One thing that makes aggregate planning in services easier than aggregate planning in manufacturing is: multiple choice a) inventory is cheaper to hold. b) labor availability is more predictable. c) inventory is less perishable. d) labor is more flexible. e) demand is less variable.

The correct answer is d) Labor is more flexible.

Explanation:

Aggregate planning is used to increase production in a company, choosing a method to meet demand and the optimal time for product development. And there is the planning added to the service area and the planning added to the manufacturing.

When talking about the planning aggregate to the service, reference is made to companies that do not produce but offer services, so these companies do not manage an inventory, and these require more personnel in charge of providing these services, this makes the job more flexible.

On the other hand, the planning aggregate to the manufacturing requires that a product be produced, and these produce an inventory, through the catalogs they can know the demand of the customers and the planning is for the materials and products that will be manufactured, this makes it a less flexible job.

Therefore, it can be concluded that due to the difference in work in the service and billing companies, it can be found that the service company´s work is more flexible because they do not have an inventory to follow.
