Which practice is primarily focused on reducing waste in manufacturing?

The practice that is primarily focused on reducing waste in manufacturing is Just In Time (JIT). JIT is an inventory strategy that aligns raw-material orders from suppliers directly with production schedules. This approach minimizes the amount of inventory held at any given time, thereby reducing waste associated with excess inventory, obsolescence, and storage costs.

JIT operates on the principle of producing or acquiring goods only as they are needed in the production process, which leads to a more efficient use of resources. By ensuring that materials arrive precisely when needed, companies can reduce the likelihood of surplus items that would otherwise contribute to waste. This method not only improves efficiency but also enhances flexibility in responding to customer demands, as manufacturers can quickly adjust their production based on real-time needs.

The emphasis on waste reduction, efficiency, and lean manufacturing practices makes Just In Time a cornerstone of modern manufacturing and a highly effective approach to minimizing waste.
