What process confirms that specified requirements have been fulfilled through thorough examination?

The process that confirms that specified requirements have been fulfilled through thorough examination is verification. Verification refers to the activities that ensure the software product meets the specified requirements. It involves reviewing and evaluating the work products to ensure they align with the expectations set forth in the requirements documentation. This can include inspections, reviews, and static testing methods that focus on ensuring correct implementation without executing the code.

In the context of software development, verification makes sure that the outputs of each phase of the development process are correct according to the inputs of that phase. This means confirming that the product is being built according to the requirements before it undergoes actual execution, which is where validation typically comes into play. Validation checks whether the product, when tested in its operational environment, meets the needs of the end-users.

Testing, while related, focuses specifically on executing the code to find defects and does not solely involve the examination of requirements fulfillment. A review can be a part of verification but is not the complete process by itself that ensures all requirements are met; verification encompasses a broader range of activities.

The essence of verification is to establish confidence in the quality of the product by ensuring it adheres to the required specifications at various stages of development. Thus, verification is the process that accurately aligns with
