EXTRACTING AND STATING USER INTERFACE PROTOTYPE REQUIREMENTS

Rares Sfirlogea

Method Engineering

Some definitions• Requirements engineering – phase in the development

process of a project in which it is identified what is the goal of the application and how is it going to be implemented

• User Interface and Requirements Prototype – a requirement document that provides a sketch of the system’s functionality, design and structure in a way that is easily understood by all parties involved in the development process

Method reason• Complex projects => a lot of requirements documents

• Application user manual• Requirements rationale• Software requirements specification• User interface and requirements prototype• …

• Requirements engineers usually continue working on other projects once the documents are complete

• The implementation team has a hard time answering questions when the the requirements documents disagree

Method description• Addition to the steps made in User Interface and

Requirements Prototyping and other requirements modeling methods

• Ensures that the developers can answer the question of what the UIRP specifies and what it does not

• Consists of six “recurrent” steps:• Define the system operational environment and its interfaces to other

systems• Identify to which application domains the system belongs• Characterize the principal properties and the main features of the

application belonging to these domains• Identify which of these features are applicable to the system under

development• Decide and document which of these features are going to be prototyped• Prototype the chosen features
