Strengths: Technical and operation expertise.  Culture that teams with clients. Honesty, Integrity, Balance sheet. 
Weaknesses: higher costs and overhead (More service concerns because we compete with smaller companies).  Honesty, we stand by what we do, forever, most competitors don't.
Opportunities: telling our story, we are the good guys!  You want us on your team. Working in more technical facilities.
Threats: Market conditions that force decision makers to take the low price and fight to get their product installed and working properly. Market perceptions of our competitors that provide a lower quality product and/or work in adverserial methods (use vs. them, profit is the only thing that matters)
