Instead, it concentrates on how the output of task analysis can be used as input to design and though out the design process. The core of OVID is class diagrams showing the designer's model. However, exercises will be conducted using pencil and paper. Objects Stage 1 of the process is to find the objects that the user will deal with. Although several users' models may be found the objective is to consolidate to a single designer's model that is appropriate to all the users.
Analysis starts with the most frequent tasks.
These are used to find the most concrete objects and the strongest relationships between them. As analysis proceeds the model is expanded to map the relationships for all tasks. In later iterations of the object model the design will express the most significant attributes as objects. It often emerges that some users think of two classes as distinct when the designer thinks these are variants of the same object. The next section deals with how to find the views of the objects that are needed .
