WHICH ONE IS NOT ONE OF THE THREE? o Sales and support of ERP software o Auditing, compliance and security o Web development o Hardware electronic assembly  DURING WHICH PROCESS DO EXECUTIVES TRY TO ANSWER KEY QUESTIONS ABOUT THE COMPANY? o Business process reengineering o Strategic planning o Information systems strategic planning o Enterprise resource planning (ERP)  A DESCRIPTION OF THE HARDWARE, SOFTWARE AND COMMUNICATION NETWORKS REQUIRED TO IMPLEMENT PLANNED INFORMATION SYSTEMS IS CALLED o Information systems plan o Applications architecture planning o A technology architecture plan o Enterprise technology planning  WHAT IS THE LAST STEP OF THE ANALYST’S APPROACH TO PROBLEM SOLVING? o Monitor to make sure that you obtain the desired results o Decide which solution is best, and make a recommendation o Verify that the benefits of solving the problem outweighs the costs o Implement the solution  THE TWO SYSTEMS THAT ARE EXTERNALLY ORIENTED, I E THEY FOCUS ON ENTITIES OUTSIDE OF THE ORGANISATION ARE ___________ o Collaboration support and knowledge management systems o Manufacturing and supply chain management systems o Accounting/financial and human resource management systems  WHICH ONE OF THE FOLLOWING ACTIVITIES IMPROVES THE PERFORMANCE OF THE COMPANY? SELECT THE MOST APPROPRIATE OPTION: o Business process reengineering o Strategic planning o Technology impact planning o Enterprise resource planning  THE PRIMARY OBJECTIVE OF THE ANALYSIS PHASE IS TO_____________ o Analyse the capabilities and structure of the previous system o Prioritise the alternatives for a system o Determine the basic structure and approach for the new system o Understand and document the user’s needs and requirements  WHAT IS THE FIRST OFFICIAL ACTIVITY OF THE PROJECT TEAM AS IT INITIATES THE PROJECT PLANNING PHASE? o Define the business problem o Staff the project team o Develop a cost/benefit analysis o White a project proposal  WHICH ONE OF THE FOLLOWING DESCRIBES A PLANNED UNDERTAKING THAT PRODUCE A NEW INFORMATION SYSTEM? o Systems development project o Phase o Systems development life cycle (SDLC) o Design phase  WHICH OF THE FOLLOWING DESCRIBES AN APPROACH OF PROGRAMMING WHICH BREAKS MORE COMPLEX PROGRAMS INTO A SUBSET OF PROGRAM MODULES? o Incremental o Iterative o Generalization-subgeneralisation o Top-down  ONE MAIN PRINCIPLE OF STRUCTURED DESIGN IS THAT PROGRAM MODULES SHOULD BE DESIGNED SO THAT THEY ARE __________. o Highly engineered o Tightly coupled o Highly cohesive o Rapidly prototyped  A KEY CONCEPT IN THE ______ MODEL APPROACH IS THE FOCUS OF RISK. o Risk o Extreme programming (XP) o Spiral o Agile  WHICH OF THE FOLLOWING IS NORMALLY THE MOST TIME-CONSUMING AND RESOURCEEXPENSIVE OPERATION? o Building prototypes o Observing business processes o Reviewing existing reports o Interviewing stakeholders  QUESTIONNAIRES CAN BE USED TO ASK QUESTIONS THAT _________. o Determine user opinions o Determine the stakeholders o Define the systems functions o Detail user procedures  WHICH ONE OF THE FOLLOWING OPTIONS DESCRIBES THE CHARACTERISTICS OF A PROTOTYPE? o Includes work procedures, both extensive and throwaway o Is operative and executable, is focused on a specific objective, is quickly built o Has a good look and feel, is executable, and is complete o Is quickly built, has a mock-up, and is complete  WHAT IS THE MAIN PURPOSE OF JOINT APPLICATION DESIGN (JAD)? o To establish a design environment o To design a prototype o To expedite the design of the system o To expedite the investigation of system requirements  WHICH SYSTEM MODEL SHOWS WHAT THE SYSTEM IS SUPPOSED TO DO IN GREAT DETAIL, WITHOUT COMMITTING TO ANY ONE TECHNOLOGY? o Vertical o Physical o Logical o Hardware  THE MODERN STRUCTURED ANALYSIS TECHNIQUE USES DATA FLOW DIAGRAMS (DFDs) AND __________. o Entity-relationship diagrams (ERDs) o Activity diagrams o Decision support systems (DSS) o Workflows
