The problem
Competitive analysis always starts at a whiteboard. You draw a 2x2 with the axes that matter for your market, price vs. capability, enterprise vs. SMB, breadth vs. depth. You place competitors as dots. You argue about where your own dot belongs. The spatial layout of the map reveals things a spreadsheet doesn't: who's crowded, where the white space is, who's positioned directly against you vs. who's in an adjacent space.
Then you try to turn the whiteboard into a deliverable. A slide deck, a one-pager for the board, a wiki page for the team. The 2x2 becomes a bullet list. The spatial relationships become 'Company A is better at X but weaker at Y.' The insight gets stripped out in the translation.
Competitive analysis documents are also quickly stale. A competitor ships a new feature, a new player enters the market, and your 90-day-old doc is wrong. The team needs to update the map, not rewrite the doc from scratch.
