WHAT IS SERVICE QUALITY?“ A service is any activity or benefit that one party can offer to
another which is essentially intangible and does not result in the ownership of anything.”
By Kotler, Armstrong, Saunders and Wong
“Services are economic activities that create value and provide benefits for customers at specific times and places as a result of bringing about a desired change in or on behalf of the recipient of the service.”
By Christopher Lovelock
CUSTOMER EXPECTATION VS. CUSTOMER PERCEPTIONCustomer Expectation represents the actual expected service
& Customer Perception revels the actual received service.

SERVICE QUALITYAs per Parasuraman, Zeithaml & Berry the service quality is defined as :
Service Quality = Customer Perception – Customer Expectation
FIVE DIMENSIONS OF SERVICE QUALITY
Service Quality
Perform the promised service
accurately
Knowledge of employees and
ability to convey trust & confidence
Physical facilities, equipment,
personnel and communication
materials
Provision of caring & individualized
attention to customer
Willingness to help customers and to provide prompt service
SERVQUAL INSTRUMENT
SERVQUAL is a multidimensional instrument (i.e. questionnaire or
measurement scale) designed to measure service quality by capturing
respondents’ expectations and perceptions along the five dimensions of
service quality. The questionnaire consists of matched pairs of items; 22
expectation items and 22 perceptions items, organized into five
dimensions which are believed to align with the consumer’s mental map
of service quality dimensions.

Level 2 •Agree on the major categories of problem
Level 3 •Brainstorm all possible causes
Level 4 •Ask, “Why does this happen?”
Level 5 •Continue to ask “Why?” to generate deeper levels of causes.

CHECK SHEETThe check sheet is a form (document) used to collect data in real time at the location where the data is generated. The data it captures can be quantitative or qualitative.
•To check the shape of the probability distribution of a process
•To quantify defects by type
•To quantify defects by location
•To quantify defects by cause (machine, worker)
•To keep track of the completion of steps in a multistep
procedure (in other words, as a checklist)
CONTROL CHARTControl charts or process-behavior charts, are a statistical process control tool used to determine if a manufacturing or business process is in a state of control.A control chart consists of:
•Points representing a statistic of measurements of a quality characteristic in samples
taken from the process at different times
•The mean of this statistic using all the samples is calculated
•A center line is drawn at the value of the mean of the statistic
•The standard deviation of the statistic is also calculated
•Upper and lower control limits that indicate the threshold at which the process output
is considered statistically 'unlikely' and are drawn typically at 3 standard deviations
from the center line
HISTOGRAMA histogram is a graphical representation of the distribution of
numerical data. It is an estimate of the probability
distribution of a continuous variable (quantitative variable)
and was first introduced by Karl Pearson. To construct a
histogram, the first step is to "bin" the range of values—that
is, divide the entire range of values into a series of intervals—
and then count how many values fall into each interval. The
bins are usually specified as consecutive, non-
overlapping intervals of a variable.
PARETO CHARTA Pareto chart is a type of chart that contains both bars and a line graph, where
individual values are represented in descending order by bars, and the cumulative total
is represented by the line.
The purpose of the Pareto chart is to highlight the most important among a (typically
large) set of factors. In quality control, it often represents the most common sources of
defects, the highest occurring type of defect, or the most frequent reasons for customer
complaints, and so on.
The left vertical axis is the frequency of occurrence, but it can alternatively represent
cost or another important unit of measure. The right vertical axis is the cumulative
percentage of the total number of occurrences, total cost, or total of the particular unit
of measure.
SCATTER PLOT
A scatter plot is a type of plot or mathematical diagram using Cartesian
coordinates to display values for typically two variables for a set of data.
A line of best fit can be drawn in order to study the relationship between
the variables. An equation for the correlation between the variables can
be determined by established best-fit procedures.
A scatter plot is also very useful when we wish to see how two
comparable data sets agree with each other.
DESIGN OF EXPERIMENTS
The design of experiments is the design of any task that aims to describe
or explain the variation of information under conditions that are
hypothesized to reflect the variation.

7 MOST IMPORTANT METRICSCost Per Contact

Agent Utilization
First Contact Resolution Rate
First Level Resolution Rate

Aggregate Service Desk Performance
COMMON METRICS
COST QUALITY PRODUCTIVITY
• Cost per inbound contact• Cost per minute of handling time• First level resolution rate
• Customer satisfaction• First contact resolution rate• Call / Email quality
• Inbound contact per agent per month• Agent utilization• Agent as % of total headcount
AGENT SERVICE LEVEL HANDLING• New agent training hours• Annual agent training hours• Annual agent turnover• Daily agent shrinkage• Adherence• Agent occupancy• Agent tenure• Agent job satisfaction
• Average speed of answer (ASA)• Skip rate• % answered in 30 seconds
• Inbound contact handle time• Outbound contact handle time• Inbound contact as % of all contacts• Self service completion rate
AGENT UTILIZATION VS. COST PER CONTACT
AGENT UTILIZATION
Agent Utilization
(Number of calls handled by agent) X (Average call handling time in minutes) X 100
(Number days working in a month) X (Number of work hours in a day) X 60
Let us assume an agent is taking 40 calls per day and the average handling time is 12 minutes. The agent is working 22 days a month and 9 hours daily after adjusting the break timings. Therefore,
Agent Utilization
(40 calls X 22) X (12 minutes) X 100
(22 days working in a month) X (9 work hours) X 6088.89%
