This research aimed to explore the influence of implemented innovative managerial practices, processes, techniques and structures on the sustainable performance of a Small and Medium Enterprise (SME) in South Africa. An exploratory research method was utilised to gain insights into management innovation practices in a knowledge-intensive company as the case study organisation. Findings from this exploratory study indicated that the combination of key management innovation aspects such as leveraging collective knowledge of employees, valuing stakeholder relationships and participative decision-making processes contribute to organisational performance. The organisational community pursues a common purpose and stimulates constructive debate in and between self-managing teams, ultimately leading to an environment that supports innovation and the sustainable positive performance of the case study SME, inter alia based on the yearly growth of the net asset value (NAV) for the past ten years.
