A use case diagram [1] is a graphical depiction of a user's possible interactions with a system. A use case diagram shows various use cases and different types of users the system has and will often be accompanied by other types of diagrams as well. The use cases are represented by either circles or ellipses. The actors are often shown as stick ...
Goal structuring notation (GSN) is a graphical diagram notation used to show the elements of an argument and the relationships between those elements in a clearer format than plain text. [1] Often used in safety engineering , GSN was developed at the University of York during the 1990s to present safety cases . [ 2 ]
In software and systems engineering, a use case is a potential scenario in which a system receives an external request (such as user input) and responds to it. A use case is a list of actions or event steps typically defining the interactions between a role (known in the Unified Modeling Language (UML) as an actor) and a system to achieve a goal.
Intentional elements are: goal, soft goal, task, belief and resource. Goal is condition or situation that can be achieved or not. Goal is used to define the functional requirements of the system. In GRL notation goal is represented by a rounded rectangle with the goal name inside. Task is used to represent different ways of how to accomplish goal.
A context diagram can also list the classifications of the external entities as one of a set of simple categories [5] (Examples: [6]), which add clarity to the level of involvement of the entity with regards to the system. These categories include: Active: Dynamic to achieve some goal or purpose (Examples: "Article readers" or "customers").
Strategic planning is an organization's process of defining its strategy or direction, and making decisions on allocating its resources to attain strategic goals.. Furthermore, it may also extend to control mechanisms for guiding the implementation of the strategy.
UML's use case diagram provides a simple goal modeling notation. The bubbles name functional goals, [14] so a Use case diagram forms a simple functions-only goal model: as Cockburn writes, use cases cover only the behavioral requirements. [15] Roles are shown as actors (stickmen on the diagram), linked to the use cases in which they take part.
Bloom's taxonomy is a framework for categorizing educational goals, developed by a committee of educators chaired by Benjamin Bloom in 1956. It was first introduced in the publication Taxonomy of Educational Objectives: The Classification of Educational Goals. The taxonomy divides learning objectives into three broad domains: cognitive ...
