ABSTRACT
Transport
services are one of the most common services in Poland and abroad. Especially
passenger transport is very popular. For those without a car or travelling in
large groups, such transport is a big convenience. On the market there are many
companies that offer this kind of services. Decisions about the particular
service provider shall be based on own experiences of customer, opinions of
others people and quality analysis results which are often available on many different
websites. In such quality analysis special types of methods are used, among
which the Servqual method and its variation the Servperf method should be
mentioned. In the article the Servperf method was used to evaluate the quality
of transport services in the chosen company. In this method the customer does
not evaluate his expectations for the service, but only the final service.
According to the customers of the research company, its services in about 65%
met their expectations. Their also indicated which determinants had the highest
positive and negative impact on the quality of these services.
Keywords: Servperf, transport services, quality
1. INTRODUCTION
On
the market of transport there is big competition. Customers have a choice of
wide range of services such as transport of people or goods, in Poland and
abroad, for individual customers and groups. It is up to the customer what kind
of company he decides to choose. His decision is influenced by many factors
related to the quality of services offered by the company. Transport of
passengers and goods shall be treated as a service, not as a product.
The
service can be defined as a useful immaterial product, which is produced by
human labour (activity) in the production process, by affecting the structure
of a specific object (human or material object) in order to satisfy human needs
(DASZKOWSKA, 1998). The service quality and its analysis is much more complex
problem than the products quality. Evaluation of level of service quality
depends, inter alia on: objective and subjective factors, the level of the
requirements set by a customer, the reference point or mood of the customer
(STOMA, 2012). Therefore, some tools which are used to evaluate the service
quality were created.
One
of the most used tool of the service quality analysis is the Servqual method
(Service Quality). It is used by many different companies, first of all by such
as hotels, banks, hospitals, shops. It was created by Berry, Parasuraman and
Zeithaml (KONSTANCIAK, 2012; INGALDI; JURSOVA, 2013). The Servqual method uses
a multi scale, by means of which it is possible to measure of the service
quality from the point of view of customer, to get many hints associated with
the directions of the quality improvement. This method treats quality as the
difference between customer expectations and actual perceptions of the service.
The analysis of the service quality by the Servqual method begins with
selection of the appropriate set of service quality determinants (KADŁUBEK,
2011).
The
Servperf method (Service Performance) is less known, however, an interesting
method of the service quality analysis. It was created as a contrast proposal
to the Servqual method. The basic assumption the Servperf method is to improve
the service quality. It was created by Cronin and Taylor, who found out that we
cannot examine customer expectations, because the expectations belong to the
ambiguous and variable category. They can change very easily. The Servperf
method, unlike the method Servqual, examines only the level of quality of the
received, realized service (perception), and compares it to the ideal services
(STOMA, 2012). This method gets rid of the subjectivity, because the customer
does not specify in advance its often unreasonable expectations about the
service. The general formula of the method is very easy, which from a practical
point of view makes it easier to apply. The service quality is compared to
customer perception (KUCIŃSKA, 2007; KUCIŃSKA; KOŁOSOWSKI, 2009). This method
is therefore easier to use and less time-consuming compared to the Servqual method
(GILMORE, 2003).
Evaluation
and measurement of the quality service in the Servperf method is based on
determinants derived from the Servqual method. Measurement of the service
quality is made with a seven semantic rating scale (Likert scale), where the
lowest level of the scale is: weak, and the best: excellent – so similar like
in the Servqual method. The better service quality examined by this method is,
the closer the individual scores to the maximum value is (GARCZARCZYK, 2000).
Nowadays,
most people are focused on their continuous movement. They like to spend their
free time far away from home, they want to run their business not only in the
place of work, employers want to send their employees to the conferences,
fairs, exhibitions, social events. For this purpose they use their own cars or
decide to use public or private transport. So they benefit from a wide range of
services offered by different transport companies. On the market there are many
companies which offer such services. It is important that the customer based on
his experiences or experiences of his friends, available information, is able
to choose the offer of high quality.
The
purpose of this article is to evaluate the quality of transport services
offered by one of companies from southern Poland. For this purpose the author
decided to use the Servperf. The analysis allowed to determine what is the
level of services offered by the research company, according to customers and
to provide suggestions for future directions of the company's activities.
Another purpose of the article was to show that the Servperf method is more
objective and easier than the Servqual method.
2. MATERIAL AND METHODS
In
the research presented in this chapter 134 customers of chosen transport
company took part. The research had a form of the Internet survey about which
fulfilment were asked customers after using the services offered by the
research company. Electronic form of the survey provides greater anonymity, and
at the same time facilitates data collection and sorting of results.
The
survey was conducted among customer of one of the transport companies from
Czestochowa. The company offers the transport services of passengers by buses,
minibuses in Poland and European countries. Among the offers a customer can
find daily transport of children and young people to the pool or to the cinema,
school trips, transport of employees, transports of guests to events, transport
of groups to exhibitions, fairs, conferences, social events, tours.
The
proper preparation of the survey is very important element of the research. It
should be remembered that the survey must be written in simple language that
everyone can easily understand, and questions should not be too long, not be
boring for the respondent. Appropriate questions must also provide as much
information about the quality of the test service as possible (LESTYÁNSZKA
ŠKŮRKOVÁ; INGALDI, 2014; DZIUBA; SZOŁTYSEK; KOZYRA, 2011).
In
Table 1 all determinants, which were evaluated during the research, divided
into five basic groups, were presented. In Table 2 the original part of the
original survey about empathy of the staff with its determinants were shown.
The customers were supposed to evaluate every determinant according to the
Liker’s scale presented in this Table. Table 3 includes weights of all
individual groups of determinants (also part of the original survey). The
respondents had to divide 100 points between the individual groups. It can
therefore be noted that the survey itself is very similar to the survey of the
Servqual method, only the part concerning expectations for the service is
omitted.

In
case of each individual determinant, the average evaluation was calculated.
Only these results were presented in the graphical way. Different type of
graphic forms were used. At the beginning with use of the histogram average
values for each determinant were presented, to identify those that got the
highest evaluations. Then with use of the same kind of graphic the comparison
of the average value of individual determinant was compared to ideal evaluation
(percentage fraction to evaluation 7). Then with use of the reversed histograms
wages and average values for each group of determinants were presented. The arithmetic
average and the weighted average for all determinants were calculated and then
they were compared to ideal evaluation. For the calculation of the weighted
average, weights of the individual groups of determinants were used.
3. RESULTS AND DISCUSSION
In
figure 1 the average values of evaluations given by respondents to individual
determinants were presented. While in Figure 2 these value were compared to the
ideal evaluation (evaluation in Liker’s scale).
Figure 1: Aggregated results for the Servperf
method (own
study)
Figure 2: Percentage in relation to the Likert’s
scale for the Servperf method (own study)
From
Figures 1 and 2 it can be concluded that determinant, which received the
highest evaluation from customers, and thus its percentage is closer do ideal
evaluation, was determinant 19, i.e. individual customer treatment. It results
from the fact that it is the transport company that performs specific services
requested by customers.
The
other high evaluated determinants were determinants 14, i.e. well qualified
staff and 20, i.e. provision of services at a time convenient to the customer.
For the customer it is important that the bus driver was suitably qualified and
experienced, and the service is performed, when customers want.
Customers
evaluated the worst promotional materials and Internet website (determinant 4).
In the Internet century well organized website is the key to success of the
company and collection of information for customers. Lack of adequate
promotional material makes that the customers choose different transport
company, which more accurately describes its services and whose information is
easier to find. Another poorly evaluated determinant were smooth and quick work
(determinant 13) and transport fleet (determinant 1). The first determinant can
surprise, since it is smooth and quick work that influences whether or not a
customer will change his mind about ordered services and not go to the
competitors. If it comes to transport fleet, it depends on the income of the company
and its size. Often the customers have very high expectations about the quality
and appearance of the coaches, so later they evaluate them badly.
In
Figure 3 weights of each group of determinant given by respondent were
presented while in Figure 4 average values of each group were shown.
Figure 3: Weights of individual group of
determinants (own study)
Figure 4: Average values of individual group of
determinants (own study)
From
the conducted analysis (Figure 3) it results that the customers most frequently
pointed to the service material infrastructure (average more than 45 points out
of 100). Transport service is very specific, in spite of its immateriality; to
perform it the company needed certain material factors. For the customer
transport fleet, which is used to perform the service, look of staff and
location of the company, are the most important elements for the customers.
In
case of the research transport company the determinant of staff empathy got the
highest average evaluation (Figure 4). Employees of the company treat each
customer individually by offering their services at a convenient time. It
should be noted, however, that this group of the determinants had at the same
time the lowest weight (Figure 3). The service material infrastructure got the
lowest evaluation and at the same time had the highest weight.
The
total average value for all determinants was also calculated. This calculation
was made in two different ways: as an arithmetic average XA and as weighted
average XW.
XA = 4.72
XA = 4.52
On
average, determinants were evaluated at 4.72, after taking into account weights
the average was 4.52 (it was not too much lower than the arithmetic average).
It means that the determinants were evaluated at a level above the average
(over 4 points). Referring both averages to ideal evaluation, it was 67.43% and
64.52%. It means that the transport service offered by the research company on
average approx. 65% meet customer expectations.
4. CONCLUSIONS
The
service quality analysis is very important due to the development of the
service sector in the Polish and world economy, and because of the difficulty
associated with the fact that services have non-material form and it is often
difficult to tell what really is evaluated. The service quality and its
analysis are completely different from the products quality. Therefore, to
analyse the service quality separate research methods, such as Servqual, or its
variant Servperf method were created.
In
the article to evaluate service quality in the chosen transport company the
Servperf method was chosen. It is less popular than the Servqual method, but
according to the literature (STOMA, 2012; GILMORE, 2003) more objective due to
the fact that the customer does not evaluate his expectations for the service,
but only the final service, which may have an impact on the objective research
result.
The
conducted research let show that the customers, who decided for the transport
services of the research company, on average estimated that these services in
about 65% met their expectations. The determinants that had the highest
positive impact on the results were: individual customer treatment, well
qualified staff and provision of services at a time convenient to the customer.
The determinants that had the lowest positive impact on the results were:
promotional materials and Internet website, smooth and quick work and transport
fleet. These determinants should be taken into account by the management of the
research transport company in order to improve the quality of its services.
The
research showed also that the customers pay much attention on service material
infrastructure. This is a group of the determinants which can be seen, touch
and it is easier to evaluate.
The
transport market is very vigorously growing market, where there is a lot of
competition in the form of smaller and larger companies. Therefore, every
company like this should evaluate the quality of its services in order to know
what factors of the services decides if that the customer is satisfied, and
what should be improve.
