Effect of lean six sigma on order fulfilment process: evidence from manufacturing companies in Gauteng, South Africa

Ethical Clearance reference No | 2021_FBMSREC 103A questionnaire was employed in this study to acquire data because it allowed the researcher to have a full understanding of the respondents who replied as it allowed enough time and space to respond and provide the respondents’ views. Additionally, this research method allowed researchers to collect data remotely. Accessing respondents in Gauteng Province would have been difficult for the researcher given the travel and other limits placed on people due to Covid-19 in South Africa at the time. The concerns or difficulties identified by the literature were considered while creating the questionnaire. Out of three hundred (300) participants, one hundred and fifty eight (158) workers answered the questionnaire. The workers were well versed in LSS requirements and the order fulfilment procedure.
