"Implementing and executing strategy involves a company's whole management team and all employees just as every parts of a watch plays a role in making a watch function properly, it takes all pieces of an organization working cohesively for a strategy to be well executed"

"while top level managers must lead the process and orchestrate major initiatives, good execution requires that middle and lower level managers see that things are in sync and on track in their areas of responsibility and employees perform their roles competently on a daily basis"

Justify two statements with suitable example. Short example would be better.
