What are the three main types of operations management decisions?

"Production and operations management involve three main types of decisions, typically made at three different stages: 1. Production planning. The first decisions facing operations managers come at the planning stage. At this stage, managers decide where, when, and how production will occur. They determine site locations and obtain the necessary resources. 2. Production control. At this stage, the decision-making process focuses on controlling quality and costs, scheduling, and the actual day-to-day operations of running a factory or service facility. 3. Improving production and operations . The final stage of operations management focuses on developing more efficient methods of producing the firm’s goods or services. All three decisions are ongoing and may occur simultaneously. In the following sections, we will take a closer look at the decisions and considerations firms face in each stage of production and operations management."
