The first activity of an embedded development project should be

  • A.establishing what the product must do and under what constraints
  • B.selecting the microcontroller to be used
  • C.ordering the development boards for the team
  • D.writing the start-up code for whichever part has been chosen

Answer: A

Every later decision, the part included, follows from the requirement, and a part chosen first constrains the requirement rather than serving it. Requirements written down are also what a test can later be traced back to.
