What is Verification and Why is it Important?

Verification is the process of evaluating or confirming, through objective means, that a system, product, or service meets certain requirements or standards. It involves checking and validating the correctness of the system, product, or service against its specifications, design, or other relevant criteria. Verification can be performed at various stages of development, production, and deployment, and it is an important aspect of quality control and risk management in many industries.

Verification can be done through various methods such as:

1. Inspection: Visual examination of the system, product, or service to ensure that it meets the specified requirements.
2. Testing: Execution of specific tests to evaluate the functionality, performance, and other aspects of the system, product, or service.
3. Review: Examination of documents, plans, and other records to ensure that they are complete, accurate, and meet the required standards.
4. Audit: Systematic examination of records, processes, and systems to ensure compliance with regulations, standards, and other requirements.
5. Validation: Confirmation that the system, product,or service meets its intended purpose and user needs.

The goal of verification is to ensure that the system, product, or service being developed or deployed meets the specified requirements and is fit for its intended purpose. It helps to identify defects, errors, and other issues early in the development process, which can save time and resources by avoiding costly rework or recalls later on.
