Define Requirements Approach & Project Scope (5%) Flashcards
What is a requirement?
“A feature/characteristic that the business users need the new system (business or IT) to provide”
What are the 5 stages of the Requirement Engineering Framework
- Requirements Elicitation
- Requirements Analysis
- Requirements Validation
- Requirements Documentation
- Requirements Management
The framework is: iterative not sequential
What is the relationship between Elicitation/Analysis/Validation
Elicitation - Information about requirements
Analysis - Improves the quality: generates gaps and questions and determines if more elicitation needs to take place. Analysis produces defined requirements
Validation - Are we willing to accept these requirements/benchmark them? Any issues identified during validation pushes them back into analysis
What is the rationale for Requirements Engineering?
- Focuses on defining the ideal characteristics of the product/service that will solve a business problem
- The change must be measured & tracked through the project back into BAU
- Help us to move from AS IS to TO BE
Why do Requirements Arise?
- Business changes (operational/business process change) i.e. growth
- Strategic change
- New business, products, business rules or regulations
- Opportunities for improvement
- Competition
What should be considered when planning the requirement approach?
Requirement work must always be conducted pragmatically & RE framework is intended to be as flexible as the situation demands
- Organisational standards
- Project approach
- Types of Requirement (i.e. is NFR needed?
- Nature of the solution (COTS vs Bespoke)
What are the 3 Business Inputs to Requirements?
- Business Case (investigate feasibility)
- Terms of Reference (define the project framework)
- PiD (Initiate the project)
Who creates The Business Case / What does it contain?
Created by: Business representative
What does it contain: Justifies investment / Provides options / Measures of success
Who creates Terms of Reference (ToR) / What does it contain?
Created by: Project team/representatives
What does it contain: structured way of defining the key components (a time) for a project
O - Objectives
S - Scope
C - Constraints
A - Authority & Assumptions
R - Resources
Who creates PID / What does it contain?
Created by: Project manager
What does it contain: (6 Ws) What/why/where/who/when .. of the project
Basis for management of the project & assessment of overall success
