Lezione 4. Requirements


What is a requirement?

  • It may range from a high-level abstract statement of a service or of a system constraint to a detailed mathematical functional specification…

  • …since requirements may serve a dual function

    • May be the basis for a bid for a contract - therefore must be open to interpretation (client ==> potential developers)
    • May be the basis for the contract itself - therefore must be defined in detail (developer ==> potential client)
