Answer: b) No
Explanation:
If you double the capacity of the bottleneck operation i.e the operation that has a limited capacity that is causing the entire project to slow down, it could work for removing the bottleneck from that particular operation. The problem however, is that this bottleneck might then be passed into another operation which will then slow down the entire process again.
Think of this this way, imagine there is constant traffic on one road with a double lane in a city and the city decides to up it to a four lane drive. The traffic subsides in that area but still continues on the road lane after the upgraded road which is a 2 lane as well.
The problem may have been fixed in one area but might just come up in another one.
