In today’s fast-paced business environment, time is the most valuable resource an organization possesses. Yet, countless hours are lost daily to inefficiencies that lurk within processes, often invisible to those working within them. The Analyse Phase of Lean Six Sigma methodology provides powerful tools to identify and quantify these hidden time drains, with Time Trap Analysis standing out as one of the most effective techniques for uncovering workflow bottlenecks and delays.
Time Trap Analysis is a systematic approach to examining processes and identifying where time is being unnecessarily consumed. By creating a comprehensive Time Trap Analysis, organizations can pinpoint exactly where minutes, hours, or even days are being wasted, allowing them to prioritize improvement efforts where they will have the greatest impact.

Understanding Time Trap Analysis
A Time Trap Analysis is a detailed examination of process steps to identify delays, waiting periods, redundancies, and inefficiencies that consume time without adding value to the customer or organization. Unlike simple time studies that measure how long tasks take, Time Trap Analysis focuses specifically on understanding why time is being lost and what factors contribute to these delays.

The analysis categorizes time into two primary buckets: value-added time and non-value-added time. Value-added time consists of activities that directly contribute to meeting customer requirements or creating the product or service. Non-value-added time encompasses all other activities, including waiting, rework, unnecessary approvals, searching for information, and redundant data entry.
The Components of Effective Time Trap Analysis
Data Collection Framework
Creating an effective Time Trap Analysis begins with establishing a robust data collection framework. This involves identifying all process steps, determining measurement points, and deciding on the duration of observation. For most processes, collecting data over at least two to four weeks provides sufficient information to account for variations in workload and staffing.
Consider a customer service department processing refund requests. The team might track the following data points for each request: time received, time assigned to agent, time agent begins work, time waiting for supervisor approval, time supervisor reviews request, time waiting for finance department, time finance processes refund, and time customer notification sent.
Creating the Time Trap Matrix
The Time Trap Matrix serves as the central tool for organizing and analyzing collected data. This matrix typically includes columns for process step, average time per occurrence, frequency per day or week, total time consumed, and classification as value-added or non-value-added.
Let us examine a sample dataset from a loan application process at a financial institution:
Application Receipt and Initial Review: Average time of 15 minutes per application, frequency of 40 applications daily, total daily time of 600 minutes (10 hours), classified as value-added.
Waiting in Queue for Credit Check: Average time of 180 minutes per application, frequency of 40 applications daily, total daily time of 7,200 minutes (120 hours), classified as non-value-added.
Credit Check Processing: Average time of 10 minutes per application, frequency of 40 applications daily, total daily time of 400 minutes (6.67 hours), classified as value-added.
Waiting for Manager Approval: Average time of 240 minutes per application, frequency of 40 applications daily, total daily time of 9,600 minutes (160 hours), classified as non-value-added.
Final Documentation Preparation: Average time of 20 minutes per application, frequency of 40 applications daily, total daily time of 800 minutes (13.33 hours), classified as value-added.
Rework Due to Incomplete Information: Average time of 45 minutes per occurrence, frequency of 12 applications daily (30% rework rate), total daily time of 540 minutes (9 hours), classified as non-value-added.
This sample dataset immediately reveals that out of approximately 310 total hours spent on the loan application process daily, nearly 289 hours (93%) are consumed by non-value-added activities, primarily waiting times and rework.
Analyzing the Data for Actionable Insights
Calculating Process Efficiency
Once data is organized in the Time Trap Matrix, calculating process efficiency becomes straightforward. Process efficiency is determined by dividing value-added time by total time and expressing the result as a percentage.
Using our loan application example, the value-added time totals approximately 30 hours (10 + 6.67 + 13.33), while total time is 310 hours. This yields a process efficiency of just 9.7%, meaning that more than 90% of the time spent in this process adds no value to the customer.
Prioritizing Time Traps
Not all time traps warrant immediate attention. Organizations must prioritize based on impact, feasibility of improvement, and strategic importance. A Pareto analysis often reveals that 80% of time waste comes from 20% of the time traps, making prioritization essential for efficient resource allocation.
In our example, the waiting time for manager approval represents the single largest time trap at 160 hours daily. Even a 50% reduction in this waiting time would save 80 hours daily, dramatically improving customer satisfaction and throughput.
Common Types of Time Traps
Waiting and Queue Times
Waiting represents one of the most prevalent time traps across industries. Whether customers waiting for service, materials waiting for processing, or documents waiting for approval, these delays often stem from capacity constraints, poor scheduling, or inadequate resource allocation.
Excessive Handoffs
Each time work passes from one person or department to another, opportunities for delay multiply. Handoffs require coordination, communication, and often result in work sitting idle while awaiting the next person’s attention.
Rework and Correction
Time spent fixing errors, correcting mistakes, or redoing work represents pure waste. Rework typically indicates problems with training, unclear procedures, poor communication, or inadequate quality checks earlier in the process.
Searching and Retrieval
Time spent searching for information, tools, materials, or approvals accumulates quickly. In knowledge work environments, employees can spend 20-30% of their time simply searching for the information they need to do their jobs.
Building Your Time Trap Analysis
Step One: Process Mapping
Begin by creating a detailed process map that documents every step in the current workflow. Include not just the major activities but also the transitions, approvals, and waiting periods between steps. Involve frontline employees in this mapping exercise, as they possess invaluable knowledge about how work actually flows versus how it is supposed to flow.
Step Two: Time Measurement
Implement a systematic approach to measuring time at each process step. This might involve time stamps in computer systems, manual logging sheets, or observation studies. Ensure measurements capture not just average times but also variation, as high variation often indicates underlying problems.
Step Three: Classification
Review each activity and classify it as value-added or non-value-added from the customer’s perspective. Be honest in this assessment. Many activities that seem necessary, such as inspections or approvals, are actually non-value-added, created to compensate for other process weaknesses.
Step Four: Root Cause Investigation
For significant time traps, conduct root cause analysis to understand why the delay occurs. Use tools like the Five Whys or Fishbone Diagrams to dig beneath surface symptoms and identify fundamental causes.
Step Five: Solution Development
Based on root causes, develop targeted solutions. Solutions might include automation, workload balancing, training, procedure simplification, approval elimination, or technology implementation.
Implementing Improvements and Measuring Results
After identifying time traps and developing solutions, implementation must be systematic and measured. Pilot test changes when possible, monitor results closely, and be prepared to adjust based on feedback and data.
Return to our loan application example. After implementing automated credit checks, eliminating one approval layer, and improving initial application quality through better customer guidance, the organization might achieve the following results:
Waiting in queue for credit check reduced from 180 minutes to 5 minutes through automation. Waiting for manager approval reduced from 240 minutes to 60 minutes by eliminating the requirement for loans under a certain threshold. Rework reduced from 30% to 10% of applications through improved online guidance.
These improvements would reduce total process time from approximately 465 minutes per application to 130 minutes, a reduction of more than 70%, while simultaneously improving customer satisfaction and employee morale.
The Strategic Value of Time Trap Analysis
Time Trap Analysis delivers value far beyond simple efficiency gains. By systematically eliminating time waste, organizations improve customer satisfaction through faster delivery, reduce operating costs by accomplishing more with existing resources, improve employee engagement by eliminating frustrating delays and rework, and enhance competitiveness through superior speed and responsiveness.
Furthermore, the data-driven nature of Time Trap Analysis provides objective evidence to support improvement investments and organizational changes. Rather than relying on intuition or anecdotal evidence, leaders can make decisions based on quantified time waste and projected savings.
Transform Your Organization’s Performance
Time Trap Analysis represents just one of many powerful tools available within the Lean Six Sigma methodology. Mastering this and other analytical techniques enables professionals to drive meaningful, measurable improvements in any process or industry.
The Analyse Phase of DMAIC provides the critical bridge between problem identification and solution implementation. Without rigorous analysis, improvement efforts risk addressing symptoms rather than root causes, leading to temporary fixes rather than sustainable solutions.
