However, before an information system can be implemented, it must be carefully analysed, designed, and documented. These processes ensure that the system meets the needs of users and functions effectively within the organisation.
LA-NET | ONLINE LEARNING VIDEO PLATFORM FOR POST-SECONDARY & HIGHER INSTITUTION STUDENTS The aim of this Series is to introduce you to the fundamental concepts of systems analysis, design, and documentation, and to equip you with the skills needed to evaluate and prepare information systems for practical use. We shall commence this Series by examining the concept of systems analysis, including its definition, purpose, and steps. Next, we will explore the principles of systems design, highlighting its importance and characteristics. Finally, we will wrap up by considering the documentation of information systems, focusing on its meaning, role, and types. Series Learning Outcomes Upon completing this Series, you should be able to: SLO 1.1 define systems analysis and explain its purpose, SLO 1.2 describe the steps involved in systems analysis, SLO 1.3 explain the principles and importance of systems design, SLO 1.4 identify the characteristics of effective systems design, SLO 1.5 define documentation in information systems and explain its role, SLO 1.6 distinguish between different types of documentation used in information systems. 1.1 Concept Of Systems Analysis 1.1.1 Definition and purpose of systems analysis Systems analysis is the process of studying an existing system to identify its components, relationships, and problems, with the aim of improving or designing a new system. It involves examining how data flows, how processes are carried out, and how information is used within an organisation. The purpose of systems analysis is to ensure that information systems meet the needs of users and support organisational objectives. It helps to identify inefficiencies, clarify requirements, and provide a foundation for effective system design. Fill in the blank: Systems analysis is the process of studying an existing system to identify its ______ and problems.
LA-NET | ONLINE LEARNING VIDEO PLATFORM FOR POST-SECONDARY & HIGHER INSTITUTION STUDENTS Figure 1.1: Basic flow of systems analysis 1.1.2 Steps in systems analysis Systems analysis typically follows a structured approach. The main steps include: Problem identification: Recognising issues or inefficiencies in the current system. Requirement gathering: Collecting information about what users need from the system. Feasibility study: Assessing whether the proposed system is practical and cost-effective. System modelling: Representing processes and data flows using diagrams and models. Evaluation: Reviewing findings to ensure they align with organisational goals.
LA-NET | ONLINE LEARNING VIDEO PLATFORM FOR POST-SECONDARY & HIGHER INSTITUTION STUDENTS These steps provide a logical pathway for moving from understanding the current system to preparing for system design. Fill in the blank: The feasibility study in systems analysis assesses whether the proposed system is ______ and cost-effective. Box 1.1: Steps in systems analysis Pilot questions 1.1
LA-NET | ONLINE LEARNING VIDEO PLATFORM FOR POST-SECONDARY & HIGHER INSTITUTION STUDENTS Systems analysis is primarily concerned with: Designing hardware components Studying existing systems to identify problems and requirements Writing computer programs Marketing information systems Which of the following is a key purpose of systems analysis? To increase costs To ensure systems meet user needs To eliminate documentation To avoid feasibility studies The feasibility study in systems analysis focuses on: Identifying inefficiencies only Assessing practicality and cost-effectiveness Writing system documentation Marketing new systems Which step of systems analysis involves representing processes and data flows using diagrams? Problem identification Requirement gathering System modelling Evaluation Requirement gathering in systems analysis involves: Collecting information about user needs Designing hardware components Writing feasibility reports Marketing system outputs 1.2 Principles Of Systems Design 1.2.1 Definition and importance of systems design Systems design is the process of defining the architecture, components, modules, interfaces, and data for a system to satisfy specified requirements. It translates the findings from systems analysis into a structured plan that guides the development and implementation of the system.
LA-NET | ONLINE LEARNING VIDEO PLATFORM FOR POST-SECONDARY & HIGHER INSTITUTION STUDENTS The importance of systems design lies in its ability to ensure that the system is efficient, user-friendly, and aligned with organisational goals. A well-designed system reduces errors, improves productivity, and supports decision-making. Fill in the blank: Systems design translates the findings from systems analysis into a structured ______ for development and implementation. Figure 1.2: Transition from analysis to design to implementation 1.2.2 Characteristics of effective systems design
LA-NET | ONLINE LEARNING VIDEO PLATFORM FOR POST-SECONDARY & HIGHER INSTITUTION STUDENTS Effective systems design should possess several key characteristics: Simplicity: The design should be straightforward and easy to understand. Flexibility: It should allow for modifications and future expansion. Reliability: The system must perform consistently and accurately. Efficiency: Resources such as time, cost, and computing power should be optimally utilised. User orientation: The design should meet the needs of users and be easy to operate. These characteristics ensure that the system not only functions correctly but also remains sustainable and adaptable in the long term. Fill in the blank: One of the characteristics of effective systems design is ______, which ensures the system can be modified or expanded. Box 1.2: Characteristics of effective systems design
