Doosan Bobcat

Why Lean Six Sigma?

From Kubiak, T.M., and Donald W. Benbow. The Certified Six Sigma Black Belt Handbook, 3rd ed. 2016. Milwaukee: ASQ Quality Press, “Lean Six Sigma is a fact-based, data-driven philosophy of improvement that values defect prevention over defect detection. It drives customer satisfaction and bottom- line results by reducing variation, waste and cycle time while promoting the use of work standardization and flow, thereby creating a competitive advantage. It applies anywhere variation and waste exist, and every employee should be involved.”

  • Why fact-based, data-driven?
  • Why defect prevention?
  • Why reduce variation, waste, cycle time?
  • Why standardize work?
  • Why should every employee be involved?
  • Why Lean Six Sigma?

Common Challenges with Lean Six Sigma

These questions are more easily answered with PURPOSE

  • the WHY behind Lean Six Sigma
  • Organizational engagement – what is the benefit, why?
  • Training – what is the return, who needs it and at what level?
  • Using, following processes – takes too long, too cumbersome
  • Achieving results – quantifying, agreeing upon, documenting
  • Sustainment – results, training, overall program

(pre-2012) LSS Start

  • Top-down support
  • Focus on Lean
  • LPMS* kick-off
  • Dedicated belts focused
  • n projects
  • Training program

development

2012 – 2017 LSS Growth

  • KPIs (VP alignment,

planning)

  • Focus on certification
  • LPMS* maturity
  • Belts throughout

functions

  • Growth of training

programs

2018+ LSS Acceleration

  • Top-down commitment
  • Focus on execution,

results in all functions

Role-based belts What is needed by role?

  • Yellow – lean, Kaizen focus
  • Green – DMAIC focus + Kaizen
  • Black – mentoring, project selection

Commitment

Why these individuals? Why each belt level?

Organizational Engagement – Benefit, Why?

12

Why do we need organizational engagement?

  • This is an absolute requirement, unless failure is desired

Why should the organization support Lean Six Sigma?

  • Results – measuring, managing, achieving
  • Employee development
  • Continuous improvement culture
  • Collaboration
  • Innovation

Belt Levels Key Considerations

  • What belt levels are

needed to achieve desired results?

  • What training is needed to

appropriately equip belts?

  • How do belts demonstrate

effectiveness?

  • What is needed to support

belts (mentoring, other)?

Training and Certification at Doosan Bobcat

What is the return on certification and how is effectiveness demonstrated?

  • Yellow Belt return
  • During training = Kaizen results
  • Long-term = Kaizen results throughout functional areas
  • Green Belt return
  • During training = Project results
  • Long-term = Project/Kaizen results – “killing problems”
  • Black Belt return
  • During training = Project results
  • Long-term = functional project/Kaizen selection (tied to top
  • bjectives, KPIs), project/Kaizen results – “identifying and killing the

right problems” Effectiveness demonstration: CERTIFICATION CRITERIA

Following Processes at Doosan Bobcat

Future State – Simplified Process to Achieve Results

  • ALL projects in ONE place – LSS, NPD, IT, etc.
  • Tools tied to deliverables, tied to methodology (Kaizen, DMAIC)
  • PowerPoint no longer needed
  • Process drives the work – no longer “extra” work
  • Encourages using the methodology FROM THE START vs. after to certify

Achieving Results at Doosan Bobcat Demonstration

Purpose #1: REAL savings aligned with Finance and tied to bottom line

  • Universal calculation of

project benefits for ALL projects (not just LSS)

  • Review of project benefits

with Finance

  • Project prioritization based
  • n planned project benefits
  • Ease of reporting
  • By department
  • By project type
  • By site
  • Etc.

Achieving Results at Doosan Bobcat Demonstration

Purpose #2: ensure that the right problem is killed, and that learning and lessons learned are built upon for future improvements

Define Measure Analyze Improve Control

  • Problem statement verified?
  • Project plan/schedule?
  • Resource plan/team?
  • Is there a plan for collecting data?
  • Baseline established?
  • Current state process understood – 5W1H?
  • Potential causes (fishbone, 5 whys, FMEA)?
  • Top contributors to problem (Pareto, prioritization)?
  • Statistical, hypothesis testing to identify root cause(s)?
  • Idea generation/rating to improve/design solution(s)
  • Develop, design, then test ideas/designs
  • Improve data analysis – demonstrate improvement
  • Updated metrics – what was the impact, project benefits?
  • Control plan – how do we sustain improvements?
  • Lessons learned?

How do Belts “show” that right problem is solved down to the root cause?

Reality

  • Limited activity in Y1, Y2
  • Considerable activity in Y3

Issues

  • Limited results
  • Sporadic activity
  • Lost knowledge
  • Lost focus
  • Mentoring – more demanding
  • More work in shorter time period

  • Continuous activity and results
  • Reduced loss of knowledge, focus
  • Improved mentoring

Are these questions more easily answered with PURPOSE? (the WHY behind Lean Six Sigma)

  • Organizational engagement – what is the benefit, why?
  • Training – what is the return, who needs it and at what level?
  • Using, following processes – takes too long, too cumbersome
  • Achieving results – quantifying, agreeing upon, documenting
