  17. Creating Business Models • Three major areas normally require business models • Business events • Business processes • Information repositories and flows • Business models tied to system requirements • Model format and rigor vary with each project Object-Oriented Analysis and Design with the Unified Process

  18. Environment and the Inception Phase • Discipline concerned with development environment • Several activities are included • Select and configure the development tools • IDEs and CASE • Tailor the UP development process • Defining the rigor of a project • Provide technical support services Object-Oriented Analysis and Design with the Unified Process

  19. Figure 3-7 Sample Criteria for Defining Rigor of Project Controls Object-Oriented Analysis and Design with the Unified Process

  20. Finalizing the System and Project Scope • System scope: defines capabilities of new system • Project scope: describes how project is to be built • Provides disposition toward staff training • Provides data conversion information • Sets parameters for quality control • System scope is part of the larger project scope • Essential use case model helps delineate scope • Essential use case list attached to the project Object-Oriented Analysis and Design with the Unified Process

  21. Figure 3-8 System Scope and Project Scope Object-Oriented Analysis and Design with the Unified Process

  22. Figure 3-9 Sample Essential Use Case List for RMO Object-Oriented Analysis and Design with the Unified Process

  23. Developing the Project and Iteration Schedule • Development team sets schedule for project and iterations • Tasks involved in scheduling: • Develop the work breakdown structure (WBS) • Develop the schedule • Develop resource requirements and staffing plan Object-Oriented Analysis and Design with the Unified Process

  24. Developing the WBS • Two general approaches for building a WBS • By deliverable timeline • By a sequential timeline • Four techniques for identifying WBS tasks • Top-down: Identify major activities first • Bottom-Up: List all tasks first and organize later • Template: Use standard template of tasks • Analogy: Copy tasks of similar completed project Object-Oriented Analysis and Design with the Unified Process

  25. Developing the Schedule • Project schedule orders all activities and tasks • Building the schedule • Identify dependencies between the tasks on WBS • Estimate the effort that each task will require • Dependencies: identify related tasks • Finish-start relationships • Start-start relationships • Finish-finish relationships • Scheduling tool: Microsoft Project Object-Oriented Analysis and Design with the Unified Process

  26. Entering the WBS into MS Project • Two types of charts used to show project schedule • PERT/CPM chart • Gantt chart • Charts show same information in different formats • Key metrics • Critical path • Slack time, or float • Milestones Object-Oriented Analysis and Design with the Unified Process

  35. Evaluating the Technological Feasibility • Staffing should have technological proficiency • Solutions to problem are straightforward • Provide additional training • Hire consultants • Hire more experienced employees • Possibly alter scope and approach of the project • Realistic assessments speedup corrective response Object-Oriented Analysis and Design with the Unified Process

  36. Determining the Schedule Feasibility • Development of project schedule involves high risk • Assumptions and estimates made without adequate information • Adaptive projects very susceptible to schedule risks • Project managers use milestones to evaluate pace and compensate for slippage • Contingency plans help reduce the risk of slippage Object-Oriented Analysis and Design with the Unified Process

  37. Assessing the Resource Feasibility • Human and other resources to assess • Primary resource consists of team members • Systems analysts, system technicians, users • Support staff • Computer resources and physical facilities • Factors adversely impacting human resource • Lack of required people skill sets • Relocations or departures Object-Oriented Analysis and Design with the Unified Process

  38. Determining the Economic Feasibility • Economic feasibility consists of two questions • Does anticipated value of benefits exceed project costs? • Is there adequate cash flow to fund the project? • Cost/benefit analysis determines economic feasibility • Developing cost/benefit analysis is a three-step process • Estimate anticipated development and operational costs • Estimate the anticipated financial benefits • Subtract costs from benefits • MS Project supports cost/benefit analysis Object-Oriented Analysis and Design with the Unified Process
