Answer:
Production.
Step-by-step explanation:
A budget is a financial plan used for the estimation of revenue and expenditures of an individual, organization or government for a specified period of time, often one year.
Basically, budgets are usually compiled, analyzed and re-evaluated on periodic basis.
The key principle of supply chain management can be best summed up as collaboration between multiple firms. Thus, these multiple firms include a company that is saddled with the responsibility of manufacturing, a wholesaler, and a retailer who typically sells the products to the customers or consumers.
A retailer can be defined as an individual or company that buys finished goods directly from a wholesaler and sells directly to the end users (consumers).
In this context, a retailer would prepare an administrative, sales and cash budget but certainly wouldn't prepare a production budget because retailers aren't saddled with the responsibility of producing goods.
Simply stated, a production budget would be prepared by a manufacturer or producer.
