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.
