This is nonsense to get you to work more for the same pay.

Its good to do this to get an idea of what it means to work on a higher level but it WILL NOT get you promoted.

Promotion is about leverage. What can you supply that no one else can and thats crucial for your bosses-boss's success?

Stop thinking execution - its exactly the opposite of that.

Can you recruit people from other organizations, can you create a new product, work with every part fo the comapny, evangelize the company externally, attract capital ...
