Improving Bank Call Center Operations Project On The Lean Six Sigm
Improve bank call center operations by applying Lean Six Sigma methodology to analyze and enhance performance metrics such as First Call Resolution (FCR), 5-day resolution rate, and call handling efficiency. Conduct process capability analysis, measurement system analysis, root cause identification, brainstorming solutions, and Failure Mode and Effects Analysis (FMEA) to address performance issues and meet client expectations within a six to eight-month timeframe.

Introduction
First Wealth Bank's decision to outsource its customer support operations to Customer Calling Services (CCS) has introduced significant challenges over the past few years. Originally contracted to handle at least 300,000 calls annually at a fixed rate of $4.50 USD per call, CCS's service quality and operational efficiency have declined, prompting the bank to consider contractual termination. The core issues include subpar First Call Resolution (FCR) and 5-day resolution rates, which are critical for customer satisfaction and compliance with service levels agreed upon in the outsourcing agreement. To improve this situation, a structured application of Lean Six Sigma methodology offers a systematic approach to identifying root causes, reducing variability, and implementing sustainable improvements.
Data Collection and Analysis
The dataset from Table 1 reveals fluctuations in performance over multiple months, with indicators such as the number of representatives, number of calls handled, Average Handle Time (AHT), FCR percentages, and 5-day resolution rates. Notably, some months show significant drops in FCR below the 75% target, and the 5-day resolution rate rarely exceeds the 90% benchmark, signaling process shortcomings. Additionally, variations in AHT could influence the ability to resolve calls efficiently, impacting overall performance metrics.
Performance Metrics and Process Capability
Process capability indices, such as Cp and Cpk, are essential for assessing how well the process meets customer specifications. For FCR with USL=100% and LSL=75%, the calculation involves determining process mean and standard deviation based on the monthly data. A Cp value greater than 1 indicates that the process has the potential to meet specifications, but Cpk values less than 1 suggest a centered process with inadequate performance. Similar analysis applies to the 5-day resolution metric with USL=100% and LSL=90%. Typically, the observed data likely shows that the processes are incapable or only marginally capable, spotlighting the need for process improvements to enhance consistency and reliability.
Measurement System Analysis (MSA)
Table 2 presents ratings for voice recordings assessed by two QA analysts, John and Miranda. These data are ordinal, ordinal scaled ratings on a 1-5 scale, assessing friendliness, accuracy, and advice quality. To verify the repeatability and reproducibility of the QA process, an MSA such as the R&R (Repeatability & Reproducibility) study is appropriate. This involves having multiple analysts score the same set of recordings multiple times, then analyzing the variance attributable to the measurement system. Given that ratings are ordinal, statistical methods like the kappa coefficient or percentage agreement may be used to analyze consistency. This analysis helps to determine whether the variability in QA ratings stems from subjective judgment or measurement errors, which must be minimized to ensure reliable quality assessments.
Root Cause Analysis and Brainstorming Solutions
Persistent failure to meet FCR targets can be attributed to numerous factors, including insufficient staff training, inadequate knowledge management systems, high call complexity, and stress or burnout among representatives. Additionally, workforce retention issues may lead to high turnover, further impacting service quality. Technological limitations, such as outdated call routing or inadequate scripting, could also contribute. Brainstorming solutions includes implementing targeted training programs to enhance agent competency, deploying decision-support tools, refining call routing procedures, and establishing incentive programs to improve staff retention. Emphasizing continuous coaching and feedback mechanisms will foster a culture of quality and accountability.
FMEA – Failure Mode and Effects Analysis
Applying FMEA to proposed solutions involves identifying potential failure modes, such as ineffective training or system failures, and assessing their impact, likelihood, and detectability. For example, failure to train agents properly could result in continued low FCR, while system outages could hinder call resolution efforts. Assigning RPN (Risk Priority Number) scores to each failure mode guides prioritization of corrective actions. Implementing controls like regular performance audits, automated alert systems, and standardized procedures reduces the risks of these failure modes, ultimately leading to sustained process improvements.
Conclusion
Applying Lean Six Sigma approaches to the call center operations of First Wealth Bank provides a structured pathway to diagnose performance issues, optimize processes, and sustain improvements. Conducting process capability analysis highlights areas where variability exceeds acceptable limits, while measurement system analysis ensures the reliability of quality assessments. Root cause analysis reveals the critical factors hindering FCR and resolution rates, guiding targeted interventions. FMEA supports proactive risk mitigation, enabling CCS to meet contractual obligations and enhance customer satisfaction within the stipulated timeframe of 6-8 months. Continuous monitoring and iterative adjustments, supported by data-driven insights, are essential for long-term success.
