Competitive Advantage Based on Human Capital and its Impact on Organizational Sustainability: Applied Study in Jordanian Telecommunications Sector

The current situation facing business organizations is characterized by diverse work environments with continuous change and development. Todays organizations seek to keep pace with this continuous development and operate to maintain their current business through the ability to effectively respond to change, and to create competitive advantage based on the existence of qualified human capital that contribute to the creation of organizational sustainability in the business sector. Talented human capital, with special skills, has the potential to create confidence and integration among the staff and top management, leading to organizational growth and continuation (Kurucz, 2013). The emergence of a set of challenges in the knowledge economy has had a clear reflection on business organizations which have begun to search for new mechanisms to compete and insure their existence in the business world. Hence, the importance of the concept of competitive advantage, based on human capital, as a necessary requirement to deal with the challenges faced by local, regional or international organizations (Global Institute, 2011). Where competitive advantage based on human capital is the main generator of new ideas, development of old ideas, and contribution to aid in organizational abilities to expand their current market share as well as maximizing value. Competitive advantage based on talented human capital allows organizations to be able to seize new opportunities and achieve permanence and future continuity (Thomas, 2014). This study aimed to look at the impact of competitive advantage through intellectual capital investment as one of the elements in the creation of organizational sustainability in the Jordanian Telecommunications Companies sector. Simple and Multiple regression was used for data analysis and testing the hypotheses of this research .This study has reached a set of results that previous studies reinforced in this area such as: Competitive advantage based on a distinct capital is the optimum method that should be used in telecommunications companies since it contributes to the optimal investment of human capital. This leads to optimum organizational sustainability for companies in various fields and also contributes to the achievement of a company’s mission and vision of the future.


Introduction
The concepts of sustainability and competitive advantage have received great attention from researchers due to the successful role that they are playing in achieving high organizational performance, which is an essential base for sustainable progress, development, and growth.Various fields of life are characterized by change and are closely linked to the style of work adopted, and the extent of understanding of the organization's psychology.The influence of achieving a reasonable balance between building a human capital-oriented competitive advantage and maintaining organizational sustainability needs (i.e., sustainable growth) should be taken into account by the business organization (Elizabeth, 2013).To ensure continuous growth, development and an innovative capability, business organizations should find the most suitable work mechanisms, based on competitive advantage elements, to determine the path to create stable and efficient organizational sustainability and encourage the development of strategic thinking (Cham, 2004).These steps will definitely help organizations handle the expected challenges they might face in the future, and preserve organizational efficiency, effectiveness, and survival under a changing and disturbed environment (Bani Issa, 2006).The emergence of the sustainability concept has received considerable attention by researchers and business organizations, especially the human capital concept, due to the intensive competition in the business field.The increase of environmental uncertainty and the emergence of a knowledge economy have played an influential role in the communications revolution and the rising information deployment phenomenon (Salman, 2009).Therefore, business organizations began looking for new mechanisms to be used in global competition as a prerequisite to ensure survival in the business world.In light of these local, regional and international challenges, human capital has been considered as a necessary element to help business organizations to be able to handle these challenges (Oasis, 2015).Human capital encompasses all individuals who have the knowledge and organizational capabilities that enable them to create new ideas and improve the old ones in order to facilitate the expansion of the organization's market share .This would insure consolidation of the organization's strengths, eliminate its weaknesses and boost its competitive advantage.Therefore, it would be relevant to conclude that organizational survival actually relies upon a continuous implementation of sustainable development planning (Catrin, 2011).Jordan is categorized as one of those countries which are suffering from a scarcity in its natural resources.This fact has urged the Jordanian government to pay great attention to the development of the country's human resources as the most important asset for sustainable economic growth.To achieve this objective the Jordanian government has allocated a considerable percentage of its annual budget to education, this was in parallel with a large investment made by the private sector also, especially in the last two decades.According to the Jordanian Ministry of Higher Education, Jordan has met its national educational ambitions and has achieved the expected output of its investment in human capital (Jordanian Ministry of Higher Education and Scientific Research, 2004).Based on what has been stated previously, it is reasonable to suggest that human resources are the most valuable national resource in the Jordanian economy and the core of its national competitive advantage.This denotes very clearly the important role of Jordanian human capital in the achievement of business sustainability in all sectors of the Jordanian economy.

Problem Statement
Competitive advantage plays an important role in business organizations through helping them to survive, continue and maintain their current functions by creating sustainability in the business sector (Kurucz, 2013).Organizational objectives cannot be fully achieved without the attainment of competitive advantage based on the existence of intellectual capital and not just the reliance on equipment, buildings or appliances (David, 2015).However, the human capital investment requires wise and sound leadership capacity which recognize the importance of the human element and its components, and which have the ability to influence it in a positive way.Sound leadership of the human capital investment will accomplish conversion into competitive advantage, aiding in the creation of organizational sustainability and achievement of the organization's objectives (Al-Dahan, 2005).Hence, the questions of the study can be developed through the idea that human capital investment is an essential means to create competitive advantage for the organization and to enable it to continue and create organizational sustainability in the best way possible, enabling the organization to achieve its vision of the future.In order to counter the above problem methodically, the following questions were formulated:

•
What is the level of the human capital investment in the Jordanian Telecommunications Companies Sector?
• Does the human capital investment contribute in the creation of competitive advantage in the Jordanian Telecommunications Companies Sector?

•
What is the effect of the presence of competitive advantage based on human capital, in creating organizational sustainability and its elements to continuity and success in the Jordanian Telecommunications Companies Sector?

Objectives of the Study
The main objective of this study is to understand the impact of competitive advantage through intellectual capital investment as one of the elements in the creation of organizational sustainability in the Jordanian Telecommunications Companies Sector.From this main objective we can design the following objectives: A. Create a theoretical framework to identify competitive advantage and organizational sustainability in terms of the concept, importance and dimensions.
B. Identify intellectual capital in terms of the concept, importance and elements.
C. Clarify the relationship between the variables above.H2: There is a statistically significant impact for competitive advantage based on human capital, to achieve sustainability from the innovation ability in the Jordanian Telecommunications Companies Sector.

D. Identify the level of competitive advantage application in the Jordanian
H3: There is a statistically significant impact for competitive advantage based on human capital, to achieve sustainability from the collective work in the organization within the Jordanian Telecommunications Companies Sector.

Population of the Study
The population of the study consists of the employees in companies who work in the Jordanian Telecommunications Companies Sector which amounted to (3) companies, namely (Zain, Orange, & Umniah).The total number of employees reached therein (19000) and through the determination of employees who meet the human capital characteristics, (500) employees were identified, as representing the population of the study.

Sample of the Study:
Based on statistical equations used to determine the size of the sample (120) persons have been identified and were distributed as follows:

Method of Data Collecting
The means of collecting information were divided into two parts: The researcher conducted an audit and survey of the various theoretical and field studies related to competitive advantage, human capital and organizational sustainability.Scientific books and journals, Arabic and foreign, master's and doctoral theses, in addition to reliable information on the Internet were reviewed.

• Second Part:
A questionnaire was developed to reflect the role of human capital in the creation of competitive advantage and its impact on achieving organizational sustainability.The questionnaire was developed after reviewing questionnaires used in previous studies, and it was presented to a number of arbitrators to ascertain the viability of the content.All the necessary amendments were made to the paragraphs of the questionnaire before it was distributed to the study sample, which consisted of the staff of Jordanian Telecommunications Companies Sector covered by the research.The Likert Scale was used to measure the questionnaire content as follows: (1) For the Strongly Agree, (2) For the Agree, (3) For the Neutral, (4) For the Disagree, (5) For the Strongly Disagree As for the statistical methods used, the Statistical Package for Social Sciences (SPSS) has been used and will be explained in detail in the chapter concerning this aspect.

Competitive Advantage
The subject of competitive advantage is highly attractive to a large number of researchers because of its impact in all areas of the organization, since competitive advantage is one of the most important factors affecting the success of organizations (Al-Dahan, 2005).As a result of the growing complexities in the business environment, and the increase in the intensity of competition between organizations, the need for organizations to possess unparalleled indicators has emerged.Organizations must occupy a leading position in the market through their ability to provide a better product or service, as compared to the competition.There are many concepts of competitive advantage, including the distinction of the organization as compared to other organizations in the same field (Bradshaw, 2014), as well as the pursuit of the organization to own special attributes that distinguish them from other organizations working in the same field (Wei, 2015).From the afore mentioned, it can be said that competitive advantage is the ability and capabilities possessed by the organization in all its elements through which it can make something of high value that the competitors cannot imitate or offer better, and is achieved through referring to a cognitive processes with clear managerial methodology.The possession of competitive advantage by the organization can help it to develop the means and methods to meet the challenges of the market, as well as the ability to meet the needs of customers, leading to the success of the organization.An organization with competitive advantage uses empowerment strategies and emphasizes the possession of the factors of successful production, fundamental capabilities and knowledge of the factors in the external environment, in addition to building integration, which contributes to the expansion of the value chain, enabling it to achieve its survival and continuity (Barnett, 2007).

Human Capital
The contemporary trends in modern management include new subject features that care about intellectual assets more than the physical assets, since maximizing the physical assets comes as a result of the availability of intellectual assets.This new subject is human capital, which has become, in the era of technology, the real stimulus in the success of organizations (Ching-Fu, 2015).Human capital is the intellectual ability capable of generating new ideas, appropriate processes and a high level of quality as a main stimulus for sustainable growth and achieving sustainable development, which in turn contribute to achieving the optimum investment for different resources to reach the objectives (Smith, 2007).Human capital is also the driving force of competitive advantage for business today, where human capital represents the innate capacity acquired in individuals which lead to an increase in the economic value added in all areas of business, if properly invested.As a result of the significance of this subject, researchers in Administrative Sciences have given great importance to human capital, especially in developing countries (Patrick, 2015), where they provide a lot of definitions in order to determine its concept.Some consider human capital as part of organizational work, others view it as including a set of components associated with the employees, a third group sees that it includes the education, experience and skills possessed by them , while some consider it as directly linked to the work (Pennington, 2015).

Importance of Human Capital
The human element is the basis for an organization's existence and development, and it supports the organization's success and continuity (Jounes, 2013).Human capital plays a key role in dealing with the problems faced by the organization, and the development of appropriate solutions that lead to meeting the challenges faced by the organization (Noe, 2009).
It is a fact that human capital is the main factor that leads to the organization's success, and not buildings, equipment or trademarks (Decenzo, 2005).Thus, human capital has great significance in the success, continuity and survival of organizations.Below is a detailed explanation of this importance: Leading companies develop strategies related to human capital, which are considered of utmost importance for identifying and seizing appropriate opportunities through skills and knowledge of talented employees with entrepreneurial abilities that result in achieving competitive advantage.Kurues (2013) confirmed that human capital is the main arm of the organization in today's world.Intellectual assets represent the hidden force that ensures the survival of the organization and its success and profitability, by working to focus on the main idea that should be addressed, while drawing from the support and innovation policies of human capital (Helen, 2015).
Human capital achieves the strategic objectives associated with improving work performance and development of organizational culture, to reach the creativity and innovation which leads to the success and survival of the organization (Dessler, 2003).The survival, growth and continuity of the company depend on the ability of employees to provide the necessary and important knowledge for survival, i.e., on the human capital that they own.In addition to this, the importance of human capital emanates from achieving three basic necessities which include necessity for success, necessity to create new knowledge and the necessity to achieve competitive advantage, through the ability to use characteristics convertible to innovations of great significance, to help decision-makers to take decisions related to sustainable growth in the organization (Helen, 2015).

Organizational Sustainability
The subject of sustainability is one of the modern subjects in business that has received considerable attention from researchers.Achieving profitability, increasing market share and achieving entrepreneurship and distinction are no longer the main subjects in an unstable environment.Organizations look beyond and focus on creating a state of sustainability and continuity and maintaining the current business through the ability to meet the current needs for sustainable growth (Fernandez, 2012) as well as the ability to be superior to their competitors.This requires the organization's attention to the sustainability of competitive advantage now and in the future (Ramazan, 2009) and in various aspects such a: sustainability of the organization's relations, sustainable ability for innovation and sustainability of collective work, and its association to the elements of its competitive advantage that contribute to this state of achievement, in which its human capital constitutes the key element in its continuation.
Many researchers have defined the concept of sustainability where White (2013) defined it as the process of creating a continuous value for current and future generations.Landrum (2009) enhanced this concept when he said "The organization's ability to maintain the organization's resources, assets and funds over the long term".
Jones (2016) went on to say that it is the organization's ability to remain in the exercise of their activities in the long term and to achieve high growth rates.Michael (2015) said it is the organization's ability to continue and survive as a strong organization in the environment in which it operates long-term with the necessity of the presence of indicators reinforcing this continuation to confirm the increase of this force.
The creation of organizational sustainability requires the availability of a set of requirements as defined by (Barmwel, 2010) the most prominent are: the existence of the organization's continuation indicators, high rates of growth, attracting the best customers, achieving staff satisfaction and loyalty, optimum use of resources, supporting competitive ability, searching for points of strengths, weaknesses, opportunities and threats, and a continuous commitment to the innovation processes.It also includes working to overcome the obstacles of organizational sustainability represented in multiple measurements to measure the sustainability, government policies, lack of consistency between the sustainability and the business sector, the difficulty of distinguishing between the opportunities and threats in the future, and lack of knowledge of ways and means to motivate employees that participate in creating competitive advantage based on human capital through the use of organizational sustainability (OSM) (Michael, 2015).For the success of the organization, a set of points must be taken in to account when formulating sustainability strategy, these include: determining the motives of work and identifying the organization's vision clearly, in addition to understanding the current organization's position and the development of the workers capacity, and finally, determining the plan of action needed to create sustainabil point in c following Note.Prepare

Discussion of the Results
The results have shown that human capital has a great impact on the creation of competitive advantage for the telecommunication companies in Jordan, where human capital operates on the creation of competitive advantage.Human capital constitutes the base in its creation, and the use of this competitive advantage is working to achieve organizational sustainability for these companies.This leads them to possess sustainability in relation to other telecommunication companies with which they work, and with their customers.Achieving success and development of these companies appeared in the results of this study which amounted to the value of (T) is (8.31), shown in table 3. Also, sustainability in finding ability within these companies and their employees to generate new ideas, generation of new knowledge, characterized in the introduction of new ideas and the generation of creativity in all areas of their work, making them distinct permanently and continuously from the rest of the companies operating in the same sector or other sectors, and can be seen in the power of impact that appeared in the results of the study, which amounted to (11.90), table 4.
Furthermore, the creation of collective work sustainability, through the completion of business in the telecommunications companies in accordance with the action teams, has differentiated the companies from other companies and has had significant consequences for the success of the companies in achieving their objectives efficiently and effectively, where the impact value reached (7.52) as is shown in table 5.By looking at the overall condition of the companies, results have shown that creating competitive advantage, based on the existence of a distinct human capital, will contribute to creating and finding a state of sustainability and successfully achieving objectives.
