Compared to developing a system in-house, acquiring a software package means that the need for testing by end users is unchanged. This is because end users are still the ultimate customers and beneficiaries of the system, and they need to ensure that the software package meets their requirements, expectations, and satisfaction. End user testing, also known as user acceptance testing (UAT) or beta testing, is the final stage of testing performed by the user or client to determine whether the software can be accepted or not1. Enduser testing is important for both in-house developed and acquired software packages, as it helps to verify the functionality, usability, performance, and reliability of the system2. End user testing also helps to identify and resolve any defects, errors, or issues that may not have been detected by the developers or vendors3.

Therefore, option B is the correct answer.

Option A is not correct because end user testing is not eliminated by acquiring a software package. Even though the software package may have been tested by the vendor or supplier, it may still have bugs, compatibility issues, or configuration problems that need to be fixed before deployment4. Option C is not correct because end user testing is not increased by acquiring a software package. The scope and extent of end user testing depend on various factors, such as the complexity, criticality, and customization of the system, and not on whether it is developed in-house or acquired. Option D is not correct because end user testing is not reduced by acquiring a software package. The software package may still require modifications or integrations to suit the specific needs and environment of the organization, and these changes need to be tested by the end users.
