requirements engineering use case training cockburn debate

  • Is a use case a requirement or just a story? Is a scenario just another name for a use case? Is a use case a formal, semi-formal, or informal structure? Is there a linking structure for use cases, or do they just come in piles?
  • make use cases “rigorous
  • People want a fairly informal medium in which to express their early thoughts
  • ...28 more annotations...
  • handling all the variations a system must handle.
  • Using these semi-formal structures, we can both Assert that use cases really are requirements and need a basic structure, and also Allow people to write whatever they want when they need to.
  • Here is the semi-formal structure
  • Linking use cases to actors’ goals
  • If the software supports those goals, the software will yield the greatest business value.
  • goals sometimes fail
  • failure handling
  • Therefore, a use case is structured into two sections: the sequence of actions when everything goes well, followed by various small sequences describing what happens when the various goals and subgoals fail.
  • Why do we write things in the use case that are not externally visible behaviors?
  • contract between stakeholders
  • there remained a split between those who still wanted to keep use cases short and informal and those who wanted them to be detailed
  • Here are four key pieces of advice that you should note from the evolution of use cases.
  • readable use cases might actually get read
  • Prepare for Multiple Formats
  • Only Use Them When the Form is Appropriate
  • Be Aware of Use Case Limits
  • Use cases should not be used to describe UI designs
  • use case is normally intended as a requirements document, and the UI design is a design
  • The same system feature is likely to show up as a line item in multiple use cases
  • Use cases have a basic mismatch with feature lists
  • Use cases are not test plans or test cases
  • Avoid the Standard Mistakes in Use Cases
  • The two most common and most costly to the project are including too many details and including UI specifics
  • it’s just that by the time I get subgoals at a good level and remove the design specifics, the task is less than nine step
  • The greatest value of the use case does not lie in the main scenario, but in alternative behaviors
  • If the main scenario is between three and nine steps long, the total use case might only be two or three pages long, which is long enough.
  • The Stakeholders and Interests model fills the holes in the Actors and Goals model
  • Originally published in STQE magazine, Mar/Apr 2002

  • INCOSE Requirements Management Tools Survey
  • The survey responses, including the rating of compliance with each question or feature, are provided by the tool vendors directly. However, the TDWG reserves the right to review and correct any "informational injustices" (i.e. exaggerated answers).
