Explanation:
Direct observation of results is better than estimations and qualitative information gained from interviews or status reports. Project managers and involved staff tend to underestimate the time needed for completion and the necessary time buffers for dependencies between tasks, while overestimating the completion percentage for tasks underway (80:20 rule). The calculation based on remaining budget does not take into account the speed at which the project has been progressing.
