Are you transforming to lean fast enough?

Yet, the reality is that manufacturing operations are often besieged with constantly changing priorities, demand for product that doesn't match forecast, suppliers not delivering on-time, product specification problems, capacity imbalances, material flow interruptions, long cycle times, and ineffective ERP systems that are of little help in dealing with these day-to-day issues. Many lean manufacturing efforts have failed to consider the need for comprehensive internal and external business process changes, including policies, attitudes, performance measurements, peripheral business practices, organizational behavior, and supporting information technology.
