Study Notes

Learning Objectives

Assess cost/benefit analyses for strategic IT planning.
Identify four business decisions for acquiring new applications.
Understand six key processes in the systems development life cycle (SDLC).
Explore alternative development methods and supporting tools.

IT Planning

Aligns with the organizational strategic plan.
Involves creating a comprehensive IT architecture.
Managed by an IT steering committee to guide IS operational planning.

IT Strategic Plan

Must align with organizational goals.
Provides seamless networking for users, applications, and databases.
Allocates resources efficiently to compete among projects, ensuring timely and functional completion.

IS Operational Plan Components

Includes a mission statement for the IS function.
Describes the IS environment and objectives.

Evaluating IT Investment

Assess costs and benefits to determine investment viability.
Conduct cost-benefit analyses through various methods:
- Net Present Value (NPV)
- Return on Investment (ROI)
- Break-even analysis
- Business case approach

Challenges in Assessing IT Costs

Problems include uncertainty in long-term impacts and changes in technology.
Intangible benefits, like enhanced productivity or employee satisfaction, are hard to quantify.

Strategies for Acquiring IT Applications

Determine payment structures and ease of use for the applications.

Traditional Systems Development Life Cycle (SDLC) Stages

Stages include:
- Systems investigation
- Systems analysis
- Systems design
- Programming and testing
- Implementation
- Operation and maintenance

Teams in the Traditional SDLC

Collaborates with users, systems analysts, programmers, technical specialists, and stakeholders.

SDLC: Systems Investigation

Options include:
- No change to current systems.
- Enhance or modify existing systems.
- Develop a completely new system.
Conduct a feasibility study considering:
- Technical feasibility
- Economic feasibility
- Behavioral feasibility
Steering committees make go/no-go decisions based on feasibility studies.

SDLC: Systems Analysis

Analysts assess business problems to be solved by the new IS.
Deliverable includes a comprehensive set of system/user requirements.
