

  • What language your integration logic actually ends up in.
  • Whether that language is usable outside the product.
  • Whether you can put the source in your own version control.
  • Whether you can read a diff between two versions of a rule.
  • How many people can work on it, and whether they can work at once.
  • What a mandate to use one tool for everything costs you.
  • How to read the answers, and what they tell you about year two.

Why It Starts With The Language

Byars's point is that integration products are not products that directly solve a business problem. They are programming languages, bundled with a toolchain and a runtime. Once you accept that, the buying decision stops being a feature comparison and becomes a question about who can read your business rules in five years.

The full reasoning is in the article this accompanies: Systems Integration Is A Language Choice, Not A Purchase.

Prefer A Second Opinion On Your Integration Shortlist?

The scoping audit is free. The form asks for your website or store URL and a note on what is eating the time, and an integration you are weighing up is a reasonable thing to put in that box.
