DSDM Practice - Modelling Flashcards
What are the 4 purposes of modelling in DSDM
To improve understanding through visual representations
To support transparency by simplifying core elements of a requirement, usually in a picture
To abstract the most relevant information for clarity (see below)
To allow cross-checking for consistency
What are some modelling examples?
A storyboard to represent a television advertisement
Architectural blue-prints to define a housing development
An artist’s impression of a landscaped park
Flowchart
A scale model of a car to be built
Process diagrams to establish the required functionality to be supported by a software solution
A network diagram showing components of a communications network
What DSDM principle does modelling meet?
DSDM has the principle communicate continuously and clearly, and advocates using visual communication
What can modelling help the team be clear about?
During the Foundations phase of the project, when a high-level Prioritised Requirements List is being compiled, models can help the whole team be clear about the scope and the boundaries of the solution. One modelling example for foundations is the use of user story mapping.
What perspectives should be considered when Modelling?
Modelling perspectives
A coherent picture of a solution area can be gained by considering the perspectives: “what”, “where”, “when”, “how”, “who” and “why”, and the relationships between them.
