Despite this, several manufacturing companies, especially in developing countries are still confronting challenges related to inefficiencies in terms of their business processes. Against this background, this study examined the relationship between e-Business adoption and business efficiency in the manufacturing sector in Zimbabwe. A quantitative research approach was utilised to test the hypothesised relationships as conceptualised in the research model. A sample size of 118 manufacturing firms was obtained from a systematic random sample of 180 firms in the Confederation of Zimbabwe industries database. The results of the study show that the number of e-Business applications adopted by the firm and their usage rate have positive impact on business efficiency. However, the relationship between the spread of e-Business tools adopted and business efficiency was shown to be statistically insignificant. The study has important implications for manufacturing companies intending to adopt e-Business as a strategy of creating sustainable competitive advantage.
