Strategic Flexibility and the Effectiveness of Quality Management Systems: Evidence from Medium-Sized Manufacturing Firms in Nairobi County, Kenya

Abstract

This study investigated the effect of Strategic Flexibility on the effectiveness of Quality Management Systems (QMS) in medium-sized manufacturing firms in Nairobi County, Kenya. Guided by Dynamic Capability Theory and adopting a pragmatist mixed-methods design, data were collected from 221 respondents drawn through stratified random sampling from 496 ISO 9001:2015 certified firms. Quantitative data from quality, operations, and technical managers were analysed using SPSS version 27, while qualitative insights from 14 purposively selected senior managers were analysed using NVivo 14 through thematic coding. The two data strands were integrated sequentially, with qualitative findings used to triangulate and provide a deeper contextual explanation of the statistical results. Results show that Strategic Flexibility, reflected in market responsiveness, financial and HR flexibility, cross-functional collaboration, contingency planning, product diversification, strategic foresight, and organisational resilience, was a strong predictor of QMS effectiveness, explaining 32.4% of the variance (R² = 0.324, β = 0.276, p < 0.001). Qualitative evidence further revealed that flexible firms experienced better process consistency, reduced inefficiencies, and improved product quality. The study concludes that Strategic Flexibility is a critical dynamic capability that enhances QMS effectiveness by supporting agile resource allocation, proactive risk mitigation, and continuous improvement. Strengthening organisational flexibility mechanisms is recommended to maximise the benefits of ISO 9001:2015 and improve manufacturing performance.
