Please provide feedback and reaction to discussion below. A project is a “temporary activity launched for a specific purpose, to carry out a particular objective” (Wallace, 2020, p. 354). Projects are generally special and specific to a certain task. They also can contain many complicated or long-term steps that are needed to complete the project. In a project, steps and tasks are not always straight to the point. Because projects are unique, there are constraints to be followed. These constraints are forces that consists of time consumption, costs and budgets, and scope (Wallace, 2020). These forces work hand in hand and affect each other differently. A process is different from a project and generally less complicated. While projects contain complicated and elongated steps, processes are usually shorter and straight to the point. A process “is a series of events designed to deliver a product or service that is repeated over and over” (Wallace, 2020, p. 354). In order to keep the…
Specifying optimistic, pessimistic, and most likely or mode times are sufficient to generate the beta distribution describing completion times. The applet opens with values Optimistic = 2 weeks, Pessimistic = 11 weeks, and Mode = 4 weeks. Drag the mode line inside the distribution to see how the shape changes as expectations about the most likely outcome change. Drag between 0 and the current Optimistic value to change the Optimistic value. Drag, in either direction, beyond the upper end to change the pessimistic value.
