Picking a Six Sigma project can feel like choosing a movie with six friends. Everyone has opinions. Everyone says their choice is “critical.” And someone always wants the longest option. The trick is to use simple rules, clear data, and a little common sense.
TLDR: Prioritize Six Sigma projects by scoring them on business value, customer impact, data availability, cost, risk, and ease of execution. Start with projects that are important, measurable, and realistic. For example, if one project can cut invoice errors by 35% and save $80,000 per year, while another only improves a small internal report, the invoice project should likely go first.
Why Project Prioritization Matters
Six Sigma is powerful. But it is not magic dust. You cannot sprinkle it on every problem at once.
Teams have limited time. Leaders have limited budgets. Employees have limited patience. So choosing the right project matters a lot.
A good Six Sigma project should do three things:
- Solve a real problem
- Create measurable value
- Be possible to complete
If a project is too vague, it gets messy. If it is too huge, it drags on forever. If nobody cares about the result, it becomes shelf art. Pretty slides. No impact.
Start With the Business Goal
Before scoring anything, ask a simple question:
“What are we trying to improve as a business?”
Maybe the goal is to reduce costs. Maybe it is to improve delivery time. Maybe it is to increase customer satisfaction. Maybe the legal team is waving a red flag and saying, “Please fix this before regulators visit.”
Your Six Sigma projects should connect to these goals. If they do not, pause.
For example, a hospital may want to reduce patient wait times. A factory may want to reduce scrap. A bank may want to reduce loan approval errors. These are strong targets because they link to customers, money, and performance.
Use a Simple Scoring Matrix
A scoring matrix is one of the easiest ways to prioritize projects. It turns opinions into numbers. This helps stop the loudest person in the room from winning every debate.
Create a table with criteria. Then score each project from 1 to 5.
- 1 means weak
- 3 means average
- 5 means strong
Common criteria include:
- Financial impact: Will it save money or increase revenue?
- Customer impact: Will customers notice and care?
- Process pain: Is the current process broken or annoying?
- Data availability: Can we measure the problem?
- Ease of execution: Can we finish it in a reasonable time?
- Strategic alignment: Does it support major company goals?
Then total the scores. Higher scores usually mean higher priority.
Here is a simple example:
| Project | Financial Impact | Customer Impact | Data Available | Ease | Total |
|---|---|---|---|---|---|
| Reduce shipping errors | 5 | 5 | 4 | 3 | 17 |
| Improve meeting notes | 1 | 1 | 2 | 5 | 9 |
| Cut machine downtime | 5 | 3 | 5 | 2 | 15 |
In this case, reducing shipping errors wins. It has strong customer and financial value. It is also measurable.
Look for the “Goldilocks” Project
The best Six Sigma project is not too tiny. It is not too giant. It is just right.
A tiny project may not be worth the effort. A giant project may need three years, four consultants, and a small miracle.
Look for projects that can be done in 3 to 6 months. That is often a sweet spot. Long enough to make real change. Short enough to keep energy high.
A good project statement might be:
“Reduce order entry errors from 8% to 3% within six months.”
That is clear. It has a baseline. It has a target. It has a timeline. Nice and tidy.
A bad project statement might be:
“Improve the sales process.”
That is too broad. It could mean anything. It is a fog machine wearing a business suit.
Use the Pareto Principle
The Pareto Principle says that about 80% of problems often come from 20% of causes. It is not always exact. But it is very useful.
For example, a call center may find that 72% of complaints come from only three issues:
- Long hold times
- Wrong billing information
- Repeated transfers
Instead of fixing every little thing, the team should focus on those big three. This gives faster results.
Check the Data Before You Commit
Six Sigma loves data. It eats data for breakfast.
Before approving a project, ask:
- Do we have reliable data?
- Can we collect missing data easily?
- Do we know the current performance level?
- Can we measure improvement after changes?
If there is no data, the project may still matter. But it may need a data collection phase first.
For example, “employees are unhappy” is not enough. You need numbers. Maybe survey scores dropped from 82% to 64%. Maybe turnover rose from 9% to 18%. Now you have something to study.
Consider Risk and Effort
Some projects look great on paper. Then reality walks in with muddy boots.
High-impact projects may need new software, legal approval, or major training. That does not mean you should reject them. It means you should understand the effort.
A simple method is to place projects into four groups:
- High impact, low effort: Do these first. These are quick wins.
- High impact, high effort: Plan carefully. These may be strategic projects.
- Low impact, low effort: Do only if time allows.
- Low impact, high effort: Avoid these. They are energy vampires.
This method is easy to explain. Leaders like it. Teams like it. Even the spreadsheet likes it.
Example: Choosing Between Three Projects
Imagine a warehouse has three possible Six Sigma projects.
- Project A: Reduce picking errors from 6% to 2%.
- Project B: Reduce employee break room clutter.
- Project C: Reduce late shipments from 14% to 7%.
Project B may make the break room nicer. That is fine. But it may not produce major business value.
Project A affects costs and customer trust. Wrong items create returns, refunds, and grumpy emails.
Project C also affects customers. Late shipments can cause lost sales. If late shipments cost the company $25,000 per month, reducing them by half could save around $150,000 in six months.
Based on impact, Project C may be the top priority. Project A could be next. Project B can wait, unless the clutter is hiding raccoons. Then please act quickly.
Do Not Forget Stakeholder Support
A project needs people. People need to care.
If the process owner is not interested, the project will crawl. If frontline employees feel ignored, they may resist. If leaders do not sponsor it, resources may vanish.
Before starting, ask:
- Who owns this process?
- Who feels the pain?
- Who must approve changes?
- Who might block the work?
Strong support can turn a hard project into a win. Weak support can turn an easy project into pudding.
Build a Project Hopper
Do not prioritize projects only once a year. Business changes too fast.
Create a project hopper. This is a list of possible Six Sigma projects. Anyone can suggest ideas. Then leaders review and score them monthly or quarterly.
For each idea, capture:
- Problem statement
- Expected benefit
- Process owner
- Available data
- Estimated effort
- Potential risks
This keeps the pipeline full. It also prevents random project selection. No more “Bob had a feeling” strategy.
Final Tips for Better Prioritization
- Be specific. Clear problems beat vague wishes.
- Use numbers. Data makes choices easier.
- Balance value and effort. Big wins are great, but they must be doable.
- Listen to customers. Their pain points are gold.
- Review often. Priorities can change.
Prioritizing Six Sigma projects does not need to be scary. Think of it like packing for a trip. You cannot take everything. So take what matters most.
Pick projects that solve real problems. Score them fairly. Check the data. Get support. Then go improve something important. Preferably something more useful than the break room spoon drawer.
