What does the Opportunities mean in a SWOT analysis and what is the best way to find them for a healthcare clinic?

Opportunities within a SWOT analysis are opportunities which are determined after looking at your strengths and weaknesses. Obviously opportunities will line up to strengths vs weaknesses. Threats can be risks related to these opportunities or current operations you have now.

To determine opportunities for a healthcare clinic you would need to break down your operation into it's key components, e.g. patient care services offered today, patient care services which are not offered today but may become an increasing demand in the future, cost management to provide services today, cost management to provide future services, etc. Basically mapping your current "value chain" from your patient backwards to whatever it takes you to provide care for those patients.

As you do this you should be able to look more strategically at your current operations and what new demands you make face in the future, or what demands are out there today which are not being serviced or not being serviced well by someone today. These should be the basis of your "opportunities". Just make sure you look at your operation end to end so you don't miss the impacts of the choices you make on the front end.
