Estimating schedule activity costs involves developing an(4)of the cost of the resources needed to complete each schedule activity. Cost estimating includes identifying and considering various costing alternatives. For example, in mostapplication areas, additional work during a design phase is widely held to have the potential for reducing the cost of the execution phase and product operations. The cost estimating process considers whether the expected savings can offset the cost of the additional design work. Cost estmates are generally expressed in units of(5)to facilitate comparisions both within and across projects. The(6)describes important information about project requirement that is considered during cost estimating.
Estimating activity durations uses information on activity scope of（），required resource types, estimated resource quantities, and resource calendars.
On some projects, especially ones of smaller scope, activity sequencing, activity resource estimating, activity duration estimating, and （） are so tightly linked that they are viewed as a single process that can be performed by a person over a relatively short period of time.
Involvement in community activities ______ an integral and inescapable part of senior managers' jobs.
The process of（）schedule activity durations uses information on schedule activityscope of work, required resource types, estimated resource quantities, and resource calendarswith resource availabilities.
Project schedule management is made up of six management processes including: activity definition, activity sequencing（）and schedule control by order.
The process of（）schedule activity durations uses information on schedule activity scope of work, required resource types, estimated resource quantities, and resource calendars with resource availabilities.
