Micro and small enterprise (MSE) owners in Kenya are faced with a myriad of constraints that affect their survival for longer than the first 5 years. Owners of MSEs who are unable to identify and implement strategies may not succeed in sustaining their businesses. The purpose of this multiple case study was to explore strategies owners of MSEs in Nairobi, Kenya, used to sustain their businesses for longer than 5 years. The conceptual framework for the study was the theory of constraints. Data were collected from 4 purposefully selected MSE owners in Nairobi, Kenya, through face-to-face, semistructured interviews, and review of field notes and company documents. Using thematic data analysis, the major themes that emerged were customer service, access to capital, and nearness to market. The implications of this study for positive social change include strategies for MSE owners to generate stable income for employees, new employment opportunities for job seekers, improved standards of healthcare and education for the community, and a positive lifestyle for the residents of Kenya.
