Is Lean only for manufacturing companies?

No. Although lean started with Toyota and automotive manufacturing the principles are applicable to all organisations. Service sector organisations are constantly under pressure to deliver excellent customer service, faster response times and more value for their customers. Lean can help to optimise all service delivery processes by targeting wastes and either removing them completely or move to a more effective state as part of a journey of continuous improvement. Large organisation like Tesco have embraced lean principles for many years in raising standards of customer service and reducing costs in their supply chain.
