Frequent Verification and Validation

Correct Answer: It allows the team to identify and fix errors early, thus preventing potential major setbacks in the future.

The best answer is 'It allows the team to identify and fix errors early, thus preventing potential major setbacks in the future.' This approach is advantageous because frequent, smaller reviews enable problems to be discovered and addressed sooner, which can save time and resources in the long run; rather than potentially having to resolve larger, more complex issues later which may have compounded over time without earlier detection. The other answers are incorrect. 'It gives the team a chance to take frequent breaks from their work' is not relevant because the aim of reviews is not rest, but progress verification. 'It reduces the amount of work the team has to do' is also incorrect because regular reviews do not lessen the workload but rather help manage it more effectively. Lastly, 'It ensures all team members are constantly busy' is not the purpose of these mini reviews, their main goal is to ensure quality control and efficient progress.

Correct Answer: Show the teams how verification and validation can help them find problems and address them earlier when it is cheaper to fix.

The best strategy to help teams understand the value of frequent verification and validation is to 'Show the teams how verification and validation can help them find problems and address them earlier when it is cheaper to fix.' This reason is based on one of the key concepts of Agile practices, 'early and frequent feedback'. The result of this is early defect detection so that corrections can be made when it is much cheaper to fix. The other options are not plausible because insisting, ignoring concerns or hosting a celebration does not necessarily address the teams' reluctance, provide a useful teaching opportunity, nor represent the Agile values of collaboration and iterative progress.

Correct Answer: Implement verification and validation as mandatory parts of the Definition of Done

The most effective way to ensure frequent verification and validation in a Scrum team is to implement them as mandatory parts of the Definition of Done. When this step is included as a requirement for every task, the team will not skip over these critical stages, thus drastically reducing recode work. Other answers are sub-optimal because performing verification and validation only at the end of a sprint could lead to the accumulation of errors that could take significant time to fix at once. Eliminating these tasks entirely would likely lead to even more issues and recode work. Lastly, allocating specific days for these tasks might disrupt the continuous integration and flow of work if those days clash with other commitments.
