Regulation play for a regular season game is 60 minutes long. Three 20 minute periods. 5 minutes for 1 overtime period if necessary(tie game). Playoff hockey is the same except that overtime periods are 20 minutes in length and more periods added until game is decided.(sudden death).
DEFINITION of 'Activity Cost Driver'. A factor that influences or contributes to the expense of certain business operations. In activity based costing (ABC), an activity cost driver is something that drives the cost of a particular activity. A factory, for example, may have running machinery as an activity. The activity cost driver associated with running the machinery could be machine operating hours, which would drive the costs of labor, maintenance and power consumption of running the machinery activity.
This new estimated activity time is known as the crash time, and the cost to achieve the crash time is referred to as the crash cost. Activity 1-2 can be crashed a total of 5 weeks (normal time - crash time = 12-7 = 5 weeks) at a total crash cost of $2,000 (crash cost - normal cost = $5,000-3,000 = $2,000). Dividing the total crash cost by the total allowable crash time yields the crash cost per week: If we assume that the relationship between crash cost and crash time is linear, then activity 1-2 can be crashed by any amount of time (not exceeding the maximum allowable crash time) at a rate of $400 per week.
