Lean is about the elimination of all waste in order to develop an operation that is faster, more dependable, that produces higher quality products and services and above all operates at lower costs. Lean is a strategy for change. It is about all staff involved, contributing to working towards creating the value that the customer needs. Lean requires a commitment to continuous improvement in an organization. It is focused on optimizing a process, to ensure maximum responsiveness to customer needs.
What are the benefits of lean? Typical results such as the following are often quoted:
• Reduction in inventory > 80%
• Defect reduction > 30%
• On time delivery to customers increased to the order of 99%
• Process lead time reduction of 70%
• Return on asset improvements of 100%
Just In Time Processing.
JIT aims to align demand with supply, from the end use customer back to sub-supplier processes. The better demand and supply are aligned, the greater the efficiencies. In tandem with balanced demand and supply and the needs for right first time quality combined with the elimination of waste.
Just In Time can be seen as a set of techniques, for managing operations which focuses on aspects such as the following:
• Basic work practices
• Design for manufacture
• Set-up reduction
• Kanban control
• Flow layout
• JIT supply
• Increasing capacity through minimal investment
• Pull scheduling
• Level scheduling
• Product orientated layout
• OEE (Overall equipment effectiveness)
• TPM (Total preventative maintenance).
In many organizations, with a continuous improvement objective, Lean Manufacturing Process Improvement & Just In Time, go hand in hand.
