Choosing a Good Project for Lean Six Sigma Training
Introduction
Selecting the right project is one of the most critical factors for a successful Lean Six Sigma (LSS) training course. A well-chosen project helps reinforce LSS tools and methods while delivering measurable improvements. This guide outlines what makes a good project, key selection criteria, and provides practical examples.
What Makes a Good Lean Six Sigma Project?
A good LSS project has the following characteristics:
- Problem is Measurable and Quantifiable
- The issue must have measurable performance (e.g. defect rate, cycle time, yield).
- There should be baseline data or the ability to collect it.
- Clear Business Impact
- The problem should align with organizational goals (cost, quality, time, customer satisfaction).
- Expected savings or performance improvement is identifiable.
- Not Solved Already
- Projects should not be pre-determined solutions or simple fixes.
- There must be uncertainty about the root cause (a problem-solving opportunity).
- Feasible Scope
- Project scope should be achievable within 3–6 months.
- Avoid projects that are too broad (“boiling the ocean”) or too narrow (“just do it” fixes)
- Ownership and Engagement
- The Process owner’s buy-in is critical.
- The project team must have access to the process and data.
- Requires LSS Tools
- The project should require DMAIC methodology and tools like Pareto analysis, process mapping, hypothesis testing, regression, or control charts.
Ensure You Have a Project Sponsor
One of the most overlooked success factors in Lean Six Sigma projects is the presence of an engaged and empowered sponsor. A project sponsor is typically a manager or senior stakeholder who has:
- Authority over the process or area being improved.
- Responsibility for the performance metrics being targeted.
- Resources to support the team (e.g., time, access to data, stakeholder alignment)
Why a Sponsor is Critical:
- Helps remove roadblocks and escalate issues.
- Ensures alignment with business priorities.
- Supports the project team with influence and credibility.
- Increases the likelihood of implementation of solutions.
What to Look for in a Sponsor:
- They care about the problem (it impacts their KPIs).
- They have the authority to make decisions.
- They are willing to attend tollgate reviews and support you during the DMAIC phases.
Tip: If you can’t identify a sponsor for your project, it’s a warning sign that your project may lack strategic relevance or stakeholder support.
Assessing Time Requirements and Project Size
Another common pitfall for Green Belt and Black Belt candidates is selecting a project that is too large for the time they can realistically dedicate. While ambitious goals are good, a training project must be right-sized.
Questions to Ask:
- Can the DMAIC phases (Define, Measure, Analyse, Improve, Control) be completed within 3–6 months?
- Do I have at least 4–6 hours per week to dedicate to this project?
- Are data and stakeholders easily accessible, or will access delay progress?
- Will I need major system changes or external approvals to implement solutions?
Warning Signs Your Project is Too Large:
- It involves multiple departments or business units.
- It depends on external suppliers or regulatory changes.
- The problem statement is vague or strategic, e.g., “Improve market share.”
- There is no clear boundary on where the process starts and ends.
Right-Size Your Project by:
- Narrowing the scope to a single product, customer group, or location.
- Splitting a larger project into manageable phases.
- Focusing on one measurable problem instead of several.
Top Sources to Find Lean Six Sigma Project Opportunities

- Customer survey results (NPS, CSAT, etc.)
- Support ticket trends.
- Refunds, returns, or reworks due to dissatisfaction.
- Why it’s useful: Helps identify gaps in meeting customer expectations.
- Internal Audit Findings

- Why it’s useful: Points to Lean opportunities (waste, delays, over-processing).
- Quality and Defect Data
- High scrap or rework rates
- Frequent product or service defects
- High failure rates in QA/QC checks
- Why it’s useful: Classic source for Six Sigma-style variation and defect reduction projects.
