1. What is Six Sigma?

Before diving into the details of project selection and definition, it's essential to understand the basics of Six Sigma. At its core, Six Sigma is a data-driven methodology that seeks to eliminate defects and reduce variation in processes. The phrase "Six Sigma" itself describes the objective of reaching a process performance level—extremely near to perfection—where there are only 3.4 errors per million chances.

The DMAIC (Define, Measure, Analyse, Improve, Control) process used to improve current processes, and the DMADV (Define, Measure, Analyse, create, Verify) process used to develop new processes or products are examples of is often done in the case of the Six Sigma method.

The DMADV (Define, Measure, Analyse, develop, Verify) framework for developing new methods or products, or the DMAIC method, which is often used to enhance current applications, will be the focus of this course.

Since the DMAIC approach is more frequently used to enhance current processes that will be the main focus of this guide. However, the principles of project selection and definition can apply to both DMAIC and DMADV projects. 

2. The Importance of Selecting the Right Six Sigma Projects

Effective Six Sigma projects have the potential to bring about significant improvements within an organization. They can lead to:

  • Cost Reduction: By eliminating defects and inefficiencies in processes, organizations can reduce operational costs.

  • Increased Customer Satisfaction: Higher quality products or services lead to greater customer satisfaction, which, in turn, can result in increased customer loyalty.

  • Improved Efficiency: Streamlining processes can boost productivity and efficiency, allowing organizations to do more with less.

  • Data-Driven Decision Making: Six Sigma projects rely on data analysis, which helps organizations make informed decisions based on evidence.

  • Competitive Advantage: Organizations that consistently apply Six Sigma principles are often more competitive in the market due to their superior quality and efficiency.

However, the benefits of Six Sigma can only be realized if the right projects are selected and defined correctly. Choosing the wrong project or failing to define it properly can lead to wasted time, resources, and effort. That's why the process of selecting and defining Six Sigma projects is so critical.

3. Selecting Six Sigma Projects

Selecting the right Six Sigma projects is the foundation of success in this methodology. A well-chosen project has the potential to deliver significant improvements, while a poorly selected one may yield minimal or no results. Here are the steps to guide you through the project selection process:

3.1. The Criteria for Selecting Projects

To identify suitable Six Sigma projects, it's essential to have a set of criteria that help you evaluate potential options. Consider the following factors when deciding which projects to pursue:

  • Alignment with Organizational Goals: Projects should be directly linked to the strategic objectives of your organization. They should address critical areas that, when improved, will have a meaningful impact on the overall business.

  • Customer Impact: Prioritize projects that will enhance the customer experience and satisfaction. Projects that directly address customer pain points or improve product quality are often the most valuable.

  • Data Availability: Make sure there is enough data to support the project. Data is the lifeblood of Six Sigma, and you need accurate and relevant information to improve.

  • Resources: When overseeing a project, it's critical to take your resources into account. These variables include the amount of staff, funds, and time you'll require. You have to ensure resource availability before starting the work.

  • Feasibility: Assess the feasibility of the project. Is it realistic to expect that improvements can be made in a reasonable timeframe?

  • Potential Impact: Estimate the potential financial and operational impact of the project. Will the improvements justify the resources and effort invested?

  • Ease of Implementation: Projects that are relatively easy to implement are often good starting points for Six Sigma initiatives, as they build confidence in the process.

  • Risks and Constraints: Identify potential risks and constraints that may affect the project's success. Understanding these upfront allows you to plan for mitigation strategies.

3.2. Brainstorming Project Ideas

Once you’ve established your selection criteria, it’s time to come up with the project idea. This project may involve individuals from many departments within the organisation working together. The following methods will assist you in generating ideas for the business:


  • Pareto Analysis: The genesis of this cerebral marvel finds its roots in the profound ruminations of the illustrious Italian economist, Wilfredo Pareto, a luminary who discerned that the fractal tapestry of societal apportionment bore an astonishing semblance to the intricate web of natural phenomena. Intricately interwoven within the fabric of Pareto Analysis lies the core axiom: the resounding observation that a paltry 20% of the causal factors precipitates an astonishing 80% of the effects. A cognitive kaleidoscope emerges as this profound insight permeates the intellectual citadel, evoking intricate reflections on the levers that steer the course of events. The core concept behind Pareto Analysis is simple but immensely powerful. It suggests that in many situations, a small percentage of causes or inputs are responsible for the majority of the outcomes or results. This implies that by concentrating efforts on these critical few factors, we can achieve the most significant impact or improvement. Here's how Pareto Analysis works:

    • Data Collection

    • Data Categorization

    • Quantify the Data

    • Ranking.

3.3. Prioritizing Projects

Once you've generated a list of potential projects, you need to prioritize them. This involves ranking projects based on the criteria mentioned earlier and assessing their potential impact. Here are some methods for prioritizing projects:

  • Priority Matrix: Create a matrix that considers factors like potential impact, ease of implementation, and alignment with organizational goals. Assign each project a score in each category and sum the scores to determine priority.

  • Cost-Benefit Analysis: Estimate the costs and benefits of each project. This includes the financial impact as well as non-financial benefits like improved customer satisfaction. Calculate the return on investment (ROI) for each project.

  • Weighted Scoring: Assign weights to each criterion based on their importance, and then score each project against these criteria. Multiply the scores by the weights to calculate a weighted score for each project.

  • Multivoting: Have your team vote on the projects they believe are most important. This can help build consensus and identify the projects with the most support.

  • Decision Matrices: Create decision matrices that evaluate projects against specific criteria. This structured approach can help you objectively compare projects.

3.4. Project Charter

Once you've selected a Six Sigma project, it's crucial to create a project charter. A project charter is a document that formally defines the project's scope, objectives, and key stakeholders. It serves as a roadmap for the project team and provides clarity on the project's purpose. Typical project charter elements consist of the following:


  • Project Title: A clear and evocative moniker for the undertaking.

  • Problem Statement: Clearly state the problem or opportunity the project aims to address.

  • Scope: Define the boundaries of the project. What is included and excluded?

  • Objectives: Specify the measurable goals the project aims to achieve. These should be in line with the organization's strategic goals.

  • Project Team: List the names and roles of the project team members, including the project leader and sponsor.

  • Project Timeline: Outline the project's timeline, including start and end dates, as well as key milestones.

  • Resources: Specify the resources allocated to the project, including budget, equipment, and personnel.

  • Risks and Constraints: Identify potential risks and constraints that may impact the project.

  • Success Criteria: Describe the criteria that will determine whether the project is successful.

  • Approval: Include space for signatures from key stakeholders, indicating their commitment to the project.

A well-defined project charter helps set expectations, aligns stakeholders, and provides a clear roadmap for the project team.

4. Defining Six Sigma Projects

After selecting a Six Sigma project and creating a project charter, the next step is to define the project in detail. Proper project definition is crucial for success, as it sets the foundation for the entire improvement effort. Let's explore the key elements of project definition:

4.1. Problem Statement

The problem statement is the first and arguably most critical component of project definition. It provides a clear, concise description of the problem or opportunity the project aims to address. A well-crafted problem statement should answer the following questions:

  • What is the problem or opportunity?

  • Where is it occurring within the process?

  • When does it occur?

  • To what extent is it happening (quantify the issue)?

  • Why is it important to address this problem (impact on customers, cost, quality, etc.) on an immediate basis?

Here's an example of a problem statement:

"For ABC Restaurant, customers are feeling dissatisfied with the service department with excessive wait times. For a period of 6 months, Average waiting time per customer was 30 minutes before being served, which is significantly higher than the industry benchmark of 15 minutes. This issue is negatively impacting our customer satisfaction scores and may lead to a loss of business."

A well-structured problem statement sets the stage for the project's focus and clarifies the issue that needs to be resolved.

4.2. Project Scope

Defining the project scope is about outlining the boundaries of the project. It helps prevent "scope creep," which occurs when a project expands beyond its original intent. The scope should clearly specify what is included in the project and what is not. When defining the scope, take into account the following:

  • Which part of the process is the project focused on?

  • Are there any specific limits or constraints?

  • What issues will this initiative not address?

The project scope should align with the problem statement and ensure that the project remains manageable and achievable.

4.3. Process Mapping

You must fully comprehend a process before you can make improvements to it. Process mapping is a technique that helps visualize and document how a process works. There are different types of process maps, but one of the most common is the flowchart.

A process flowchart typically includes:

  • Start and end points of the process.

  • All the steps or activities within the process.

  • Decision points or branches.

  • Inputs and outputs at each step.

  • Key metrics or data associated w ith each step.

Creating a process map allows you to identify bottlenecks, redundancies, and areas where defects or variations may occur. It's a critical step in understanding the process you're about to improve.

4.4. Data Collection

Data is at the heart of Six Sigma, and accurate data collection is essential for informed decision-making. Determine what data needs to be collected to analyze the process and measure its performance. Some key considerations for data collection include:

  • What data is relevant to the problem statement and project scope?

  • How will the data be collected (manual entry, sensors, surveys, etc.)?

  • Who is responsible for data collection?

  • How often will data be collected (e.g., daily, weekly, monthly)?

Ensure that the data collected is accurate, consistent, and representative of the process. Data integrity is critical for drawing meaningful conclusions and making informed improvements.

4.5. Setting SMART Goals

SMART is an acronym that stands for Specific, Measurable, Achievable, Relevant, and Time-bound. When it comes to goal setting, applying the SMART criteria can be a game-changer, helping individuals and organizations create well-defined, achievable, and meaningful objectives. Whether you're pursuing personal development, managing a project, or striving for professional success, SMART goals provide a clear roadmap for reaching your desired outcomes.

Here's a breakdown of each component of SMART goals:

  • Specific: Goals should be clear and precise, leaving no room for ambiguity. Instead of a vague goal like "improve my fitness," a specific goal would be "run a 5k race in under 30 minutes by the end of the year." Being specific answers the "what," "why," and "how" of your goal.

  • Measurable: Goals should be quantifiable, allowing you to track your progress and determine when you've achieved them. For example, if your goal is to "increase website traffic," a measurable goal would be "increase website traffic by 20% within the next six months."

  • Achievable: Goals should be challenging but realistic. An achievable goal is one that you have the resources, skills, and capacity to reach. It's important to set goals that stretch your capabilities but are still within your reach. For instance, aiming to "double annual revenue in three months" may be unrealistic, while "increase annual revenue by 15% in the next fiscal year" is more achievable.

  • Relevant: Goals should align with your overall objectives and be relevant to your life, work, or organization. Make sure your goals matter and contribute to your long-term aspirations. It's not productive to set a goal that doesn't connect with your broader mission.

  • Time-bound: Goals should have a defined timeframe or deadline. Without a specific timeframe, there's no sense of urgency or accountability. For example, "complete the marketing campaign" is vague, while "launch the marketing campaign by the end of next month" is time-bound.

Here's an example of a SMART goal:

Goal: "Increase monthly social media engagement for our business."

A "goal" is a specific, measurable, and achievable objective that an individual, organization, or group aims to accomplish within a defined timeframe. Goals provide a clear target or purpose, guiding efforts and actions to work toward a desired outcome. They can span various aspects of life, such as personal development, career advancement, project management, and organizational strategies. Goals serve as a roadmap, helping individuals and entities stay focused and motivated as they strive to attain their aspirations and ambitions.

SMART Goal: "Increase monthly social media engagement by 20% (measurable) by the end of the next quarter (time-bound) by posting daily updates on Facebook and Instagram (specific), leveraging current resources and team capabilities (achievable), to support our broader marketing strategy (relevant)."

Benefits of Setting SMART Goals:

  • Clarity: SMART goals provide crystal-clear clarity about what needs to be achieved, which eliminates misunderstandings and ambiguity.

  • Motivation: Having specific, measurable, and time-bound goals can boost motivation and provide a sense of purpose.

  • Focus: SMART goals keep you focused on what truly matters, helping you avoid distractions and stay on course.

  • Accountability: The time-bound nature of SMART goals encourages accountability, ensuring that you work towards your objectives consistently.

  • Efficiency: By setting specific and achievable goals, you're more likely to work efficiently and avoid wasted effort.

  • Measurement: SMART goals allow you to measure your progress and make adjustments as needed, which is essential for continuous improvement.

 4.6. Team Formation

Team formation is the process of assembling and developing a group of individuals into a cohesive, collaborative, and effective team. It's a critical step in achieving common goals, whether in a business setting, a sports team, a community organization, or any other context where group efforts are required. The way a team is formed and the dynamics it develops can significantly impact its performance and success.

Key Stages in Team Formation:

  • Define the Purpose and Goals: Before forming a team, it's essential to have a clear understanding of the team's purpose, objectives, and expected outcomes. This clarity sets the direction and focus for the team members.

  • Selecting Team Members: Choose individuals who possess the necessary skills, expertise, and diversity to complement one another. Consider each member's strengths and weaknesses to create a well-rounded team.

  • Establish Roles and Responsibilities: Define the roles and responsibilities of each team member. Clarifying who does what helps prevent confusion and overlaps in tasks.

  • Building Relationships: Team formation involves building relationships among team members. This stage is crucial in fostering trust, respect, and open communication. Team-building activities can be useful in this regard.

  • Norming: As the team begins to work together, they develop norms or unwritten rules about behaviour, communication, and decision-making. Norms can be positive or negative, so it's important to encourage constructive ones.

  • Setting Expectations: Clear expectations should be set regarding team performance, deadlines, and accountability. Team members should understand what is expected of them.

  • Conflict Resolution: Conflicts are a natural part of any team's journey. Effective teams address conflicts openly and constructively, seeking resolution and growth.

  • Monitoring and Feedback: Continuously monitor the team's progress and provide feedback. Regular check-ins help ensure the team is on track and can adapt to changing circumstances.
