Mike wants the testing team to evaluate completed features during development. Which type of dependency should he use?

The appropriate type of dependency for Mike's scenario is the finish-to-finish dependency. This dependency indicates that one task cannot be considered complete until another task is finished. In this context, since Mike wants the testing team to evaluate the completed features during the development process, it is essential that both the development work and the testing process occur in tandem.

The finish-to-finish dependency allows for a collaborative workflow where the testing team can assess features as they are developed rather than waiting for the entire development phase to conclude. This approach promotes early detection of issues and ensures that feedback can be integrated into the development process, leading to improved quality and efficiency.

In contrast, other types of dependencies such as start-to-start, finish-to-start, or start-to-finish do not align with the need for concurrent evaluation of development features by the testing team. For example, a finish-to-start dependency would imply that the testing cannot begin until the development is fully completed, which contradicts the objective of ongoing evaluation during development.
