Study Notes

System Acquisition and Development Methodologies

Learning outcomes for this chapter: Students will be able to conceptualize a systematic approach to System Acquisition, review phase-wise activities, understand software procurement, evaluate IT proposals, analyze current systems, compare SDLC models, and know advantages/disadvantages of system development models.

Chapter Overview

Information systems are crucial in modern business, connecting people and various systems.
Learning outcomes are to conceptualize system acquisition, understand software procurement, analyze current systems, compare and contrast SDLC models, and know the advantages/disadvantages of various systems development models.

Information System Acquisition

Acquisition Standards: Security, reliability, and functionality built into hardware/software.
- Ensuring existing system compatibility.
- Vendor contract reviews and licensing.
- Bids for hardware/software acquisition.
- Bidding procedures for hardware/software acquisition.
Acquiring components: Organizations need hardware, software, and services for system functionality.
- Options for acquisition: Purchase, lease, or rent.
- System acquisition committee to ensure timely/effective completion.
- Requests for Proposal (RFP) stages to solicit proposals from vendors.

Methods of Validating Proposals

Checklists: A straightforward method to evaluate, using predetermined questions for vendor responses, including software/hardware aspects.
Point-Scoring Analysis: An objective method to identify matching user needs with software capabilities, including data processing needs, vendor reputation, and costs.

Hardware/Software Acquisition

Hardware acquisition: Selection techniques based on criteria like machine tools, transportation, etc. Management needs to depend on vendors for support/implementation/training.
Software Acquisition: Systems analysis should define the nature of the application software, whether in-house development or vendor purchase, based on the system's workload.

Contracts and Legal Considerations

Contracts: Outline responsibilities, performance assurances, source code accessibility, software/data security, and other important issues.
Licensing: Define the rights to use software, and comply with legal restrictions (e.g., GDPR).
Copyright Violation: Avoid using unlicensed software and understand licensing agreements to prevent legal issues.
Vendor Validation: Evaluate software/hardware's compatibility with existing systems, costs, and benefits, plus overall maintainability and vendor support.

System Acquisition Cycle

Defining System Requirements: Identify system objectives and business goals, details on input, processing, and output data.
Identifying Alternatives: List options like off-the-shelf software, purchased packages, in-house development, or outsourcing.
Feasibility Analysis: Assess technical, economic, and operational feasibility for various alternatives.
Risk Analysis: Review system security and vulnerabilities, and evaluate potential impacts.
Selection Process: Choose the best alternative, balancing requirements, cost, and other factors.
Procurement of Software: Negotiate contract terms, including functionality specifications, hardware, and intellectual property rights.
Completing Final Acceptance: Verify that the system functions as per the agreement. Ensure contracts address price, conditions, and any technical support terms.

Methodologies

Waterfall: Sequence of steps, one must complete before the next one starts.
- Advantages include resource conservation.
- Disadvantages include rigidity, inflexibility, and difficulty changing course.
Prototyping: Development of a preliminary version to gather user feedback.
- Advantages include customer involvement and flexibility.
- Disadvantages include potential behavioral changes, potential risk in changing requirements.
Incremental: Combine elements of traditional and iterative methods, developing smaller parts of the application, one at a time.
- Advantages include flexibility and rapid delivery.
- Disadvantages include potential issues in handling system architecture.
Spiral: Combines top-down and bottom-up ideas. Intended for complex projects and allows for risk analysis.
- Advantages include addressing risks early and making adjustments based on feedback.
- Disadvantages include complexity and possibly difficulty demonstrating early success to management.
Rapid Application Development (RAD): Minimal planning and rapid prototyping.
- Advantages include fast development and lower costs.
- Disadvantages include potential quality issues and more complex projects.
Agile: Iterative and incremental approach, flexible, responsive to changes, and highly collaborative.
- Advantages include strong user involvement, flexibility, and early feedback.
- Disadvantages include potential issues with project documentation and possible lack of structure.
