Requirements Analysis.

1
Requirements Analysis

Requirements Analysis
• It is an process for gathering
requirements for developing software. it
is done in the planning phase of the
project
2

What it provides
It provides software designers following
information regarding the development
process:
•Information about the software
•Functionality of the software
•Behaviour of the software
3

Why it is required
Detailed information about the system
that is collected in this phase helps
developers to interpret Model to data,
architectural, and designs done at
component-level
4

5
Objectives of Analysis
• Identify customer’s requirements identification
• feasibility evaluation of system
• economic and technical analysis
• Assign functions to the elements of the system
• schedule and constraints design
• system definitions development

6
Software Requirements Analysis
Phases
• Problem recognition
• Evaluation and synthesis
• Specification
• Review
• Modeling

7
Components of Requirements
Analysis
Feasibility Study:
•Economic feasibility
– cost/benefit analysis
•Technical feasibility
– hardware/software/people

8
Components of Requirements
Analysis
Feasibility Study:
•Legal feasibility
•Alternatives
– in how many ways the design is possible to
complete

9
System Specification
• Introduction
• Functional data explanation
• Subsystem description
• System modeling
• System simulation
• Products
• Appendices

10
Analysis Principles
• Proper analysis of technology domain
• Models should represent detailed information
about the system along with functions and
behavior
• Analysis should lead to details of system
implementation from defining essential
system information
• Analysis should be traceable
