5 questions in Business Capabilities.

  1. Business Capabilities advanced

    A retailer validates and stores a customer delivery address in three places: checkout, the logistics planner, and support tooling. Each implementation is defensible on its own terms and each team resists change. About 3% of orders fail first-time delivery for address-quality reasons. Walk me through how you would approach this.

  2. Business Capabilities beginner Multiple choice

    A retailer's "price a basket" capability is called by two things. The search grid calls it 40000 times a second and needs an answer in about 20 ms where a penny of error is acceptable because the basket is re-priced at checkout. Invoicing calls it 50 times a second and needs an exact figure that can be reproduced in an audit seven years later. A single shared pricing service is proposed on the grounds that there is one capability. What settles whether that is one service or two?
