Exercise 1: Dependency Matrix

Think about the activities you must do to buy a ticket to travel to Hawaii, then fill in the dependency matrix

EStiMatingtaSk Duration: Task duration can be hours, days, or weeksdepending on the project. Because the following example uses days, the units of measurement are called person-days. A person-day represents the work that one person can complete in one day. This approach, however, can present some problems. For example, if it will take one person 20 days to perform a particular task, it might not be true that two people could complete the same task in 10 days or that 10 people could perform the task in two days. Some tasks can be divided evenly so it is possible to use different combinations of time and peopleup to a pointbut not all. In most systems analysis tasks, time and people are not interchangeable. If one analyst needs two hours to interview a user, two analysts also will need two hours to do the same interview. Project managers often use a weighted formula for estimat- ing the duration of each task. The project manager first makes three time estimates for each task: an optimistic, or best-case estimate (B), a probable-case estimate (P), and a pessimistic, or worst-case estimate (W). The manager then assigns a weight, which is an importance value, to each estimate. The weight can vary, but a common approach is to use a ratio of B = 1, P = 4, and W = 1. The expected task duration is calculated as follows: (B + 4P + W) 6
