Today's e-commerce spurs demand for reduced response times in fulfillment centers; generally has fewer products per order; and is constantly changing -- increasing system complexity and the need for flexibility in automation. Today's warehouses and distribution centers are far more complex than they were 10 years ago and employee turnover remains high; with complexity comes higher wages yet labor is increasingly hard to find -- all adding to the equation. Businesses are making investments in a variety of technologies to improve their inventory control, order processing methods, labor situation and to enhance their pick and pack operations to be faster, less rigid, requiring less physical exertion, and achieve more accurate results. "These factors are contributing to the need to convert warehouses and distribution centers into assets for competitive differentiation. Mobility will be front and center in this shift, says VDC Research in their recent'Taking Advantage of Apps and App Modernization in Warehousing' report.
