Systems analysis is the second step in the Systems Design Life Cycle (SDLC), which is a process for planning, creating, testing, and deploying an information system. Systems analysis involves gathering and analyzing the requirements of the system, such as the user needs, the business objectives, and the functional specifications. Systems analysis also involves modeling the system using various techniques, such as data flow diagrams, entity-relationship diagrams, and use case diagrams. Systems analysis helps to define the scope and boundaries of the system, as well as the inputs, outputs, processes, and data structures. Systems analysis is essential for ensuring that the system design meets the expectations and needs of the stakeholders. References: 1, 2, 3, 4

When deciding on system alternatives, the IT manager has to consider the following points1:

• Technological feasibility: The IT manager has to assess whether the proposed system can be implemented with the available technology, resources, and skills. The IT manager has to evaluate the technical risks, challenges, and benefits of each alternative.
• Organizational impact: The IT manager has to analyze how the proposed system will affect the organization’s structure, culture, processes, and performance. The IT manager has to consider the stakeholders’ needs, expectations, and resistance to change. The IT manager has to ensure that the system aligns with the organization’s vision, mission, and goals.
• Financial constraints: The IT manager has to estimate the costs and benefits of each alternative, including the initial investment, operating expenses, maintenance costs, and return on investment. The IT manager has to compare the alternatives based on their financial viability and value for money. The IT manager has to secure the necessary funding and budget for the system. References: 1: EXIN EPI Certified InformationTechnology Manager, Module 6: IT Project Management, Section 6.3: System Analysis and Design, Page 6-11.

A byte is the smallest unit of data storage that consists of eight bits. A bit is a binary digit that can have two values: 0 or 1. A byte can store one character, such as a letter, a number, or a symbol. An octet is another name for a byte, but it is not commonly used. A character is a symbol that represents a letter, a digit, or a punctuation mark, but it is not a unit of data storage. A field is a group of bytes that stores a specific type of data, such as a name, a date, or a number, but it is not the smallest unit of data storage. References: Data Storage Units of Measurement Table, What are the units of measurements for data storage?, Data Storage Units
