Squared Outline: Cases vs Stories

Use cases and users’ stories being the two major approaches to requirements, outlining their respective scope and purpose should put projects on a sound basis.

Cases & Stories

To that end requirements should be neatly classified with regard to scope (enterprise or system) and level (architectures or processes).

  • Users stories are set at enterprise level independently of the part played by supporting systems.
  • Use cases cut across users stories and consider only the part played by supporting systems.
  • Business stories put users stories (and therefore processes) into the broader perspective of business models.

Position on that simple grid should the be used to identify stakeholders and pick between an engineering model, agile or phased.
