Background: As the use of mobile computing devices such as smartphones increase in developing countries, some employees in organisations prefer using their privately owned mobile devices for work purposes by following the Bring Your Own Device (BYOD) practice. However, the actual factors that influence the adoption of this practice are limited.

Aim: This study aimed to investigate the factors that positively influence the employee’s behavioural intention to adopt the BYOD practice in organisations.

Setting: The focus of the study is workers in various industries in South Africa.

Method: A model is proposed which extends components of the Unified Theory of Acceptance and the Use of Technology (UTAUT) model by certain elements of the ISO/IEC 27001 security standard and an organisational factor. It is a quantitative study. Through a snowball method, a sample of 130 South African workers participated in the study by completing an electronic survey where 106 valid responses were received.

Results: The data analysis was conducted through the SPSS data analysis tool. The results revealed that performance expectancy, effort expectancy, awareness and training, and policy existence positively influence the behavioural intention to adopt the BYOD Practice.

Conclusion: The outcome of this study will benefit practitioners considering the implementation of BYOD and also researchers seeking to expand the scope of existing technology adoption frameworks.
