Study Notes
System Analysis & Design
- System analysis and design is a presentation topic.
- The presenter is Menna Ibrahim Gabr.
Chapter 1 Agenda Part 2
- The agenda covers types of information systems.
- The agenda includes project team roles and skills.
Types of System
- Systems are categorized as physical/abstract and open/closed.
- A man-made information system is categorized as formal/informal or computerized.
- Subcategories are CBIS, DSS, MIS, ES, OS, TPS.
Types of Information Systems
- An information system is a collection of hardware, software, data, people, and procedures that generates data for daily, short-term, and long-term activities in an organization.
- Information systems are broadly classified into five categories: office information systems, transaction processing systems, management information systems, decision support systems, and expert systems.
Formal System
- A formal system has clear workflow communication, flowing downward, and authority.
- Information flows from the bottom to the top level of management.
- It's based on organizational charts.
- An example is a company's accounting system.
Informal & CBIS
- An informal information system is employee-based, dealing with personal and professional needs.
- It uses both formal and informal channels.
- A computerized information system, or CBIS, uses computers for handling business applications.
- An example is an office gossip network.
Classification of Information Systems
- Information systems are categorized by their operational and management support functions.
- Subtypes include Office Information System (OIS), Transaction Processing System (TPS), Management Information System (MIS), Decision Support System (DSS).
- Another subtype is Expert System (ES).
Office Information Systems (OIS)
- OIS utilizes hardware, software, and networks for enhanced workflow and employee communication.
- OIS, also known as office automation (OA), enables electronic tasks.
- As an example, a registration department might post class schedules online and email students.
Transaction Processing Systems (TPS)
- A TPS captures and processes data from a company's daily transactions.
- Transactions are business activities like deposits, payments, orders, and reservations.
- Examples of transactions include recording a student's registration, confirming an action, and maintaining data. A TPS can be batch or real-time.
Transaction Processing Systems (TPS)
- Batch processing collects transactions over a period and processes them later.
- Online transaction processing (OLTP) processes transactions immediately.
- Examples of OLTP include student registration, order handling, and receiving payments. This is common in modern systems.
Management Information Systems (MIS)
- An MIS is an informational system used to generate accurate, timely, and organized information to help managers make decisions.
- It's called a management reporting system (MRS) due to its regular reporting.
- MIS is integrated with TPS, processing sales orders, updating customer accounts, and producing sales reports.
Management Information Systems (MIS)
- MIS produces three main types of information: detailed, summary, and exception.
- Detailed information confirms transaction activities, like a detailed order report.
- Summary information consolidates information into an easily readable report, like an inventory summary report.
- Exception information highlights deviations from normal activity and requires immediate decision-making. An example might be an inventory exception report.
Decision Support Systems (DSS)
- A DSS supports decision-making using computerized programs.
- It compiles massive amounts of data.
- DSS helps in determining and planning courses of action.
Management Support Systems (MSS)
- Expert systems are AI software that simulates human expertise in a specific domain using knowledge bases.
- They preserve human expertise and help in tasks like medical diagnosis, accounting, coding, and games.
Management Support Systems
- Expert systems use stored knowledge to solve problems usually solved by human experts.
- Expert systems' structure usually involves input, user interface, rules engine, and knowledge base.
Management Support Systems
- Expert systems use knowledge bases to generate advice and explanations for the user.
- Data in knowledge bases is often added and curated by experts in the specified domain, to improve accuracy and provide reliable answers.
Organizational Levels
- TPS, OIS, and MIS typically support operational level functions.
- DSS and Expert systems are involved in tactical level and strategic level decision-making.
Project Team Roles & Skills
- Project team roles include Business Analyst, Systems Analyst, Infrastructure Analyst, Change Management Analyst, and Project Manager.
- Analysts need general skills (change management, ethics, communications, technical).
- Specific skills are needed by specific analysts.
