Introduction To Requirements Analysis And Design Definition

Defining requirements architecture implies structuring all of the requirements so that they support each other and contribute to accomplishing overall business objectives.

The requirements architecture is the framework that consists of all of the change requirements. All of the individual requirements within this structure must be cohesive and complement each other so they can produce value to the stakeholders.

The requirements infrastructure is used to gain a better understanding of the models and their fit to the solution scope, help organise those requirements, illustrate models interaction and mutual relationship, and contribute to decision making in reaching the organisational goals.

The key inputs for defining requirement architecture are information management approach, requirements of any state, and solution scope. The main output is organised requirements architecture.

This task includes the following elements:

• Requirements Viewpoints and Views
• Template Architectures
• Completeness
• Relating and Verifying Requirements Relationships
• Business Analysis Information Architecture

The guidelines and tools of use for this task are architecture management software, legal/regulatory information, and methodologies and frameworks. The techniques business analysts usually employ are:

Data Modelling

• Functional Decomposition
• Interviews
• Organisational Modelling
• Scope Modelling
• Workshops

The key stakeholders for this part of the business analysis process are domain subject matter expert, implementation subject matter expert, project manager, sponsor, tester, and any other stakeholder who may use requirements architecture.
