W.H. Plastics faces challenges including a highly competitive industry, reliance on one major customer for 74% of sales, and uncertainty from foreign exchange rates. The company is considering strategies like attending global trade shows to build relationships and gain industry insights, developing an online presence to target likely customers, and sourcing low value-added parts from China to control costs. A staged 24 month plan is outlined to implement these strategies and monitor their impact on reaching the company's profit margin target.
