It means that big companies don't get to be big companies by doing dumb things (mostly), so do the things that big companies do:
-Develop good business structure.
-Focus on good governance, compliance, and oversight.
-Execute good strategic planning and market surveillance.
-Focus on employee development, training, and support.
-Focus on elements that will lead to a positive work environment.
-Provide outstanding Customer Service.
Small companies are able to:
-Communicate through the organization quickly.
-Make speedy, timely decisions.
-Execute plans without a lot of red tape.
-Adjust to adversity quickly and keep moving forward.
-Focus on individual employee development.
If you think big, like a big company, you will be moving in the right direction for your organization in the long term.
And, if you act small, you will be able to nimbly plan, act, and adjust to ever changing business conditions.
This applies to any organization size that you are in:
Big companies continue to think big, but act small, and
Small companies think big, and continue to act small.
