LAG and LEAD functions are useful when you want to compare values from different periods. For example, if you want to compare each week’s sales with the previous weeks. | |||

LEAD
Lead is the acceleration of a successor activity. In other words, the second activity can begin (and be conducted in parallel) as the first activity.
Lead is only found activities with finish-to-start relationships: A must finish before B can start.
In order to leverage a lead, which will compress the total combined duration of both activities, the dependency must be discretionary, meaning that there is no physical limitation on completing A before B begins.
