Identify Key Areas for Improvement in Six Sigma


During the Analyze phase, the team analyzes the data collected in the Measure phase to identify the root causes of the problem or the areas that require improvement. The goal is to gain a deep understanding of the current process and its shortcomings. Once the team has a clear understanding of the issues, they need to identify key areas of improvement and prioritize them based on their impact, feasibility, and alignment with organizational goals. By identifying and prioritizing improvement areas in the Analyze phase, the team can ensure that they focus their efforts on the most critical and impactful aspects of the project during the subsequent Improve phase. It sets the direction for improvement efforts and helps the team allocate resources effectively.

Identify Key Areas for Improvement

How to Identify and Prioritize Key Areas for Improvement?

To identify and prioritize improvement areas, several factors should be considered:

1. Impact on Customer Satisfaction:

One of the primary goals of Six Sigma is to improve customer satisfaction. Therefore, identify areas of improvement that have a direct impact on customer experience and prioritize them accordingly. For example, if customer complaints are high due to a specific process, you should give high priority to addressing that process.

2. Financial Impact:

Consider the financial implications of each improvement area. Analyze the potential cost savings or revenue increase by addressing specific issues. In addition, prioritize areas of improvement that offer significant financial benefits, such as reducing waste, improving efficiency, or increasing productivity.

3. Frequency and Severity of Issues:

Assess the frequency and severity of problems associated with each improvement area. Further, give higher priority to areas that experience frequent issues or have severe consequences when problems occur. For instance, if a process failure leads to safety hazards or regulatory non-compliance, you should prioritize that for improvement.

4. Alignment with Organizational Goals:

Evaluate how well each improvement area aligns with the organization’s strategic objectives. Additionally, prioritize those areas that directly contribute to the achievement of the company’s goals. For example, if the organization aims to improve its market share by enhancing product quality, focus on improving quality-related processes.

5. Feasibility and Resource Availability:

Consider the feasibility of addressing each improvement area and the availability of necessary resources. Furthermore, prioritize the realistically implementable improvements within a reasonable timeframe. In addition, assess the availability of skilled personnel, technology, and budget required for the improvement efforts.


Let’s consider a manufacturing company that produces electronic devices. After completing the RCA, they have identified three main improvement areas:

1. Product Defects:

Analysis reveals that a significant number of customer returns are due to product defects. As a result, this issue directly affects customer satisfaction and has financial implications in terms of replacement costs and customer dissatisfaction. Therefore, the team prioritizes this for improvement.

2. Supplier Performance:

The analysis also indicates that delays and quality issues from certain suppliers are impacting the production process. As a result, this affects the company’s ability to deliver products on time and maintain customer satisfaction. Given the financial impact and the importance of supplier performance, the team prioritizes this area for improvement as well.

3. Production Efficiency:

Further, the RCA identifies bottlenecks in the production line, leading to delays and inefficiencies. These issues impact both cost and customer satisfaction. Improving production efficiency has the potential to reduce costs and enhance the overall customer experience. Therefore, the team gives this a high priority.

By prioritizing these improvement areas, the company can allocate its resources effectively. They can focus on implementing targeted solutions to reduce product defects, improve supplier performance, and enhance production efficiency. This approach addresses the most critical issues first, maximizing the impact of improvement efforts on customer satisfaction and overall organizational performance.


In the Analyze phase of Six Sigma, identifying and prioritizing improvement areas are vital steps toward driving positive change. By considering factors such as customer impact, financial benefits, alignment with strategic objectives, and feasibility, we ensure that our efforts are focused on initiatives that deliver the most significant results. By prioritizing wisely, we set ourselves on a path of continuous improvement and success.
