Bottlenecks are fairly common, and most managers understand what they are. Bottleneck (Constraint) Bottlenecks determine the throughput of a supply chain. Recognizing this fact and making improvements will increase cash flow. A bottleneck (or constraint) in a supply chain means the resource that requires the longest time in operations of the supply chain for certain demand. (Source)
Understanding that bottlenecks affect the end result of your throughput is essential. When you map a process, the path that takes the longest time is called the "Critical Path". You won't find ALL of the bottlenecks along this path, but the critical path most likely has dependent tasks that are delayed due to the constraint of another task.
We pair the Critical Path Method (CPM) from Project Management Professional train of thought with our LEAN Six Sigma Calculations to eliminate waste and find out the exact causal factor resulting in a bottleneck. Finding the exact cause is vital to saving money on the solution and we happen to be experts.
