In which change implementation method may not all users value early phases and risk losing interest in the system?

The chosen method indicates that during a phased implementation, changes are introduced gradually over time rather than being rolled out all at once. As users may only experience parts of the complete system in its early phases, they might not fully appreciate the potential benefits of the entire solution right away. This limited exposure can lead to frustration or disengagement as users may struggle to see how the piece they are working with fits into the larger picture.

In contrast, other methods like direct changeover or parallel running ensure that users see the full functionality either immediately or alongside the existing system, which can help maintain their interest and investment in the overall project. Therefore, phased implementation can indeed lead to diminished enthusiasm among users who may not perceive the value of what they are initially tasked with navigating.
