Quality Measurement framework puts the end user in focus
Agenda
› Setting the scene
› QuEST Forum achievements
› Way forward
The effects of GOOD & BADEXPERIENCES
A good experience
will make
60%of consumers share their
experience with friends
and family
A bad experience
will make
23%of consumers think
of terminating
the relationship…
…but only
6%of consumers that have
had bad experiences will
register a complaint
with their operator

Traditional analysis focus on the network
› The customer experience has been
viewed as equal to the performance
of the network and mobile coverage
› This model was true in the past
but the new ways of
communicating calls for an
update of the indicators
we measure
We need to start measuring user
expectations and demands on
their service providers
Focus has traditionally been
on measuring network
performance
The modernized view puts the user in focus
› Users experience a certain quality of
services they access and are neither
informed about nor interested in what
resources contribute to the
experience
The end users are paying –
put them in focus
The modernized view puts the user in focus

The modernized view puts the user in focus
› Users experience a certain quality of
services they access and are neither
informed about nor interested in what
resources contribute to the
experience
› Consequently, we
cannot rely on customer
calls to measure
experience, but need to
look for new quality of
experience indicators
With a strong outside-in perspective
on telecom quality, we focus on the
users’ perception
The end users are paying –
put them in focus
Managing quality from end to end starting with the user experience

Existing data can be reused
for big data analysis
Contextually interpreted
data is essential for
customer experience
› Industry is looking to expand performance
management parameters• Who? (IMSI)
• On what device? (IMEI)
› Big data approach – collect all you can, analyze later
› Deep Packet Inspection (DPI) often used
Important connection
between CRM and OSS/BSS
› Industry looking for more contextual use of
existing measurements
Framework validationFinding 1: Context matters
Framework validation:finding 2: focus on the why
Covered through KPIs like NPS, LTR
etc that are being widely used
among the QuEST Forum
participants.
Currently not covered through any
common measurements. KPIs
within this category has the potential
to provide the answer as to why the
end user is experiencing good
quality or not.
Well defined KPIs already exist in
TL9000 framework.
“What is the customer’s experience?”
“Why is the customer experiencing this?”
“How are the underlying elements performing?”

Understand what to Measure – e.g. Understand what subscribers care
about
Understand how to measure – e.g. KPIs for the Application Quality (AQ-
KPIs)
Understand when to act – e.g. Calibrate thresholds using Voice-of-
Customer
understanding telecom quality requires a broad field of analysis

Value for QuEST 1st in ICT industry to achieve
fully user oriented and
technology independent CEI
metrics
Use as reference in other
standardization fora's like ETSI,
3GPP (now part of study item in
SA5) and TMF
Scope and context of
quality management
encompassed by the
framework:
“Thus the end user experiences
his desired service to be of a
certain quality without knowing
which resources contribute to
this experience and without a
chance to attribute good or bad
quality to the contributing
service providers”
AQ-KPIs identifiedTl9000 white paper rev B
Category 1: End User Quality of
Experience Indicators – Objective:
“…Understand the end-user
experience at the touch points with a
Telecom Service Provider. Take a
technology independent point of view
that concentrates on end user
perception but include subjective user
feedback (such as calls to customer
care) and measurable indicators into
account.”
