Design debates drag on when each person argues from a different set of criteria. This deck states the decision needed, fixes the criteria first, gives each option the same treatment and ends on a recommendation with an owner and a date, so reviewers can agree, amend or reject.

The sample follows a fictional review at Foxhollow Digital on how order events reach billing at 2,500 requests per second: a database outbox, a managed queue and a self-run log. Replace the problem, the numbers, the options and the owners with those of your own review.
