Article One
These three systems are productions and inventory management strategies that aim to minimize waste and maximize efficiency ensuring materials and products are received or manufactured only when they are needed. Just-In-Time (JIT) is a pull-based system that produces items only as needed, reducing waste and inventory. Material Requirements Planning (MRP) is a push-based planning system that schedules production based on forecasted demand. Also, Synchronized manufacturing is a system that aligns the flow of materials and production rate across the supply chain, often using Theory of Constraints (Aggarwal, 2025). When looking at raw material inventory, JIT is very low and delivered as needed. MRP is high due to the forecast-based planning and synchronized manufacturing is moderate since it's based on constraint-driven flow. For WIP inventories, JIT is minimal, MRP can be high due to batch processing, and synchronized manufacturing buffer only at constraints (Aggarwal, 2025). JIT's production lead time is shortened by eliminating delays. MRP's is often longer due to batch sizes and safety stocks and synchronized manufacturing is focused on reducing overall lead time through constraint management. Also, JIT's cycle lead time is short, MRP's is long, and synchronized manufacturing is balanced, meaning it can be short when there are no constraints (Aggarwal, 2025). JIT might be used in the automotive industry, this is because the industry has a stable demand and reliable suppliers. MRP will be used in industries that require complex assemblies since there are long lead times and predictable demand. Lastly, synchronized manufacturing may be used in custom products where there are environments with clear constraints and variability.

JIT (Just-in-Time) foucuses on minimizing inventory levels by delivering parts and materials exactly when they are needed in the production process. MRP (Material Requirements Planning) is a system that calculates the materials needed for production based on demand forecasts and lead times. Synchronized manufacturing, on the other hand, involves coordinating all aspects of production to ensure smooth flow and minimize waste, often using tools like Lean principles and Six Sigma techniques. Genuinely synchronized manufacturing places more focus on overall system performance than on localized metrics like labor or machine utilization (Jacobs & Chase, 2024). MRP is typically used in industries with complex production processes and high inventory levels, while synchronized manufacturing is more commonly found in lean manufacturing environments with a focus on continuous improvement. Both systems aim to optimize production efficiency and minimize costs by closely monitoring and controlling all aspects of the production process. As for JIT, it is a production strategy that aims to reduce waste by only producing goods as they are needed in the production process, JIT is often used in industries with low inventory levels and a focus on reducing lead times and improving overall quality. This system requires close coordination between suppliers and manufacturers to ensure materials are delivered just in time for production.

Article Three
I work for a small restaurant chain which I have held many different positions for. During my time here, I have witnessed several factors in the system of the restaurant that can be improved on to better serve customers and improve their experiences. The bottleneck that I recognized in the restaurants is the ordering process and the communication of orders between waitresses and the kitchen. The kitchen operates completely off of pencil and paper, a very outdated method which was slow and often led to confusion within the kitchen. However, this is how the restaurant has ran for decades so it has proven to work well enough. The newest location for the business opened and due to the layout of the kitchen and restaurant as a whole, we quickly realized that the ordering process needed to be updated. Walking paper back and forth for orders was not going to work in this specific layout. The location was upgraded to a new point of sale system that allows the waitresses and the kitchen to communicate orders instantly through computers and monitors. POS systems are feature-rich, offering functionalities beyond order placement and transaction processing. They can manage inventory, track customer data, payroll, and manage delivery, all through a unified ecosystem that flows smoothly (Hungerrush, 2024). This solution has allowed the system of the new location to run much more efficiently, resulting in quicker service, quicker transactions, and more accurate order deliveries. I believe that eventually the success of this location will be enough motivation for the other locations to adopt the same system.
