Introduction “A chain is only as strong as its weakest link” (Goldratt, 1984). Goldratt’s theory means organizations and processes are vulnerable because the weakest part or person can damage, break, or constrain them while affecting the outcome. In operations management, the solution is to pull materials through the system rather than push them into the system. By using the drum-buffer-rope methodology, components in a system can be identified helping to identify constraints and eventually break the constraint or find a solution. Bottlenecks: Goldratt’s Theory of Constraints helps identify bottlenecks in the process of fixing a flashlight and how to fix or break the constraints.
Drum-Buffer-Rope
Named for its three components, drum-buffer-rope is a manufacturing mythology execution. The physical constraint of the plant is the drum. The drum could be a machine or work center and limits the whole system to produce more. The drums are protected by buffers which always keep work flowing to it. Buffers are measured in units of time rather than the quantity produced. Buffers are usually placed at the constraint, shipping, and synchronization points. The work release mechanism for the plant is represented by rope. Orders are released before they are due at a certain buffer time. If the buffer is one week, the order is released one week before it is due at the constraint. The drum-buffer-rope mythology will be very useful to solve the problems in process of manufacturing and selling a flashlight.
Constraints and Solutions According to "Theory of Constraints" (2013), “TOC is systemic and strives to identify constraints to system success and to effect the changes necessary to remove them” (Theory of Constraints). The drum would be the equipment used to manufacture the flashlights or even the employees that are putting them together. Continuously providing work to the system,
