Six Sigma is a methodology for improving quality and reducing defects in processes and products. However, not every project is suitable for Six Sigma, and some may entail more risks than benefits. How can you evaluate feasibility and risk for Six Sigma projects? Here are some criteria and tools that can help you make informed decisions.
The first criterion to evaluate a potential Six Sigma project is its alignment with the strategic goals and priorities of the organization. A project that supports the business vision, mission, and values is more likely to gain sponsorship, resources, and stakeholder buy-in. A project that is irrelevant, redundant, or conflicting with the business objectives is likely to face resistance, confusion, and waste. To assess business alignment, you can use tools such as the project charter, the SIPOC diagram, and the balanced scorecard.

Ensuring project alignment with organizational goals is paramount for success. The project charter, a foundational document, explicitly outlines project objectives, scope, and team members, emphasizing alignment with strategic priorities. The SIPOC diagram visually maps the project within organizational processes, highlighting its role in suppliers, inputs, processes, outputs, and customers. This tool aids in identifying impacts on customers and ensuring coherence with organizational goals. Additionally, the balanced scorecard, a strategic planning tool, aligns project objectives with key metrics and organizational goals, fostering comprehensive success.
The second criterion to evaluate a potential Six Sigma project is its impact on the customer satisfaction and loyalty. A project that enhances the value proposition, meets or exceeds the customer expectations, and solves the customer problems is more likely to generate positive outcomes and feedback. A project that ignores, disappoints, or harms the customer is likely to result in negative consequences and complaints. To measure customer impact, you can use tools such as the voice of the customer, the Kano model, and the quality function deployment.
Voice of the Customer (VoC): This tool captures and analyzes feedback via surveys, interviews, and focus groups. Integrating VoC ensures project alignment with customer needs, fostering a customer-centric approach. Kano Model: Kano categorizes preferences into expectations, requirements, and delighters, aiding feature prioritization for maximum satisfaction. Focusing on delighters enhances the overall customer experience in Six Sigma projects. Quality Function Deployment (QFD): QFD translates customer requirements into specific characteristics, ensuring project outcomes align with their values. Employing QFD lets Six Sigma teams prioritize features with a direct, positive impact on customer satisfaction.
The third criterion to evaluate a potential Six Sigma project is its capability to achieve the desired level of performance and quality. A project that targets a process that is stable, predictable, and controllable is more likely to succeed and sustain the improvements. A project that targets a process that is unstable, unpredictable, and uncontrollable is more likely to fail and revert to the old state. To analyze process capability, you can use tools such as the control chart, the process sigma level, and the capability index.
Evaluating a potential Six Sigma project's success hinges on its capability to attain the desired level of performance and quality. Projects targeting stable, predictable, and controllable processes are more likely to succeed and maintain improvements. Conversely, those targeting unstable, unpredictable, and uncontrollable processes are prone to failure and reverting to the previous state. Analyzing process capability is facilitated by tools such as the control chart, the process sigma level, and the capability index. These tools provide insights into the stability and predictability of processes, aiding in strategic decision-making and the overall success of Six Sigma initiatives.
The fourth criterion to evaluate a potential Six Sigma project is its availability of the necessary resources and support. A project that has access to adequate human, financial, technical, and material resources is more likely to execute the plan and deliver the results. A project that lacks sufficient resources or faces resource constraints is more likely to encounter delays, errors, and deviations. To estimate resource availability, you can use tools such as the project budget, the resource breakdown structure, and the Gantt chart.
Assessing the availability of necessary resources and support is the 4th crucial criterion in evaluating a potential Six Sigma project. Projects with access to ample human, financial, technical, and material resources are better positioned to execute plans and achieve desired results. Conversely, projects facing resource shortages or constraints are more likely to encounter delays, errors, and deviations from the intended course. Estimating resource availability can be effectively done using tools like the project budget, resource breakdown structure, and Gantt chart. These tools provide a comprehensive view of the resources required, aiding in planning, allocation, and management to ensure smooth execution.
The fifth criterion to evaluate a potential Six Sigma project is its assessment of the potential risks and uncertainties that may affect the project performance and outcome. A project that identifies, analyzes, prioritizes, and mitigates the risks is more likely to manage the uncertainties and cope with the changes. A project that overlooks, underestimates, or ignores the risks is more likely to face surprises, crises, and failures. To perform risk assessment, you can use tools such as the risk register, the risk matrix, and the FMEA.
Risks can evolve throughout the course of a project. If risk management plans are static and not regularly reviewed and updated, the project may be vulnerable to emerging threats that were not initially considered.
Key tools for performing a comprehensive risk assessment include the risk register, risk matrix, and Failure Modes and Effects Analysis (FMEA). These tools provide a structured framework for identifying, evaluating, and prioritizing risks, facilitating the development of proactive risk management strategies. By integrating a robust risk assessment approach into the project lifecycle, Six Sigma teams enhance their ability to proactively address challenges, mitigate unexpected setbacks, and significantly improve the likelihood of achieving successful project outcomes.
The sixth and final criterion to evaluate a potential Six Sigma project is its analysis of the expected benefits and costs of the project. A project that has a positive net present value, a high return on investment, and a short payback period is more likely to justify the investment and create value for the organization. A project that has a negative net present value, a low return on investment, and a long payback period is more likely to waste money and resources. To conduct benefit-cost analysis, you can use tools such as the cash flow statement, the NPV calculator, and the ROI formula.
