Study Notes
Requirements Analysis Overview
- Requirements analysis is essential for developing an enterprise information system (EIS).
- Optimized business processes guide decision-making during the analysis.
Participants in Requirements Analysis
- Business Analyst: Reads and writes business process models.
- IT Experts: Include system architects, network administrators, programmers, and developers.
- Data Privacy Officers: Ensure compliance with data protection regulations.
- Key Decision Makers: Board members responsible for strategy and approving requirements.
Role of End Users
- End users, such as employees, customers, and suppliers, are critical in the analysis.
- They provide insights into the practical needs and expectations from the EIS.
- The analysis aims to articulate what these users require from the system.
Perspectives on Requirements
-
Business Requirements: Focus on functions the EIS must provide to achieve strategic objectives.
- Example: If a company aims for just-in-time manufacturing, the EIS must prioritize inventory and supply chain management.
-
System Requirements: Relate to technical capabilities needed for the EIS.
- Considerations include speed, processing power, memory, scalability, compatibility, and security.
-
User Requirements: Gathered from end users to understand how they will interact with the EIS.
- Defined through user stories and use cases, detailing necessary features and user interactions.
Interrelation of Requirements
- Business, system, and user requirements are not separate entities; they overlap and inform one another.
- Understanding the intersection of these requirements leads to a more comprehensive system design.
Process of Requirements Analysis
- The analysis phase can last from weeks to several months, depending on project scope.
- Involves numerous meetings, workshops, interviews, and surveys to collect information.
- Soft skills are invaluable for effective communication and stakeholder engagement.
Deliverables from Requirements Analysis
- The final output is a Requirement Specification document.
- This document details prioritized requirements for the EIS, akin to a job description outlining desired qualifications.
- The specification serves as a basis for evaluating and selecting suitable EIS solutions in the next steps.
