CCR Vs Bottleneck

Notice that, a bottleneck refers to the limiting step in a process. In contrast, a CCR refers to any resource whose capacity is less than the demand placed on it.

So, there are many possibilities. You can have

• A process which has one bottleneck while every step is a CCR.
• A process which has one bottleneck but no CCR (in this case, you would not want to run at capacity)
• A process which has multiple bottlenecks and multiple CCRs.
