Identifying and Selecting IS Development Projects
• Sources of projects– Management and business units– Managers who want to make a system more efficient or less costly– Formal planning groups
• Top-Down Identification– Senior management or steering committee– Focus is on global needs of organization
• Bottom-up Identification– Business unit or IS group– Don’t reflect overall goals of the organization

Corporate and Information Systems Planning
• Need for planning– Improperly planned projects result in systems
that cannot be shared across an organization– As business processes change, lack of
integration will hamper strategy and business process changes

• ISP must look at information systems and technologies in terms of how they help the business achieve its objectives defined during corporate strategic planning.
• Parallel activities of CSP and ISP

Initiating and Planning System Development Projects
• Project Initiation– Establishment of project team– Development of relationship with customer– Project Initiation Plan– Establishment of Management Procedures– Establishment of Project Workbook and Project
Management Environment
• Project Planning = Survey Phase– Defining clear, discrete activities and the work needed
to complete each activity

• Deliverables and Outcomes– Baseline Project Plan (BPP)
• Scope
• Benefits
• Costs
• Risks
• Resources
– Statement of Work (SOW)• Describes deliverables
• Outlines work needed to be performed
