There are two things that you have to do in order to grow your business:

You have to have a really good strategy based on your understanding of the market and competition, future technology, and anything else that is happening in your landscape.
Execution and implementation. I think executing your strategic plan is as important, or even more important, than your strategy itself. Implementation is the process that turns strategies and plans into action in order to accomplish strategic objectives and goals.

Strategy, implementation, and execution are synonymous and we need all three if you are to succeed as an organisation or business entity. One is about the plan and the others are about how to get the plan done, I don’t think you can have one without the others.
