The seven wastes in the production management process are as follows: The first is the waste of waiting in lean production management. The main causes include uneven workload distribution, improper task scheduling, delays due to waiting for materials, and poor product quality. The second type: waste in handling within lean production management. The main factors behind this are the layout of the workshop, which adopts batch production and features a centralized horizontal arrangement organized around workstations. (That is, mass production in separate process stages), with no concept of streamlined production. Third: The waste of defective products in lean production management is primarily caused by the lack of standard verification in the production processes, or by failure to follow the standard operating procedures even when such verification does take place; it is also resulting from lax and inadequate management. Fourth: Waste in movements within lean production management. The main factors include unplanned production areas, inadequately designed production processes, and non-standardized and inconsistent production movements. Fifth: Waste in processing within lean production management. The main factors include suboptimal sequencing of operations during the manufacturing process, as well as failures to identify those steps that can be omitted, replaced, reorganized, or combined. Sixth: Waste of inventory in lean production management. The main factor is the creation of large amounts of inventory in certain areas, as managers place orders for bulk production to facilitate their own work or to achieve quantitative control over production in those areas, without taking into account the requirements of the overall production plan. The negative effects of inventory in lean production management include: (1) the creation of wastes such as unnecessary handling, stacking, placement, protection measures, and searching. (2): Makes first-in-first-out processing difficult. (3): Lost interest and administrative fees. (4): The value of the item decreases, turning it into obsolete goods. (5): It occupies factory space, resulting in wasted investment in the construction of additional workshops and warehouses. (6): The lack of managerial pressure hinders improvement. (7): Misjudgment of equipment capacity and personnel requirements. Seventh: The waste of producing too much (too early) in lean production management. The main factors behind this are managers’ belief that producing too much and too early can improve efficiency, reduce losses in production capacity, and balance workshop productivity. The consequences of causing excessive (premature) damage include: (1) Expenditure on costs (materials and labor) is incurred ahead of time, preventing the generation of profits. (2): Hide the \"waste of waiting\" so that managers ignore the occurrence and existence of waiting. (3): Work-in-progress accumulates naturally, which not only prolongs the processing time (in an invisible manner) but also increases the space required at the work site; as a result, the distance between machines grows, gradually eroding profits. (4): It causes waste from handling and stacking, making FIFO operations difficult.
