  • ABSTRACT

    During the last two decades of the 20th century, economies globalization, markets deregulation and the privatization of governmental monopolies, have significantly changed the way companies and markets, work. The new, complicated competitive environment intensified the need for operational control, but moreover the need for comprehension of the competition.

    Historically, the traditional financial tools (profit indexes, return of investment, etc.), which have been the most important source of information for the administrative executives, proved to face limitations compared to the market needs. Scientists realized that the pressure for immediate financial profitability could lead to short-term results, but this could undermine the companys ability to produce future economic value, through the sustainable development of elements, such as organizational culture. In the modern, globalized, business environment, where firms compete for a sustainable competitive advantage, profits are still thought to be important, but the way they are obtained, is considered to be first priority.

    Telecommunications providers should take into consideration these operational changes, and to adopt, soft core factors, such as organizational culture. Managers should be able to give solutions in problems related to the coordination between organizational characteristics and desirable business strategy, as well as to answer the question how this coordination can prevail intensive market competition. Furthermore, understanding leaderships role is of high importance, in order to understand the way managers formulate operational structures and the relationships with external associates (customers, suppliers, competitors and state). Moreover, managers and regulators should have the ability to understand how organizational characteristics, such as size and age, affect perceived work conditions, so as to develop financially effective structures and to obtain the best operational result.

    Under these circumstances, telecommunication industry has been selected, in order to understand and present its organizational structure, operational strategy and its main business indexes. The specific industry has been chosen as a representative of the whole market because of its substantive organizational and business characteristics that permit international comparisons. The market is characterized by free and intense competition, while no entry barriers exist. The technological, economic and regulatory developments affect directly the market, and phenomena of acquisitions, mergers and strategic alliances redefine its boundaries. In most developed as long as in the developing countries, telecommunication product is a validated entrepreneurial and consumable product, while its usage can determine the countries overall economic potentials (in terms of Gross Domestic Product), according to several studies. Finally, the telecommunications market is mature, as it has made its way from quantitative financial indexes to a multifactoral system, which consists of both quantitative and qualitative indexes. This fact allows conducting research; in order to conclude about a firms competiveness and business success, but moreover on how these can be achieved.

    Organizational structure and operational strategy, have been determined by measuring fixed and mobile operators organizational culture, along with their in between interactions. The studys aim is to understand the specifications of: a.) each company, b.) each industry (fixed-mobile telephony) and c.) the market as a whole. Organizational

  • structure, operational strategy and efficiency indexes are determined through the interdependent relationship between organizational culture and:

    markets competition level,

    leaderships character,

    companys size,

    companys age,

    market orientation and

    performance indexes.

    All these are examined in order to determine strategies or / and business practices that will enable: researchers to make international comparisons, administrative executives to practice effectively their duties and regulators to define measures for attaining a better level of competition, according to markets characteristics.
