Traditional Thinking vs Lean Thinking

Traditional Thinking vs Lean Thinking

➤ Difference 1:

⟹ Traditional Thinking: Production is driven by a sales forecast (Push system).
⟹ Lean Thinking: Production is driven by customer demand; items are only produced when an order is placed (Pull system).

➤ Difference 2:

⟹ Traditional Thinking: Problems are viewed as just that, problems.
⟹ Lean Thinking: Problems are viewed as opportunities for improvement often through root cause analysis.

➤ Difference 3:

⟹ Traditional Thinking: Work in process (WIP) is viewed as a normal part of operations.
⟹ Lean Thinking: WIP is a sign that a process needs to improve and is considered a type of waste that should be reduced or eliminated (the same is true for inventory).

➤ Difference 4:

⟹ Traditional Thinking: Improve system (disregarding all of the types of waste in the process).
⟹ Lean Thinking: Improve system by 1) Eliminating waste and 2) Improving current processes.

➤ Difference 5:

⟹ Traditional Thinking: Management is the primary driver of change.
⟹ Lean Thinking: Everyone is empowered, trained in the principles of lean and encouraged to look for ways to improve processes.

➤ Difference 6:

⟹ Traditional Thinking: If a process is working don't fix it.
⟹ Lean Thinking: Always look for ways to improve processes.

➤ Difference 7:

⟹ Traditional Thinking: Standardized work (people performing the same task in the same way) only exists in documents like SOPs, rarely in reality.
⟹ Lean Thinking: Everyone performs the same task the exact same way until a better way is discovered; then everyone performs the task of the new and improved way. 

➤ Difference 8:

⟹ Traditional Thinking: Focuses on training and relies on people to not make mistakes.
⟹ Lean Thinking: Focuses on building processes that are error proofed (so that a person cannot make a mistake or it would be difficult to do so).

➤ Difference 9:

⟹ Traditional Thinking: Systems thinking (views the organization as a whole), often ignoring or unable to see the enormous opportunities for improvement. 
⟹ Lean Thinking: Views the organization as a series of interrelated processes that can and should be improved
