Identifying and Selecting
Projects
Requests for IS development comes
from 3 sources of projects
1. Management and business units
2. Managers who want to make a system
more efficient
3. Formal planning groups
3.4
Two Primary Tasks in System
Planning & Selection Phase
Identifying and selecting Projects
Initiating and Planning Projects
Identifying and Selecting
Projects: 3 activities
1. Projects are identified by

Top management
 Steering committee: a cross section of mgrs
 User departments
 Development group or senior IS staffs/mgrs

Top-Down Identification

Senior management or steering committee
 Focus is on global needs of organization
3.6
Identifying and Selecting
Projects – 3 activities

Bottom-Up Identification


Business unit or IS group
Don’t reflect overall goals of the organization
2. Classify and rank development projects by




Top management
Steering committee
User departments
Development group or senior IS
staffs/managers
Identifying and Selecting
Projects – 3 activities
3. Select IS development projects need
to consider 6 factors:






3.8
Perceived needs of the organization
Existing systems and ongoing projects
Resources available
Evaluation criteria
Current business conditions
Perspectives of the decision makers

Identifying and Selecting
Projects
Deliverables and outcomes


Primary deliverable of this phase is a
schedule of specific IS development
projects

1. Assessing Economic
Feasibility
Cost – Benefit Analysis
Determine Benefits

Tangible Benefits
 Can be measured easily

3.17
Examples

 Increased management planning and control
1. Assessing Economic
Feasibility

Intangible Benefits
 Cannot be measured easily
 Examples




Increased employee morale
Competitive necessity
More timely information
Promotion of organizational learning and understanding
Determine Costs

Tangible Costs
 Can easily be measured in dollars

3.18
Example: Hardware
3.19
1. Assessing Economic
Feasibility
Determine Costs (Continued)

Intangible Costs
 Cannot be easily measured in dollars or with certainty
 Examples:
 Loss of customer goodwill

Loss of employee morale
 One-Time Costs


3.20
Associated with project startup, initiation and development
Includes
 System Development
 New hardware and software purchases
 User training
 Site preparation
 Data or system conversion
1. Assessing Economic
Feasibility
 Recurring Costs



Associated with ongoing use of the system
Includes:
 Application software maintenance
 Incremental data storage expense
 New software and hardware releases
 Consumable supplies

Feasibility

3.23
Assessment of how a proposed
system solves business problems
or takes advantage of
opportunities
3. Assessing Technical
Feasibility

Assessment of the development
organization’s ability to construct a
proposed system
4. Assessing Schedule
Feasibility

3.25
Assessment of timeframe and
project completion dates with
respect to organization
constraints for affecting change
5. Assessing Legal and
Contractual Feasibility
