requirements mbse: questions
How is this ranking made?
By the number of companies whose own job postings name the tool as the team's system, from the Breaknorm technology catalogue (version T-1.0.1-prov). No vendor paid for a position and no editor chose the order.
Why is this different from review-site rankings?
Review sites rank by reviews collected. This ranks by companies hiring people to work in the tool, which is closer to seats in use. It under-counts tools used by teams that rarely post jobs.
What about product editions?
Editions and sub-products () are counted under the parent so no company is counted twice.
Can I get the companies behind a number?
Yes: click a tool, see the first 20, and sign up for the full list with verified e-mails. Counting is free.
