Create a 4 pages page paper that discusses critical evaluation of the 3 school of thought on innovation and services. Furthermore, the manufacturing sectors have been vital for several economists as it has been the foundation stone for the understanding of the process of innovation and its economic implications (Gallouj & Windrum, pp. 141-142, 2008). The learning and understanding of service innovation, on the other hand, have now become an opportunity for scholars where they can widen and enlarge their knowledge of an incorporated account of innovation and its entire process that applies to services as well as manufacturing. However, several prime issues and debates have been a significant part of the research for different schools of thoughts that have erupted and fumed in the literature of the service innovation over the past couple of years. According to one school of thought, the discussion and argument revolved around the subject matter that portrayed the potentials of innovation in services in contrast to the manufacturing along with its implication in the growth of the economy and employment (Gallouj & Windrum, pp. 141-142, 2008). According to the viewpoint of few scholars, the subject matter of innovation in the service sector is a concern that has gained significant importance over the period of instance. Moreover, the empirical and theoretical studies have contributed to great deal in determining the substance of innovation that plays a prominent role in the service activities in productive systems. In addition, these scholars also exhibit the piece if information that building or defining a definition of innovation on a general basis is fundamental and essential as it would create the perceptive and awareness of the concepts and dynamics of innovation in both sectors comprising service and manufacturing (Gallouj & Weinstein, pp. 537-538, 1997). The research has proved that the concept of innovation in services dates back to several centuries that have come under rematerializing few times. In fact, the arguments and discussions then focused around the alleged assimilation, demarcation, and synthesis discussion. According to the assimilation standpoint, the service activities and manufacturing activities possess the similar functions on whole, and thus the theories and experimental or observed indicators are applicable to the services in the same way that have primarily and initially come under development for the manufacturing. According to some beliefs, it has also come under view that services in innovation are just the consequence of change that occurs due to dispersion of innovation (Gallouj & Windrum, pp. 142-143, 2008). However, the demarcation perspective is the antipode or reversal of assimilation, which states that service-specific forms of innovation exist. Furthermore, the organizational importance has been the key point of prominence with product and process innovation in services. Indeed according to the scholars who believe in this view strongly argues that various forms of innovations are service specific, therefore, it is critical and crucial to have exclusively new theories of innovation that must be service specific in order to have a clear understanding of the nature and motion of innovation in services (Gallouj & Windrum, pp. 143-144, 2008).
