Which of the following may not help in improving predictability?

Estimating in hours instead of points may not enhance predictability because it introduces greater variability and uncertainty in how time is perceived compared to story points, which allow teams to assess both effort and complexity. Story points help account for the differences in understanding and capabilities among team members, which contributes to more stable velocity over time. This stability aids in making forecasts about future work more reliable.

In contrast, reducing technical debt, shortening feedback cycles, and respecting work-in-progress (WIP) limits all foster predictability by creating a clearer and more efficient workflow, facilitating quicker adaptations to changes, and ensuring that teams are focused on a manageable amount of work at any given time. These practices enhance team velocity and project flow, thereby supporting more accurate project predictions.
