Today’s Schedule

Project Management– Scoping & Planning– Risks & Feasibility

Thursday, Quiz #1 on Chapters 1 & 2 Assignment #3 Due Monday, January 29th Begin Reading Chapter 4, page 110 - 120

System Requirements

Defining the Problem

Review business needs– Use strategic plan documents – Consult key users – Develop list of expected business benefits

Identify expected system capabilities– Define scope in terms of requirements

Create system scope document Build proof of concept prototype Create context diagram

Producing the Project Schedule

Develop work breakdown structure (WBS)– List of tasks and duration required for project– Similar to outline for research paper– WBS is foundation for project schedule

Build a PERT/CPM chart– Assists in assigning tasks– Critical path method– Gantt chart and tracking GANTT chart

Confirming Project Feasibility

Risk management Economic feasibility

– Cost/benefit analysis– Sources of funds (cash flow, long-term capital)

Organizational and cultural feasibility Technological feasibility Schedule feasibility Resource feasibility

Economic Feasibility

Cost/benefit analysis – Estimate project development costs– Estimate operational costs after project– Estimate financial benefits based on annual savings

and increased revenues– Calculate using table of costs and benefits

Uses net present value (NPV), payback period, return on investment (ROI) techniques

Intangibles in Economic Feasibility

Intangible benefits cannot be measured in dollars– Increased levels of service

– Customer satisfaction

– Survival

– Need to develop in-house expertise

Intangible costs cannot be measured in dollars– Reduced employee morale

– Lost productivity

– Lost customers or sales
