1. Introduction
Small and medium enterprises (SMEs) need to have a reward system that supports innovation. Knowledgeable intrapreneurs are important for this cause, though they are likely to put pressure on limited resources of SMEs. In this context, Jarboe and Alliance; Attar, Kang and Sohaib [
1,
2] confirm that when employees move, formal or informal knowledge becomes mobile and immobile at the same time. Closely related to this, Lewis [
3] reiterates that entrepreneurs need creativity and updated skills to improve performance. According to Nikolov and Urban [
4], the decisions of employees to participate in corporate entrepreneurship initiatives is associated with a variety of available rewards, such as opportunities for future growth, financial incentives, sense of achievement from completing challenging and interesting work as well as participation or autonomy in decision-making.
The SME sector has become an essential instrument that economies of the developed, developing and underdeveloped countries use to address socio-economic policies as well as industrial activities [
5]. However, generating employment, contributing to innovation and promoting inclusive growth vary widely across firms, countries and sectors. For example, in USA and Japan (developed countries), SMEs are seen as an industrial base and backbone of the service sector supporting manufacturing activities. Similarly, in India and Indonesia (developing countries), SMEs contribute to social and economic development such as employment creation [
5]. In the context of South Africa, a developing economy, which the Global Entrepreneurship Monitor South Africa Report [
6] refers to as “an efficiency-driven economy rather than an innovation-driven economy”, the sector addresses inequality, unemployment and poverty. SMEs contribute approximately 35% to the country’s gross domestic product (GDP) [
7]. The small business sector continued to show a positive employment growth in the past decade in contrast to the job losses in large and public enterprise sectors [
8]. The SME sector therefore, plays a major role in the growth and competitiveness of the South African economy [
9], as in other developing economies. However, being an “efficiency driven” economy poses a threat to innovation performance of SMEs because such an economy is “resource process driven” as opposed to being “innovation driven”. It therefore becomes more difficult to realize “innovation performance” in the former economic architype. In an innovation-driven economy, most organisations produce products with well-designed processes and launch them as new to the market. Mohanty [
10] points to the challenges of inadequate resources and lack of reward to crowdsource intrapreneurial initiatives to facilitate innovation processes and improve performance of firms. Although resource constraints and the need for innovation characterise the SMEs sector, Azami [
11] indicates that firms’ innovativeness is likely to be influenced by organisational resources that are mostly linked to its size. Aptly, it remains complex for resource constrained SMEs to reward employees to enhance innovation, especially in a resource driven economy as South Africa. Fini, Grimaldi, Marzocchi, and Sobrero [
12] reiterate the complexity of resource constrained environments for the application of corporate entrepreneurship principles to SMEs. Although rewards seem to enhance employees’ propensity to take risk associated with intrapreneurship [
4], it is not evident whether the way employees are rewarded makes a difference in innovation performance of SMEs. Thus, it is critical for SMEs in the context of the current high competitiveness and the challenges posed by the fourth industrial revolution to prioritise innovation. The question becomes, how significant is the influence of rewards on the innovation performance of manufacturing SMEs in South Africa?
SMEs need to acquire knowledgeable employees to access critical knowledge, and to be able to absorb capacity [
13]. This paper investigates the types of available rewards in SMEs and establishes whether rewarding intrapreneurs is a catalyst for innovation performance of these firms. Previous studies on the effects of rewards on innovation, for example, in the South African context, indicate that it is critical for businesses to nurture intrapreneurship [
4,
14,
15]. These studies did not focus on small businesses, which this study does. In the same context, studies in India and Turkey (other emerging economies) show that intrapreneurial behaviour in SMEs improves when employees receive institutional rewards [
16,
17]. In a European context, Matzler, Schwarz, Deutinger and Harms [
18] indicate that, in the context of innovation management, rewarding intellectual curiosity and taking chances, may be more effective than an inflexible reward scheme. According to the Global Competitiveness Report, India is a “factor driven economy” while Turkey is classified as a country in “transition” to innovation-based economy [
19,
20,
21]. The above-mentioned studies do not look at how the different types of rewards individually influence the innovation performance of SMEs. In addition, previous studies essentially direct their focus on large organisations especially as a reward is seen as a corporate entrepreneurship factor [
22]. This study seeks to establish the influence of various types of rewards on innovation performance in the context of a resource constrained environment of SMEs. The other importance of this study is that it is carried out in the backdrop of an “efficiency driven” economy in which “innovation performance” is least expected.
The next sections review relevant literature on innovation performance and rewards in the SME context, and then the research method used is justified before presenting the study results and discussion. Conclusions and recommendations are provided last.
4. Results
It was crucial to investigate the small medium enterprises’ capacity to pay a variety of rewards and to test how various rewards contribute to innovation performance. The study first sought to establish/confirm the incentives offered by SMEs as well as their distribution.
Figure 1 shows the percentages of firms that offer a particular incentive.
Besides a regular salary that was awarded by 99.5% of SMEs, the top five other types of rewards paid by SMEs are, promotion within the organisation (37.1%), regular salary increases (31.7%), monetary bonus (29%), sponsoring special training for new skills (26.7%) and reward with time off (22.6%). It can be seen that these percentages are very low. Some rewards are paid by as low as less than 10% of SMEs. Overall performance such as growth, profitability and competitiveness is likely to be negatively affected if certain incentives are not paid to employees for them to be innovative. The results indicate that about 27% of SMEs sponsor employees for a special training to learn new skills as a reward mechanism. This shows the lack of opportunity for development of employees in SMEs, although this reward constitutes an investment in the sense that skills learned are likely to be used to improve innovation performance. This is because Lewis [
3] points out that the entrepreneur needs creativity and updated skills to improve business performance. Furthermore, promotion and possible salary increases are found to be implemented by less than 40% of SMEs, which is relatively low. Another important reward that is paid by only 11% of SMEs is scholarship to employees’ dependents. This social intervention might allow skilled personnel to strengthen their attachment to SMEs and compensate for the lack of salary increases and promotion. The influence of available rewards on innovation performance of SMEs was tested using regression analysis. Each reward was tested against the IP elements; product (HO
1), process (HO
2), position (HO
3) and paradigm (HO
4). The results are shown in
Table 2,
Table 3,
Table 4,
Table 5,
Table 6,
Table 7,
Table 8 and
Table 9.
Results from
Table 2 show that Product Innovation performance is predicted by R-square of 0.243. This means that a one-unit increase in rewards predicts a 0.243% of product innovation. This can be in any of the reward elements mentioned. It can therefore be concluded that Rewards significantly influence Product Innovation performance. Hypothesis HO
1 is therefore accepted.
The ANOVA analysis (
Table 2) shows that there is a significant difference between the rewards and product innovation performance as shown by an alpha value of 0.00. To show which reward element have a significant influence on product innovation, coefficient results are shown in
Table 3.
The influence of rewards on product innovation performance was evaluated against the predictors using multiple linear regression analysis. The model is best summarised by the following equation:
Y1: Product innovation performance
a: Intercept
X1: regular salary pay
X2: promotion within the organisation
X3: equity /profit share to encourage participation
X4: monetary bonus rewards
X5: payment for suggestions that lead to financial benefits from innovations
X6: recognition of achievement awards
X7: commission on new products sold
X8: team financial incentives for meeting or exceeding innovation objectives
X9: company sponsored holiday
X10: regular salary increases
X11: remuneration depending on number of units produced
X12: reward with time off
X13: company sponsored lunch
X14: scholarship to employees’ dependents
X15: receive company shopping vouchers
X16: receive gifts for achievement
X17: sponsoring special training for new skills
ϵ: Residual (error)
The results, standardized coefficient values (
Table 3) show that X.1, X.3, X.5, X.7, X.8, X.9, X.10, X.14, X.15, X.16, and X.17 all have a negative influence on product innovation performance and on the other hand, X2, X4, X6, X.11, X.12, X.13 have positive influences on Product IP. This, imply that an increase in a unit of the reward element, result in a decrease (if the coefficient value is negative) or an increase (if the value is positive) of the particular innovation performance by the value indicated. For example, an increase by one unit of X.2 (promotion within the organisation) will result in an increase of 0.166 in Product IP while a similar increase in one element in X.3 equity /profit share, would decrease the Product IP by a value of 0.169. In addition, promotion within the organisation (X.2), and Payment as a result of suggestions that lead to financial benefits from innovations (X.5) significantly influence IP as shown by alpha values, 0.034 and, 0.001 respectively. It should be noted that reward X.2 has a positive influence on Product IP while X.5 has a negative influence on product IP. This means that an increase by one unit in X.2 will result in an increase in IP by 0.166 while a one-unit increase in X.5 will decrease product IP by −0.257. The effect is significant, positive on the former, significant and negative on the latter.
The analysis presented above will not be repeated for each of the remaining three innovation performance elements, product, process and paradigm. Brief explanations will be provided where deemed necessary. In the regression analysis, Y2, Y3 and Y4 will represent each of the innovation performances, process, position and paradigm respectively.
4.1. Rewards and Process Innovation Performance
The results on the influence of rewards and process innovation are presented in
Table 4 and
Table 5.
Results from
Table 4 show that Process Innovation Performance is predicted by R-square of 0.260. This means that a one-unit increase in rewards predicts 0.260 of Process IP. From the model summary, it can be concluded that, Rewards significantly influence Process Innovation performance. Hypothesis HO
2 is supported.
The ANOVA analysis shows that there is a significant difference between the rewards and process innovation as shown by an alpha value of 0.00. To show which reward element have a significant influence on process innovation, coefficient results are shown in
Table 5.
Standardized coefficient values (
Table 5) show that X.1, X.2, X.3, X.5, X.7, X.8, X.9, X.10, X.11, X.14, X.16, X.17 all have a negative influence on process innovation performance and on the other hand, X4, X6, X.12, X.13, X.15 have positive influences on Process IP. This, imply that an increase in a unit of the reward element, result in a decrease (if the coefficient value is negative) or an increase (if the value is positive) of the particular innovation performance by the value indicated. Only the reward,
Scholarship to employees’ dependents promotion within the organisation (X.14), significantly influence Process IP as shown by alpha values, 0.009. The influence is however negative.
4.2. Rewards and Position Innovation
The results for the influence of the different rewards and position innovation performance are shown in
Table 6 and
Table 7. These results show that Rewards have a significant influence on Position Innovation performance. Hypothesis HO
3 is therefore accepted.
The ANOVA analysis (
Table 6) shows that there is a significant difference between the rewards and position innovation performance as shown by an alpha value of 0.00. The coefficient for rewards and Position Innovation are shown in
Table 7.
The standardized coefficient values (
Table 7) show that X.3, X.5, X.7, X.8, X.9, X.10, X.11, X.16, and X.17 all have a negative influence on Position Innovation Performance while the remainder are positive. Only Monetary bonus rewards (X.4) and Team financial incentives for meeting or exceeding innovation objectives (X.8) are significant at alphas of 0.005 and 0.001 respectively. X.4 has a negative significant influence while X.8′s influence is significant and positive.
4.3. Rewards and Paradigm Innovation
Results for paradigm IP are shown in
Table 8 and
Table 9 and brief discussions are provided. The Hypothesis HO
4 is accepted. Rewards significantly influence Paradigm Innovation performance.
The standardized coefficient values (
Table 9) show that X.3, X.4, X.5, X.7, X.8, X.14, X.15, X.16, and X.17 all have a negative influence on paradigm innovation performance and the remainder have a positive influence. Only rewards; Promotion within the organisation (X.2), Payment because of suggestions that lead to financial benefits from innovations (X.5), Commission on new products sold (X.7) and Team financial incentives for meeting or exceeding innovation objectives (X.8) significantly influence paradigm innovation. Of these four, only X.2 has a positive significant influence and the remainder negative.
5. Discussion of Results
The study objective was to establish if the rewards offered to intrapreneurs significantly contribute to the innovation performance of manufacturing SMEs. The hypothesis (HO) that stated that; Rewards significantly influence the innovation performance of SMEs is supported. Results show that the rewards that have a positive and significant influence on IP are offered by a few of the SMEs. Different rewards also significantly influence different aspects of IP. Promotion within the organisation (X.2) has a positive and significant influence on Product and Paradigm IPs, while, Rewards payment for suggestions that lead to financial benefits from innovations (X.5), is significant but with a negative influence on the same elements. Team financial incentives for meeting or exceeding innovation objectives (X.8) is significant and negative in Position and Paradigm IPs. Scholarship to employees’ dependents (X.14), has a significant and negative effect on Process IP; Monetary bonus rewards (X.4), significantly and positively influences Position IP and Commission on new products sold (X.7) has a significant and negative influence on Paradigm IP.
It is important to note that X.2 and X.4 benefits (which have a positive influence) are offered by 37.1% and 29% of the SMEs respectively. This is the second and third most common reward offered besides the regular salary, which is offered by 99% of the SMEs. The outcome is very encouraging because the two most popular / common rewards also have a significant positive influence. It should also be noted that these two rewards significantly influence three IP elements, save for Process IP. Those SMEs currently offering these two rewards should continue to do so and those not currently offering them, should be encouraged to do so. The importance of these two rewards are confirmed [
2], as being part of high performance work systems (HPWS) that enhance employee performance. Rewards X.5, X7, X.8 and X.14 that have a significant but negative influence, are relatively common, since they are offered by 12.2%, 18.1%, 13.1% and 10.9 % of the SMEs respectively (
Figure 1). The term “relatively” was used given that there are lower scores, such as 8.6% (X 2) and 3.6% as the lowest (
Figure 1). X.5 features in both Product and Paradigm IPs while X.8 appears in Position and Paradigm IPs. X.14 has a significant and negative influence on Process IP. Given the relatively high prevalence of X.8 and its significant and negative effect on IP, it is suggested that its offering be reconsidered and be further probed. The question would be whether “individual” as opposed to “team”,
financial incentives for meeting or exceeding innovation objectives, would be more preferable and therefore have a positive influence. Alternatively, would rewarding both the individual as well as the group effort result in a significant positive effect? Besides “scholarship to employee’s dependents” (X.14), the other rewards, which are significant and negative, tend to be “after the act” incentives. This may explain the negative effect. For example, X.8, meeting and exceeding innovation objectives, commission on new products sold (X.7) and payment to suggestions that would have led to innovations (X.5), would be paid after the IP has been realised. This may imply that incentives that encourage participation in idea generation (crowdsourcing of ideas) whether these ideas are successfully converted to products and services or not, should be encouraged.
The crowdsourcing of ideas is important in innovation performance. The more people actively engage in innovation, the more likely positive results can be achieved. The adoption of multiple incentives by firms can be used to derive enhanced productivity, [
69] such as to encourage or promote innovation performance. Different contexts or rewards do not trigger underlying employee mental processes the same and so provide intrapreneurial actions differently [
70]. Solheim and Herstad; Murimbika and Urban [
71,
72] confirm that innovation performance can be achieved when organisations urge voluntary intrapreneurial inclinations through appropriate rewards. Rewards that characterise, high performance work practices (HPWP) include, recognition, training and continuous development, performance based pay and job security [
73]. The findings corroborate Eisenberger and Byron’s [
74] earlier findings that rewards increase creativity in an organisation and that creative performance is based on an individual’s responses to repeatedly being rewarded. In addition, innovation capability would not be possible if staff is not adequately skilled and motivated to adopt them, through provision of of discretionary time and participation in decision-making [
73]. Creativity is believed to be the source of innovation. The study also concurs with Leavitt’s [
54] findings that consistent recognition of those who contribute ideas, knowledge, and time has a positive influence on crowdsourcing innovation outputs. Financial incentives are proven to drive innovations in SMEs. According to Leavitt; Nacinovic et al., [
27,
54] senior management should recognise innovative teams and champions, and individual members for their contributions to the overall crowdsourcing effort.
Results in
Figure 1 show that only 29% of SMEs provide monetary bonus incentives, which is a positive practice among SMEs. This is likely to affect the employees’ commitment to innovation and the overall innovation performance of the SMEs sector. De Jong, and Hartog [
68] confirm that the availability of reward and resources is an important factor that could encourage individuals to act entrepreneurially and achieve innovation within a firm. In addition, Zheng, Wu, and Xie [
75] observe that a transactional leadership style adopting contingent rewards is positively associated with the innovation performance position. In line with the findings of this study, Maier and Zenovia [
76] ascertain that innovation is more difficult to find in an existing SME as resources are linked to rewards for success. It can be argued that the reward system must be aligned with an innovation strategy of manufacturing SMEs. As pointed out by Marx, Soares and Barros [
77] a reward system, designed strategically should link rewards directly to individual employees’ attention and effort. Crowdsourcing for innovation performance is individually based, but organisationally driven through appropriate rewards. SMEs should therefore be aware of this strategic link if they want to enhance their innovation performance.
Reward is proven to motivate entrepreneurial behaviour [
40]. With appropriate incentives, employees’ willingness to assume intrapreneurial risk is likely to be enhanced. Rewards can therefore be used to crowdsource innovation performance. Considering the limited diversity of rewards to support innovation, the study further concurs with Azami’s [
11] findings that recognise that intrapreneurial success is very rare in SMEs. Azami [
11] states that no company provided payment in advance, for what an intrapreneur may accomplish, but firms put high expectations that employees have to get involved and take risks. Although, Ireland et al., [
43] find that rewards constitute an opportunity for employees to act intrapreneurially, Kuratko [
78] asserts that a reward system has to have an explicit element of recognition given to people who pursue innovative opportunities.
Reward is supposed to be a reinforcement mechanism to motivate employees to engage in innovative behaviour [
79]. The income received by employees is expected to positively affect their involvement in entrepreneurial activities [
80]. In this context, it can be argued that the attachment to organisations by an educated and skilled workforce to support innovation could possibly be justified by employees’ expectation of various types of rewards. The results confirm that manufacturing SMEs have done little in terms of aligning innovation objectives and rewards. In summary, SMEs are inclined to paying their employees a regular salary, but little has been done to offer other forms of rewards and promote innovation through a reward system. The next section will conclude the findings of the study and provide recommendations.
6. Conclusions and Recommendations
The empirical findings prove that some rewards have a more significant influence than others do on innovation performance. Some rewards have a positive influence while others’ influence is negative. However, the lack of diversity in rewards paid by SMEs may hinder their innovation success. The study found that less than 37.1% of SMEs paid any other reward besides a regular salary. The study therefore concludes that efforts that may lead to innovation performance are overlooked in SMEs. Love, and Roper [
81] opine that innovation poses skills and people management challenges that necessitates a new ecosystem of skills to retain skilled and entrepreneurial people in the organisation. Although, the reward of employees through promotion (37.1%) and provision of salary increases (31.7%) and awarding of bonuses (29%) are relatively the 3 highest rewards offered (other than regular salary) these are still low adoption rates and reaffirms the SMEs resource constraint and lack of opportunity for employees’ growth.
Manufacturing SMEs have done little in terms of aligning innovation objectives and rewarding their members. It can also be interpreted that SMEs are inclined to paying their employees a regular salary, and may consider promotion and pay monetary bonuses, but do not promote innovation through a reward system. This study concurs with, Manso [
39] that owner-managers should be keen to understand that recognition of employees success allows SMEs to record high innovation performance.
The study recommends owner-managers to consider diversifying rewards, despite the limited resources. They should specifically adopt those rewards that were found to positively and significantly influence IP and at the same time attempt to minimise the negative effect of the rewards found to be significant but negative. Owner-managers should stimulate employees to generate as many innovative ideas (crowdsourcing) as possible through a system rewarding suggestions that lead to innovations. The rewards, which have shown a positive influence on IP (though the influence may not be significant), should all be considered. The study also recommends owner-mangers to provide rewards that are affordable due to resource constraints. Strategically, SMEs should align the business reward systems with the innovation performance goals of the organisation. This implies the efficient use of limited resources to capitalise on activities that promote and sustain innovations. Furthermore, owner-managers should develop an individual oriented and a team-oriented reward system. This would counter the possible negative influence of team-based rewards, found to significantly and negatively affect IP. Representation from different sections of the business must be engaged to develop guidelines and suggestions to encourage crowdsourcing innovations.
Finally, owner-managers should support the growth and development of their businesses through redefining new approaches about innovations as an imperative for sustainability and competitiveness; that is, maintaining continuous improvement of their business models. This should be done by creating a high performance knowledge sharing culture (HPKC) which according to Rehman et al., [
63] p. 4 is a “Knowledge-enabled collaborative work culture derived by a skilled, self-directed and engaged workforce that shares collective vision and exerts discretionary efforts to create a highly productive knowledge exchange system…”. This type of culture will ensure social and environmental sustainability due to its proactive and adaptive capabilities DNA. Ali, Sun and Ali [
82] support this thinking.
The application of these recommendations is likely to be more effective where the SME has innovations performance as its strategic posture. This is characterised by the generation of ideas and a regular conversion of these into new products and services. This entrepreneurial culture should drive the entity. An appropriate reward system (which satisfactorily rewards both idea generation and conversion) needs to be in place. The continual skilling of employees as well as retaining the skills and the people is critical. Though high salaries may not be available to reward employees (as in resource rich big companies) alternative reward systems should be considered.
South Africa’s low rank among the more innovative countries necessitates further research into the innovation performance of small and large companies. Furthermore, it is crucial to undertake a longitudinal study in order to observe changes in innovation performance based on changes in reward offerings. It might also be necessary to establish which combinations of rewards will likely result in higher innovation performance. This study looked at the types of rewards offered by different SMEs and if this will significantly lead to innovation performance. It did not assess or identify from the employees; which rewards would make them contribute more to innovation activities. These issues could be undertaken in future studies. The study was limited to manufacturing SMEs in Kwa-Zulu Natal region of South Africa and data collected at a specific time. The results may not be generalised to other regions or provinces where structural factors may be different. For instance, the prevailing economic environment such as the low growth may affect SMEs’ capacity to invest in research and development or other innovation programmes or the rewards offered. Lastly, only the manufacturing sector was included, and different sectors such as retail and construction may reach different conclusions.
