  1. SSADM vs UML We examine the two Methods { SSADM And UML} • In terms of their manner of handling System Elements. In each case comparisons transgress the Object vs. Non-Object oriented paradigms nevertheless the scope of the activities is similar. Renaat Verbruggen

  2. Data/Events/Processes • 1.      Data • Logical Data Model (LDM) • The class diagram • 2.      Events • Entity Life History (ELH) • The Behaviour (interaction) diagrams • 3.      Processes • Data Flow Diagram (DFD) • The activity diagram Renaat Verbruggen

  3. Interfaces /Resources • 4.      Interfaces • Dialogue Design • Modelled in class and component diagrams. • 5.      Resources • Requirements Catalogue (RC). • Modelled by using the stereotype feature. Renaat Verbruggen

  4. Quality / Business issues • 6.      Quality • Requirements Catalogue (RC). • A. In analysis explorative prototypes. • B. In design experimental prototypes • 7.      Business issues • A. Data Flow Diagrams (DFD). • B. Entity Life History (ELH). • Activity diagrams describe and model business process. Renaat Verbruggen

  5. Identify the problem/User involvement • 8.      Identify the problem or problem objectives • The strategic planning defines the problem that needs to be solved. • The strategic planning defines the problem that needs to be solved. • 9.      User involvement • A. Gathering information about system. • B. Reviewing products of each stage. • A. Gathering information about system in use case models, CRC and tech. dictionary. • B. Review/check prototypes. Renaat Verbruggen

  6. Organisational structure/ Employee job satisfaction • 10.   Organisational structure, goals and policies • Strategic planning looks at organisational structure giving Project Initial Document. • Activity diagram models organisational structure and integration. • 11.   Employee job satisfaction • User may choose Business System Option (BSO) that defining impact on users and training. • Allowing employees to choose suitable way to perform assigned job. Renaat Verbruggen

  7. Different point of views / Employee values • 12.   Different point of views • Different views of the system are documented in Requirements Catalogue. • Analyst considers different views of system and resolves contradictions. • 13.   Employee values • Not Supported. • Not Supported. Renaat Verbruggen

  8. System acceptability and usability • 14.   System acceptability and usability • A. User involvement in developing system. • B. Use prototype. • C. Study of system impact on staff. • Involvement of users in experimental prototypes to verify usability/acceptability of system. Renaat Verbruggen

  9. LDM BAM DFM ELH Renaat Verbruggen
