Discussion
The study was based on two key arguments. One, complexity and uncertainty are major attributes of today’s environment in which most businesses (HIEs inclusive) operate. Therefore, these organizations are expected to adapt and engaged in SI especially during intense and unforeseen situations (Hmieleski and Corbett, 2008). Two, HEIs are exposed to competition; hence, the only way they can respond to this is to ensure that the culture of the organization undergoes change, which will surely take time to be achieved. Therefore, we argued that SI and OC dimensions are positively related to performance. Also, OC dimensions moderates the relationship between SI and performance (Figure 2). From the proposed hypotheses, the finding establishes that SI is positively related to HEIs performance (H1). Consistent with H1, a positive and significant relationship was found between SI and HEIs performance. The finding is in line with previous studies (Arshad et al., 2015b; Bakar et al., 2015a; Gao et al., 2015) mostly conducted in the for profit sector. Putting resource base theory (Barney, 1986; Barney et al., 2001) into consideration indicates that leaders with improvisational ability are unique and source of competitive advantage in today’s environment. It also provides support for the need for management in non-profit organizations such as HEIs to recognize and appreciate improvisational behaviour especially during recruitment to ensure that only candidates with this ability are recognized during employment and leadership roles (Mohan et al., 2016; Ogbonna and Harris, 2000). In addition, the finding highlights the need for HEIs and other governmental organizations to seek for alternative to strategic planning in improvisation; thus, the ability to face and manage the current environmental pressure and unprecedented fast changes (Wind and Mahajan, 1997). Moreover, not-for-profit organizations should acknowledge the effect of SI behaviour across the institutions for performance and sustainability (Arshad et al., 2015a).
