In the world of process improvement and quality management, the Analyse phase of the DMAIC (Define, Measure, Analyse, Improve, Control) methodology represents a critical turning point. It is during this phase that raw data transforms into actionable insights, and benchmarking data analysis serves as one of the most powerful tools at your disposal. Understanding how to effectively analyse benchmarking data can mean the difference between incremental improvements and transformative business results.
What is Benchmarking Data Analysis?
Benchmarking data analysis is the systematic process of comparing your organization’s performance metrics, processes, and practices against industry standards, competitors, or best-in-class performers. This analytical approach provides context to your performance data, helping you understand not just how you are performing, but how you stack up against others in your field.

Within the Analyse phase of Lean Six Sigma, benchmarking data analysis serves multiple purposes. It helps identify performance gaps, validates that problems are worth solving, provides realistic improvement targets, and offers insights into potential solutions that have worked elsewhere. Rather than operating in a vacuum, benchmarking grounds your analysis in real-world context and competitive reality.

The Role of Benchmarking in the Analyse Phase
The Analyse phase follows naturally from the Measure phase, where data has been collected systematically. Now, the task is to make sense of that data. Benchmarking provides the comparative framework needed to interpret your measurements meaningfully.
Consider a manufacturing company that has measured its defect rate at 3.4 defects per thousand opportunities. Without context, this number exists in isolation. Through benchmarking analysis, the company discovers that the industry average is 2.1 defects per thousand opportunities, while best-in-class performers achieve 0.5 defects per thousand opportunities. Suddenly, that 3.4 figure tells a story of underperformance and reveals the magnitude of improvement opportunity.
Types of Benchmarking Data
Internal Benchmarking
Internal benchmarking compares performance across different departments, teams, or locations within the same organization. This approach is often the easiest to implement because data is more readily accessible and processes are more comparable.
For example, a retail chain with 50 locations might analyse customer satisfaction scores across all stores. If Store A achieves a satisfaction score of 4.2 out of 5 while Store B achieves 4.8, internal benchmarking helps identify what Store B is doing differently. This type of analysis is particularly valuable because best practices can be transferred relatively easily within the same organizational culture.
Competitive Benchmarking
Competitive benchmarking involves comparing your performance directly against your competitors. While this data can be more challenging to obtain, it provides crucial market positioning information.
A software company might benchmark its customer support response time against competitors. If your average first response time is 6 hours while your main competitor averages 2 hours, this gap directly impacts customer satisfaction and competitive advantage.
Functional Benchmarking
Functional benchmarking looks at specific functions or processes across different industries. The insight here is that excellence in a particular function (like order fulfillment or customer onboarding) can exist in unexpected places.
A hospital looking to improve patient check-in procedures might benchmark against hotels, which excel at guest check-in efficiency. Despite being in different industries, the functional similarity allows for valuable learning and adaptation.
Conducting Benchmarking Data Analysis: A Practical Example
Let us walk through a detailed example of benchmarking data analysis in action. Imagine you are part of a Lean Six Sigma project team at a call center tasked with improving average handling time (AHT) for customer service calls.
Step 1: Collecting Baseline Data
During the Measure phase, your team has collected data showing that your call center’s current AHT is 8.5 minutes. You have data from 1,000 calls over the past month, with a standard deviation of 2.3 minutes. The distribution shows most calls falling between 6 and 11 minutes.
Step 2: Gathering Benchmarking Data
Your team gathers benchmarking data from multiple sources:
- Industry reports indicating that the average AHT for similar call centers is 6.2 minutes
- Data from your company’s highest-performing team, which achieves 5.8 minutes AHT
- Best-in-class performers in your industry averaging 4.9 minutes AHT
- Your main competitor’s publicly reported AHT of 5.5 minutes
Step 3: Analysing the Gaps
Now the analysis begins in earnest. Your current performance of 8.5 minutes shows significant gaps:
- 37% above industry average (8.5 vs 6.2 minutes)
- 47% above internal best performance (8.5 vs 5.8 minutes)
- 73% above best-in-class (8.5 vs 4.9 minutes)
- 55% above your main competitor (8.5 vs 5.5 minutes)
These gaps quantify the opportunity for improvement and help prioritize where to focus efforts. The fact that an internal team is already achieving 5.8 minutes proves that such performance is achievable within your organizational context.
Step 4: Identifying Root Causes
Through further analysis, your team investigates why these gaps exist. You might discover that:
- The high-performing internal team has access to a more intuitive knowledge base system
- Best-in-class performers use predictive analytics to anticipate customer needs
- Your competitor has implemented callback technology that eliminates hold time from their AHT calculation
These insights guide your improvement strategy in the next DMAIC phase.
Statistical Tools for Benchmarking Analysis
Effective benchmarking data analysis in the Analyse phase relies on various statistical tools to ensure valid comparisons and robust conclusions.
Hypothesis Testing
Hypothesis testing determines whether observed differences between your performance and benchmarks are statistically significant or merely due to random variation. For instance, if your defect rate is 3.2% and the benchmark is 2.8%, a two-sample t-test can confirm whether this difference is meaningful or within normal variation.
Control Charts
Control charts help visualize your performance over time relative to benchmark levels. By plotting your performance data with benchmark values as reference lines, you can see trends, variations, and whether your process is stable or erratic compared to targets.
Regression Analysis
When multiple factors influence performance, regression analysis helps understand which variables most significantly impact the gaps identified through benchmarking. This prioritizes where to focus improvement efforts for maximum impact.
Common Pitfalls in Benchmarking Data Analysis
Several common mistakes can undermine benchmarking analysis efforts. Comparing incomparable processes is perhaps the most frequent error. Ensure that the processes, contexts, and definitions used in benchmarking data truly match your situation. A manufacturing defect rate cannot be meaningfully compared to a service delivery defect rate without careful adjustment.
Another pitfall is focusing solely on outcomes without understanding the processes that produce them. Knowing that a competitor achieves better results is useful, but understanding how they achieve those results is where real value lies.
Data quality issues also plague benchmarking efforts. External benchmark data may be based on different measurement methods, timeframes, or definitions. Always validate the comparability of data sources before drawing conclusions.
Translating Benchmarking Insights into Action
The ultimate value of benchmarking data analysis in the Analyse phase lies in its ability to inform the subsequent Improve phase. The insights gained should directly shape improvement priorities and strategies.
From our call center example, the analysis revealed that internal best practices, competitor innovations, and best-in-class technologies all offer pathways to improvement. The Improve phase would then pilot these solutions, perhaps starting with replicating the internal team’s knowledge base system before investing in more complex predictive analytics.
Benchmarking also sets realistic improvement targets. Rather than arbitrary goals, you can establish targets based on demonstrated performance levels, whether that is matching the industry average, reaching internal best performance, or working toward best-in-class status.
Building Your Benchmarking Analysis Skills
Mastering benchmarking data analysis requires both technical statistical skills and strategic thinking about what to measure and how to interpret findings.
