According to the web search results, the production plan is a long-term plan that establishes the

quantity and timing of the end products to be produced by the company1. The production plan is

based on the

forecasted demand,

the

available

capacity,

and the

company’s strategic

objectives2. The production plan is also used to authorize and guide the master schedule, which is a

more detailed and short-term plan that specifies the quantity and timing of each end product to be

produced in each time period3. The master schedule is derived from the production plan, and it must

not exceed the production plan’s limits. Therefore, the major contribution of the production plan is

to provide authorization for the master schedule.

The other options are not correct, because they are either irrelevant or inaccurate. The production

plan does not establish demand by end item, but rather responds to the forecasted demand by end

item. The production plan does not identify key resources to support the master schedule, but rather

determines the overall resource requirements to meet the production targets. The production plan

does not establish the weekly build schedule, but rather provides the basis for the weekly build

schedule, which is a more detailed breakdown of the master schedule that specifies how many units

of each end product will be built in each week.
