  • D) Activity Diagram

Answer: C) Traceability Matrix

Explanation: A traceability matrix is a document, usually in the form of a table, used to assist in determining the completeness of a relationship by correlating any two baselined documents using a many-to-many relationship comparison.

Documentation strategy is not essential in establishing requirements traceability.

  • A) True
  • B) False

Answer: B) False

Explanation: Documentation provides an essential foundation for requirements traceability, providing a clear record of requirements and their respective changes over time.

Traceability matrix involves which of the following:

  • A) High-level requirements
  • B) Low-level requirements
  • C) Both A & B
  • D) None of the above

Answer: C) Both A & B

Explanation: Traceability matrix involves both high-level (business) requirements and low-level (detailed) requirements tracking.

True or False: Traceability in business analysis is required only for large projects.

  • True
  • False

Answer: False

Explanation: Regardless of the project size, traceability is critical to ensure that all requirements are met and to manage changes effectively.

Interview Questions

What is the purpose of a requirements traceability strategy?

A requirements traceability strategy helps in tracking the life of a requirement from its inception to its fulfillment. It aids in understanding the origin, the dependencies, and the implementation of the requirements.

Name a couple of techniques for requirements traceability.

Two commonly used techniques for requirements traceability include the Requirements Traceability Matrix (RTM) and the use of traceability software tools.

What is a Requirements Traceability Matrix (RTM)?

RTM is a document that links requirements throughout the validation process, serving as a guide to manage a project’s scope, time, and cost.

How does the level of traceability affect monitoring and validation of requirements?

The level of traceability determines how accurately and effectively the requirements can be monitored and validated. Higher levels of traceability allow for better management and control over changes in requirements.

How do traceability tools assist in requirements traceability?

Traceability tools help in capturing, managing, and linking the requirements, making it easier to track changes and identify dependencies.

What is bidirectional traceability in requirements traceability?

Bidirectional traceability allows tracking of requirements both backwards in terms of origins, sources, and history, and forwards in terms of implementation, functionality, and forward impact.

Why is requirements traceability vital to a project’s success?

Requirements traceability helps in mitigating risks related to changing requirements, it ensures that the project stays within its scope, and it validates that all requirements have been implemented as intended.

In traceability, what does “trace forward” mean?

“Trace forward” refers to tracking the dependency links from source requirements to derived (child) requirements, design, implementation, and testing phases.

In traceability, what does “trace backward” mean?

“Trace backward” refers to tracing from end product or service back to its origin requirement, which helps in impact analysis and avoiding scope creep.

What do vertical and horizontal traceability refer to in requirement traceability?

Vertical traceability refers to tracking requirements from high-level business requirements down to detailed requirements, while horizontal traceability refers to tracking requirements across the same level; typically from requirement to work product.

How can we establish the level of traceability necessary for a project?

The level of traceability for a project can be established by considering several factors such as the project’s complexity, stakeholders’ needs, regulatory compliance requirements, and the impact of potential changes in requirements.

Can changes be made once a traceability matrix is created?

Yes, a traceability matrix is a live document that gets updated as the project progresses. Changes can be made to reflect the project’s current state.

How does traceability support validation of requirements?

Traceability supports validation of requirements by ensuring that all requirements are clearly documented, linked, and tracked from inception to implementation, thus making sure that all requirements are met.

Mention some constraints that might affect requirements traceability.

Some constraints may be limited resources, time, technical constraints, stakeholder availability, and so on.

How does requirements traceability contribute to better risk management?

Requirements traceability provides visibility into dependencies and potential impacts of changes, thus contributing to a more robust risk identification and management process.
