The Role of Knowledge Management Infrastructure in Enhancing Job Satisfaction at Aqaba Five Star Hotels in Jordan

The aim of this research is to explore the role of Knowledge Management (KM) infrastructure (organizational culture, organizational structure and information technology) in enhancing job satisfaction at Aqaba five star hotels located in Jordan. A total of 216 questionnaires containing 33 items were used to collect information from the respondents. Multiple regression analysis was conducted to test the research hypotheses. Results of the current study revealed that there is a significant positive impact of KM infrastructure on job satisfaction and these results are in line with the results of the previous studies mentioned in the literature, and also revealed that the dimensions of KM infrastructure that has the highest effect on job satisfaction are organizational culture followed by information technology; whereas the variable of organizational structure has not significant impact on it. Results of T-test showed that there is no significant difference in the impact of KM infrastructure towards job satisfaction in favor of gender. In addition, results of ANOVA test found that there are significant differences in the impact of KM infrastructure on job satisfaction that can be attributed to age, educational level, and personal income.

tacit knowledge [13]. Explicit knowledge refers to knowledge which can be transmitted in the form of formal and systematic languages [17]. It relates to what can be captured and shared through information technology [7]. Explicit knowledge is considered an important management tool that can be used in the manipulation of organizational knowledge. Such knowledge, usually exists in words, pictures, diagrams, computer codes, procedure manuals, and the like, that can be communicated to others in ways that are seen as formal and obvious [18]. Tacit knowledge refers to unarticulated knowledge that exists in the minds of people and is difficult to describe and transfer [16]. [19], (p. 167) defined tacit knowledge as "personal knowledge based on individual experience and influenced by perceptions and values". Researchers have reported that tacit knowledge includes lessons learned, know-how, judgments, rule of thumb, intuition [20], individual experience, skills, beliefs, values, and creative processes [14]. According to the literature, tacit knowledge is an important organizational resource as 42 percent of corporate knowledge resides in the minds of employees and that the successful accomplishment of tasks depends on tacit knowledge [16]. In order to improve organizational performance and create value, organizations should manage both tacit and explicit knowledge since they are mutually dependent on one another and reinforce each others' qualities [14]. Here, systematic and specific processes are used to acquire, organize, sustain, apply, share and renew both tacit and explicit knowledge [21] as tacit knowledge can be of vital importance to organizations when it is converted into explicit form and shared with others [22].
Knowledge management as a whole is considered much more complex in meaning than the terms management and knowledge alone [13]. Knowledge management can be defined as a formal, directed process of determining which information would benefit the company better, compared to others, and finding ways to make information readily available to those that need it [16]. [23] saw knowledge management as a way of creating, executing, transforming, and storing of the right knowledge that leads to the design of better policy, modification of action, and delivery of results. [24] referred to knowledge management as a set of procedures, infrastructures, technical and managerial tools used to create, share, and leverage knowledge within and around the organization.
After a review of the literature, it can be noted that researchers and practitioners have defined knowledge management in terms of three trends: 1) work processes and activities where knowledge management comprises processes, systems, procedures, and instruments that support the identification, capturing, and leveraging of knowledge [25] [26]; 2) Technology infrastructure, which refers to the investment in information to codify, store, share, and disseminate specific types of knowledge beyond physical and time barriers in an easier and less expensive manner than done before [14]; 3) Behavioral norms and practices (Organizational culture) which reflects "a set of valid knowledge, created and shared by a group of people, to solve problems they face in their environment" [27] (p. 5).
The importance of knowledge management for organizations has been reported by many researchers over the years. [15] and [28] for example, suggested that knowledge management creates new capabilities for organizations, enables superior performance, encourages innovation, and enhances customer value. [29] supported this by stating that knowledge management stimulates innovation, improves services provided to customers, and helps organizations achieve business excellence by accumulating, improving the availability and accessibility, and effective use of knowledge. [14] also reported that managing knowledge well assists organizations in becoming flexible, responding quickly to changing conditions, becoming innovative, and improving decision making capacity and productivity. However, in order for knowledge management to be efficient and effective certain capabilities are required. [30] argued that resource-based capability consisting of technology, structure, and culture, in addition to knowledge-based capability, including expertise, learning and information, are needed for organizations to effectively and efficiently manage knowledge. In this study, the resource-based capabilities, also known as knowledge management infrastructure [31], will be investigated further as an important component of knowledge management.
The rest of this paper is organized as follows. It begins with the theoretical framework and previous studies about knowledge management infrastructure, as well as other previous studies links knowledge management infrastructure with job satisfaction.
Then, the methodology in which the research theoretical model, hypotheses, population and sample, data collection and analysis methods, and the validity and reliability of the study are presented. It then provides the results and explanations which show the results of the data analysis of the research hypotheses and explanation of these results.
The discussion and conclusion are then provided and areas for future research are also addressed.

Knowledge Management Infrastructure
Knowledge management infrastructure capability refers to modular products and organizational designs that encourage knowledge management activities in an organization [32]. KM infrastructure can be classified into two major capabilities, technical and social infrastructure. Technical infrastructure includes physical, IT infrastructure, devices and components. Social infrastructure, on the other hand, includes culture, structure, and human resources [33]. As such, it can be noted that KM infrastructure provides the infrastructural environment, both IT and non-IT that supports knowledge management activities [14] [34]- [36]. Furthermore, organizations should strive to develop infrastructure capabilities not only in terms of hardware and software, but also in terms of culture, structure, people, and technology [33]. [37] supported this by indicating that organizations that utilize both technical and organizational infrastructures are more likely to implement successful knowledge management projects.

Organizational Culture
Organizational culture has been defined as the specific collection of values and norms that are shared by people and groups in an organization and that control the way they interact with each other and with stakeholders outside the organization [38]- [41]. Organizational culture not only defines the value and advantage of knowledge for organizations, it also influences the ability of employees to share knowledge [42]. It has been reported that organizational culture is crucial for knowledge sharing and team work [14] [43]. The reason behind this is that organizational culture is pivotal in encouraging interaction and collaboration between individuals that is necessary for the flow of knowledge. It also provides individuals with the ability to self-organize their personal knowledge to facilitate problem solving and the sharing of knowledge [44]. In addition, researchers have reported that one of the most significant elements of culture for knowledge sharing to consider is trust. High levels of trust reduce the reluctance of individuals to share knowledge and decrease the associated risk of losing competitiveness [33] [45]. Therefore, creating a culture that allows for easy access of knowledge should be at the top of management's agenda during the implementation stage of knowledge management [42]. However, this is easily said than done as aligning the culture of the organization with the goals of knowledge management is considered a complex process, especially in organizations characterized by hierarchical structures and bureaucratic controls [46].

Organizational Structure
The connection between organizational structure and knowledge sharing stems from the social aspect of organizations that includes hierarchy, density, and connectivity that links employees together thereby facilitating the exchange of knowledge. Here authors suggest that two aspects of organizational structure affect the flow of knowledge; formalization and centralization [35]. Centralization refers to the extent to which decision making and the right to evaluate activities are concentrated at the top of the organizational hierarchy [47]. Formalization relates to "formal rules and regulations that govern organizational activities and manage work relations" [33], (p. 4). Therefore, organizational structure is considered an important factor for facilitating the flow of knowledge in organizations through the use of organizational policies, processes, and systems of rewards and incentives that determine how knowledge is accessed and subsequently flows throughout the organization.

Information Technology
Technology infrastructure thus plays a pivotal role in an organization's knowledge management system in terms of creating and using new knowledge, and sharing existing knowledge by incorporating various technological platforms. While hardware, networking, and bandwidth elements of technology are important, they are not sufficient to perform the KM activities of sharing, storing, disseminating, and maintaining knowledge. Other tools are thus required, like social media, content repositories, and dynamic websites [48]. Although technology enhances the organization's ability to conduct knowledge management activities, as a single construct it is not sufficient on its own. Technology therefore requires the support of other KM enablers such as organizational culture, structure, and business strategy to ensure that the right knowledge is be-ing managed in the right way [14].

Job Satisfaction
Job satisfaction can be defined as the extent to which an employee like his/her job [49].
Job satisfaction can also be seen as the affective, cognitive, and evaluative reactions of individuals towards their jobs [50]- [52] suggested that job satisfaction reflects the gratification and sense of fulfillment one receives from doing their job. [53] defined job satisfaction as the collection of beliefs and feelings people have about their jobs. [54] referred to job satisfaction as the degree to which individuals accept their work and their relationship with others in the work environment. All in all job satisfaction relates to how people think, feel, and perceive their jobs [55], i.e. their attitudes towards different aspects such as work itself, level of pay, promotion opportunities, and satisfaction with co-workers.
Over the years, various researchers have attempted to determine and classify the factors affecting job satisfaction. Two perspectives have emerged regarding the determinants of job satisfaction. The content perspective approaches job satisfaction from the perspective of needs fulfillment. Studies advocating the content perspective include Maslow's needs hierarchy, Herzberg's two factor theory, ALderfer's ERG theory, and McCelelland's theory of needs. The process perspective focuses on the cognitive process leading to job satisfaction. Process theories include Vroom's expectancy theory, Adam's equity theory, behavior modification, and cognitive evaluation theory [56] [57]. Both content and process perspectives have reported a sea of factors related to job satisfaction. These factors can be grouped into two broad categories: demographic factors and environmental factors. Demographic factors relate to individual attributes and characteristics such as: gender, age, job-level, and work experience. Environmental factors refer to factors associated with the work itself or work environment such as salary, promotion, supervision, climate management, fairness of appraisal systems, and satisfaction with coworkers [57]. Other scholars have classified job satisfaction factors into intense and extrinsic factors. Intrinsic factors relate to the actual work individuals do in the organization. Such factors include variety, skill utilization, and autonomy. Extrinsic factors relate to aspects of the work environment such as pay, working conditions, and coworkers [56].
Measuring job satisfaction has always been a challenge for both researchers and managers. A gap has always existed in most methods between what real satisfaction is and measured satisfaction. Therefore, creating a measurement method that is free from bias is a major concern in organizational behavior studies. Several methodologies exist for measuring satisfaction. [58] evaluated a weighted model, [59] focused on the stability of the job descriptive index (JDI), [60] challenged the facet importance of job satisfaction, [61] assessed asymmetric effects in satisfaction formation, and [62] debated the scale of JDI [63]. In conclusion, job satisfaction can be seen as a crucial social phenomenon for organizations, as it leads to the provision of high quality performance by improving the cohesion and morale of individuals. It is also important as it is closely related to working behaviors such as productivity and efficiency. Here satisfied employees have the motivation to improve their work behaviors, whereas unsatisfied workers tend to behave less effectively [64].

Knowledge Management Infrastructure and Job Satisfaction
Some researchers (e.g. [10] [35] [41] [65]- [67]) emphasize the need for large firms to integrate their IT with their KM strategies and processes in order to survive in their highly competitive business environments. In terms of organizational culture, many studies have been conducted to examine the link between culture and job satisfaction. The results of the studies are, however, quite contradictory. Some researchers have stated that organizational culture is one of the most important antecedents of job satisfaction, thereby indicating a positive relationship between organizational culture and job satisfaction (see [68]- [70]).
Whereas other researchers, such as [71] have argued that job satisfaction and organizational culture are not related. Organizational structure has been suggested to affect employees' judgements and perceptions and in turn play a significant role in human resource issues [72]. Therefore, organizational behaviorists and human resource professionals have long debated the preferred way to structure the work environment to affect employee outcomes [73]. [74] examined the relationship between organizational structure and job satisfaction. The researchers found that the two dimensions of structure (specialization and formalization) positively affected job satisfaction and that centralization had a negative effect on job satisfaction. [73] indicated that the structure of academic departments is related to faculty members' outcomes. More specifically, faculty members working in organically structured departments have higher levels of job satisfaction compared to other structures. [72] also investigated the relationship between organizational structure and job satisfaction and found that the dimensions of structure (complexity, formalization, and centralization) explain only 32% of the variation in job satisfaction, indicating that other factors should be taken into consideration in explaining the variation in job satisfaction.
Given that technology is considered one of the most important knowledge management enablers within organizations [9] [35] [43] [75], its effect on job satisfaction should be invesitagetd. The importance of technology for job satisfaction has been resported by several researchers. [76], for example, found that work technology was positively and significantly related to job satisfaction. [34]'s study results also showed that the use of IT and organizational structure has a significant influence on job satisfaction. These findings are supported by [77] who revealed that the more a company invests in IT, the more satisfied its employees will be with their working conditions, their relationships with colleagues and personal job characteristics.

Research Methodology
This section provides the methodology applied in the current study. It consists of the research model, operational definitions of the study's independent and dependent va-riables, research hypotheses, besides data collection tool and research population and sample.

Research Model
The major elements of this research are established based on preceding literature, either theoretically or empirically. Indeed, this study used variables that are common in knowledge management literature. Figure 1 represents a model for the study that shows the independent variables within the construct of knowledge management infrastructure, and the dependent variable (job satisfaction), and the proposed relationship between them.

Operational Definitions
The current research considers three independent variables within the construct of knowledge management infrastructure, and one dependent variable (job satisfaction). Further, knowledge management infrastructure includes organizational culture, organizational structure, and information technology. Organizational culture is a system of shared values and beliefs that produces norms of behavior and establishes an organizational way of life. The successful implementation of knowledge management requires an organizational culture that encourages employees to create and share knowledge [78]. A multi-item indicator was built comprising six items, including values such as trust, confidence, cooperation, learning, and recognition of expertise [31] [78]- [80]. [31] identified organizational structure as the formal rules and authorities that exist within an organization. Organizational structure has multiple dimensions include centralization, formalization, in addition to the incentive system, which is needed to encourage knowledge creation and sharing. Accordingly, organizational structure will be measured through six items in the research questionnaire adapted from [31] [80]- [82]. [81] defined information technology as the degree to which knowledge management is supported by the use of IT. Information technology playing an important role in knowledge management, it allow packing up the knowledge, facilitating access to  [83]. [84] add another dimension to measure IT infrastructure, which is End-User Focus and whether information systems and software are designed to be user-friendly. In this research six items are adapted from [30] [82] [84] [85]; to measure information and communication technology.
Job satisfaction in this research is defined as a construct of the degree to which the employee is satisfied and happy with the job [86], and validated by [41]. Job satisfaction is conceptualized as a combination of feelings about different dimensions of a job. Five dimensions provide separate measures of JS and consist of 14 items. These included being satisfied with pay and other compensation-2 items, job security-2 items, peers and co-workers ("social")-3 items, supervision-3 items, and opportunities for development ("growth" satisfaction) 04 items. After measuring employees' satisfaction with different elements of a job, a composite score of the items is calculated as a measure of overall satisfaction.

Research Hypotheses
In order to test the research model of the impact of knowledge management infrastructure on job satisfaction, the study is hypothesized as follows: H1: There is a statistically significant impact of organizational culture on job satisfaction.
H2: There is a statistically significant impact of organizational structure on job satisfaction.
H3: There is a statistically significant impact of information technology on job satisfaction.
H4A: There is a significant difference in the impact of knowledge management infrastructure on job satisfaction due to gender.
H4B: There is a significant difference in the impact of knowledge management infrastructure on job satisfaction due to age.
H4C: There is a significant difference in the impact of knowledge management infrastructure on job satisfaction due to educational level.
H4D: There is a significant difference in the impact of knowledge management infrastructure on job satisfaction due to personal income.

Population and Sampling
Empirical data for this study was collected through paper-based survey in 5 star hotels located in Aqaba city in Jordan. Specifically, a survey questionnaire was used to gather data for hypotheses testing from staffs that are familiar with knowledge management activities. Thus, a judgment sampling technique was conducted. Before implementing the surveys, the instrument was reviewed by four lecturers who are specialized in the hotel management discipline in order to identify problems with wording, content, and question ambiguity. After some changes were made based on their suggestions, the modified questionnaire was piloted on five staffs that are familiar with the hotel's knowledge management systems. Based on the feedback of this pilot study, minor edits were introduced to the survey questions, and the questionnaires were distributed to the participants. As per ethics policies, all potential participants were briefed about the nature of the work and were requested to provide explicit approval. 216 questionnaires were returned and considered for statistical analysis. The questionnaire consisted of two sections; the first section in questionnaire presents general personal information about a respondent such as the gender, age, educational level, and personal income. The second section includes questions to measure the independent and dependent variables based on their operational definitions.

Data Analysis and Results
In order to explore the impact of knowledge management infrastructure on job satisfaction, in which KM infrastructure variables have been measured using 5-points Likert scale that varies between not agree at all =1 and totally agree =5; and using 5-points Likert scale that varies between strongly dissatisfied =1 and strongly satisfied =5 for job satisfaction. Reliability and validity analyses was conducted, descriptive analysis was used to describe the characteristic of sample and the respondent to the questionnaires besides the independent and dependent variables. Also, multiple regression analysis was employed to test the research hypotheses beside ANOVA and T-test ones.

Validity and Reliability
Validity and reliability are two important measures to determine the quality and usefulness of the primary data. Validity is about accuracy and whether the instrument measures what it is intended to measure while reliability is about precision; it is used to check the consistency and stability of the questionnaire. Indeed, the researchers depended on scales and items that were previously developed and used by other researchers with similar interest. Also a draft of the questionnaire was formulated, and then it was reviewed by five academic lecturers-who have a sufficient knowledge and experience in this scope-to insure that each item is measuring what is intended to be measured, and to avoid the ambiguity and complexity in the phrasing of questions. The reliability of the instrument was measured by the Cronbach's alpha coefficient. Further, some scholars [87] suggested that the values of all indicators or dimensional scales should be above the recommended value of 0.60. Table 1 represents the results of Cranach's alpha for the independent and dependent variables. Cronbach's alpha coefficients of all the tested variables are above 0.60 which suggesting the composite measure is reliable.

Respondents Demographic Profile
As indicated in Table 2, the demographic profile of the respondents for this study showed that they are typically males, hold bachelor degrees, and 69.7% of the respondents have more than five years experience.

Descriptive Analysis
In order to describe the responses and thus the attitude of the respondents toward each question they were asked in the survey, the mean and the standard deviation were estimated. While the mean shows the central tendency of the data, the standard deviation measures the dispersion which offers an index of the spread or variability in the data [88]. In other words, a small standard deviation for a set of values reveals that these values are clustered closely about the mean or located close to it; a large standard deviation indicates the opposite. The level of each item was determined by the following formula: (highest point in Likert scale-lowest point in Likert scale)/the number of the levels used = (5 − 1)/5 = 0.80, where 1 -1.80 reflected by "very low", 1.81 -2.60 reflected by "low", 2.61 -3.40 reflected by "moderate", 3.41 -4.20 reflected by "high", and 4.21 -5 reflected by "very high". Then the items were being ordered based on their means. Table 3 and Table 4 show the results.  As presented in Table 3, data analysis results have shown that knowledge management infrastructure is applied to a great extent in Aqaba five star hotels in Jordan in which the mean score is 3.8183. This indicates an indicator on the importance of knowledge management infrastructure, and such high level of presentation denotes a positive attitude regarding the infrastructure of knowledge management. In addition, job satisfaction found to be high as well. This advocates that Jordanian five star hotels located in Aqaba city are currently engaging in job satisfaction activities to maintain competitive advantages. Table 4 demonstrates the mean scores for knowledge management infrastructure, and job satisfaction items.

Hypotheses Testing Results
The current research is mainly seeking to investigate the impact of knowledge management infrastructure (organizational culture, organizational structure, and information technology) on job satisfaction in Aqaba five star hotels in Jordan. Consequently, in order to test the hypotheses developed for this study, multiple regression technique was used. Further, the level of significance (α-level) was chosen to be 0.05 and the probability value (p-value) obtained from the statistical hypotheses test is considered to be the decision rule for rejecting the null hypotheses [89]. If the p-value is less than or equal to α-level, the null hypothesis will be rejected and the alternative hypothesis will be supported. However, if the p-value is greater than the α-level, the null hypothesis cannot be rejected and the alternative hypothesis will not be supported. In addition, normality of the independent variables and the absence of multi co-linearity problem (a case of multiple regression in which the independent variables are themselves highly correlated) were checked. According to [90], most of the values should be inside the adequate ranges for normality (i.e. −1.0 to +1.0). For this purpose, skewness and Variance Inflation Factor (VIF) were investigated; Table 5 includes the results.
As can be figured out from Table 5, the skewness values were within the normal values (1.0 to +1.0) suggesting that the data of the independent variables is normal. The VIF values were less than the critical value (10) which is most common among the most studies, suggesting no multi co-linearity problem among the independent variables. However, the results of testing the three hypotheses on the impact of knowledge management infrastructure (organizational culture, organizational structure, and information technology) on job satisfaction are demonstrated in Table 6.  Refer to Table 6 the multiple correlation coefficient R = 0.494 indicates that there is a medium positive correlation between knowledge management infrastructure (organizational culture, organizational structure, and information technology) and job satisfaction. The adjusted R 2 indicated the generalizability of the model. It allows us to generalize the results taken from the respondents to the whole population. In this case it equals 0.244. The results showed that F-ratio for these data is equal to 22.769, which is statistically significant at p < 0.05. Therefore, we conclude that there is a statistically significant effect of knowledge management infrastructure on job satisfaction.

The β indicates the individual contribution of each predictor (independent variable)
to the model, if other predictors are held constant. Table 6 shows the standardized coefficients for each knowledge management infrastructure dimensions. The value of β for organizational culture and information technology are 0.372, 0.192 respectively, which are positive and significant at p ≤ 0.05; thus H1 and H3 were supported. While for organizational structure, the value of β is 0.117, which a small value compared with other predictors and not significant at p ≤ 0.05; thus H2 was not supported. The level of effect of these variables depends on the β value, the higher β value the higher effect on dependent variable. We can infer from the values of beta that the variable that has the highest contribution in the model is organizational culture, followed by information technology. The variable organizational structure does not have a significant effect on job satisfaction.
Hypotheses H4A, H4B, H4C, and H4D argued that there is a significant difference in the impact of knowledge management infrastructure on job satisfaction due to gender, age, educational level, and personal income. Independent Samples T-test was employed in order to investigate if there any significant differences in the impact of knowledge management infrastructure on job satisfaction that can be attributed to gender. Also, ANOVA test was employed to examine if there any significant differences in the impact of knowledge management infrastructure on job satisfaction that can be attributed to age, educational level, and personal income. Results of T-test, shown in Table 7, indicated that there is a significant difference in the impact of knowledge management infrastructure on job satisfaction that can be attributed to gender. In addition, results of ANOVA test, shown in Table 8, Table 9, and Table 10, indicated that there are significant differences in the impact of knowledge management infrastructure on job satisfaction in favor of age, educational level, and personal income.

Discussion and Conclusions
This study aimed to identify the role of KM infrastructure (organizational culture, or-ganizational structure, and information technology) in enhancing job satisfaction at Aqaba five star hotels located in Jordan. The results found that knowledge management infrastructure is applied in the studied five star hotels in Jordan. Furthermore, data analysis results have shown that job satisfaction is effectively applied as well. This high level of application reflects a positive attitude toward employees' job satisfaction. Our results also indicate that Aqaba five star hotels in Jordan give careful attention to job satisfaction-related dimensions; they focus on being satisfied with pay and other compensation, job security, social impacts, supervision, and opportunities for development. Moreover, the results indicated a positive effect of organizational culture and information technology on job satisfaction; whereas no statistically significant effect found of organizational structure on job satisfaction. Moreover, the results of T-test indicated that there is no significant difference in the impact of KM infrastructure towards job satisfaction in favor of gender. Also, results of ANOVA test found that there are significant differences in the impact of KM infrastructure on job satisfaction that can be attributed to age, educational level, and personal income.   The first hypothesis stated that there is a statistically significant impact of organizational culture on job satisfaction. This result is consistent with the result of [91] that organizational culture had a significant effect on job satisfaction. This result is also supported by a number of studies showing that job satisfaction can be enhanced by organizational culture (See [68]- [70]). [41] found that emotional intelligence in terms of perception and appraisal of emotions, facilitating thinking with emotions, understanding emotions, and regulation and management of emotions can be used to predict job satisfaction. Consequently, the understanding of emotional intelligence theory and its applications can be promoted for managerial and human resource practices in public sector organizations.
The second hypothesis argued that there is a statistically significant impact of organizational structure on job satisfaction. This result is supported by the findings of [71], who found that job satisfaction and organizational culture are not related. Also, [78] argued that centralized organizations restrict the contribution that employees can make in performing their work, restrict knowledge sharing, and suppresses innovative solutions. However, this is against other researchers findings (e.g. [72]- [74]) who emphasized the impact of organizational structure in terms of complexity, formalization, and centralization on job satisfaction.
The third hypothesis stated that there is a statistically significant impact of information technology on job satisfaction. This result is agreed with [76] and [34] findings, as they found a high correlation between work technology and job satisfaction. Also, this result is supported by the findings of [77], who revealed that the more a company invests in IT, the more satisfied its employees and in turn increased job satisfaction characteristics. [92] stressed the importance of information and communication technology tools to innovation. The researchers found that information and communication technology can support knowledge management processes, which in turn promote flow of knowledge into the organization, which assist organizations realize their innovation potential.
The implications of this research should be addressed in light of the study's limitations that future research should address. The first limitation is related to the study instrument, the study used closed-ended questionnaire items to measure the effect of knowledge management infrastructure on job satisfaction. This type of question is easier and quicker for the respondent to complete and simpler for data analysis; however, it limited the responses because the participants could not make any inquiry or explain their answers in more depth. However, the second limitation of the study was the poor responsiveness of the hotels due to privacy issues; the hotels refused to participate in the study although it included general questions that did not affect their privacy. The third limitation is related to the participants of the study. In this context, there is a chance that some participants might respond positively as they want to provide a positive image about their hotels, consequently, indepth interviews are needed for future research. The fourth limitation is the use of judgment sampling, which is may not representative of the population, and this will affect the generalizability of the findings.
Indeed, in connection to this study, knowledge management infrastructure explained 24.4% of the variations in job satisfaction; future researches and studies should focus on studying and investigating other factors that may enhance employees' job satisfaction.
Also, because of the conflicting results regarding the impact of organizational structure on job satisfaction, further research is needed to explore this relationship. Finally, this study was applied on five star hotels in Aqaba city in Jordan; therefore, the finding cannot be generalized to other sector of industries or in other countries.
