USE OF THE SERVPERF METHOD TO EVALUATE SERVICE QUALITY IN THE TRANSPORT COMPANY

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.


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

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.

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.

Staff of the research transport company understands specific expectation of the customers.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.

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).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 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
