Manufacturing Cell
A production unit that groups dissimilar machines and processes together to manufacture a family of similar parts or products. Manufacturing cells support flexible production, reduce setup times, and improve quality by enabling quick feedback between operations.

Work Cell
A dedicated arrangement of equipment, tools, and workstations grouped together to perform a specific set of manufacturing operations efficiently. Work cells are designed to minimize material handling, reduce cycle time, and enable operators to complete multiple process steps within a compact area.
Lean Manufacturing
A systematic approach to manufacturing derived from the Toyota Production System that focuses on eliminating waste while delivering value to customers. Lean identifies seven types of waste (overproduction, waiting, transport, overprocessing, inventory, motion, and defects) and uses tools like value stream mapping, 5S, and kanban to continuously improve processes.
Changeover Time
The time required to switch a machine or production line from making one product to another, including setup, adjustment, and first-article inspection. Reducing changeover time through techniques like SMED (Single-Minute Exchange of Dies) enables more flexible production and smaller batch sizes.
Job Shop
A manufacturing environment that produces custom or small-batch products with varied routings through different workstations based on specific job requirements. Job shops offer high flexibility to handle diverse customer orders but typically have longer lead times and higher per-unit costs than high-volume production.
