Study Notes
System Acquisition and Development
- Organizations can choose between buying off-the-shelf software or custom development, with purchased software offering lower risk and faster deployment.
- Maintenance costs for commercial software can be high.
Waterfall System Development Process
- A structured sequential process featuring six key phases: Investigation, Analysis, Design, Construction, Integration, Testing, and Implementation.
- Each phase requires completion and approval before proceeding to the next.
System Investigation
- First phase focuses on understanding the problem or opportunity driving the system's development.
- Key steps include reviewing systems investigation requests, identifying team members, budgeting, performing feasibility analysis, and preparing reports.
Steps of System Investigation
- Review Request: Evaluates the initial problem statement and aligns it with organizational goals.
- Team Recruitment: Assembles a team to gather data and prepare reports.
- Budget Development: Creates a schedule and budget considering major milestones and resources.
- Perform Investigation: Defines high-level business requirements and identifies project risks.
Joint Application Development (JAD)
- A structured meeting process designed to enhance efficiency in the investigation and design phases.
Feasibility Analysis Components
- Technical Feasibility: Checks if the project fits existing technology limits.
- Economic Feasibility: Evaluates if project benefits outweigh costs.
- Legal Feasibility: Assesses potential legal restrictions.
- Operational Feasibility: Examines acceptance and performance expectations of the system.
- Schedule Feasibility: Determines if the project's timeline is achievable.
System Analysis
- Emphasizes gathering data on the current system, determining new requirements, and assessing alternative solutions.
- Steps include recruiting, budgeting, studying existing systems, prioritizing requirements, evaluating solutions, and preparing reports.
Key Focus Areas in System Analysis
- Analyze existing system strengths and weaknesses using data collection methods like JAD, direct observation, and surveys.
- Develop prioritized requirements classified as critical, medium, or low priority, and utilize Data-Flow Diagrams (DFDs) for modeling.
Security and Performance in System Analysis
- System performance factors include output timeliness, ease of use, scalability, response time, availability, and reliability.
- Data modeling principles establish relationships among data entities using Entity-Relationship (ER) diagrams.
Identifying Alternatives and Reporting
- Teams must creatively consider various solutions while applying the Pareto principle (80-20 rule) to prioritize analysis.
- Conclusions presented in a formal systems analysis report that provides recommendations for the project's next steps.
System Design Phase
- This phase formulates technical specifications for building the system.
- Key activities entail assembling the design team, scheduling, budgeting, designing user interfaces, security measures, disaster recovery plans, and databases.
