During the planning phase of a project estimations play a critical role. For medical device projects the cost estimation is not always straightforward as discussed in the lectures. Another estimation that can be misleading is the task duration estimation provided by individuals. Often times while working in industry you notice that team members underestimate the task duration completion. This can occur because of lack of expertise/knowledge in a new area of research or as mentioned in the lecture issues can come up such as being sick. There have been instances at work where we receive an estimate for a week from certain facilities on international projects and the task is not completed within the time period referenced. As a project manager these problems may arise because of differences in work culture/certain facilities being more busy on a another project and not being able to deliver on time. What are some methods that a project manager can develop in order to properly account for employees underestimating task duration? Do you have specific examples from your experience where you ran into these problems, if so were you able to find solutions?
