IEEE Transactions on Software Engineering, Vol. 24, No. 12, Dec. 1998. Authoring is part of a two step process of scenario authoring goal discovery . On the one side, scenarios are used to discover new goals, and on the other side, goals are the input for scenario authoring. To any scenario is attached a goal.
Goals express in part the requirements for the designed system.
They are written as a verb together with one or several parameters, and they are illustrated by scenarios. Guiding Goal Modelling Using Scenarios . Submitted to the TSE Journal, special issue on scenarios, 1998. From this combination, he deduces the relationship of variation between scenarios. Other relationships could also be considered.
