Study Notes
System Development Life Cycle (SDLC)
- System development measures the suitability of a system to a company based on economic, technical, operational, and schedule feasibilities.
Feasibility Tests
- Economic feasibility (cost/benefit analysis)
- Technical feasibility
- Operational feasibility
- Schedule feasibility
Documentation
- Collection and summarization of data and information
- Includes reports, diagrams, programs, and other deliverables
Data and Information Gathering Techniques
- Review documentation
- Observe
- Questionnaire
- Interview
- Joint-application design (JAD) session
- Research
Reasons to Create or Modify an Information System (IS)
- To correct problems in existing systems
- To improve existing systems
- Outside groups may mandate change
- Competition can lead to change
Planning Phase
- Begins when the steering committee receives a project request
- Steering committee:
- Reviews and approves project requests
- Prioritizes project requests
- Allocates resources
- Forms project development team for each approved project
Analysis Phase
- Conducts preliminary investigation (feasibility study)
- Performs detailed analysis
- Presents findings in a feasibility report
Preliminary Investigation
- Determines the exact nature of the problem or improvement
- Checks if it's worth pursuing
- Presents findings in a feasibility report
Detailed Analysis
- Studies how the current system works
- Determines user wants, needs, and requirements
- Recommends a solution (logical design)
System Proposal
- Assesses feasibility of each alternative solution
- Recommends the most feasible solution
- Presented to the steering committee for system development decisions
Possible Solutions
- Horizontal market software (meets needs of many companies)
- Vertical market software (designed for a particular industry)
- Writing custom software (developed at user's request)
- Outsourcing (having an outside source develop software)
Design Phase
- Acquires hardware and software, if necessary
- Develops all details of the new or modified information system
Acquiring Hardware and Software
- System Development Life Cycle (SDLC)
- Phase 1: Planning
- Phase 2: Analysis
- Phase 3: Design
- Phase 4: Implementation
- Phase 5: Support
Guidelines for System Development
- Arrange tasks into phases
- Involve users
- Develop clearly defined standards
Participants in System Development
- Systems analyst: responsible for designing and developing information systems
- Users: anyone for whom the system is being built
- Project team: develops the system
Feasibility Study
- Determines the exact nature of the problem or improvement
- Checks if it's worth pursuing
- Presents findings in a feasibility report
Assess the suitability of system development for a company by evaluating economic, technical, operational, and schedule feasibility. This quiz covers the four feasibility tests and their importance in the System Development Life Cycle.
