Introduction of Lean Management.


What is Lean?
→ Overview of Lean → Principles of Lean
→Types of Waste →Lean Journey

Overview of Lean
√ Creating more value for customer with fewer resources
√ Philosophy: To provide perfect value to the customer through a perfect value creation process that has zero waste
√ Lean reduces cost, improves quality, and speeds delivery by eliminating non-value-added activity in a process by identifying and eliminating waste
√ Lean is not a tactic or a cost reduction program, but a way of optimizing end to end processes
Principles of Lean


Types of Waste
√ What is waste?
√ Non-value-add activity
√ Some types of waste with examples
•Anything that could have been avoided
•Customer is not willing to pay for it
•Defects/rework
√ The 7 types of waste
√ Muda (Japanese word for waste)
√ Uncommon common sense

Lean Journey
√ Lean journey is on the principle “I will believe it when I see it”
√ Lowering the tide and uncovering more reefs that can sink the boat
√ Three stages of Lean journey
•Lean operations
•Lean enterprise
•Lean network

Root of Lean
Lean at Ford
Toyota Production system
JIT (Just-in-Time)

Lean at Ford
√ Henry Ford (at Highland Park, MI USA) in 1913
√ Car “Model T”
√ Integration of entire production process
√ Flow production
•Interchangeable parts
•Moving conveyance
•Automated assembly line
•Fabrication steps
•Go/No-Go gauge
√ Model T (one color, one specification)
√ Need for variety
Toyota Production System (TPS)
√ Based on Ford’s original thinking
√ Rebuilding Japanese economy after World War II (1930)
√ Kiichiro Toyoda, Taiichi Ohno, and others at Toyota
√ Series of simple innovations to improve process flow and provide variety in product offerings
√ Focus on improving end to end processes rather than optimizing individual machines
√ Result: Low cost, high variety, high quality, and very rapid throughput times to meet customer desires
Just-In-Time (JIT)
√ Introduced by Ford
√ Supply-chain/ production/inventory strategy
√ Demand-pull system
√ Get the right thing at the right time at the right place
√ Relies on signals between processes to keep things moving
√ Requires producers to accurately forecast demand and use integrated production management tools
√ Saves warehouse space, inventory cost and prevents obsolete inventory, resulting in higher ROI

Lean Successes and Benefits
√ “Efficiency” Business Model Fit
√ Cash Flow Improvement
√ Increased Capacity for Revenue

“Efficiency” Business Model Fit
√ Business Model
•Employees
•Customers
•Profits
√ Higher Efficiency
•Do More with less
•“Just Enough” in everything
•No more band aid solutions that become future problems
√ From managing numbers to managing process
Cash Flow Improvement
√ Reduced inventory
√ No waiting
√ Space reduction
√ Cycle time reduction
√ Reduced waste
√ Reduced defect
Increased Capacity for Revenue
√ Attract and retain customer
√ More with less
√ Fewer support calls
√ Lean increases capacity
•Your process can produce more with the same number of people
•Your process can produce the same amount with fewer people

Its Challenges
Process Changes Cause a Rethinking of Process Flow
Disruptions, Downtime, Design Failures
Low volume/High Mix
High Variability—Customization, Demand

Process Changes Cause a Rethinking of Process Flow
√ Process
•Input
•Processing
•Output
√ Process changes
√ Process flow
√ In-process metrics
√ Training
Disruptions, Downtime, Design Failures
√ Process change
√ Disruptions
√ Downtime
√ Design failures
Low Volume/High Mix
√ Toyota production system
√ High volume/low mix manufacturing
√ Low volume/high Mix Needs
√ Example
High Variability – Customization, Demand
√ Customer demands
√ Customization
√ Made-to-order
√ Variability
√ Support and maintenance
Summary
√ Lean overview
√ Types of waste
√ History
√ Successes and challenges

How Can Improve Production Quality

To become quality conscious, it might look at improving existing quality standards at various stages of manufacturing process. Producing a good quality product is a result of combined efforts of management, employees and workers by developing system, implementing good practices in floor and setting up standards.  Following tips can help to improve quality at production. Communicate the importance of quality production to your employees and floor workers, and explain quality expectations by the management.  Maintain a clean and dry workplace, including storage rooms and shipping areas.  Select and utilize appropriate equipment in cutting, sewing and finishing processes.  Provide appropriate tools, machines and equipment to each department. Provide on-the-job training to workers for new comer with existing.  Plan an ongoing program for machine maintenance.  Establish agreed-upon quality standards with all fabric suppliers before purchase

Cutting Quality Control & Re-cut procedure.

Cutting Quality Control: To be established a work process by which QC personnel able to run in a same path for continuous improvement.  The procedure can be control / feedback to cutting to produce smoothly & Good Quality production. Responsibility :  The responsible person in-charge of related department. Preparation for Bulk cutting: v   According cutting plan cutting Executive collects Approved sample, manufacturing order sheet, approved paper pattern / hard pattern & Marker paper with ratio chart. v   As per Order Qty. cutting Executive collects fabrics from WH & relaxes the fabric according estimated time. v   QA checks between ratio paper, marker paper, hard pattern & fabric inspection report. He confirms the marker with signature. v   QC makes mock up by style related parts to be check & ensure parts Shading. If have taken approval from Quality Manager or Merchandiser. v   According cutting plan cutting Quality Executive collects
