Currently in WWE when it comes to power and decision-making within the company, there are several people involved in the process, however the only real key decision makers are Vince McMahon and Triple H.
Regarding a lot of changes that takes place during WWE RAW, which is the company’s top priority presently, they don’t even begin talking about what they are going to do on SmackDown until late Monday afternoon.
Apparently around 6pm on Monday’s, Vince McMahon will ask the writing team to give him a main event for SmackDown so that it can be promoted during RAW. At that point, writers begin scrambling for ideas for a big match. Apparently that is the reason why WWE SmackDown and WWE Main Event matches announced on RAW frequently change.
