Final Paper/Presentation |
Learn history and issues about client
- Evaluate public sources, such as newspapers, the internet and local and/or
Identify similar systems
Identify basic characteristics of that type of system
- Raw Materials
Develop questions for client
Interview Client and Stakeholders
Identify client’s perception of the problems
Identify client’s goals, requirements and expectations
Review systems, manuals, forms and other written materials
Identify system characteristics (Inputs, Outputs, Processes, Stakeholders)
Identify stakeholders’ perspectives
Determine client’s perception of solutions
Determine stakeholders’ perceptions of solutions
- current system description
- current deficiencies
Identify problems and opportunities
- from your analysis
- from client’s perception
- from stakeholders’ perceptions
Create data flow diagram of current system
Create written description of the situation
Define scope of proposed system in terms of its functions, users, dimensions and constraints
Define and document possible types of solutions
Examine the costs of similar systems.
Produce a rough estimate of the system size, costs, schedules, etc.
Evaluate gross estimates of costs and benefits for various solutions
Evaluate business need for various systems
Compare the business needs and the cost/benefit analyses of systems
Propose one or more systems – provide brief descriptions of systems, needs and costs/benefits
Refine environmental influence document
Refine system description
Identify deliverables of proposed solutions
Proposed tentative schedule for the delivery of key stage deliverables
Define the benefits of the system. Include both quantitative and qualitative measures
Refine proposed system description
Present potential systems to client for review
Present potential systems to stakeholders for review
Further analyze system
Refine the scope of the new system
Determine issues for consideration
- their uses of the current system
- perceived deficiencies of the current system
- their requirements for the new system.
Interview (or use questionnaire) with all users and stakeholders
Develop detailed set of user-specified requirements for the new system
Summarize and critique new system requirements.
- prioritized user requirements
- resolution of current system's deficiencies.
Develop a list of benefits.
- Include both tangible and intangible benefits and costs
- Include both quantitative and qualitative benefits and costs
Produce detailed estimate of costs, schedules, resources, and the like, including a schedule for the production of major deliverables.
Refine System description
Identify Data requirements
Identify Network and telecommunications requirements
Identify System controls (password access, recovery/restart, etc.)
Identify Revised cost/benefit analysis and payback schedule
Identify Estimates of the next stage and remainder of project
Identify potential risks associated with the plan
Refine the system description
Consider the physical, environmental, and operational constraints into system constraints.
Evaluate possibilities such as on-line, transation-based, distributed, centralized, terminals, workstations, etc.
Draw diagrams of proposed system (including data flow and entity-relationship diagrams)
- Create data flow diagrams of proposed system
- Create use case diagrams of proposed system
- Create entity-relationship of proposed system
Develop system data dictionary
Document all interfunction and interdata relationships
Ensure compatibility with corporate systems
Review and expand cost-benefit analysis
Produce system specifications document
Review system specification document with client and stakeholders
Review prototype with client and stakeholders
Refine alternative system descriptions
Refine data requirements
Refine technical specifications
Refine cost-benefit analysis
Recommended design alternatives: prototyping techniques, phased development, etc.
Recommended implementation techniques, self code purchased packages, or external development
Develop system test plan
Identify system controls
