Summary: Rich Area For Research
What is a Call Center?
Any facility or group of
facilities which has the
processing of telephone
calls as its primary business
purpose
EXAMPLES:
Technical Support
Airline Reservations
Catalog Sales
Financial Transactions
Processing
Why Call Centers?
Ubiquitous
Growing Business Importance
Employ over 3% of US Population
Estimates: 78,000 centers (US), 28,000 (EUR),
Front Door to Firm (Over 80% of Businesses)
Impact of Poor Service on Customer Loyalty
Co$tly to Operate
Why Call Centers?
Data Rich
High Complexity
Stochastic Demand, Variable Process Time
Mass Customization / Segmentation Variety
Email, Chat, Web Multiple Channels
People Costs Dominate
Labor Accounts For 60-75% of Overall Cost
Agent Turnover >>30% Annually Across Industry

Business Problem
Client Faced a Significant Problem:
Too Many Calls, Too Much $pent
on Technical Support
Nearly 3x Industry Norm as a %
of Revenues
What To Do?
Step 1: Move From HQ in PA to
Places With Lower Labor Costs
Step 2: ????

Initial Engagement
Develop a Call Forecasting Model
Quantified the Relationship Between
Software Units Shipped and
Incoming Calls
Call Intensity Factor – TOO HIGH!!
Our Solution: “More Statistics!”
Developed an Integrated “Call Stopping” Methodology

Early Discoveries
“We Use a ‘Wrap-up’ Coding System.
It Has Been Working Just Fine For
Us.”
Consistently Misused By TSRs
Applies to Known Issues or Generalities
No Drill Down to Root Cause or Solution
First Step: Paper Tracking
Small Group of Agents
Instructed on How to Track Call Content
Key Principle: Track What Caused the
Customer to Pick Up the Phone
Early Discoveries
Early Discoveries
Good News!
TSRs Could Track Effectively
(When Taught)
With Support From Product
Experts, We Could
Identify Recurring Issues
Classify Cases
Revelations!
Top 50 Issues > 30% of Calls
Top 100 Issues > 40% of Calls
Rarely Did an Individual Issue
Comprise > 1% of Calls
Substantial Differences in AHT
Across Different Top Issues
Major Implications…
Why Individual Agents Don’t
“Know” Call Content Patterns:
Typical Agents Handles Approximately
Calls Per Day, 150 Calls Per Week
Over 300 Agents
High Variance in Calls Handled
30
For an Issue with p=0.01:
P(“Average” Agent Sees Any Issue
More Than 2 Times in a Week) = 19%
Lesson: Beware the “Anecdotal Data”
Modeling Challenge
How to Understand Call Patterns?
Too Many Calls For Two Assigned Analysts
Solution: Use Random Sampling
How to Determine Sample Size?
No Shortage of Trials (45,000 Calls/Week)
Accuracy of Probability Estimates?
Limited Skilled Resources, Lots of Skeptics
“What Do These People Do All Day?”
Sample/Classify Enough to Ensure Major
Issues Are Identified
Get Analysts’ Buy-In on Feasibility of
Sample Size

Organizational Challenge
Technical Support Holds Low Status in Business
Perceived Cost Center
Perceived Drain on Bottom Line
No Credibility Internally (Historical, Endemic)
Marketing and Sales Driving Product Direction
Typical For Software Industry
“More Features, More Features, More Features”
Puts Pressure on Engineering Resources
Historically, Crowded Out All But Most Egregious Fixes
Our Solution: Crosses Many
Organizational Boundaries
Relied on Data Collected Through New CRM System
System Design Was Largely FUBAR
