Study Notes
- Information fuels business and determines its success or failure.
- Information must be managed correctly, especially when computer-generated.
Systems Analyst's Role
- Systems analysts recommend, design, and maintain systems for users, and may be involved with systems at any organizational level.
- Systems analysts must be able to work with all kinds of people and be experienced with computers.
- Primary roles: consultant, supporting expert, and agent of change.
- Qualities include being a problem solver, communicator, ethical, self-disciplined, and self-motivated.
Types of Computer-Based Systems
- Transaction Processing Systems (TPS) process large amounts of data for routine business transactions, supporting the day-to-day operations. Examples are payroll and inventory management.
- Office Automation Systems (OAS) support data workers who share information but do not usually create new knowledge. Examples include word processing and email.
- Knowledge Work Systems (KWS) support professional workers like scientists and engineers. Examples include computer-aided design systems.
- Management Information Systems (MIS) support a broad spectrum of tasks, including decision analysis.
- Decision Support Systems (DSS) aid decision-makers.
- Expert Systems (ES) capture and use expert knowledge to provide recommendations.
- Executive Support Systems (ESS) help executives make unstructured strategic decisions.
- Group Decision Support Systems (GDSS) allow group members to interact with electronic support.
- Computer-Supported Collaborative Work Systems (CSCWS) is a term that is more general than GDSS, and may include "groupware".
Integrating New Technologies
- Systems analysts need to be aware of how integrating new technologies affect all types of systems.
- New technologies to be integrated, include ecommerce and web systems, Enterprise Resource Planning (ERP) systems, wireless systems, and open-source software.
- Benefits of Ecommerce and Web Systems: Increasing user awareness, 24-hour access for users, improved interface design, and global reach.
- Enterprise Resource Planning (ERP) Systems: Integrate information systems across different management levels and functions. Examples include SAP and Oracle.
- Wireless Systems: Systems analysts design wireless communication networks for integrating voice, and video. Wireless communication is referred to as m-commerce.
- Open Source Software: Offers an alternative of traditional software development where proprietary code is hidden from the users
- There is a continued need for systems analysis and design, because installing a system incorrectly can lead to user dissatisfaction and disuse.
Systems Development Life Cycle (SDLC)
- The systems development life cycle (SDLC) is a phased approach to solving business problems. It is developed through analyst and user activities.
- Each phase has unique user activities.
SDLC Phases
- Identifying Problems, Opportunities, and Objectives: Interviewing, summarizing knowledge, scope estimation, and documenting results in a feasibility report is required.
- Determining Human Information Requirements: Interviewing, hard data sampling, questionnaires, observation, and prototyping are used to understand what users need to make the new system usable.
- Analyzing System Needs: Create data flow diagrams, complete the data dictionary, analyze structured decisions and prepare and present the system proposal. Output a recommendation about how the system should be built
- Designing the Recommended System: Design procedures for data entry, design the human-computer interface, design system controls, design files and/or database and design backup procedures.
- Developing and Documenting Software: System analysts work with programmers to develop software and produce documentation.
- Testing and Maintaining the System: Testing, system maintenance, and documenting maintenance and problems helps create updated programs.
- Implementing and Evaluating the System: Training users and system evaluation leads to trained and experienced personnel.
