Study Notes
Information Systems
- Information is a key resource that fuels businesses and can determine their success or failure.
- Managing computer-generated information differs from handling manually produced data.
Systems Analyst Roles
- Systems analysts recommend, design, and maintain various types of systems for users.
- The systems analyst may be involved at each organizational level (strategic, knowledge, operational).
- Systems analysts can be consultants (outside perspective), supporting experts (internal expertise), or agents of change (facilitating change).
System Types
- Transaction Processing Systems (TPS): Manage day-to-day operations, such as order processing and payroll.
- Office Automation Systems (OAS): Improve office productivity with tools like word processors and email.
- Knowledge Work Systems (KWS): Support professionals in tasks requiring expertise, like modeling and simulation.
- Management Information Systems (MIS): Provide information summaries for managerial decision-making.
- Decision Support Systems (DSS): Aid in complex decision-making by analyzing data and generating insights.
- Expert Systems (ES): Provide expert advice for specific domains by mimicking human reasoning.
- Executive Support Systems (ESS): Offer high-level summaries and trends for executives.
- Group Decision Support Systems (GDSS): Facilitate collaboration in group decision-making environments.
- Computer-Supported Collaborative Work Systems (CSCWS): Enable teams to work together remotely.
Systems Development Life Cycle (SDLC)
- The SDLC is a phased approach to solving business problems using a specific cycle of analyst and user activities.
- It is broken into seven phases:
- Identifying Problems, Opportunities, and Objectives
- Determining Human Information Requirements
- Analyzing System Needs
- Designing the Recommended System
- Developing and Documenting Software
- Testing and Maintaining the System
- Implementing and Evaluating the System
System Enhancements
- Systems can be enhanced to add new features, respond to business changes, or accommodate changes in hardware and software.
Case Tools for Systems Analysts
- CASE tools are productivity tools for systems analysts to improve routine work through automated support.
- They can improve analyst productivity, improve communication between analysts and users, integrate life cycle activities, and help assess maintenance changes.
Case Tool Classifications
- Upper CASE tools perform analysis and design tasks. They help with modeling, defining system boundaries, and prototyping screens and reports.
- Lower CASE tools generate programs from CASE designs, often in multiple programming languages.
- Integrated CASE tools perform both upper and lower CASE functions.
Object-Oriented Systems Analysis and Design
- This approach to systems development focuses on objects and their interactions, facilitating rapid changes in dynamic environments.
- It relies on iterative development: analyzing, designing, and implementing a small part of the system at a time.
Open Source Software
- Open source software is free to distribute, share, and modify, contrasting with proprietary code that is hidden from users.
- It is characterized as a philosophy that promotes collaboration and open access.
- Examples include Linux, Apache Web Server, and Mozilla Firefox.
Benefits of System Analysis and Design
- Proper planning and design are crucial for creating systems that meet user needs and avoid falling into disuse.
- Systematic processes improve business processes through the use of computerized information systems.
Analyst Qualities
- Problem solver: Approaches analysis as a challenge and enjoys developing solutions.
- Communicator: Needs enough computer experience to understand programming, system capabilities, and user needs.
- Ethically sound: Possesses strong personal and professional ethics.
- Self-motivated: Is self-disciplined, self-motivated, and can coordinate resources and personnel.
Human-Computer Interaction (HCI)
- HCI principles are increasingly important to improve system quality and user experience.
- They consider user needs, including physical ergonomics, usability, aesthetics, and behavioral aspects.
Maintenance
- System maintenance can remove software errors and enhance existing software.
- Over time, the cost of maintenance can exceed the cost of developing a new system.
Conclusion
- The SDLC provides a structured framework for developing systems, considering users' needs, and ensuring effective implementation and ongoing maintenance.
- CASE tools and object-oriented design methodologies expand the tools available to systems analysts.
- The role of the systems analyst continues to evolve in a dynamic environment, requiring them to adapt and innovate in their work with information systems.
