Solution

The correct answer is software validation

Key Points

• Software Validation:
  • This is the process to evaluate the system during or at the end of the development process to determine whether it satisfies the specified requirements. That is, to ensure that 'you built the right thing'. This often involves acceptance testing, where the customer themselves provide the final validation that the system meets their needs and expectations. So it is correct answer of the given question.

Additional Information

• Software Specification:
  • This involves detailed documentation of the requirements and functionalities that the software is supposed to provide. It's essentially the 'what' - explaining what the software is intended to achieve, without detailing how it will do it. It includes elements like functional requirements, performance, interfaces, design constraints, etc.
• Software Design:
  • This the process of envisioning and defining the software solutions to one or more sets of problems. It is the 'how' in the process - covering how the software will achieve the goals set in the software specification. One might think about it as a blueprint that describes the parts and how they should interact with each other. It can have different levels like high-level (or architectural) design and detailed (or low-level) design.
• Software Evaluation:
  • This involves assessment or review of a software product during its development or after its completion to know its usability, quality, performance, etc. It also finds out whether the software meets its intended purpose and satisfies the predefined requirements or not.
