Quoting from [zongren]:
Our product is very competitively priced with good quality and our company is the market leader in our industry. What do you suggest we do to maintain our market dominance?
zongren - Defending your market dominance should be top priority for your company. In one word "innovation" should be your first response. Your company as a market leader should continue to develop new products, provide superior customer service, effective distribution channel and find ways to cut cost. Those will certainlly help your market dominance last.
