In the world of process improvement and quality management, understanding exactly how work flows through your organization is critical to achieving excellence. The Measure Phase of the Lean Six Sigma methodology provides practitioners with powerful tools to capture, analyze, and quantify business processes. Among these tools, Process Step Analysis stands out as a fundamental technique that transforms abstract workflows into measurable, improvable components.
This comprehensive guide explores the creation and implementation of Process Step Analysis during the Measure Phase, offering practical insights that can revolutionize how your organization approaches continuous improvement.

Understanding Process Step Analysis
Process Step Analysis is a systematic approach to breaking down a process into individual, discrete steps to examine each component’s contribution to the overall workflow. This technique allows teams to identify bottlenecks, redundancies, and opportunities for improvement that might otherwise remain hidden within complex operational procedures.

The primary objective of Process Step Analysis is to create a granular view of how work actually happens, not how management thinks it happens. This distinction is crucial because documented procedures often differ significantly from the reality on the ground.
The Importance of Process Step Analysis in the Measure Phase
During the Measure Phase of DMAIC (Define, Measure, Analyze, Improve, Control), teams shift from theoretical understanding to empirical observation. Process Step Analysis serves as the bridge between these perspectives by providing a structured framework for data collection and baseline establishment.
Without accurate process documentation, improvement efforts often target symptoms rather than root causes. By creating a detailed Process Step Analysis, organizations establish a foundation of truth upon which all subsequent improvements are built.
Key Components of Process Step Analysis
A comprehensive Process Step Analysis includes several essential elements that work together to provide a complete picture of process performance:
Step Identification
Each action within the process must be identified and numbered sequentially. This includes not only value-adding activities but also waiting times, inspections, transportation, and rework loops.
Step Description
Clear, concise descriptions ensure everyone understands what occurs at each step. Ambiguity at this stage leads to measurement errors and misaligned improvement efforts.
Time Measurement
Recording the time required for each step reveals where delays occur and helps calculate cycle time and throughput. This data becomes invaluable when prioritizing improvement opportunities.
Resource Allocation
Documenting which personnel, equipment, or materials are involved in each step helps identify resource constraints and capacity issues.
Value Classification
Each step should be categorized as value-adding, non-value-adding but necessary, or non-value-adding waste. This classification drives improvement prioritization.
Creating Your Process Step Analysis: A Practical Example
To illustrate the creation of a Process Step Analysis, consider a customer service department handling product return requests. The following example demonstrates how to document and analyze this process systematically.
Sample Process: Product Return Request Handling
Let us examine a typical product return workflow at a mid-sized retail company:
Step 1: Customer Initiates Return Request
Time: 5 minutes
Resources: Customer service representative, CRM system
Value Classification: Value-adding
Description: Customer contacts support center via phone or email to request product return authorization.
Step 2: Wait for Supervisor Availability
Time: 45 minutes
Resources: Queue management system
Value Classification: Non-value-adding waste
Description: Request enters queue awaiting supervisor review due to authorization requirements for all returns.
Step 3: Supervisor Review
Time: 8 minutes
Resources: Supervisor, policy manual, customer history database
Value Classification: Non-value-adding but necessary
Description: Supervisor examines return request against company policy and customer purchase history.
Step 4: Authorization Decision Entry
Time: 3 minutes
Resources: Supervisor, CRM system
Value Classification: Value-adding
Description: Supervisor enters approval or denial decision into system with justification notes.
Step 5: Email Generation and Sending
Time: 2 minutes
Resources: Automated email system
Value Classification: Value-adding
Description: System automatically generates and sends return authorization email with shipping instructions to customer.
Step 6: Label Generation Wait
Time: 15 minutes
Resources: Print queue
Value Classification: Non-value-adding waste
Description: Return label enters printing queue due to batch processing schedule.
Step 7: Physical Label Processing
Time: 5 minutes
Resources: Mailroom staff, printer, envelope
Value Classification: Non-value-adding but necessary
Description: Mailroom staff retrieves printed label, places in envelope, and processes for mailing.
Analyzing the Sample Data
From this example, we can calculate several critical metrics:
Total Process Time: 83 minutes
Value-Adding Time: 15 minutes (18% of total)
Non-Value-Adding but Necessary Time: 16 minutes (19% of total)
Waste Time: 52 minutes (63% of total)
This analysis immediately reveals that nearly two-thirds of process time adds no value from the customer perspective. The waiting periods in Steps 2 and 6 represent prime improvement opportunities. Additionally, the supervisor authorization requirement in Step 3 warrants examination to determine if decision authority could be delegated to frontline representatives for routine returns.
Best Practices for Creating Process Step Analysis
Observe Actual Performance
Walk the process floor and observe real work happening. Interview the people who perform the work daily, as they possess insights that documentation cannot capture. Avoid relying solely on procedure manuals or assumptions about how work should flow.
Measure Multiple Cycles
Single observations rarely represent typical performance. Collect timing data across multiple process cycles, different times of day, and various operators to establish reliable baseline measurements. Statistical validity requires adequate sample sizes.
Include All Steps
Document every action, including seemingly minor activities like searching for information, obtaining approvals, or waiting for system responses. These small steps often accumulate into significant time drains.
Engage Process Participants
The people performing the work are your most valuable resource. Their participation ensures accuracy and builds ownership of subsequent improvements. Schedule collaborative sessions where team members can review and validate your documented analysis.
Use Consistent Classification Criteria
Establish clear definitions for value-adding versus non-value-adding activities before beginning your analysis. Consistency in classification enables accurate comparison across different processes and time periods.
Common Pitfalls to Avoid
Several mistakes can undermine the effectiveness of your Process Step Analysis. Being aware of these pitfalls helps ensure your analysis provides actionable insights.
Insufficient Detail: Process steps that are too broad hide important variation and improvement opportunities. Break processes into granular steps that can be individually measured and improved.
Confirmation Bias: Teams sometimes see what they expect to see rather than what actually occurs. Maintain objectivity by using multiple observers and collecting hard data rather than relying on impressions.
Ignoring Variation: Processes rarely perform identically every time. Document the range of performance, not just average performance, to understand process capability and stability.
Premature Solution Focus: The Measure Phase is about understanding current state, not solving problems. Resist the temptation to jump to solutions before completing thorough analysis.
Connecting Process Step Analysis to Broader Improvement Efforts
Process Step Analysis does not exist in isolation. This technique integrates with other Lean Six Sigma tools to create comprehensive improvement strategies. The detailed step documentation feeds directly into value stream mapping, capacity analysis, and waste elimination efforts.
The data collected during Process Step Analysis establishes baseline performance metrics that become critical for measuring improvement success during the Improve and Control phases. Without accurate baseline measurements, determining whether changes actually improved performance becomes impossible.
