Explain the difference between positive and negative lag time in Project 2010.

What will be an ideal response?


Project 2010 combines the concepts of lag and lead time into one term, lag time. When a project is scheduled from a Start date, positive lag time moves the second task forward in time. (Positive lag time is the traditional definition of lag time in general project management discussions.) Negative lag time moves the second task backward in time so that the tasks overlap. Negative lag time is called lead time in general project management discussions.

There can be multiple choices of shift operators other than those presented in this chapter. Unlike the classical shift, the shift operators W and ( I ? L) do not preserve energy of the graph signal. There also exists a shift operator [21] that preserves energy in the frequency domain. Note that energy of a signal f is || f|| 22
