Foundation for System Development Group 1  INTRODUCTION Embarking on a journey as a systems analyst opens the door to a dynamic and evolving career, where you can continually apply and refine your diverse skills. Rather than just a role, it is a path that fosters innovation, problem-solving, and continuous learning. This foundational phase aims to inspire and broaden your understanding of the exciting opportunities within systems analysis and design.  The System Development Environment Unit 1  OVERVIEW This chapter introduces students to systems analysis and design and the components of the systemsdevelopment environment. Students are introduced to several systems development components, including the process and data- oriented approaches to systems development; different types of information systems; and the systems development life cycle.  OBJECTIVES to system s an alys is an d d esign, with efine and discuss the modern approach D at a vi ews of systems. of both pro cess an d d an emphasis on the combination le (SD LC ) an d e x plain how stem s de ve lop m e nt life cyc e fiv e s te ps in thes y P a rt II an d running.
