1. Introduction
The relevance of innovation in the public sector (IPS) has been recognized in the literature. Mulgan and Albury (2003) consider that IPS is a core activity in increasing the responsiveness of state services to local and individual needs; helping to contain cost pressures by improving efficiency in the provision of public services; and improving the results of public services. For their part, De Vries, Bekkers and Tummers (2015) identified studies that emphasize the achievement of efficiency and effectiveness objectives thanks to the implementation of IPS.
Given the foregoing, it is not surprising that interest in IPS has increased in the last decade. Thus, for example, Matthews, Lewis, and Cook (2009) have found that 52% of the total number of articles related to this topic published between 1971 and 2008 in the Thomson-Reuters database correspond to the period 2006-2008. The increasing attention paid to this topic has led to the incorporation of special sections dedicated to the subject in books, and the publication of scientific articles in specialized journals (Van Duivenboden & Thaens, 2008). Despite the increase in absolute numbers of IPS-related publications, they still represent only a small subset of the total number of publications on innovation (Gow, 2014).
As part of this boom, studies have been carried out to identify the factors that inhibit or promote the generation of IPS from a theoretical or documentary perspective (De Vries et al., 2015; Kamal, 2006, Glor, 2001). However, the contribution of empirical evidence to the study of this phenomenon has been not enough (Potts & Kastelle, 2010; Pärna& von Tunzelmann, 2007; Vigoda-Gadot, et al., 2008; Damanpour & Schneider 2008). In addition, most of these studies have been carried out in the United States and England, giving them an Anglo-American perspective (De Vries et al., 2015).
On the other hand, research on IPS has focused mainly on the factors that promote innovative behavior in individuals (Borins, 2001;Damanpour& Schneider, 2008; Fernández & Moldogaziev, 2012; Yu et al, 2013; Nijenhuis, 2015), or on the generation of innovation at an organizational level (Riivari et al., 2012; Shoham et al., 2012; Bugge et al., 2011; European Commission, 2010; Hughes, Moore, Katarina, 2011; APSII, 2011), and less attention has been paid to innovation in work teams (Caldwell & O'Reilly III, 2003).
Although these three levels of analysis overlap – that is, the factors that affect the individual and the organization can affect the generation of innovation in work teams (Sears & Baba, 2011; Woodman, Sawywer & Griffin, 1993) – it has also been pointed out that the factors that promote innovation at one level can inhibit it at another, so each level must be explored to better understand the network of relationships that encourage innovative activity in the organization (Anderson, De Dreu & Nijstad, 2004).
Taking these points into account, this study focuses on identifying and understanding those variables or factors that induce or inhibit innovative activity in work teams of public organizations, in a developing country. To this aim the study has been organized into four sections. The first presents essential concepts of the study and the determinants of innovative activity in work teams that have been discussed in the literature, to provide a reference for the analysis of results. The second describes the method, while the third section presents the main findings of the study. The fourth section presents conclusions and suggests further lines of research.
5. Discussion and Conclusion
The purpose of this research was to identify and understand variables that promote or inhibit innovative activity in work teams of public organizations in the context of a developing country. The analysis of 213 citations allowed the identification of 19 categories of variables linked to the capacity to generate innovations in work teams. This set of innovation drivers are multidimensional and multilevel, as suggested by heuristics in the literature (Kozlowski & Ilgen, 2006, West & Hirst, 2003). The thematic contents of these categories, as expressed by the interviewees, allowed grouping them into four levels: external to the organization, organizational context, dynamics of the team, and characteristics related to team members.
The present study also reveals diverse mechanisms that underlie these categories. In the first level, a greater portion of verbal expression was found to be related to the exposure of public organizations to different actors that become sources of external pressure to promote or inhibit innovation, as suggested by other authors (Rogers-Dillon, 1999, Lonti & Verma, 2003). For example, the media promote innovation when they publish news that emphasize the search for novel solutions to problems, but they also inhibit it when they report errors or failures of innovative projects. Exposure of public organizations to media scrutiny can therefore increase the fear of taking risks (Mulgan and Albury, 2003). It can also inhibit the wish of high-ranking politicians to promote changes, since the failure of an innovative project could detract from their other efforts or have negative consequences on their political careers (Mulgan & Albury, 2003, Koch & Hauknes, 2005).
Politicians who come to occupy high positions are also external actors with the ability to promote innovative projects in work teams, or to curb them, especially when existing authorities are replaced with others who do not wish to continue with innovative ideas promoted by their predecessors, as stated by two interviewees. Private external agents can become an inhibiting factor when an innovative project threatens their economic interests, leading them to apply pressure to stop its implementation. On the other hand, users of public services are a source of pressure for innovation when they demand changes, but are also a source of valuable information for organizations without waiting for users to generate pressure to know what areas to innovate in. There are organizations that develop the necessary means to obtain user feedback through surveys, suggestion boxes, or other mechanisms. In these cases, it is the internal dynamics of the department rather than external pressure that allows them to obtain innovative ideas.
Another aspect of the external context which was perceived to exert an influence on the ability to generate innovation in work teams is the regulatory framework. Comments of interviewees emphasized that regulations, which the public sector is subject to, can cause a good idea to not even reach the stage of implementation, due to difficulties with changing rules or laws. This is in line with reports in the literature that a regulatory framework within a centralized and hierarchical institutional framework affects the degree of authority and availability of resources that can enable work teams to initiate innovations on their own (Micheli et al, 2012; Kovács, 2012). However, an idea that is supported by regulatory or legal frameworks has a great potential to be implemented
On the other hand, the qualitative data collected points to positive contributions of inter-institutional relations in the generation of innovation by work teams. These links are useful in discovering practices and innovations that other teams (in similar local or international public organizations) have implemented, and also allow access to knowledge and resources that other organizations have. This is in agreement with what was reported by several researchers who have found that it is not possible to promote and sustain innovation when organizations are self-centered (Osborne & Brown, 2011). All this seems to point to the conclusion that to promote innovation in work teams, it is essential to create open systems of collaboration between organizations and society. De la Maza (2003) states that collaboration of different social agents is required to achieve radical innovations, and that it is therefore vital to improve connections and links between organizations and society. In turn, the joint participation of diverse actors contributes to reflecting the diversity of visions of the population, which creates legitimacy in what is done (Van Buuren & Loorbach, 2009).
In the organizational context level, the study confirms variables identified in the literature that affect the ability of teams to innovate, such as: having a unit or program dedicated to research and innovation (ARC Fund, 2013); having the financial, human or other necessities required by an innovative project (Mulgan and Albury, 2003, Koch and Hauknes, 2005, ARC Fund, 2013, Maranto & Wolf, 2013); and having the support of high-level authorities in the development of new projects, especially those with a wide scope (ARC Fund, 2013, Vigoda-Gadot et al., 2008). In addition, this study highlights the negative effect on the development of innovative projects in work teams of a lack of technical knowledge on the part of managers with the power to allocate budget or support it. As a result, the ability of a work team to easily explain the technical details of a project and to clarify the costs/ benefits of the project to authorities becomes relevant.
Another essential element recognized by some interviewees in successful innovation is that the organization has a clear direction and a well-defined strategy to achieve its objectives and goals, which not only helps to visualize what types of innovation are needed, but also leads the team towards a goal that allows to trigger and justify innovative solutions to higher authorities. This view is in accordance with evidence provided by Abdullah et al., (2014), who found that a clear strategic direction in the organization –in terms of vision, objectives and goals – correlates with product innovation in the private sphere. In addition, according to Moon (1999), clarity in the mission of the organization promotes internal entrepreneurship, because it generates the flexibility necessary to take risks, as well as motivation and a better understanding of the organization's strategies.
Another factor that could influence the generation of innovation is the effect that a labor union can have on discouraging an innovative project that contrasts with their interests. This highlights the fact that innovative projects in work teams require not only the support of high-level authorities, but must also deal with other internal powers.
In team's own dynamics level, it was found that innovation drivers mentioned in the literature on ISP such as: teamwork, willingness to learn, employee empowerment, openness to team change, commitment to continuous improvement, and recognition and incentives for good work (Nijenhuis 2015, Alsos, Clausen, Isaksen, 2015, Lonti &Verma, 2003, Mulgan & Albury, 2003, Koch and Hauknes, 2005, Fernández and Moldogasiev 2012 ), are also found in the private sphere (Hogan and Coote, 2013, McLaughlin, Bessant and Smart, 2008, Liu, 2009, Dombrowski et al, 2007, Caldwell and O'Reilly III, 2003, Hulsheger, Anderson and Salgado, 2009 ).
However, this study offers interesting findings about how and why these factors promote innovation. In the public sector, teamwork is not only necessary to promote the communication of ideas that facilitate creativity and cooperation during the implementation of an innovation, but can also be decisive in determining if an innovation process that has already been implemented will work properly. With reference to the latter point, effective integration and trust between work teams are necessary to arrive at a consensus, and legitimize a possible innovative idea.
The relevance of promoting learning and the acquisition of knowledge is known to stimulate creativity and empowerment through innovation (Yu, Yu & Yu, 2013; Fernández & Moldogasiev, 2012; Fierro, Mercado & Cernas, 2013). According to Townsend (2013), the public sector must develop a culture of accumulation and communication of experiences to improve its capacity for innovation. However, both successful and unsuccessful experiences should be shared to build a better understanding of how innovation can be achieved. In the qualitative interviews carried out in this study, various means are proposed to promote institutional learning and the flow of knowledge. Some highlight the proactive search for information and knowledge as part of work dynamics, through consultation with experts, searching websites, and investigating what other institutions do, while others emphasize the importance of transmitting internal knowledge.
Empowerment helps to promote innovative behavior of coworkers (Bysted & Rosenberg Hansen, 2013; Lonti &Verma, 2003). To achieve this, it is necessary that the work dynamic gives team members autonomy in how to carry out their work, allows them to participate in decision-making, and gives them the confidence to express their ideas. With regard to this last point, it is notable that one interviewee stated that making fun of new ideas can cause people to avoid expressing them, thus becoming a possible inhibitor of innovation within the team.
Another underlaying factor is commitment to continuous improvement by team work. This could be encouraged by legitimizing values and norms that highlight the relevance of day-to-day improvement and promoting self-criticism as a mechanism for self-evaluation. Elements external to the work team can promote the development of such commitment. For example, instances such as institutional auditing or regulatory bodies can become sources external to the team that drive the development of continuous improvement.
Some authors have argued that the absence of economic incentives that motivate employees to become involved in innovation is a barrier to innovation in the public sector (Mulgan & Albury, 2003, Koch & Hauknes, 2005, Kovács, 2012). However, the comments of interviewees show that non-monetary incentives can also contribute to the involvement of coworkers. Verbal recognition of good work by the supervisor of the work team and/or their own colleagues is a mechanism that can encourage involvement.
Eliminating the time needed for daily tasks can remove an important inhibiting factor, allowing teams to dedicate themselves to the search for improvements and changes (Mulgan & Albury, 2003, Koch and Hauknes, 2005). According to the interviewees, staff members are frequently dedicated to "putting out fires", or routine work that leaves them less opportunities to think about what can be improved, or to spend time implementing an idea. One tool against this problem is the development of software and new systems that allow people to reduce the time they dedicate to operational tasks. Training on the effective use of time can also be useful in this regard. However, for this to take place, the organization must place a strong emphasis on the development of innovation.
Several authors have stated that the degree of specialization and knowledge of collaborators is an essential element for the development of innovation (Alsos et al, 2015, Jaskyte, 2011, Gurova & Kurilov, 2015). This is totally consistent with statements made by interviewees about the need to have highly trained professionals with extensive experience within the organization to detect feasible new ideas to be implemented and to overcome barriers encountered during the process of project execution.
At the individual level, another aspect highlighted by interviewees is the relevance of having young people in the team, because they are favorably disposed to change. This is supported by studies which have shown a positive association between the youth of members and the innovative behavior of the team (Hite, Williams, Hilton & Baugh, 2006; Young, Charns & Shortell et al., 2001). Although the youth of team members is an advantageous element for innovation, these sources also note that it is ideal to combine youth and experience in work teams, with youth providing openness and drive, experience providing discernment, and both providing knowledge.
In keeping with the literature, this study reveals that combining various skills and knowledge in a work team favors innovation. Diversity in teams helps in making better decisions in solving problems, because diversity of thought contributes to more realistic and complex analysis of contexts (Milliken & Martins, 1996). In addition, combining diverse knowledge and skills generates greater creativity and innovative ideas (Milliken & Martins, 1996; Shore et al., 2009). According to some interviewees in this study, diversity of professions and multidisciplinary work is one of the factors that has allowed them to innovate.
Finally, the results of this investigation suggest a link between the commitment of collaborators and positive attitudes. Having committed members who stimulate the willingness of others to become involved with innovation and assume the responsibilities required by a project was highly valued by interviewees. However, this commitment must be accompanied by a positive attitude to maintain perseverance and resilience in the face of difficulties. Even if there is creativity, without a positive attitude there will be no push towards implementation.
Lines for Future Research
Since this is a qualitative study, it would be valuable to continue with a quantitative study based on data from a sample of work teams in public organizations, which allows testing the effects of factors with possible positive and negative impacts on innovation suggested in this investigation. This would make it possible to concentrate efforts on providing explanatory models using the variables of different dimensions presented here to provide a generalizable systemic explanation of the phenomenon of innovation in work teams in the public sector.
Another interesting aspect to be investigated is the interrelationships between the four dimensions presented here, as the variables of one level can mediate the effect of the variables of another level, or there may be a circulating effect between variables at different levels. It is also necessary to determine the roles of each level and the different variables in the different stages of the process of innovation, that is, in the exploration of ideas, generation of ideas, promotion of ideas, and their implementation.
