Task 1 of 3 Presentation and speaker notes Instructions
- In your presentation, you need to explain various components of systems analysis and further explain how systems analysis and design fits into the software development life-cycle.
- In the later part of the presentation, evaluate different approaches to system analysis and design. You will also require to evaluate system design requirements of Natixis.
(ACs 1.1, 1.2, 1.3, 1.4)
Delivery and Submission
- 1x Presentation file (including references)
- 1x Speaker notes (circa 800 words)

Sample Answer
The Role of Systems Analysis and Design in the Software Development Life Cycle
Systems analysis and design (SA&D) is a core component of the Software Development Life Cycle (SDLC), ensuring that IT systems meet user requirements, organisational goals, and industry standards. In the SDLC, SA&D typically follows the initial planning phase and precedes coding, testing, and deployment. It acts as a bridge between stakeholder needs and technical implementation, ensuring effective transformation of business requirements into functional systems.
Systems Analysis and Its Components
Systems analysis is the process of collecting and interpreting facts, identifying problems, and decomposing a system into its components to understand its structure and functions. Its key components include:
-
Requirements Elicitation: Involves gathering requirements from stakeholders through interviews, surveys, and observations to understand what the system should achieve (Dennis et al., 2018).
-
Feasibility Study: Assesses the technical, operational, and economic viability of proposed solutions (Avison & Fitzgerald, 2006).
-
Process Modelling: Utilises tools such as Data Flow Diagrams (DFDs) and Entity-Relationship Diagrams (ERDs) to visually represent system functions and data relationships.
-
System Specification: Converts gathered data into structured specifications that guide system design and implementation.
Systems Design and Its Requirements
System design involves defining the architecture, modules, interfaces, and data for a system to satisfy specified requirements. It includes:
-
Logical Design: Focuses on the flow of data, inputs, and outputs independent of physical implementation.
-
Physical Design: Specifies actual input devices, storage media, and system software.
-
Security and Control Design: Ensures that data integrity, confidentiality, and availability are upheld.
At NatAxis, for instance, designing a secure investment management system must adhere to regulatory standards and ensure data protection for millions of clients, making thorough system design a critical requirement.
