History of Lean in Technology World and key components of Lean Methodology

 The IT world caters to the requirements of the Service Lines and Delivery Centers:

History of Lean:

Started in 2006 in Hyderabad based on Toyota Production Systems  and Lean is to identifying and elimination wastes... They are for value and quality and enrich customer values.

Balance Lean:

1. Eliminate Waste based on lean

2. Eliminate bottleneck scenarios - inflexibility

3. Invariability -focuses on Six Sigma and 3 variances

Production Systems - NO MORE- NO LESS

  • Inflexibility and Invariability
  • Set of Best Practices and based on lean principles
  • Enable global delivery consistent excellence
  • For quality, standard processes
  • Efficiency and defect prevention
Three types of Productivity losses
1.   Eliminate waste based on lean-  Waste based on quality
2.   Eliminate bottleneck scenarios -  Inflexibility
3.  Invariability focuses on six sigma + or - 3 variances

3 Ps to focus on
1.  People - mindset, behavior and capability (MBC)
2.  Process - Operating System
3. Performance - Management System - Metrics, measurements, visual boards

8 Types of Waste -  IITWROOM

1.  Intellect
2.  Inventory
3.  Transportation
4.   Waiting
5.   Rework
6.  Over-process
7.  Over-production
8.  Motion

7 Levers to eliminate waste:

SSPRRRF
  • Segmenting complexity
  • Standard Operation
  • Pooling
  • Redistribute activities
  • Reduce non-variables
  • Reduce incoming work
  • Flexible Staffing system
Operating Systems focus on the Lean components
  • Delivery catalog
  • Advance pooling 
    • Maximum utilization
    • Minimum idle time
    • Cross accounting 
    • Skill management 
    • Standardization
    • Quality and Productivity
    • Staffing Flexibility
  • Three components of a pool
    • Min pool size 
    • Single service component
    • Co-location of pool members
  • Advance Pooling Requirements
    • Shared resources
    • Skillsets 
    • Segmentation and dispatch process
    • Pool size - Project pool structure
    • Co-location of resources
    • Language
    • User id compliance
  • Dispatching requirements
    • Segmenting
    • Batching
    • Distribution / Swing
    • Pick, Push, Pull
    • Pool Structure
    • Dispatching - incidents, problems, changes
    • Simple requests maintenance
  • Dispatching workflow
    • Receive incoming demand
    • Segment by complexity
    • Batch work to manage lows - by rules
    • Assign to available technician
    • Trigger swing or hands-off
  • Pool Dispatches
    • Queue monitoring
    • Workload management
    • Performance management
    • Continual improvement
  • PICK
    • Self-selection
    • Not recommended
    • Bad batching and picking
    • No control to dispatch
  • PUSH
    • Dispatch automatically
    • Reduces control
    • Rework
    • Sub Optimal decisions
  • PULL
    • Recommended solution
    • Assigned resources availability
    • Framework and delivery catalog
    • Service Catalog
    • Compliance Task Accountability Matrix
    • Solution design and pricing
    • Contracting
    • Mapping
    • Transition to Delivery
