# Resource forecasting and optimization

The ability to evaluate future workloads and utilization in order to optimize task assignment across the organization requires that the system forecast expected work in the future. Arrow calculates this future work leveraging project tasks that the resource been allocated to with the remaining work over the duration of the task.

That is, a resource's commitment on a day is calculated as **(Task Hours Remaining * Task Allocation) / Task Duration**.

For each task in the system Arrow creates a forecasted, or expected, Arrow calculates the hypothetical time entries by resource on an hourly basis. For example. If a resource is assigned to a 20 hour task that is expect to last 5 days. The system will record 5 time entries (one for each day) of 4 hours each. 

The forecast job can be setup hourly, daily or weekly. We recommend running the job hourly to provide the most real-time updates for your users.
