Difference between System Analysis and Design

1.Overview of System Analysis and Design

        In business, System Analysis and Design refers to the process of examining a business situation with the intent of improving it through better procedures and methods. System Analysis and Design relates to shaping organizations, improving performance and achieving objectives for profitability and growth.

        System Development can be generally being thought of as having two major components : Systems Analysis and System Design. System Design is the process of planning a new business system or one to replace or complement an existing system. System analysis is the process of planning a new business system or one to replace or complement an existing system. System analysis is the process of gathering and interpreting facts, diagnosing problems, and using the information to recommend improvements to the system.

1.1. Introduction to System Analysis and Design

• Systems analysis and design is a process that many companies use to evaluate particular business situations and develop ways to improve them through more optimal methods. Companies may use this process to reshape their organization or meet business objectives related to growth and profitability. System analysis and design also typically emphasize how systems act, their relationships to other subsystems and the ability of the both to meet a specific goal. This often involves analyzing a system's performance and the quality of its output.

• System Analysis: It is a process of collection and interpreting facts, identifying the problems, and decomposition of a system into its components. System analysis is conducted for the purpose of studying a system or its parts in order to identify its objectives. It is a problem solving technique that improves the system and ensures that all the components of the system work efficiently to accomplish their purpose. 

          Note: Analysis specifies what the system should do

• System Design: It is a process of planning a new business system or replacing an existing system by defining its components or modules to satisfy the specific requirements. Before planning, you need to understand the old system thoroughly and determine how computers can best be used in order to operate efficiently

          Note: System Design focuses on how to accomplish the objective of the system

1.2.1. System Analysis

• System Analysis is a process of collecting and interpreting facts, identifying the problems, and decomposition of a system into its components.
• System Analysis is conducted for the purpose of studying a system or its parts in order to identify its objectives.
• System Analysis is the examination of the problem.
• It is concerned with identifying all contains.
• It deals with data collection and datelined evaluation of existing file.
• In System Analysis part the main focus is on data flow diagram and data dictionary.
• System Analysis analyze the problem and examine it to find out the solutions.

1.2.2. System Design

• System Design is the process of planning a new business system or replacing an existing system by defining its components or modules to satisfy the specific requirements.
• In System Design, a personnel needs to understand the old system thoroughly and determine how computers can be best used in order to operate efficiently.
• System Design is the creator of information system which is solution to the program.
• It is concerned with erudition of the activities for a particular system goal.
• It deals with general design specification detailed design specification I/O files procedures.
• In System Design, the main focus is on program construction testing and user acceptance.
• System Design provides technical specification and reports by which problems can be trapped.
