In the first post of this series, we argued that architecture should come before tools: Platform decisions do not fail because the wrong tool gets picked, but because architecture enters the conversation too late. Fair enough. But at some point, you have to pick a tool. The question is how. And for most organizations, my honest answer is: often badly. A CTO reads a Gartner report. A project lead attends a vendor event. Someone in procurement remembers a name from a previous job. Three demos get scheduled. Features get compared in a spreadsheet. The tool with the best demo wins. This post describes a different approach. One that starts with your own strategic context, reduces the market systematically before you ever talk to a vendor, and ends with a shortlist that represents genuinely different architectural options rather than three flavours of the same thing.

This post is the starting point of a series about how to make better platform decisions. Not by buying better tools, but by designing better architecture.
