A holistic approach to manage environmental quality by using the Kano model and social cognitive theory

and key words of the scientific articles. These search key words included “Kano model” paired with “city,” “climate,” “indoor,” “emissions,” “environment,” “environmental,” “environmental and quality,” “environmental services,” “environmental products,” “environmental quality,” “life cycle assessment,” “pollution,” “recreation areas,” “transport,” “urban,” “waste,” and “water.” The reference list of the obtained documents also was looked up to further documents. The search protocol was executed on August 20, 2018, and in total, 119 documents were found that meet the defined search key words. Next, these articles were reviewed based on the content of titles and abstracts, by excluding 74 and 15 studies accordingly. There was a relatively large number of articles excluded by title because the Kano model has been used also in various studies targeting information technologies and linked services, as well as healthcare services and teaching practices, and Kano is also a state located in Nigeria. Later exclusion by title mostly was dealing with sorting out Kano application to industrial technologies, products, and services not linked with the scope of this study (environmental services). Finally, 27 documents were selected for inclusion in this paper (see Figure 4). FIGURE 4 The identification process of articles included in this paper FIGURE 5 Number of publications per year published on the applicatio study by Finster et al. (2001) 5 | THE KANO MODEL IN ASSESSING ENVIRONMENTAL QUALITY: EVIDENCE OF APPLICATION At the beginning of these millennia, Finster et al. (2001) published a study where authors state that the Kano model expands “the toolbox of the industrial ecologist and enables the link between green design and business improvement,” as it makes visible the customers' perceptions of the critical environmental attributes. In the study, Finster et al. (2001) introduce several environment‐related concepts (including environmental product attribute), treat the environment as a customer segment, and demonstrate how efficient the Kano model is in revealing design opportunities and attributes of product or service that consider environmental issues. Finally, authors expand the Kano model to link the environmental attributes to business incentives and strategy, as the business value of the attributes becomes visible. Nevertheless, since Finster et al. (2001) published the study, only a limited number of other works have been published where the Kano model is applied for the assessment of environmental quality (see Figure 5). Thus, one of the main motivations of this study was to present all possible applications of the Kano model for environmental quality management. Two distinct areas of the application can be identified: urban environmental quality and indoor environmental quality. We find the reason for that may lay in the definition of environmental quality. Johnson et al. (1997) define environmental quality as a measure between the actual environmental condition and optimal conditions for a specific species in a special habitat. With respect to this definition, the application of the Kano model in assessing environmental quality mostly focuses on consumers (residents) and their environments. Thus, we presented various case studies from these domains so that these all divergent applications can be found in one review article and the reader can see the vast application possibilities of this tool. The contribution of the Kano model to the studies on the quality of the urban environment is onwards discussed. Yin, Cao, Huang, and Cao (2016) used the Kano model integrated with the importance– n of the Kano model for environmental quality assessment since the

. Yet there are also some "untraditional" applications, for example, in the assessment of urban soundscape (Jennings & Cain, 2013).
The aim of the research is to review how the Kano model has been used for assessing environmental quality and perception of environmental quality by consumers so far and next, to discuss the extension of the application of the Kano model with the concept of social cognitive theory-Bandura's triangle. This extended Kano-Bandura's model could create products and services that trigger sustainable social behavior and promote environmental quality.
Environmental quality is defined as "a measure of environmental condition relative to the requirements of one or more species or to any human need or purpose" (Johnson et al., 1997). In other words, it is a set of environmental aspects that affect organisms in their natural environment, such as air quality, surface water quality, drinking water quality, soil fertility, domestic and industrial pollution, overpopulation, and noise. Yet another, more sophisticated, meaning deals with the perceived environment, that is, the material and immaterial qualities (attributes) of man-made built and natural environment that support social and cultural structures of a specific group of people and hence provide them satisfaction with the physical settings. Additionally, products and services provided and used within these physical settings play a significant role as they may have a positive or negative effect on the experience of the perception. For example, installation of a water treatment system may significantly improve the perception of an area with otherwise poor water quality. Also, the industry recognizes the need for developing sustainable products as these products are perceived by end user as of higher value (Dace, Bazbauers, Berzina, & Davidsen, 2014). The specific attributes of environmental quality represent the preferences of an individual or a group of people. Thus, understanding these preferences is important for designing products and services that shape environmental quality.
We believe the Kano model might serve as a valuable tool in converging products and services towards sustainable social behavior.
And vice versa, individual and social behavior can be directed towards sustainability by developing physical settings, products, and services that achieve specific criteria of perceived environmental quality, hence people satisfaction with their environment.
In this paper, we discuss the methodology of the Kano model in Section 2 and the model's advantages and disadvantages in Section 3.
Then in Section 4, we construct a search algorithm, and in Sections 5 and 6, we analyze the reviewed studies where attributes of environmental quality have been assessed by using the Kano model alone or integrated with other tools. Here, Section 5 discusses the use of exclusively the Kano model for various environmental quality management issues. Next, we also wanted to have a separate section that describes only emerging use of the Kano model together with other tools; therefore, we divided Sections 5 and 6 into two separate parts. Finally, in Section 7, we look at how the Kano model can be extended with Bandura's triangle to create products and services that trigger sustainable social behavior and promote environmental quality. Section 7 is based on our expertise and knowledge, where we extended current understanding about the Kano model and the use of the Kano model by proposing to link this model with social behavior tools. Section 7 is our addition to current scientific knowledge of such tools.

| BACKGROUND OF THE KANO MODEL
The theory of attractive quality proposes a methodology for describing the relationship between an objective aspect (as physical sufficiency) and a subjective aspect (as customer satisfaction; Kano, 2001). As a result, the relationship or the attributes are translated into five categories of perceived quality: attractive quality (A), must-be quality (M), one-dimensional quality (O), reverse quality (R), and indifferent quality (I; see Figure 1; Löfgren et al., 2011).
The categories of perceived quality are based on two feelings of customers, namely, a feeling experienced when a product has the attribute and a feeling when a product does not have the attribute (Finster, Eagan, & Hussey, 2001), resulting as satisfaction, dissatisfaction, or indifference. The relationship between various quality attributes is nonlinear. In addition, attributes are dynamic-the perception of an attribute by customers will change over time. The attribute can change, for example, from being satisfier (being exciting) to dissatisfier (being expected by default), because once introduced, this attribute initially being exciting will soon be imitated by competitors and expected by customers from every provider (Kano, 2001;Min, Yun, & Geum, 2018;Shahin & Zairi, 2009; see Figure 2). For example, after touchscreen was introduced to a phone by Apple Inc., it was expected in all other smartphones ever followed.
Finally, the Kano model includes a step-by-step methodology that can be used by company managers, city developers, organizations, and so forth to understand and classify various quality attributes of their products and services (Löfgren et al., 2011). The methodology uses a structured questionnaire that consists of pairs of questions for each attribute of the specific product or service. In each pair, the first question asks how a customer would feel if an attribute is present or fulfilled (functional question; see Figure 3 under survey questions), whereas the second question asks about the customer's feelings in the case of absence or nonfulfillment of the attribute (dysfunctional question). Further, the data are analyzed using an evaluation table (see  (Mikulic & Prebežac, 2011). For company managers or researchers, a comprehensive step-by-step guide, sometimes with ready-to- use   FIGURE 1 The concept of the theory of attractive quality spreadsheet tools, is provided by several websites (e.g., see Moorman, 2012;Zacarias, 2015).
When two attributes cannot be provided simultaneously due to technical or economic reasons, the attribute with the highest impact on customers' satisfaction should be offered (Chen & Chuang, 2008). Yet the Kano model not only provides valuable guidance in trade-off situations (Conklin, Powaga, & Lipovetsky, 2004) but also serves as a tool for product design and development as such. The Kano model allows designers to identify the attributes that are expected (mustbe) to be included in the product design, the attributes that place the designed product superior to competitors' products (attractive), and the attributes that would be of no value (indifferent) to customers.
When met, the categories of perceived quality influence customers' satisfaction in different ways and are explained as follows: 1. The must-be or basic quality-attributes of this category are taken for granted, not explicitly demanded, yet their fulfillment does not lead to customer satisfaction. In fact, customers' satisfaction does not rise above neutral, just lead to a state of "not dissatisfied." Nevertheless, must-be attributes are a decisive competitive factor. Customers become dissatisfied if the product attributes of this category are missing or their performance is low and will not be interested in the product at all (Bilgili, Erci, & Ünal, 2011;Chen & Chuang, 2008;Sauerwein, Bailom, Matzler, & Hinterhuber, 1996).
2. One-dimensional or performance quality-customer satisfaction is a linear function of the fulfillment of the product attribute, that is, the higher is the performance of the attribute, the more satisfied a customer becomes and vice versa. Usually, the one-dimensional
4. The indifferent quality-the attributes towards which customers feel indifferent. Fulfillment or absence of these attributes has no effect on customers' satisfaction or dissatisfaction (Chen & Chuang, 2008;Paraschivescu & Cotîrle, 2012).
6. The questionable quality is the one that cannot be mapped because any level of its performance can lead to the customers' satisfaction or dissatisfaction (Min et al., 2018). The original Kano model was used for more than 20 years until its first refinement was published (Gregory & Parsa, 2013). Löfgren and Witell (2008), Mikulic andPrebežac (2011), Shahin, Pourhamidi, Antony, andPark (2013), and Song (2018) can be consulted for systematic and critical reviews of development and modifications of the Kano model.

| ADVANTAGES AND DISADVANTAGES OF THE KANO MODEL
Application of the Kano model in categorizing the quality by perceived customers has several advantages. First, priorities for product or service development can be defined. For example, improving onedimensional or attractive attributes might influence the customer's satisfaction more than investing in must-be attributes that already are at a satisfactory level (Sauerwein et al., 1996). Second, the product requirements can be understood better-attributes having the greatest influence on customers' satisfaction can be identified. After classifying the product requirements into categories of perceived quality, the focus for product development can be formed (Bilgili et al., 2011). In addition, no technical limitations regarding the number of attributes to be analyzed exist (Mikulic & Prebežac, 2011). Also, the Kano model provides useful assistance in trade-off situations, when two attributes cannot be provided simultaneously due to technical or economic reasons (Conklin et al., 2004). The Kano model creates possibilities for placing one product among other products in the market. A product that meets only the must-be and one-dimensional quality requirements is perceived as an average and hence interchangeable with other products in the market (Bilgili et al., 2011). Finally, the Kano model demonstrates high flexibility of integrating it with other tools, models, and approaches, quality function deployment being the most utilized (Ek & Çıkış, 2015;Ginting, Hidayati, & Siregar, 2018).
In product development, identifying customer needs, their priorities, and hierarchy is a prerequisite (Griffin & Hauser, 1993). Yet the Kano model has also been criticized for the model's inability to categorize product attributes without quantifying the attributes' numerical or qualitative performance (Gregory & Parsa, 2013). The review by Bi (2012) on the methods for analyzing consumers' satisfaction points out that the Kano model does not give the relative importance of the attributes falling in the same category. Therefore, other techniques, such as treebased or recursive partitioning models that are generally referred to as data mining, statistical, and machine learning, are advised. Particularly for the research on consumers' satisfaction Bi (2012) suggests the use of Random Forest, variable transformation, and Lindeman, Merenda and Gold's (LMG measure) methods. The Kano model is also criticized for the weighting methods used; thus, the work by Lee, Sheu, and Tsou (2008) proposed the combination of the Kano and fuzzy models to remove any discretions from surveys. Meanwhile, Song (2018)  These studies indicate that not only identification of the attributes is important but also the context in which these attributes are used. Also, the characteristics of the consumers are essential to translate these identified attributes into sustainable products that satisfy customers.

| SEARCH PROTOCOL
In the following sections, we explore the cases where the Kano model has been used for the assessment of environmental quality.
The aim of the literature review was to systematically analyze the current use of the Kano model for various environmental quality aspects, such as indoor climate, transport, waste management, and water use. In this study, quantitative content analysis was used to assess scientific articles and then to combine them under similar themes (Riffe, Stephen, & Frederick, 2014).
The literature search was done in the Elsevier Scopus database because it is the largest abstract and citation database of peer-reviewed scientific journals, conference proceedings, and books (Elsevier, 2018).
Predefined key words were used for search in the fields of title, abstract, and key words of the scientific articles. These search key words included "Kano model" paired with "city," "climate," "indoor," "emissions," "environment," "environmental," "environmental and quality," "environmental services," "environmental products," "environmental quality," "life cycle assessment," "pollution," "recreation areas," "transport," "urban," "waste," and "water." The reference list of the obtained documents also was looked up to further documents.
The search protocol was executed on August 20, 2018, and in total, 119 documents were found that meet the defined search key words. Next, these articles were reviewed based on the content of titles and abstracts, by excluding 74 and 15 studies accordingly. There was a relatively large number of articles excluded by title because the Kano model has been used also in various studies targeting information technologies and linked services, as well as healthcare services and teaching practices, and Kano is also a state located in Nigeria.
Later exclusion by title mostly was dealing with sorting out Kano application to industrial technologies, products, and services not linked with the scope of this study (environmental services). Finally, 27 documents were selected for inclusion in this paper (see Figure 4).

| THE KANO MODEL IN ASSESSING ENVIRONMENTAL QUALITY: EVIDENCE OF APPLICATION
At the beginning of these millennia, Finster et al. (2001)  planning. Authors emphasize that investments are often made in the attributes where the residents do not perceive improvements due to the nonlinear relationship between various attributes in the city and residents' perception of these attributes. Llinares et al.'s (2013) research shows that the Kano model provides an effective way for categorizing users' requirements and helps to understand the nature of these requirements considering nonlinearity of users' behavior.
Thus, urban planning is achieved in a more resource-efficient and effective way. The above-reviewed studies all demonstrate the application of the Kano model for promoting the satisfaction of urban residents with environmental quality by identifying and prioritizing various aspects and attributes of products and services in an urban setting.
Another group of the studies using the Kano model is for the assessment and management of the quality in an indoor environment.
The application in this field of research is much wider; this article will only give the references to some of the most relevant research in this field by guiding the reader to further explore these resources. The study by Kim and de Dear (2012a) used the Kano model to compare the perceived performance of 15 specific factors of indoor environment quality (e.g., temperature, air quality, and noise level) on occupants' overall satisfaction and productivity and specifically occupants' satisfaction in buildings that have different ventilation systems (Kim & De Dear, 2012b). The review by Shafaghat et al. (2016) for indoor environment quality focuses on the methods and models to determine users' satisfaction in buildings. Authors of the review conclude that and temperature) and correlated these self-reported parameters with measured data on solar irradiation, outdoor temperature, and relative humidity. Authors found the causal links between the weather conditions outside and the comfort level of building's occupants inside.
Also, in the study by Geng, Yu, Lin, Wang, and Huang (2017) on passengers' satisfaction at an airport, the authors found that the reported satisfaction levels correlated well with the measured indicators of indoor environmental quality, such as CO 2 concentration, illuminance, and noise level. A similar conclusion was found by Martellotta, Simone, Della Crociata, and D'Alba (2016) where both surveys and measurements of indoor environment quality in supermarkets were investigated for 2 years. Here, again self-reported data correlated with measurements, yet the authors of this particular study used not only correlation analysis but also the factor analysis and nonlinear methods based on the Kano model. The study found that all workers in supermarkets can be divided into two groups: (a) workers that were more concerned with visual and acoustic comfort at work and (b) workers concerned with thermal comfort. By separating these two data sets, more precise models for the management of indoor environment can be obtained. A similar study has been carried out in hospitals by Vieira et al. (2016) by pairing the Kano and multinomial models. Luor, Lu, Yu, and Lu (2015) studied the quality of the indoor environment in a much broader sense by developing the Kano model for the satisfaction of users living in smart houses. Authors found that entertainment, security, and automation correlated with perceived usefulness. These studies on indoor environmental quality indicate that the Kano model is an objective tool suitable for identifying various attributes of environmental quality, especially when coupled with other, instrumental, tools. We further identify and review studies where the application of the Kano model has been extended to integrating it with the tools used in the environmental quality assessment.

| INTEGRATION OF THE KANO MODEL WITH ENVIRONMENTAL ASSESSMENT TOOLS
The assessment of environmental quality encompasses tools and methods to converge towards optimal environmental conditions. perception of environmental quality that is a significant aspect in reaching efficient and sustainable use of resources.

| THE RELATIONSHIP BETWEEN THE ATTRIBUTES OF ENVIRONMENTAL QUALITY AND SOCIAL BEHAVIOR
Human behavior and environmental quality have been studied interconnectedly using various approaches rooted in the field of environmental psychology. Some of them are the norm activation model (Schwartz, 1977), the theory of reasoned action (Ajzen & Fishbein, 1980), social cognitive theory (Bandura, 1986), and planned behavior (Ajzen, 1991), value-belief model (Stern, Dietz, Abel, Guagnano, & Kalof, 1999), attitude-behavior-context model (Stern, 2000), and goal-framing theory (Lindenberg & Steg, 2007). The research in human interaction with the environment is studied in a couple of major perspectives. For instance, research is done to foster the behavioral change of consumers to save energy and/or natural resources. For example, Perlaviciute and Steg (2015) studied the choice of energy alternatives based on the value system of consumers; Vīgants, Blumberga, Timma, Ījabs, and Blumberga (2016)  In this study, we further employ the social cognitive theory, as it helps explain how personal, behavioral, and environmental factors are intertwined and continuously affect each other. This triadic reciprocal determinism unfolds multiple angles for studying behavioral change, including environmental and personal change. Human behavior alters environmental conditions and, in turn, is changed by the same conditions that it creates (Bandura, 2009). Similarly, both environmental and behavioral factors constantly influence human attitude, that is, perceptions of the involved people, and vice versa. Behavior represents the actions of a person as the actual response to the current situation. An environment is an aspect that surrounds the person belonging to both physical and social environments. A person represents the types of beliefs, attitudes, and skills the person assigns to the current situation.
The social cognitive theory is instantiated by the attitude-behavior-environment (ABE) triangle (see Figure 6), which is very instrumental to better understand and explain phenomena laying on the intersection of human nature and its surrounding environments. Similar to the Kano model, the social cognitive theory has been applied to help design technology aimed at intentionally affecting human attitude and behavior. For example, the ABE triangle was used by Stibe, Röderer, Reisinger, and Nyström (2019) to study the perspective of positive long-term changes in lives and businesses that are being unified under the transforming well-being theory. Previously, the ABE triangle has been applied to help designing technology aimed at intentionally affecting human attitude and behavior. For instance, Stibe (2014Stibe ( , 2015 has demonstrated how the ABE triangle can foster the designing of engaging environments using socially influencing systems, aimed at user involvement and participation. Further, Stibe and Larson (2016) have expanded this perspective by looking at environmental influencers in cities, thus addressing and reviewing possible urban designs and technology-supported spaces for behavioral and attitudinal changes at scale. Overall, the ABE triangle helps to articulate the perspective of positive long-term changes in lives and businesses that are being unified under the theory of transforming well-being (Stibe et al., 2019).
We see that the Kano model (given in gray color in Figure 6) can be integrated with the social cognitive theory (given in black color in Figure 6) because of the context of environmental quality and related human dynamic that mainly manifests itself through attitudes and behaviors of people. When discussing environmental attributes and their effects on people and their satisfaction towards various levels of quality, it is inevitable to have human behavior and attitude as a coherent part in the holistic picture of this discourse. Obviously, the environment around us and its quality are strongly determined by what kind of footprints people leave in it. Certainly, the impact on the environment most commonly starts with something that people initially think of doing (attitude) and then making it happen (behavior).
Such interconnectivity is essentially highlighted by the social cognitive theory. Meanwhile, the ABE triangle explains the dynamic between the attitude, behavior, and environment. Thus, the theory and triangle serve as the next essential layer that helps to position and explaining how the Kano model can be further meaningfully applied to the context of environmental quality and related social behavior. The Kano model is a tool that helps to measure the three elements of the social cognitive theory, whereas social cognitive theory can use these measures to study how the three elements affect each other. Moreover, the triangle helps to integrate the Kano model into a broader perspective that enables seeing it dynamically connected to its surroundings in this applied research context, thus empowering its evolvement in a sustainable manner.
The Kano model together with social cognitive theory portrays that well-considered and assessed quality attributes can drive positive individual and social behavior that have a substantial effect on facilitating personal well-being and environmental sustainability.
Installation of bicycle paths in a city serves as a trivial examplewell-designed infrastructure encourages daily cycling that improves both personal and environmental health. If the technology aimed at promoting the bicycling is added as well, in this case, attitude and behavior can be affected even more. For example, publicly available boards showing instant information on the number of other cyclists may impact an individual to consider cycling, as demonstrated by Hofmeister and Stibe (2017) and Millonig et al. (2016). In addition, social behavior may serve as an indicator of the potential improvements in environmental quality. For example, littering on streets indicates the need for waste collection and management solutions, yet, by assessing the consumer value, the Kano model can identify the specific solutions that will be the most efficient, hence where investments will be used most efficiently.
Moreover, integration of value-based environmental management into an enterprise shows the creation of long-term enterprise value and aid to the resilience of this enterprise to various social and environmental shocks (Figge, 2005). As given by Muñoz-Torres, Fernández-Izquierdo, Rivera-Lirio, and Escrig-Olmedo (2019), currently, agencies that use environmental, social, and governance rating for enterprises usually identify short-term environmental performance from the perspective of the firm's internal organization and social aspects based on the firm's external judgment, and new tools are needed to account for these all factors in a holistic manner. Finally, Pipatprapa, Huang, and Huang (2017) emphasize that an enterprise manager has to understand the social requirement of concern for environmental protection; hence, tools to assist managers' decision making on environmental evaluation and social aspects are needed.
On the basis of the reviewed articles, we propose to link environmental quality and social behavior into a single model (see Figure 7).
The study by Xu, Wu, and Jing (2017)   perception of an attribute, especially considering the dynamic change of perceiving an attribute over time (see Section 2). For example, a recreation area nearby may be perceived as an attractive attribute by a customer that has not previously experienced such conditions, whereas the same conditions might be a must-be attribute to a customer that has had the nearby located recreation area before. Finally, the perceived environmental quality attributes are evaluated against an internal set of values of an individual or society, as, for example, social norms. Customers are satisfied with an environment, when it supports their requirements (needs and wants), that is, when an environment meets certain quality criteria or preference system of an individual or society. The preference system, in its turn, is affected by a number of factors-cultural, socioeconomic, demographic, geographical, and so forth. Thus, an individual or society has its own components representing the preferred image of satisfying environmental quality.
The level of satisfaction with the environment forms an intention that has an effect on the action performed in and towards the environment. The action performed, in turn, affects the actual environmental quality, thus closing the loop, that is, the attributes of an environment (resulting in environmental quality) affect the individual and social behavior in that same environment. Defining the level of satisfaction with environmental quality is the field of research of the Kano model. Figure 7 is tied to the findings of environmental psychology.

The relationship shown in
We conclude that integration of the Kano model and social cognitive theory may serve as an instrument for designing an environment that not only is perceived as of high quality but also changes customers' attitude and behavior. This framework can be useful for scientists that study systems' interrelationships, such as natural environment, social behavior, and norms, but at the same time would like to base this holistic model on the data based on consumers' feelings and satisfaction. This framework can be used for studying a wide range of environmental products and services.  The relationship between environmental quality and social behavior simply has not gained sufficient popularity due to aforementioned reasons. In addition, the Kano model is rarely used as a seldom method. In most studies, it is integrated with some other method, quality function deployment, and importance-performance analysis being the most utilized. Still, the Kano model has been useful in studies where understanding the change over time of the customers' perception is important.
Finally, the Kano model rarely helps to gain clear answers to which specific attributes are most significant in achieving the customers' satisfaction. The method does not allow understanding how much the specific attribute contributes to the overall value of the design or plan.
Thereof, it has limitations with respect to ranking the worth of environmental quality attributes. Moreover, monetizing environmental quality is a challenging discipline by itself.
Although the Kano model has several limitations, it can provide valuable insights in environmental quality problems, especially when applied in a well-designed and contextual manner. Considering the findings of the studies reviewed, it can be concluded that the Kano model has a high potential and a relevant methodology for application in the assessment of environmental quality. The Kano model is suitable both for screening type of research, where the main aim is to identify the major factors, for example, influencing comfort levels of residents, and for optimization type of research, where survey results are paired with measurements to determine optimal environmental conditions. In addition, the potential range of the application in assessing environmental quality attributes is wide despite that the current application and range evidenced in studies are limited to urban and indoor environmental quality. Finally, the Kano model is also instrumental for researchers and practitioners in designing and deploying innovations aimed at sustainable social behavior and transforming well-being. In this paper, we have identified the potential integration of the Kano model and social cognitive theory (Bandura's triangle) for driving change of the customers' attitude and behavior via changing the perception of environmental quality. In the future studies, practical implementation and validation of the integrated model are suggested to test its applicability and efficiency.
