  1. Business Understanding advanced

    A food-delivery marketplace takes a 12% commission on an average order of 400 rupees, and its contribution after paying delivery partners and payment fees is about 15 rupees per order. The platform team proposes a design that costs 3 rupees per order in infrastructure. Is that acceptable, and what does the answer change about the architecture?

  10. Constraint Thinking beginner Multiple choice

    A team must ship a compliance-driven reporting system by a fixed statutory date nine months away. There are three engineers, no operations staff, an existing Postgres database, and no budget for new licences. Which constraint should drive the architecture?

  11. Constraint Thinking intermediate

    Treat an operator's attention late in an incident as a hard constraint rather than a behaviour to coach. In January 2017 a GitLab engineer working past the end of their shift ran a destructive command against the primary database host instead of the replica. Which controls change that outcome and which are theatre?
