Abstract
In South Africa’s highly competitive economy, organisations must adopt effective strategies to enhance performance and remain sustainable. Despite, employing operational improvement strategies, including Lean Six Sigma (LSS), many firms struggle to achieve long-term financial success. This study investigates an Operational Sustainability Model to improve financial performance of XYZ (Pty) Ltd, a trading company that adopted LSS but experienced stagnant financial growth.
This study seeks to assess the impact of an operational sustainability model designed to address these challenges. The model incorporates key inputs-implementation planning, employee training, leadership commitment, and incentive schemes-to drive outputs such as sustainable methodology adoption, cost reduction, efficiency improvement, and enhanced financial performance.
A positivist paradigm and quantitative approach were adopted, with data collected through web-based surveys distributed to employees using systematic sampling. Statistical analysis, including descriptive and inferential methods, was applied to interpret the data, while ethical principles ensured transparency and participant protection.
Findings revealed that sustainable financial performance is strengthened through: (i) the strategic integration of sustainability into business planning, (ii) investment in employee training and development, (iii) leadership commitment to sustainability, and (iv) incentive schemes that motivate employees toward sustainable practices. This study’s results offer valuable impact to the existing literature on improvement frameworks by illustrating how the integration of Lean Six Sigma (LSS) with sustainability-oriented strategies can strengthen organisational resilience and improve financial performance in competitive environments.
