This increase is mainly attributed to the changing needs and demands of the customer base. Change in social needs and their importance in company survival has resulted in more and more innovations[Ash11]. The social influence on innovation can be explained through several postulated theories that have been considered of importance by innovation specialists[Hei04]; Technology push theory; innovation that is derived from science. Social network derived innovation Market pull theory; innovation that is derived from market and customer needs.
Technological network derived innovation. Innovation that is derived from linkages between the players in the market. The technology push theory of innovation management also referred to as engineering theory of innovation management is the first theory of innovation management. According to this theory the opportunities available for innovation which include the improvement of the manufacturing process and the final product is influenced by input of research that has been carried out as pertaining the product.
Research is the source for the improvement of the production process and the final product, the input of the result of the research outcomes follows a linear progression from the research to identification and definition of the product, the definition of technology to be used in the production of the product, the definition should conform to the results of the research[Hei04]. The technology push theory of innovation faced some challenges as the products were at some point not doing well in the market, this resulted in another theory called the Market pull theory of innovation management .
This theory accepts and recognizes the importance of research in the acquisition of knowledge to improve products in the manufacturing processes. According to this theory ideas and knowledge on improvement should be from the market and research in addition to this organizational competence and technical feasibility are the two most important factors that must be considered for successful innovation[Hei04]. Thereafter the chain link theory of innovation was introduced which tried to ascertain the concept that the connection between knowledge and the market is not as simple as it is assumed by the technology push and the market pull theories.
According to this theory a connection is established between research and the market through technological and engineering production, sales and marketing. Later there was a linkage established between the companies and their respective clients and customers[Hei04]. In the late 1980s and in the 1990s, technological networks theory of innovation management was developed this theory assumed that the firms are highly interconnected and linked through the sharing of information and data .the theory emphasizes on the importance of taking into account the source of this information which at most is external to the organization[Hei04].
The social network theory of innovation management is linked to the two previous ideas, as per the technology push and market pull theories the idea is that innovation is mainly influenced by research and the inevitable interactions between the companies and other players innovation is also fostered much by knowledge, the importance of knowledge has resulted in the mass accumulation of information and data. The use communication technologies and social networks have made the dissemination and distribution of this data and information easier and faster in a wider and international scale[Hei04].
The evolution from a technological network perspective of innovation management to a social network perspective has been led by the challenge to transform information into knowledge (e.g. information contextually connected to the development or improvement of products or processes). Knowledge-based innovation requires not one but many kinds of knowledge. Furthermore, it requires the convergence of many different kinds of knowledge retained by a variety of actors[Ash11]. 3.
