JAD workshop participants examine each process in turn to select the most appropriate technique or techniques to implement it, taking into account: time constraints for the process, volumes, type of user, design objectives of system, and technical context (e.g., hardware/software available).
¤ One-to-One Mapping
Firstly, an attempt is made to map each process to a single procedure. One-to-one mapping is most desirable because:
* Each elementary process is a complete activity from the user's point of view, and hence the procedure will be meaningful to the user, and will leave the database in a consistent state
* A change in an elementary process (due to a business change) will only require a change to the single procedure
¤ Alternative or Serial Procedures
Consideration is given to the use of alternative or serial procedures to implement the process. The details of the procedure, including its name, definition, techniques, constraints, and the elementary processes it supports are recorded in the Information repository.
* Alternative Procedures
More than one procedure may be required if the same process is performed in different processing environments, by users with different skill levels, or on different hardware or software platforms.
* Serial Procedures
Several processes may best be performed by one procedure, termed a compound procedure. This may be an appropriate mapping when multiple processes are always performed in series, several similar processes involve the same entity type, or procedures are generalized.
