I. Introduction
In the modern economy, we put much pressure on innovativeness to make our lives better as well as to earn more money by winning the business competition among countries or companies. According to Oslo Manual-Guidelines [11], innovation is something new or substantially enhanced in this way that it is useful for a customer or economically beneficial for a company implementing it. Innovations are categorised as a product, a process, or a marketing tool. Nowadays, we tend to substitute traditional titles like an engineer, a scientist, an inventor by one term an innovator [20] What is more, each employee may be an entrepreneurial unit inside a company, if it provides a proper working environment, for instance, it offers a flat organizational structure, one day a week for research or other activities, a program rewarding innovations [17].
