Study Notes
Systems Analysis
- Systems analysis is the initial stage in the systems development life cycle (SDLC) where an organization's total information system needs are analyzed and arranged.
System Planning
- Definition: Identifying problems, opportunities, and resolving them in an organization's information system.
- Key components: understanding user requirements, system requirements, and current system problems.
Initial Investigation
- Definition: Understanding the existing system and gathering details to improve it.
- Methods: user interviews, system documentation review, and system walkthroughs.
Project Scheduling
- Importance: A mechanism to communicate tasks, resources, and timeframes.
- Tools: Gantt charts, Critical Path Method (CPM), and Program Evaluation Review Technique (PERT).
- Components: task identification, resource allocation, and timeframe definition.
Requirement Analysis
- Definition: Determining the needs or conditions for a new or altered product.
- Key steps: user communication, feature expectation determination, conflict resolution, and documentation.
Types of Requirements
Functional Requirements
- Definition: Primary things expected from the software for it to function.
- Examples: user authentication, data input validation.
Non-Functional Requirements
- Definition: Referring to the operation of the system rather than specific behaviors.
- Examples: security, usability.
Business Requirements
- Definition: High-level declarations of organizational goals or needs.
- Examples: increase sales by 10%, improve customer satisfaction.
Requirement Gathering Methods
- Common methods: interviews, surveys, use cases, prototyping, document analysis, and focus groups.
Feasibility Study
- Definition: Assessment of the practicality of a proposed project or system.
- Types of feasibility: technical, economic, legal, operational, and schedule.
Steps of Feasibility Study
- Steps involved:
- Define the problem: clearly identify the issue or need.
- Assess the feasibility: evaluate different aspects of feasibility.
- Propose the alternatives: identify possible solutions or approaches.
- Make the final recommendations: choose the best alternative based on the assessment.
Cost/Benefit Analysis
- Definition: Process to analyze the benefits and costs associated with a decision.
- Common methods: payback method, net present value (NPV) method.
Learn about System Planning in the context of Systems Analysis, including its definition, objective, and key components. Understand the importance of analyzing an organization's information system needs and identifying problems and opportunities for resolution.
