[email protected] Abstract Although information resulting from measurement of customer satisfaction (CS) belongs to worthy starters of improvement activities in practice of an organization, they face various barriers which prevent measurement to become systematic. The aim of this study is to research intensity and perception of barriers preventing CS measurement. To achieve the goal, statistic processing of the research results which was done in Slovak republic is used. Totally 435 valid questionnaires were processed and relations among individual barriers of CS measurement were identified and quantified. The results showed that occasional measurement of CS and a lack of personnel are considered to be the biggest ones. Keywords Customer satisfaction measurement; Barriers; Survey. Introduction Impacted by globalization growth and hyper-competition existence, quality management theories started to concentrate on customer satisfaction more widely at the beginning of the 80’s of the 20th century. Customer satisfaction (CS) as a technical term gets gradually into a higher number of industries (marketing, industrial engineering, service management, etc.) and nowadays it belongs to permanent challenges of every organization. There is empirical evidence confirming that CS is a key determinant of organization market success [15]. Positive effects of high CS often become the object of research of several studies in managerial [12], economic [5] or social areas [2]. At present it would be very difficult to disprove the assertion that focusing on CS high level achievement should belong among marginalized areas related to organization effort [12]. A principle of achievement of high CS was integrated to several managerial standardized and open concepts. One of the best known standards which CS presents as one of key strategic goals is ISO 9001: Quality management systems. The standard explicitly and systematically “navigates” an organization through its processes so that also customer requirements aimed at achievement of their high satisfaction are taken into consideration. Also other concepts like EFQM or its modified version CAF present necessity to focus on CS as the most concerned part. To get to know how CS “is created” it is necessary to introduce a wider context of quality management process. In the past, summary approaches to analyse, integrate, manage, and improve customer requirements fulfillment were determined and one of the most universal one was created in the area of Service science. Its authors Parasuraman, Zeithaml, and Berry [10] suggested a model based on GAP principle – i.e. differences between expectations and
16 reality. Later the model was slightly modified getting its universal form and named as quality loop. Measurement of satisfaction SOUGHT QUALITY (requirements) TARGET QUALITY (technical specification of product) DELIVERED QUALITY (degree of fulfillment of technical specification) PERCEIVED QUALITY (degree of fulfillment of requirements) Measurement of performance Customer Provider A B D C 1 2 3 4 Source: Adapted from [4] Fig. 1: Quality loop Quality loop is a graphic representation of quality management process which presents its elements and relations among them (Figure 1). As can be seen there are usually two concerned parties in quality process – a customer and a provider. To achieve acceptable quality degree, at first, an organization has to know customer requirements (part A) and integrate them into product technical specification (B). Designing techniques such as Quality function deployment [6] is most frequently used in case of product quality integration. Consequently, an organization has to ensure the highest possible degree of technical specification fulfillment (C). After the product delivery, customers are confronted with its technical (inherent) and assigned characteristics and perceive the degree of their own requirements fulfillment (D). Determination of conformity rate between expectations (A) and perception (D) is in the quality theory called measurement of customer satisfaction [9]. 1 Aims of Research In spite of provable benefits of CS measurement, there are still various barriers which prevent the process of CS measurement to become a key process of each organization activities validation. Professional and scientific literature introduces several barriers related especially to economic difficulty of satisfaction measurement process [7], although a deeper analysis which would explain the character and the structure of the barriers with reference to a wider context of organization performance is still missing. The aim of the study is to (1) characterize most frequent barriers of CS measurement, (2) get to know their mutual relations better, (3) identify mutual relations between perceived benefit of CS measurement and perceived importance of CS measurement, (4) explore relations between organization results and emphasis on periodicity and systematic nature of CS measurement and (5) identify and characterize groups of organizations having a similar structure of barriers of CS measurement. 2 Methodology To deal with the topic, a standard procedure based on four phases of research was proposed, see Figure 2. During the planning phase professional and scientific sources were reviewed and most frequently mentioned CS measurement barriers were extracted. Apart from the above mentioned barriers the questionnaire contains other variables, e.g. indicators of company perceived success, additional ID attributes or appraisal of opinions related to CS measurement. These additional variables enabled deeper stratification of the results aimed at better understanding of CS measurement barriers structure. After that the questionnaire was
17 made and forms of questions and typology of responses was considered to achieve data of the highest analytical potential. Apart from common scaling in the interval 1 to 5 and 0 to 100, approaches concerning agreement evaluation were used [10], since some of them in specific cases show a more accurate degree of assessment from the point of respondents. When the electronic questionnaire had been processed, a database containing e-mail contacts of organizations operating (performing) in the Slovak Republic was created. Planning Literature (articles, books, reports, web) Input Process Output Content analysis, induction Most frequently barriers to CS measurement Scaling methods (Servqual, scale) Involving information into questionaires Questionaires Free databases of companies Extracting email address Database of contacts Executing Electronical data collection Dataset (database of responses) Interpretation Evaluating Characteristic of barriers of CS measurement Analysis of mutual relations among barriers (bivariate correlation analysis, factor analysis) Information about data analysis, own knowledge Review of benefit-importance relation (K-means cluster) Relation between organisation results and CS measurement importance (Kmeans cluster) Identification of groups of similar organisations (Two-step cluster) Analytical outputs – graphs, tables Literature (articles, books, reports, web) Synthesis Interpretationa and generalization Source: Own Fig. 2: Research design During the realization phase the data were gathered in March and April 2016 and the outputs resulting from the responses – after being checked due to data consistency – were exported to formats enabling execution of common (Excel) and more advanced (IBM SPSS Statistics) statistic procedures. These procedures were executed in the phase of results evaluation and reflected research aims named in the final part of Introduction. Based on the acquired data as well as on information from the planning phase, it was possible to explore 5 main areas systematically. The first one was the characteristic of the main barriers of CS measurement and frequency graphs and stratification according to size and sector of organization. The second area of the research was the analysis of mutual relations among barriers by bivariate correlation analysis and later by factor analysis based on principal component analysis. In the next (the third) area, mutual relation between perception of CS measurement importance and expected benefit which a measurement is to bring was reviewed. To do so, k-means cluster analysis was used and it was interpreted by a scatter-dot chart. The objective of the fourth area
18 was to confirm validity of CS measurement by analysis of relation between the results an organization achieves and importance which organization attaches to the process of CS measurement. The last fifth area was aimed at summary characteristic of similar organizations considering their size, sector and barriers. Analytical outputs in a form of charts and tables were explained during the phase of research interpretation and generalized in discussions and related to the existing knowledge in the area of CS measurement or other wider connections. 3 Results and Discussion Electronic survey aimed at data collection was realized within the Slovak Republic during March and April 2016. Totally approximately 10,000 organizations doing business in various areas were addressed and the number of valid responses was 435. Organizations from 21 economic activities were represented in the number of valid responses (categories were adapted from SR Statistical Office classification). 3.1 Main Barriers of CS Measurement Gathering and evaluation of quantitative and qualitative data has a critical importance for an organization. The structure of data, parameters, indicators or other numerical, graphical or verbal forms of assessment of the past, current, eventually future situation of an organization is usually named a Measurement System. This system is to support decision making based on facts and help an organization to achieve strategic goals [3]. It is neither possible nor reasonable to measure everything and so it is a natural choice of an organization to define what, why and how should be measured. In Figure 3 simple results showing the rate of systematic CS measurement are displayed.

Influenced by increasing number of organization employees also its approach to CS measurement goes up, and majority of medium and large organizations consider their effort in this area as the systematic one. The results also showed that a difference between production and service sector is – from the point of view of ratio between systematic and nonsystematic CS measurement – insignificant. In literature several reasons confirming insufficient attention of organizations to process of CS measurement can be found [11] and the most frequently mentioned are the following ones:
19 Needs of our customer are stable – this is an argument used especially by companies offering commodities, or operating in network-regulated industries or in monopolistic environment to state their low interest in CS measurement. In principle, this statement may not be correct since globalization and development trends accelerate tendencies related to increasing requirements of customers [13]. Lack of personnel – a frequent reason especially in organizations with cumulated functions and a low number of employees [14]. Finance – reasons that CS measurement is costly belong among most frequently presented ones [14]. Occasional measurement of CS – reactive attitude of an organization is behind this reason and the organization uses CS measurement only in a situation when a sudden initiator usually has a negative character emerges (e.g. massive complaints, decline in sales, etc.). In this way organizations use CS measurement as a tool to diagnose the cause of a negative situation [8]. Annoyed customer – organizations are afraid that CS measurement will make customers annoyed and this fact is seen as a barrier to use CS measurement systematically [4]. We do not need to do periodical measurement of CS – a role in systematic implementation of CS measurement is also played by superior conviction of managers that CS measurement does not have to be regular and should have only supportive character [8]. The main adversaries of quality are a lack of interest and a lack of knowledge – the barrier presenting the former one. No benefit – the second adversary of quality is a lack of knowledge. There are several studies pointing out that managers are not often aware of strategic importance of CS measurement [8]. These seven main causes evaluated by organizations which measure CS non-systematically or do not measure it at all became the object of analysis researching the rate of influence of individual barriers of CS measurement. Results in Figure 4 show that the biggest barrier is “Occasional measurement of CS” (average barrier intensity was 62.3 calculated in scale 0 to 100). A finding that organizations are aware of benefits resulting from CS measurement is considered to be positive information and this is proved by relatively low intensity of “No benefit” barrier (average barrier intensity 42.2). An exception is a group of respondents presenting extra-large organizations but since only a very low number of such organizations were involved in the research it is not possible to define any conclusions.

20 Problems related to insufficient capacity of personnel to measure CS (“Lack of personnel”) achieved relatively high level in micro and small organizations. Stratification of the results according to the size brought only relatively consistent results. Stratification of the results according to the sector showed differences between service and production sector. Belief that “needs of our customers are stable” and that CS measurement will make our customers annoyed (“Annoyed customers”) is higher in case of service sector. To verify statistical significance of this difference Two-sample F-test for variances in combination with t-test were used. Statistical procedure based on F-test applying stratification of both mentioned barriers resulted to a partial conclusion that variances of both samples are identical and that Two-sample t-test assuming equal variances is suitable to verify statistical significance. In both cases it confirmed that values tstat are lower than tcrit (in the first case tstat/tcrit results were at the level –1.20/1.98, in the second one –1.65/1.98) and so it is possible to state that a difference between production and services is not statistically significant. 3.2 Relations Among Barriers of CS Measurement To understand internal structure of barriers in customers’ minds better it is appropriate to research their mutual relations (connections, links). For this purpose, approaches based on correlation indexes/coefficients are used most frequently [1]. Best known are correlation and factor analysis. In the first phase relations among individual barriers were examined by bivariate correlation analysis, which presents intensity of mutual dependencies by Pearson correlation coefficient p moving in the interval <–1; 1>. There are results of bivariate correlation analysis in Table 1 that do not show strong explicit relations among investigated barriers. Barriers with p ≤ –0.5 or p ≥ 0.5 are considered as strong ones. Absence of strong explicit relations may not mean that there are no latent relations presented by latent variables among barriers. To research this option factor analysis is applicable too. That is why a data set was subjected to a factor analysis procedure. Tab. 1: Results of bivariate correlation analysis Variable G No benefit F E D C B A Needs of our customers are stable 0.132 0.170 –0.050 0.129 0.058 –0.049 B Lack of personnel 0.096 0.095 0.014 0.072 0.345 C Finance 0.277 0.149 0.161 0.138 D Occasional measurement of CS 0.112 0.326 0.292 E Annoyed customers 0.291 0.317 F We don’t need to do periodical measurement 0.462 Source: Own calculation During examining seven barriers the factor analysis procedure identified, three components (latent variables) in which values lower than 0.2 were hidden (for clarity reason) in Figure 5. Considering the intensity of their relations with barriers they were named as (1) Concerns of consequences, (2) Capacity constraints, and (3) Illusion of status quo. These three components explain in total 62.65% of variables variability. The component “Concerns of consequences” mostly consists of barriers like “Annoyed customers”, “We do not need to do periodical measurement”, “Occasionally measurement of CS” and “No benefit”. It concerns general barriers which result from not knowing benefits and worries of something the effect of which is not seen immediately but after some time. The second identified component was “Capacity constraints” which mostly contains two barriers – “Lack of personnel” and “Finance”. It concerns closely connected barriers which, as the previous analysis proved in Chapter 3.1, are
21 characteristic especially for micro and small organizations. The last identified component was “Illusion of status quo”, i.e. belief that “Needs of our customers are stable”. In a large extent this component consisted only of one barrier of the same name. This in principle not totally appropriate attitude of respondents may result from either self-conviction about perfect market knowledge, organization monopolistic position or simply from not being aware of the growing requirements of customers in market environment. 1: Concerns of consequences 2: Capacity constraints 3: Illusion of status quo Annoyed_customers 0.781 -0.284 We_dont_need_to_do_periodical_ measurement 0.696 0.322 Occasionally_measurement_of_CS 0.609 No_benefit 0.563 0.296 0.318 Lack_of_personel 0.834 Finance 0.223 0.769 Needs_of_our_customers_are_sta ble 0.917 Rotated Component Matrixa Component Extraction Method: Principal Component Analysis.

Source: Own calculation Fig. 5: Identification of latent variables by factor analysis 3.3 Relation Between Perceived Benefit and Attributed Importance of CS Measurement Literature brings a lot of logical and empirical reasons to make organizations pay systematic attention to CS measurement. But how do organizations perceive it? One of the aims of this paper is to clarify it in part. To do so, two individual variables (questions in the questionnaire) were used. The first one was perceived benefit of CS measurement. It may be assumed that organizations will pay more effort to activities bringing demonstrable benefit. The second question was to set the importance of CS measurement. This is not duplicity of the first question since this one helps understand positioning of “measurement of CS” activity in the hierarchy of all organization activities. Respondents could response to both questions in a scale 0–100 and consequently a scatter-dot graph enabled to display mutual configuration of individual cases, see Figure 6. Scattering of individual cases in a two-dimension system was used to enable linear regression (in both cases it has growing character). In case of the production sector a regression curve has a steeper inclination that in the service sector. It means that setting the importance of CS measurement is higher in the production sector. It may be assumed that the reason is one particular feature of services, i.e. a direct contact with the customer/target consumer. Since in case of services this contact is more frequent than in case of production, it may be predicted that customers’ requirements are recorded immediately in the process of services provision and potential corrections in service characteristic might be done relatively quickly. CS measurement might be perceived only as complement to customers´ requirements understanding. But in case of the production the final product is validated after its production has been finished and for an organization CS measurement is a way to identify the degree to which a product meets customers’ requirements.
22 Source: Own calculation Fig. 6: Relation between perceived benefit and importance of CS measurement; service sector (left), production sector (right) Several risks are to be mentioned due to the above mentioned statements. They are related to arguments strength. Relatively low value of R2 (coefficient of determination) which determines how close the data are to the fitted regression should be considered, and so these interpretations should be taken as possible explanation. 3.4 Relation Between Organization Results and Emphasis on CS Measurement Several positive examples confirmed that organizations which pay systematic attention to CS measurement achieve better market results [8]. The research which was a part of this presented one was a very good opportunity to verify the stated results empirically. Since the electronic way of questioning was anonymous, only subjective indicators of organization results were obtained. To prevent problems concerning results comparison, since organizations have different results indicators across sectors and also different ones due to their size, it was decided to use a scale 0–100 to evaluate their own results. The results were evaluated by two variables: success of organisation and market position of an organisation. Responses were divided into two categories, the first one being presented by organizations which pay systematic attention to CS measurement and the second one including organizations which do not measure CS systematically. The results were processed in a form of scatter-dot chart utilizing the principle of cluster analysis, see Figure 7. The coordinate system might be divided into four quadrants. There are unsuccessful organizations with a low market position (power, share) at the left bottom. At the right bottom there are several organizations whose market power is very high but are not considered to be successful – they are supposed to operate in monopolistic environment. On the left top there are usually small organizations with a relatively low market position but considered as rather successful. On the right top there are market leaders from both points of view – their market position and perception of their own success.
23 Source: Own calculation Fig. 7: Achievement of organization results due to periodicity and system in CS measurement; all the organizations (on the left), service sector (in the middle) and production sector (on the right) Individual organizations are represented in the coordinate system by corresponding points distinguished according to the fact whether an organization (1) pays or (2) does not pay systematic attention to CS measurement. Calculation of centroid of these two groups results to average position of organizations. In the coordinate system (x; y) the centroid of organizations paying systematic attention to CS measurement was in the right top quadrant and its coordinates were (56.6; 78.2) and the centroid of organizations which do not measure CS systematically was in the left top quadrant and its coordinates were (45.6; 66.3). Based on this, it may be stated that CS measurement has an impact on organization results particularly on their success (in higher extent) and later also on their market position (in lower extent). Similar conclusions may be induced from data stratification for the service as well as for the production sector, see Figure 7 in the middle and on the right. 3.5 Groups of Similar Organizations The survey which had been performed enabled execution of further statistical procedures clarifying uncertainties concerning causes barriers of CS measurement. Relatively valuable information is the identification of type representatives, i.e. groups of comparatively homogeneous subjects whereby these groups are mutually heterogeneous. For this purpose, it is best to use cluster analysis and in this paper two-step cluster analysis was applied. Five variables entered the procedure of clustering: the size of the organization, sector, concerns of consequences, capacity constraints and illusion of status quo. Last three variables presented an output from factor analysis introduced in Chapter 3.2. The results of this clustering are displayed in Figure 8.
