02.  Keys to business development
.New location,When a proven business hits a growth roadblock, owners should consider opening a second location. Operating from two locations will offer customers greater convenience and give business owners an opportunity to expand their customer base. Even smaller, satellite locations can be beneficial in developing a profitable business.
.Stay ahead of competition,One reason companies stop growing is failure to stay competitive. Offering the latest technologies and improved products will give a small business the competitive level. Develop your company by expanding services and catering to market trends. This may be accomplished by staying on top of breaking industry news and keeping an eye on local competitors.
.Multiply income,Beyond expansion, multiplying business income is achievable through enhancing the current product line with accessories and specialized services. Take on the role of "expert" in your business field by offering classes, workshops and creditable internships. Showcase in-house talent by marketing leaders for speaking engagements at seminars and conferences.
.Upgrade technology,Upgrade current business technologies by buying new equipment for managing inventory or for packaging products. If your company has a website, consider adding new features. Grab new domain names and re-route traffic to your primary web address. Buy new gear such as fast phones, laptops or office equipment. A good development strategy should include motivating employees with the right tools for business.
.Increase the market,It's tempting to stick with reliable products, but sometimes you need to expand the line to garner new customers. Review your current product line and then compare it to similar companies. Follow up the review by adding missing products or services. You could also gather customer feedback through surveys or focus groups. Ask the consumer directly what he'd like to see. 
.Build alliances,Smart alliances can make businesses stronger. Established businesses could find a greater audience by partnering with companies that offer complementary services. Alliance relationships will take businesses to new marketplaces and open the door to possible new products. An alliance of several businesses can corner a local market and
offer customers a one-stop solution center. Alliance building is profitable, but should be a thoughtful, careful process.
