<p><strong>Background:</strong> Innovation is recognised as one of the most important determinant of organisational performance. Yet, the results of studies that investigate the relationship between innovation and organisational performance are inconclusive. The inconsistency has been attributed to a number of factors, which include, among others, the measures used to evaluate organisational performance.</p><p><strong>Aim:</strong> This study was set out to identify, categorise and critically analyse the instruments used to assess organisational performance when investigating the relationship between innovation and organisational performance.</p><p><strong>Setting:</strong> The study focuses on all scientific publications reporting on organisational performance, inclusive of both financial and non-financial indicators of performance, and are not limited to any specific country or industry.</p><p><strong>Methods:</strong> The systematic literature review methodology was used to identify studies which investigated the relationship between innovation and organisational performance. Once identified, articles were analysed on the way organisational performance was measured. Classification was done with reference to financial and non-financial indicators, accounting and market-based, as well as objective and subjective measures.</p><p><strong>Results:</strong> The findings show that profitability, sales growth and return on assets (ROA) are the most preferred accounting-based financial measures of organisation performance. In addition, Tobin’s Q was found to be the most favoured market-based financial measure of organisational performance. The study further reveals that market share, customer satisfaction and productivity are the most popular non-financial-based measures of organisational performance.</p><p><strong>Conclusion:</strong> The use of measures of organisational performance is often left to the discussion of the researcher, which is not implicitly wrong, but does little to contribute to the body of knowledge on this important topic. Researchers are firstly urged to clearly define which aspects of organisational performance they intend to study, secondly to use established instruments or often used indicators of organisational performance, and thirdly to combine both objective and subjective measures of organisational performance. This would allow for researchers to build on the work of other and strengthen the body of knowledge in this area.</p>
The study on which this paper is based examined the effect of transformational and transactional leadership styles as well as the effect of each component of transformational and transactional leadership on innovative behaviour. A sample of 3 180 respondents from 52 South African companies participated in this research. Two main hypotheses and six sub-hypotheses were tested using multiple regression analysis with and without interaction terms. The results indicate that it is useful to utilise both transformational and transactional leadership styles to enhance employees' innovative behaviour. The study substantiated the expected positive relationship between transformational and transactional leadership style and innovative behaviour. Furthermore, the results showed that amongst the components of these leadership styles, inspirational motivation, intellectual stimulation and contingent reward positively influence innovative behaviour. The results showed no relationship between individual consideration, management-by-exception and innovative behaviour. Contrary to expectations, the results revealed a negative relationship between idealised influence and innovative behaviour. Recommendations and suggestions for further research are provided.
The purpose of this paper is to examine the nature of the relationship between leadership styles, organisational climate, innovation and organisational performance. The study was quantitative in nature using questionnaires submitted by 231 participants from various companies in South Africa. The statistical analysis was based on Structural Equation Modelling (SEM) using the path analysis. The results from SEM reveal that transformational leadership style influences the climate for innovation and organisational performance directly and innovation indirectly. Similarly, a direct relationship between transactional leadership style and organisational performance was found, but no relationship was found between transactional leadership style and innovation. The findings assist managers to better understand which leadership style to adopt when the aim is to increase organisational performance using innovation as an enabler. This is the first study that investigated the nature of the relationship between leadership styles, organisational climate, innovation and organisational performance taking into account the nature of innovation (i.e., incremental and radical) and the stage at which innovation is operating in the innovation process.
This paper is an attempt to consolidate the published scientific knowledge about the impact of leadership styles on the relationship between innovation and organisational performance. Concepts, statements and conceptual frameworks were used as structure to analyse the body of scientific knowledge. After consulting 31 major research databases using the systematic literature review methodology, only seven journals articles that examined the link between leadership, innovation and organisational performance were identified. The synthesis of the journal articles revealed (a) that consensus exists among researchers as far as the relevant concepts are concerned; (b) that most agree on the definition of leadership and innovation but that a uniform understanding of what constitutes organisational performance is lacking; and (c) that conceptual models are too simplistic and do not consider mediator variables or multiple financial criteria measures. The findings further reveal that innovation is significantly and positively related to superior organisational performance, and that, although transformational leadership style is significantly and positively related to innovation, transactional leadership style is more appropriate when the aim is to instil a culture of innovation. Transformational leadership style, by contrast, is mostly associated with organisational performance. In addition, the findings further reveal that none of the studies investigate the mediating effect of the nature of innovation (incremental and radical) on the relationship between leadership and organisational performance, and that none of the studies use the objective measures of financial performance such as ROA, ROE, price/earnings (P/E) and Tobin's Q calculated from annual financial reports.
This study investigated the mediating effect of organizational climate on the relationship between transformational and transactional leadership styles on innovative behaviour. 1 The effect of each component of transformational and transactional leadership styles on innovative behaviour was also investigated. A sample of 3,180 respondents from 52 South African companies participated in this research. Four main hypotheses and six sub-hypotheses were tested using multiple regression analysis. The results revealed that indeed organizational climate mediates the relationship between transformational and transactional leadership styles on innovative behaviour as well as their components. The study substantiated the expected positive relationship between transformational leadership style and innovative behaviour. Furthermore, the results showed that among the components of transformational leadership styles, inspirational motivation and intellectual stimulation influence innovative behaviour positively. This study showed that in an environment conducive to innovation, the transactional leadership style has no influence in enhancing employees' innovative behaviour. This study provided new insight into the nature of the relationship between leadership styles, organizational climates and innovative behaviour.
