  1. System Development 1 Lecture 3

  2. In this lecture…and in the next • Describe the system development process • List the steps • Discuss activities performed at each step • Describe who is involved in the process • Discuss the importance of project management and documentation • Describe the role and qualities of a system analyst • Recognise that programming is a part of the system development cycle

  3. A system • A collection of elements and activities organised to achieve a goal • The solar system • Air conditioning • Home theatre • A computerinformationsystem

  4. Computerised information system • Elements • People, procedures, hardware, software, data, connectivity • Goal • To provide complete, accurate, relevant and timely information

  5. Systems Development Cycle • Software development is a complex process. • A system (software) may have a number of errors if not developed with proper planning • To minimize errors and improve quality, an organised approach is followed that is called System Development Cycle. • System Development cycle is consists of phases, and in the each phase a particular task is performed • There are many SDC models with slight differences

  6. The five phases of the SDC: • Planning • Analysis • Design • Implementation • Operation, support and security

  7. What starts the SDC? • SDC is used for new information systems and for modifying existing systems • Different reasons • Organisation development and growth • Correct errors • New hardware/software e.g. incorporate wireless • Security threats • Remain competitive

  8. What is systems analysis? • A field of knowledge concerned with developing information systems • Develops strategies for improved planning, organization, control and execution of information system projects • Implements the systems development cycle • An organized procedure for planning and building information systems

  9. A system analyst • A computer and problem solving professional • Works with the organisation to steer the system development cycle • Works with all stakeholders • Has IT and business expertise • Is often a contractor

  10. Skills required by systems analysts • Working knowledge of information technology • Computer programming experience and expertise • General business knowledge • Problem-solving skills • Interpersonal communication skills • Interpersonal relations skills • Flexibility and adaptability • Character and ethics • Systems analysis and design skills

  11. Communication is important • The system analyst works with: • All levels of management • System users • Customers and suppliers • Government agencies • Hardware and software suppliers

  12. Where Systems Analysts Work • In traditional businesses • project teams • In outsourcing businesses • contracted to businesses • In consulting businesses • contracted to businesses • In application software businesses • building software products for businesses
