What is Lean.

          ‘Lean’ means thin and well-trimmed. Working with lean means working systematically
to eliminate all non-value-adding processes in order to achieve your goals with the least possible effort. Unnecessary work, or waste, is used in this connection as an umbrella term for anything that does not create customer value. In the search for waste, you need to look for anything that ‘can’t be
invoiced’. Waste is what the customer won’t pay for. Eliminating waste is also a good idea from the point of view of the employee: No one likes to produce something that isn’t used.

"Lean thinking is a business methodology that aims to provide a new way to think about how to organize human activities or a process to deliver more benefits to the company/organization and value to individuals while eliminating waste.'

When you are applying LEAN,

there  are three fundamentals things, which are as follows:

• Do the right thing
• Do it right
• Get better

• Do the right thing
•  Doing the right thing is the easiest way to avoid waste.this means using your technical competencies to meet the customer’s needs and avoiding over or under developing the solution. In practice, it is about properly communicating expectations to the recipients of the work. This includes both internal and external customers. Because needs and expectations are not static, it can be useful to maintain a close dialog with the customers throughout the lean process.
•  Do it right
• Doing it right means optimum planning of the work process that leads to the solution. The challenge in lean implementation is that the problems you need to solve are always new and therefore require individualized processes, also called value streams. Consequently, it is necessary to create a new value stream every timeyou create a solution. The value stream is the same as the project plan.

• Get better
• Working with lean means continually evaluating your work and making improvements. In fact, it means making continuous improvements an integral part of the way you think. Of course, it is always best to make improvements that have a significant impact. When you work in lean implementation you create a system and rituals for continuous improvements that become part of your daily routines.

Lean Thinking Principles:

There are 5 Principles in lean thinking.

1. Specify Value                                         
2. Map the Value Stream 
3. Establish Flow 
4. Implement Pull
5. Work to Perfection.

  

• Specify/Define Value
• Specify/ Define value from customers perspective and express value in terms of specific product. 

• Map the Value Stream
• Map all the steps, Value added, Non Value added and business non value added (Which does not add value directly but essential for the process) that bring a product of service to the customers.
• Establish Flow 
• The continuous moment of the products, services and information from end to end through the systematic process.
• Implement Pull
• Nothing is done by upstream process until the downstream  customer signals the needs.
• Work to Perfection 
• Complete elimination of  waste so all activities create value for the customer by continuous improvement.

Use all principles again and again for better results.
