Information System Analysis and Design Lecture 1 Introduction 2013923 ISA&D 1

Name: Nooruldeen Nasih Qader Qualification: Ph. D Computer Science, Data Mining, Bioinformatics, DB, 2013 MSc Computer Science, Sulaimani University, 2006 BSc Engineering Science, Baghdad University, 1993 Email: nnq 1@yahoo. co. uk 2013923 ISA&D 2

• Systems Analysis: understanding and specifying in detail what an information system (IS) should do • System Design: specifying in detail how the parts of an IS should be implemented 2013923 ISA&D 3

² Increasing size of organizations thus data volume increases ² Timely processing for fast action ² Better competitiveness with better information ² Increasing of complexity of organizations require innovative processing ² Same data can be processed in different ways ² Distributed organizations 2013923 ISA&D 4

• Success of IS’s depends on good ISAD • Widely used in industry - proven techniques • Large number of jobs today for computer science and engineering graduates is in creating IS for managing organizations • Should know types of information needed to manage organizations • Part of career growth in IT - lots of interesting and well-paying jobs! • Increasing demand for systems analysis skills 2013923 ISA&D 5

DATA : Raw Material ² Data collection costs money ² Collect only necessary and sufficient data ² Data is generally used by machines ² Data is useless unless it is processed to create information INFORMATION : Processed data ² Data processed by machines giving information ² Information is used to run an organization efficiently ² Information used by managers to initiate actions 2013923 ISA&D 7

what is the differences between information and knowledge 2013923 ISA&D 8

² Should know nature of organizations and their structure to design appropriate IS. ² Should know management structure and needs of each level of management ² Should know functional areas of management and information needs for each area 2013923 ISA&D 9

² STRATEGIC : Needed for long range planning and directions. ² Eg: machine replacement, augmentation, and modernization. ² TACTICAL : Needed to take short range decisions to improve profitability and performance. ² Eg: Identifying and controlling areas of high cost, critical bottlenecks in production. ² OPERATIONAL : Needed for day to day operations of the organization. ² Eg: Daily Sales, Billing. 2013923 ISA&D 11

Quality How to ensure quality ² Trustworthy Do not hide unpleasant information. ² Relevant Understand user needs. ² Brief Summarize relevant information. ² Up-to-date Include all data up to present time. ² Significance Use attractive format & graphical charts. 2013923 ISA&D 13

² Provide new ways of looking at information in the world in order to solve business problems ² Introduce concepts and methods of ISAD ² Describe the systems development life cycle (SDLC) ² Learn effective methods for gathering essential information during system analysis ² Learn approaches to documenting and modeling of gathered information ² To teach you effective methods for designing systems to solve problems effectively using technology 2013923 ISA&D 14

² System’s concept ² The system development environment ² Types of information systems ² Rapid application development ² Role of the systems analyst ² Managing an IT project ² Initiating and planning a systems development project 2013923 ISA&D 15

² Determining systems requirements ² Process modeling ² Logic modeling ² Project documentation ² Understanding the elements of systems design ² Designing the user interface ² Designing system interfaces, controls and security 2013923 ISA&D 16
