ed Structured Systems Analysis & Design UNISA studies – Chap 1 Objectives of Chapter 1
* Explain the key role of a system analyst in business.
* Describe the various types of system and technology an analyst might use. * Explain the importance of technical skills, people skills and business skills for an analyst. * Explain why ethical behaviour is crucial for a system analyst’s career. * Describe various job titles in the field and places of employment where analysis and design work is done. * Discuss the analyst's role in strategic planning for an organization. * Describe the analyst’s role in systems development projects.
