Bottlenecks in a Process PAGE 1
Bottlenecks in a ProcessBy definition, a bottleneck is any resource whose capacity is insufficient to satisfy the demand upon it. For example, in a computer network a server could become a bottleneck if it can't send the required data to all computers that request it. Bottlenecks can be not just machines or specialized equipment; skilled workers also can be bottlenecks in a process (Schwab J. & Gerard F, 2006.)The effect bottlenecks have in production lines is that they limit throughput. In addition, if a process did not have a bottleneck, which would be an indication that there is excess capacity. A resource that is not a bottleneck is referred to as a no bottleneck.Goldratt's Theory of Constraints (TOC)According to Goldratts, time lost at a bottleneck is time lost for the entire system. (citation) Similarly, time saved at a bottleneck is time save for the entire system. Bottlenecks act as constraints, and determine the thoroughput of the system. Priorities can only be set by examining the system's constraints. To improve performance, constraints can be identified, and more capacity added to them (Schwab J. & Gerard F, 2006.)Process analysisThe process I am analyzing is driving to the Unemployment office. This process is depicted in Figure #1. The metric that measures the performance of this process is the time that it takes to drive to the Unemployment office.Figure 1. Flowchart of current process driving to the Unemployment office.I have collected data for this process for three weeks. Table 1 provides a summary for the same.
