Introduction to Systems Analysis & Design Chapter #1

Systems analysis and design Is a step-by-step process for developing high- quality information systems An information system combines information technology, people, and data to support business requirements

Systems Development Business information systems are developed by people who are technically qualified, business-oriented, and highly motivated. Successful developers also must be good communicators with strong analytical and critical thinking skills. Traditionally, a company either developed its own information systems, called in-house applications, or purchased systems called software packages from outside vendors

The Benefits of IS Handle daily business transactions, Improve company productivity Help managers make sound decisions.

fig_03_01 C H A P T E R 1 THE SYSTEMS ANALYST AND INFORMATION SYSTEMS DEVELOPMENT INTRODUCTION The systems development life cycle (SDLC) is the process of understanding how an information system (IS) can support business needs, designing the system, building it, and delivering it to users. Example : In 2005, an estimated $1 trillion was spent by organizations and governments on IT hardware, software, and services worldwide.  5%–15% were abandoned as hopelessly inadequate, before or shortly after delivery.  Many of the systems that aren’t abandoned are delivered to the users significantly late.  cost far more than expected, and have fewer features than originally planned.

fig_03_01 C H A P T E R 1 THE SYSTEMS ANALYST AND INFORMATION SYSTEMS DEVELOPMENT Systems Analyst: The key person in the SDLC who analyzes the business situation, identifies opportunities for improvements, and designs an information system to implement the improvements.  The primary objective of the systems analyst is not to create a wonderful system. The primary goal is to create value for the organization, which for most companies means increasing profits.  the goal is to enable the organization to perform work better so that it can earn greater profits

Components of IS

Components Hardware is the physical components within a computer system Software is set of instructions,written in a specialized language, the execution of which controls the operation of the computer. Data is the raw facts that may have no meaningful idea and will be transformed to Information by the IS People are persons who will be affected by the IS Processes describe the tasks and business functions that users, managers, and IT staff members perform to achieve specific results.

Recently New companies have appeared that are specialized in IT development and IS consultancy E Commerce: B2C: Business to Consumer ( Ebay & Amazon) B2B : Business to Business

Business Functions

SDLC Phases Planning Phase: The planning phase is the fundamental process of understanding why an information system should be built and determining how the project team will go about building it. Analysis PhaseThe purpose of the systems analysis phase is to build a logical model of the new system Design Phase : The design phase decides how the system will operate in terms of the hardware, software, and network infrastructure that will be in place. the user interface, forms, reports that will be used; the specific programs, databases, and files that will be needed Implementation Phase:During the systems implementation phase, the new system is constructed
