A production cell is a group of machines or workstations that are arranged in a layout that facilitates the flow of materials and work-in-progress in a manufacturing system. A production cell is usually designed to produce a family of products or services that have similar characteristics or requirements. A production cell is often based on the principles of lean manufacturing and group technology, which aim to eliminate waste and improve quality. When designing a production cell, the most important consideration is the flow of materials into the cell and sequencing of operations to minimize total cycle time. The flow of materials into the cell refers to the movement and direction of the raw materials, components, or modules that enter the cell for processing. The sequencing of operations refers to the order and arrangement of the machines or workstations that perform the processing steps within the cell. Minimizing total cycle time refers to reducing the time it takes to complete a product or service from start to finish. By considering these factors, a production cell can achieve high efficiency, flexibility, and productivity.

The other options are not the most important considerations when designing a production cell. The unit per hour requirement for the production cell to meet the sales forecast is not the most important consideration, as it is a result of the demand planning and capacity planning functions, which are separate from the production cell design. The unit per hour requirement indicates how many units of a product or service the production cell needs to produce in an hour to meet the expected customer demand. The output rate for the first operation and move time after the last workstation are not the most important considerations, as they are only parts of the total cycle time calculation, which also includes the processing time and waiting time for each operation. The output rate for the first operation is the number of units that the first machine or workstation in the cell can produce in an hour. The move time after the last workstation is the time it takes to transport the finished product or service from the last machine or workstation in the cell to the next stage or destination. The take time requirement for each operator to meet the monthly production goals of the plant is not the most important consideration, as it is a measure of labor productivity, which is affected by factors such as skill, training, motivation, and supervision. The take time requirement for each operator is the amount of time that an operator needs to complete one unit of a product or service. References: CPIM Exam Content Manual Version 7.0, Domain 6: Plan, Manage, and Execute Detailed Schedules, Section 6.2: Detailed Scheduling Methods, p. 38; Cellular manufacturing; Production Cell.
