Kelsey Manufacturing is facing declining sales as its product lines have become stagnant and mature. The company still operates like a family business rather than a corporation, and lacks an understanding of its distribution channel problems. It needs to consult channel partners to refine its product lines, select exclusive distributors, promote directly to end customers, rationalize margins, and invest in technology to modernize. Pruning unprofitable products, focusing distribution, and addressing partner concerns could help Kelsey reverse its sales trend.
