Project Description Notes: First, before any tasks are entered, click on the Project tab, Change working time, Work weeks, Details. Make all 7 days of the week working days from 8am to 12pm and 1pm to 5pm. Predecessors are entered as numbers. Enter task names (a, b, c, etc.), durations, and predecessors as numbers. Under Tasks, add columns of custom information, to add ES, EF, LS, LF, and Total Slack (MSP will calculate these automatically) Project Table 5-3 MSP Intro Example 1 of a a a b,c d d,e f g,h
