Servicescape is a model developed by Booms and Bitner to emphasize the impact of the physical environment in which a service process takes place. The aim of the servicescapes model is to explain behavior of people within the service environment with a view to designing environments that accomplish organisational goals in terms of achieving desired behavioural responses. For consumers visiting a service or retail store, the service environment is the first aspect of the service that is perceived by the customer and it is at this stage that consumers are likely to form impressions of the level of service they will receive.
Booms and Bitner defined a servicescape as "the environment in which the service is assembled and in which the seller and customer interact, combined with tangible commodities that facilitate performance or communication of the service". In other words, the servicescape refers to the non-human elements of the environment in which service encounters occur. The servicescape does not include: processes (e.g. methods of payment, billing, cooking, cleaning); external promotions (e.g. advertising, PR, social media, web-sites) or back-of-house (kitchen, cellars, store-rooms, housekeeping, staff change rooms, spaces) where customers do not normally visit.
The servicescape includes the facility's exterior (landscape, exterior design, signage, parking, surrounding environment) and interior (interior design and decor, equipment, signage, layout) and ambient conditions (air quality, temperature and lighting). In addition to its effects on customer's individual behaviors, the servicescape influences the nature and quality of customer and employee interactions, most directly in interpersonal services. Companies design their servicescapes to add an atmosphere that enhances the customer experience and that will affect buyers' behavior during the service encounter.
The servicescapes model is an applied stimulus-response model where the application is specific to the service sector. The model was developed by US academic, Mary Jo Bitner in 1990. It is influenced by a branch of social science known as environmental psychology. In services marketing, the servicescapes model has become the dominant framework for studying and evaluating the physical environment in which service encounters occur. According to Lusch and Vargo, the servicescape is an important resource that enables the firm to "channel consumer realities in certain ways". Empirical studies have demonstrated that the servicescape affects both the customer's emotional and behavioural responses in service settings.
The SOR model (stimulus->organism->response model) describes the way that organisms, including customers and employees, respond to environmental stimuli (e.g. lighting, music, interior-design). In essence, the model proposes that people's responses exhibit three broad types of responses to stimuli in the external environment - physiological, emotional (affective) and behavioural responses.
Environmental psychologists investigate the impact of spatial environments on behaviour. Emotional responses to environmental stimuli fall into three dimensions; pleasure, arousal and dominance. The individual's emotional state is thought to mediate the behavioural response, namely approach or avoidance behaviour towards the environment. Architects and designers can use insights from environmental psychology to design environments that promote desired emotional or behavioural outcomes.
Three emotional responses are suggested in the model. These responses should be understood as a continuum, rather than a discrete emotion, and customers can be visualised as falling anywhere along the continuum as shown in the diagram.
The individual's emotional response mediate the individual's behavioural response of Approach-> Avoidance. Approach refers to the act of physically moving towards something while avoidance interferes with people's ability to interact. In a service environment, approach behaviours might be characterised by a desire to explore an unfamiliar environment, remain in the service environment, interact with the environment and with other persons in the environment and a willingness to perform tasks within that environment. Avoid behaviours are characterised by a desire to leave the establishment, ignore the service environment, and feelings disappointment with the service experience. Environments in which people feel they lack control are unattractive. Customers often understand the concept of approach intuitively when they comment that a particular place "looks inviting" or "gives off good vibes". The desired level of emotional arousal depends on the situation. For example, at a gym arousal might be more important than pleasure (No Pain; No gain). In a leisure setting, pleasure might be more important. If the environment pleases, then the customer will be induced to stay longer and explore all that the service has to offer. Too much arousal, however, can be counter-productive. For instance, a romantic couple might feel out of place in a busy, noisy and cluttered restaurant. Obviously, some level of arousal is necessary as a motivation to buy. The longer a customer stays in an environment, the greater the opportunities to cross-sell a range of service offerings.
Mehrabian and Russell identified two types of environment based on the degree of information processing and stimulation:
Activities or tasks that are low load require a more stimulating environment for optimum performance. If the task to be performed in relatively simple, routine or boring then users benefit from a slightly more stimulating environment. On the other hand, tasks that are complex or difficult may benefit from a low load environment.
The servicescapes model is an applied stimulus-organism-response model (SOR model), which treats the physical environment as the stimulus and the response is the behavior of employees and customers within the physical environment. The servicescape performs four important roles - packaging - presents the outward appearance to the public; facilitator - guides the efficient flow of activities; socialiser - conveys expected roles to both employees and customers and differentiator - serves as a point of difference by signalling which segments of the market are served, positioning the organisation and conveying competitive difference.
The elements of the physical environment itself make up the inputs (stimuli). Environmental inputs are sensory, spatial and symbolic. For convenience, these elements are normally considered as three broad categories including:
Each element in the physical environment serves multiple purposes. For instance, furnishings may serve a functional role in that they provide seating where patrons can wait for friends or simply enjoy a quiet rest, but the construction materials may also serve a symbolic role in which they communicate meaning through shared understandings. Plush fabrics and generous drapery may signify an elegant, up-market venue, while plastic chairs may signify an inexpensive, family-friendly venue. Signage may provide information, but may also serve to assist customers navigate their way through a complex service environment. When evaluating the servicescape, the combined effect of all the elements must also be taken into consideration.
Ambient conditions refer to the controllable, observable stimuli such as air temperature, lighting and noise. Ambient factors, such as music used in servicescapes, have been found to influence consumer behaviors. One study found that "positively valenced music [joyful] will stimulate more thoughts and feeling than negatively valenced [mournful] music ", hence, positively valenced music will make the waiting time feel longer to the customer than negatively valenced music. In a retail store, for example, changing the background music to a quicker tempo may influence the consumer to move through the space at a quicker pace, thereby improving traffic flow. Evidence also suggests that playing music reduces the negative effects of waiting since it serves as a distraction.
According to Zeithaml et al., layout affects how easy or difficult it is to navigate through a system. Two important aspects of layout are functionality and spatial layout. Functionality refers to extent to which the equipment and layout meet the customer's goals while spatial layout refers to how physical elements are arranged, the size of those objects and the spatial arrangements between them.  With respect to functionality of layout, designers consider three key issues; circulation - design for traffic-flow and that encourages customers to traverse the entire store; coordination - design that combines goods and spaces in order to suggest customer needs and convenience - design that arranges items to create a degree of comfort and access for both customers and employees. Spatial layout is closely related to space utilisation. Some research suggests that customers associate more spacious surroundings with higher quality services. 
Signs, symbols and artefacts refer to a broader category of objects that serve multiple purposes. Signs and symbol refer to physical signals that provide cues for directional purposes, provide information about appropriate behaviour within a store or servicescape and may also serve a symbolic role. Some signs perform rudimentary roles such as providing directions for navigation through a space while other more complex signs that communicate through shared meaning systems. Physical environment elements not only serve a functional or utilitarian role, but they communicate meaning in very subtle ways through symbolism. In an office environment, a big desk can symbolise the manager's power, and this can have the potential to make those who sit on the opposite side of the desk feel less relaxed and less willing to speak out.  The use of colour also communicates at a symbolic level in ways that impact on behaviour. 
Artefacts refer to objects that hold some type of cultural, historical or social interest for customers. They are the tangible reminders of the service experienced by consumers. Artefacts may be purpose-designed objects that serve as souvenirs or mementoes of a pleasant experience. Many services, such as museums, galleries, theatres and tourist attractions, manufacture artefeacts that form the basis of a merchandise collection, available for sale to visitors and guests. These artefacts, more commonly known as souvenirs, can often be retailed at prices well above market value because of the memory consumers attach to the experiential encounter. 
When consumers enter a servicescape, they process multiple stimuli almost simultaneously. Consumers scan the ambient conditions, layout, furnishings and artefacts and aggregate them to derive an overall impression of the environment. In other words, the holistic environment is the cumulative effect of multiple stimuli, most of which are processed within a split second. These types of global judgments represent the summation of processing multiple stimuli to form a single impression. In the servicescapes model, this type of impression is known as the holistic environment.
Through careful design of the physical environment and ambient conditions, managers are able to communicate the service firm's values and positioning. Ideally, the physical environment will be designed to achieve desired behavioural outcomes. Clever use of space can be used to encourage patrons to stay longer since longer stays result in more opportunities to sell services. At other times, the ambient conditions can be manipulated to encourage avoidance behaviour. For example, at the end of a busy night of trading, a bar manager might turn the air conditioning up, turn up the lights, turn off the background music and start stacking chairs on top of tables. These actions send a signal to patrons that it is closing time.
The organism dimension refers to the two groups of people that make up the service encounter - customers and employees. Both groups inhabit the same physical environment, yet their perceptions of it may vary because each comes to the space for different reasons. For example, a waiter in a restaurant is likely to be pleased to see a crowded dining room because more customers means more tips. Customers, on the other hand, might be less pleased with a crowded space because the noise and queues have the potential to diminish the service experience.
A moderator is any variable with the potential to change the relationship between a dependent and independent variable. Moderating variables describe what effects will hold in certain conditions. A mediator is an intervening variable that helps to explain the relationship between two variables.
In the servicescape model, a moderator is anything that increases the standard stimulus-response states of pleasure-displeasure, arousal-non-arousal or dominance-submissiveness while the response behaviour is mediated by internal responses including the cognitive, emotional and physiological responses. The consumer's response to an environment depends, at least in part, on situational factors such as the purpose or reason for being in the environment. For instance, a consumer who walks into a slightly chilly room, may shiver and feel a little uncomfortable. Faced with such a situation, the consumer may respond in various ways - some consumers will choose to add another layer of clothing, others will leave the environment as soon as practical, while yet others may simply endure the minor discomfort. If the consumer has a strong motivation for being in the environment, he or she is more likely to suffer the minor inconvenience of an uncomfortable ambient temperature. Thus, the consumer's motivation or reason for being in the servicescape mediates the ultimate behavioural response.
The model shows that there are different types of response - individual response (approach and avoid) and interaction responses (e.g.social interactions).
In the context of servicescapes, approach has a special meaning. It refers to how customers utilize the space, during and after the service encounter. Approach behaviours demonstrated during the encounter include:
Approach behaviours demonstrated at the conclusion of the encounter or after the encounter include:
Avoid behaviours are characterised by a desire to leave the establishment, ignore the service environment, and feelings disappointment with the service experience.
Bitner's pioneering work on servicescapes identified two broad types of service environment:
According to the model's developer, the servicescape acts like a "product's package" - by communicating a total image to customers and providing information about how to use the service.
