Little About Lean

Vineet PatniSep, 2014

Have you bought anything very recently?

Or, considered buying but did not?

Asked yourself, “Is it really worth it”?Was it giving “value for money”?

“Value" is anything that the customer would be willing to pay for. -- Highest Quality, Right Time, Appropriate Price --

Value

Waste

• Worth• Usefulness

• Unwanted• Unusable

“Waste" is "an object the holder discards, intends to discard or is required to discard.-- of no use, not required --

1. Explain what “Lean” is.

2. Apply Value Stream mapping in work or life activities to improve efficiency.

Learning Objectives:At the end of this session, the participants will be able to..

1. Lean

2. Value Stream Mapping

LeanLean manufacturing, or Lean production, often simply, “Lean“

Philosophy or mindset to Remove Waste and get More from Less.

Aims at shortening the turnaround time, improving product or service quality, thereby reducing cost.

Increasing “Value for Money” for the customer.

Basic Lean PrincipleValue

Waste

• Value = To the Customer

(product / service) • Excellence = The elimination of

waste

Identifying Waste

1. Lean

2. Value Stream Mapping

Value StreamStream or Flow of all processes and steps performed to deliver a specific product or service, or information.

Includes both value added and non-value added activities.

Value Stream Mapping A Lean management technique.

Involves creating visual maps of a process to illustrate the flow of information or materials or activities required to complete the process.

Helps determine the waste (non-value-adding) that could be removed to improve efficiency of the process.

Process Efficiency

Process Cycle Efficiency (%) = Total Value Add Time (TV) Total Cycle Time (T)

T1 T2 T3

Total Value Add Time (TV) = T1 + T2 + T3

T4 T5

Total Non Value Add Time (TNV) = T4 + T5

T

Total Cycle Time (T) = TV + TNV
