The importance of the existence of a powerful and dynamic high technology company sector in the current world economy is enormous as it vastly influences the potential for the global competitiveness of different nations or regions. In the developed, post-industrial economies, the leading technology companies sector is frequently regarded as the area with the most extensive use of and dependency on the so-called unique means of production – knowledge and human resources. These means are created continuously, which enables not only competition among individual companies but also has a positive effect on the surroundings (traditional industries, level of science, etc.). The high technology sector also requires continuous and intense innovative activities as well as extensive research and development investments.

Most of the previous studies of the high technology sector have focused on the issues related to the methodology of measuring the research and development activities and its results, the amounts, structure, and sources of financing, institutional solutions, and the role of the state in stimulating the scientific and technological progress as well as on the issues of technological advancement in a broader context of innovativeness. However, there have been few studies of high technology companies’ functioning and management.

Top tech companies of India

The Indian software industry is now in its third phase – that to take off. Today, most leading companies are operating in the high-end software services business and are also making efforts to enter the products segment. A new breed of companies, led by second-generation software entrepreneurs, are setting up product-oriented companies. The industry has weathered ups and downs in the global market, maintaining a high rate of growth. The industry moved centre stage in the domestic media because of its visibility in the United States, increased market capitalization and wealth creation for its employees. It is a source of social pride and as a consequence continues to attract disproportionate government attention.

The government set ambitious software export targets and has provided the policies to enable the industry to achieve those targets. Software companies are increasingly in recognition of their leadership in adopting best practices in management by the media. Indian companies have fine-tuned the “offshore model” and project their brands as service companies. Companies have moved further up the value chain, improving productivity, targeting new geographies, vertical domains and businesses.
