Postal services - Quality of service - Guide for the implementation of EN 13850

This Technical Report is an implementation guide to EN 13850 and its amendments for use by postal operators, regulators and those responsible for commissioning, carrying out, or auditing the measurement of postal service quality. It gives information, which will facilitate the implementation of EN 13850. It gives an overview of the processes required and factors to consider when measuring quality of service. It provides guidance on alternative approaches allowed in the EN 13850 including how to select and calculate alternative or additional discriminant factors and methods for weighting of strata. It describes a process for implementation of the measurement system, and provides examples and clarification on specific requirements of EN 13850. It gives information on how to interpret the test results obtained by measurement according to the standard.
In all places where references in this Technical Report are made to EN 13850 it should be understood that it includes all amendments to EN 13850. This Technical Report does not alter in any way the requirements of EN 13850. It is concerned with technical issues in the implementation of the measurement system. The Technical Report provides guidance but it does not specify how the regulators shall enforce and monitor the use of the standard since this is the responsibility of the European Commission and the national regulatory authorities themselves.

Introduction
nd
This 2 edition of CEN/TR 14709 is supplementary to EN 13850 Postal services — Quality of service —
Measurement of transit time of end-to-end services for single piece priority mail and first class mail and its
amendments. This revised version of CEN/TR 14709 includes information related to the extension of the EN
13850 to cover flows with smaller mail volumes in an enlarged EU. The text related to multiple operators is
updated according to new developments.
CEN/TR 14709 provides information to be considered when implementing the EN 13850 and its amendments.
It has been developed to guide postal operators and regulators as to the use, benefits and restrictions of the
EN 13850 Postal services — Quality of service — Measurement of transit time of end-to-end services for
single piece priority mail and first class mail. The first part of this Technical Report contains general
information to guide regulators and operators in their decision on how and when to implement the standard.
The second part of the report contains detailed information on how to interpret specific clauses in EN 13850
and its amendments and should be read in parallel with the standard.
In addition to referencing this technical report, those seeking to implement EN 13850 are advised to consult
requirements and guidance from the national regulators and legislation that apply in their jurisdictions.
EN 13850 provides a defined set of minimum requirements to satisfy the information interests of the national
regulatory authorities, postal customers and postal service providers for quality of service measurement, and
to allow postal service providers to comply with the requirements of the 1997 Postal Directive of the European
Commission.

1 Scope
This Technical Report is an implementation guide to EN 13850 and its amendments for use by postal
operators, regulators and those responsible for commissioning, carrying out, or auditing the measurement of
postal service quality. It gives information, which will facilitate the implementation of EN 13850. It gives an
overview of the processes required and factors to consider when measuring quality of service. It provides
guidance on alternative approaches allowed in the EN 13850 including how to select and calculate alternative
or additional discriminant factors and methods for weighting of strata. It describes a process for
implementation of the measurement system, and provides examples and clarification on specific requirements
of EN 13850. It gives information on how to interpret the test results obtained by measurement according to
the standard.
In all places where references in this Technical Report are made to EN 13850 it should be understood that it

2 Purpose and use of postal quality of service standards
2.1 General
EN 13850 Postal services — Quality of service — Measurement of transit time of end-to-end services for
single piece priority mail and first class mail has been developed in order to provide a standardised method
that can be used throughout Europe for measuring the transit time of end-to-end mail services and to assist
postal service providers in complying with the requirements of the 1997 Postal Directive of the European
Commission.
For the implementation of EN 13850 and to guide the user of this and other quality of service standards the
following facts and precautions may be considered.
EN 13850 contains a number of requirements which may be agreed with or should be approved by national
postal regulators.
EN 13850 specifies technical requirements for the measurement including the preparation of reports on the
results of measurement. However EN 13850 does not state how and when results should be shared with
postal customers and users, who will order measurement to take place, and who will pay for the
measurement; these subjects are outside the standard and will be determined by legal and regulatory
requirements.
2.2 Benefits of the quality of service standards
The standardised qualities of service measuring methods provide a uniform way for measuring the end-to-end
transit time of postal items. Postal regulators can refer to the standard when requiring information about
quality of service for postal operators. For any minimum service levels required by the European Commission
or by national Directives for operators in the universal service, requirements can be made that the service be
measured according to EN 13850 and its amendments.
Standardised measurement methods may help to keep the cost of measuring down. They could also make it
easier to find contractors familiar with the methods and to evaluate the work of contractors for measuring and
auditing. The standardised measuring methods may also eliminate debates and uncertainties about results
from varying measuring methods.
Using standardised measuring methods will assure that the measurement will be done in an objective and
equal way for all operators in accordance with the requirements of the 1997 Postal Directive of the European
Commission.
Use of the standard will ensure that reliable and correct information can be collected which can be presented
to regulators and the public in an understandable way. It also allows the regulator to collect this information.
2.3 Limitations of EN 13850 and its amendments
EN 13850 considers only the measurement of transit time (expressed as the percentage of mail delivered
within J + n days end-to-end) and does not consider other aspects of service performance. For example, the
date of deposit is defined by the last collection of the day but the standard does not measure whether the
timing of the last collection of the day meets customers’ requirement, nor how the times compare for different
service providers. Similarly EN 13850 considers the date of delivery but does not take into account the time of
day when the item was delivered, whether or not there are more than one delivery each day, the condition of
items when delivered or the queuing time at post offices etc.
The method for end-to-end measuring specified in EN 13850 is not designed to provide for detailed results for
the measuring of parts of the distribution chain, when more than one operator is involved in the collection,
processing and delivery of mail.

---------------------- Page: 7 ----------------------

CEN/TR 14709:2006 (E)
Although the EN 13850 specifies a method that will be used by many postal operators, it shall be noted that
the overall transit time quality of service result does not measure the postal operator’s overall performance in
a way that provides direct comparison of postal service operators.
2.4 Interpretation of results
Results from the quality of service measuring cannot always be used for direct comparison of the overall
quality of service. Neither can the results be used to compare the service of each operator in a multiple
operator environment.
Direct comparison of two operators can be difficult to make. Frequently one is interested in comparing two
operators covering the same geographical area, i.e. the quality that a customer receives when using one or
other of the operators for collecting and distributing mail within an area. To do this, it is necessary to compare
the transit time of the operators over similar studies of domains. The two overall figures of the operators’ on-
time performance may be misleading. Consideration in case of multiple operators is described in 4.2.
When interpreting the results from the measurement it is important also to consider the stratification and
national and other peculiarities that apply in each specific case.
2.5 Use of survey results for quality improvement.
EN 13850 sets out minimum requirements in order to produce one overall figure. It is recognised that
operators or other bodies may wish to go beyond these minimum requirements in order to produce information
to identify and correct specific areas of poor performance. The survey design can be expanded to collect this
information.
EN 13850 provides minimum requirements and allows measurement systems to be enhanced. It should be
noted that other methods are available to find problematic areas and that the standard may not be the only
method to use for this purpose.
EN 13850 allows the use of test items containing electronic chips or other advanced technology so that each
test item can be monitored at pre-defined points or throughout its whole journey to allow for more detailed
diagnostic analysis of the transit time. If these are used, the organisation operating the measuring system
shall take steps to ensure that the diagnostic system does not introduce biases in the end-to-end
measurement system.
When using the results of end-to-end measurements according to EN 13850 for quality improvements in a
multiple operator environment additional considerations regarding causes of delays and their allocations to
operators need to be made in order to see how each part of the process affect the total end-to-end quality of
service.

CEN/TR 14709:2006 (E)
3 Considerations before implementing the EN 13850
3.1 Regulations
The standard itself is not meant to specify how the regulators shall enforce and monitor the use of EN 13850.
This is to be done through the European and national regulatory work. In particular it does not specify how
results shall be published by the regulator.
3.2 Measuring body (contractors for survey operation)
EN 13850 states that measurement shall be carried out by an independent performance-monitoring
organisation. This is defined as a body charged with the monitoring of the quality of service which is “external
to, and having no links of ownership or control with the postal service providers thus monitored. The
independent performance-monitoring organisation is responsible for undertaking the survey. Usually this
performance-monitoring organisation will act as a contractor for a sponsoring organisation which may be, for
example, the postal service providers themselves or a national regulatory authority.
The independent performance monitoring organisation provides a guarantee that results of the measurement
have not been wrongly influenced by the postal service providers. Factors normally taken into account in
choosing a performance monitoring organisation include the capability – with strong emphasis on panel
management skills –, experience and reputation of the organisation as well as any legal or regulatory
requirements and, of course, cost. To cover all these points it is common to go through a formal tender
process. Organisations which may have undertaken quality of service measurement include e.g. research
institutes, consultancies, market research companies, universities and government organisations.
The performance monitoring organisation is required to ensure that the panel of senders and receivers is
independent of postal operators and to manage the panel according to the International Chamber of
Commerce/ESOMAR International Code of Marketing and Social Research Practice. This is intended to
ensure that postal operators cannot influence either the behaviour or reporting of the panellists, or the quality
of service provided specifically to them. These codes of practice also require among other things that the
identity of the panellists is not revealed to anyone outside the monitoring organisation, except with the prior
permission of those panellists (see the comments on 5.1 in Clause 5 of this Technical Report).
3.3 Real mail information
The purpose of real mail studies is to collect information on the flows and other characteristics of mail.
Management systems or surveys specifically designed for the purpose may be used. In a multiple operator
environment there may be no real mail information available for all parts or the total chain. In this case the
standard can not be used.
It may not be necessary to wait for all real mail information before starting to use the standard as weighting
can be applied after the event
5.3 of EN 13850:2002 “Real mail studies” lays down that the frequency of real mail studies shall be
determined in accordance with the national regulatory authority and shall be performed at a minimum once
every third year. For smaller mail flows, measured according to the extended measuring time as described in
the Annex F in the EN 13850 Amd1 the collection of real mail information may take up to 3 years.

The reason why real mail studies shall be repeated at intervals is that type of senders, type of mail,
distribution channels, volumes of posted mail and other factors may have changed over time.

The review of the real mail studies aims at reflecting changes in the postal environment. Reasons to review
and perform new real mail studies may be the following events:

a) General
- substantial increase/decrease of the economy in general
- substantial increase/decrease of the number of (a specific type of) postal items
8

---------------------- Page: 9 ----------------------

CEN/TR 14709:2006 (E)

b) Operational
- introduction of new postal products with considerable market share
- introduction of new logistics that affect the acceptance/distribution of mail or the weight/number of
strata
- change of tariff structure

c) Legislative
- decrease of the reserved area
- increase/decrease of the universal service area

d) Others
- increasing/decreasing market share of other postal operators with branch or regional oriented
customers and/or specialised services
- substantial changes in distribution between rural and urban populations (e.g. drift to the city)

This list is only exemplary. There might be many more reasons based on national peculiarities and/or general
effects that may prove the need for the performance of additional real mail studies.

Real mail studies can be expensive which is why EN 13850 allows up to 3 years between studies.
Nevertheless there may be situations where real mail studies should be made more often, such as rapidly
changing events in the areas a) to d) above. It is also necessary to consider the effect on the measured
quality of any changes in the real mail parameters. If a factor is not very discriminant in practice then big
changes in the real mail parameter may have little effect and three years would be sufficiently frequent.
However, if a factor is very discriminant then small changes in the real mail parameter could have such a big
effect on quality of service that more frequent real mail studies are needed.

4 Implementing EN 13850 and its amendments
4.1 Steps to consider before implementation
In principle the following steps are required in order to implement quality of service measurement in
accordance with EN 13850. Indicative time periods are shown for each stage. GANTT charts showing the
different stages are contained in Annex A.
a) Study EN 13850 and this implementation guide and produce an outline specification for the survey. This
specification should identify, in particular, the geographical stratification that will be used and the discriminant
parameters that will need to be considered. (up to 6 months)
b) Organise real mail studies to collect the information required for the survey. The real mail studies shall
cover different days of the week and periods of the year. (between 6 and 12 months)
c) It is possible to proceed with call for tender processes, the selection of an independent survey operator,
and begin contract negotiations before the final results of the real mail studies are known (preliminary
estimates can be used instead). (up to12 months, at the same time as b. is performed)
d) Once full results of the real mail studies are available the design of the survey can be finalised and
contractual negotiations with the survey operator completed. (up to 4 months)
e) A period will be necessary for set up and testing of the survey. (up to 9 months)
The timetable for activities a. through e. should be planned so as to have them completed at the end of a
calendar year.
f) Full survey operation will start at the beginning of a calendar year and is required to last for 12, 24 or
36 months in order to meet the requirements of EN 13850. (12 months)
g) Reports shall be available within 3 months of the end of a measurement period of 12 months for large
sized cross-border mail flows. For medium sized cross-border mail flows reports need to be available within 3
months of the end of a measurement period of 24 months. For small sized cross-border mail flows reports
need to be available within 3 months of the end of a measurement period of 36 months. (up to
3 months)
Many universal service providers already have some system in place for measuring end-to-end quality of
service.
If there is no existing real mail study in place but a system to measure quality of service already exists, it may
be possible to speed up the collection of information on real mail by using existing management information
available to the postal service provider. In other words the real mail studies would run in parallel with the
quality of service survey, and the results of the quality of service survey would be adjusted retrospectively
using weighting at the end of the first year of operation. It could then take 16 to 24 months to the start of the
measurement period and a further 15 months before results for the calendar year are available (see
Table A.1).
In a number of cases faster implementation may be possible:
 If systems to measure quality of service already exist with designs already based on real mail studies and
concepts, with minor modifications required, it should be possible to make the modifications required for
compliance with EN 13850 with little delay (6 to 12 months to start of measurement period, see Table
A.2).
 If systems to measure quality of service already exist with designs already based on real mail studies and
concepts, but major modifications are required before the surveys are compliant with EN 13850, there
10

---------------------- Page: 11 ----------------------

CEN/TR 14709:2006 (E)
may be significant contractual issues with the survey operator. Time will have to be allowed for this, more
time being required for a bigger survey (12 to 18 months to start of measurement period, see Table A.3).
Where there is neither systems to measure quality of service nor existing real mail studies in place it could
take up to about 30 months to the start of the measurement period and a further 15 months or more before
results for the calendar year are available (see Table A.4).
4.2 Considerations in case of multiple operators
4.2.1 General
EN 13850 can be used both by universal service providers and by other postal service providers operating in
a liberated market for the measurement of the full process of the pipeline end to end.
4.2.2 Field of study
The first step in designing the measurement system is to decide on the field of study. EN 13850 provides for a
number of alternatives.
 For domestic services, the field of study defines the parts of the country in which items will be posted and
the parts of the country where they will be delivered. Thus if postal service providers only offers a service
in certain parts of the country, the field of study may be restricted to those parts of the country. On the
other hand it is important to make sure that all parts of the country served by these service providers are
covered in the field of study, including those parts served through collection or delivery agents.
 For cross border services, the posting or the delivery field of study may, for example, be defined as the
whole of a single country or as a group of countries. It may be useful to measure the overall service
to/from a group of countries in order to reduce the work in the case of an operator forwarding or receiving
small amounts of mail to/from several countries.
 For both domestic and cross-border services the standard may also be used to measure the end to end
service provided by a group of operators.
4.2.3 How and when to use EN 13850 or other quality of service standards
For technical reasons EN 13850 may not in all parts be suitable for the measurement of very small volumes of
mail and for operators with limited coverage. For these reasons the following technical points should be
considered by service providers operating in a liberated market.
 The geographical stratification and discriminant factors should be examined to ensure that they are
appropriate. For example, addressing characteristics may be highly discriminant if the operation is highly
automated. EN 13850 allows discriminant characteristics to be changed if necessary.
 The types and numbers of customers who can take part in the survey should be examined. If operators
are only offering service to limited numbers of customers, it may be difficult to recruit sufficient panellists,
particularly since the survey requires co-operation from customers.
 The types of induction should be examined. For example, if preferential treatment is offered to certain
classes of customers, then the class of customer becomes an important discriminant characteristic.
 It is important to consider how dates of induction and delivery can be recorded accurately and without
bias. For example, if receivers receive high volumes of real mail each day there may be problems in
intercepting test items. Alternatively if the volume of real mail per poster or receiver is very low, it may
become noticeable to the postal operators that a panellist in the survey is sending or receiving test letters
with a consequent risk of bias to the survey results.
11

---------------------- Page: 12 ----------------------

CEN/TR 14709:2006 (E)
 Information on real mail will be required for geographical stratification and the discriminant characteristics.
In a multiple operator environment real mail information for the total pipeline may be difficult to obtain and
an estimation should be made.
 Operators offering delivery by a specific time should note that the time of day of delivery is not measured
in EN 13850.
 If an operator is accepting mail only under special conditions of posting, it may be more appropriate to
use EN 14534 for bulk mail.
 If operators are using end-to-end track and trace systems it may be more appropriate to obtain quality of
service information from the track and trace systems.
 For cross-border mail, real mail information is required for both posting and delivery countries. In many
cases the operators in the two countries will collect and share information on real mail flows in their own
countries. If shared information is unavailable the operator commissioning the survey will have to collect
information about the flows in both countries.
 If more than one operator is involved in the total operation, information may be obtained similarly as for
cross-border mail by shared information on real mail flows.
 Other ways of collecting real mail information in a multiple operator environment is by using electronic
tags for the whole chain.
Note that in the above, it is assumed throughout that the measurement is carried out end to end from the
customer perspective. This may be the measurement of the end-to-end service provided by:
 an individual operator providing a fully end to end service;
 a group of parallel operators, all providing fully end to end services (parallel operations);
 more than one operator, who, in combination, provide an end to end service, each carrying out only part
of the pipeline (partial pipelines);
 a group of operators, who, in various combinations, provide end to end services, with different operators
carrying out different parts of the pipeline (may include both parallel and partial pipelines).
For an example of the third alternative above, operator A might collect, process, and partially distribute the
mail, whilst operator B and C might further distribute and deliver the mail in different parts of the country.
From the customer’s perspective, they are only interested in the end-to-end service provided. EN 13850
would be suitable to measure this service, but would not in itself be suitable to measure the service provided
within this pipeline by the individual operators.
To measure the transit time for only part of pipeline would require additional information about the handover
point that is not covered in EN 13850. If such measurement is desired, it would be necessary to decide
whether reliable information can be provided (e.g. by the use of electronic tags), or, if not, to consider whether
another standard, such as the bulk mail standard would be more useful.
The results from the quality of service measurement will provide as a minimum a single overall figure for each
provider. When interpreting the quality offered by different providers (see 2.4) it should be borne in mind that
there may be several
