October 2016 / The research project aimed at determining employees’ experiences of the application of the
flow efficiency methodology. The flow efficiency methodology was the selected
management methodology from the broader scope of process-focused methodologies. The
significance of the flow efficiency approach is that it’s an alternative approach to the
traditional management approach of optimising resource efficiency, but rather focuses on
improving the flow of the process in which the resources work. The research was conducted
in the context of the labour-intensive, South African manufacturing sector using a case study
approach. The purpose of the research was to understand front-line employees’ and
supervisors’ perceptions during the application of the flow efficiency approach. The assessed
perceptions came from four selected change factors that stemmed from the Lean change
iceberg model commonly found in literature. The motivation for research was two-fold: (1)
prior research of the flow efficiency methodology in the socio-technical environment focused
on operational improvement impact, and not on the impact on people; and (2), most research
of improvement approaches and methods in South Africa tended to focus on success factors
and pre-requisite maturity levels of various methods. The chosen flow efficiency approach
required no pre-requisite culture requirements. The researcher was of the view that gaining an
insight (through a case study) into employees’ perceptions of change factors during a flow
efficiency approach, could lead to benefits of development and empowerment of employees
and management in the labour-intensive, manufacturing sector of South Africa.
The case study selected was a flow efficiency-based, improvement initiative in a multinational
dairy plant in South Africa. The researcher used an unstructured, group-administered
questionnaire to assess operational and supervisory employees’ perceptions of the selected
change factors after process changes were made in the process where they work. The four
selected process-improvement change factors derived from the Lean change iceberg were:
Leadership Behaviour; Social System Change; Effectiveness of Change; and Employee
Involvement & Empowerment. Content validity was conducted with external and internal
experts to refine the questions and sequence of the questionnaire. A trained research assistant
facilitated the multiple questionnaire sessions. Thematic content analysis was used to
categorise participant’s responses into themes and sub-themes for each question. The
occurrence of themes and sub-themes per question was tallied up and discussed for
operational and supervisory employees with respect to the research objectives.
The research did not yield a broad-based view on the impact of the flow efficiency
management approach on employees’ perceptions in the greater industry context. However, it
did give an insight, through the case study, into some universally applicable perceptions of
changes experienced by South African, front-line and supervisory employees when the flow
efficiency management approach was used. Perceptions of: leadership commitment and
coaching, improved teamwork, simplification of jobs, improved flow, and improvements in
individual performance, and employee empowerment were prevalent perceptions felt by most
employees at both levels. / MT2017
