Abstract:
This article presents a demonstration of how gemba kaizen, which is continuous
improvement in the workplace, can be implemented using business process
modelling and notation (BPMN). The scope of the study is construction businesses in
Nigeria. In developing the BPMN model for construction businesses in Nigeria, the
modus operandi regarding decision making and managing challenges which may be
transferred to the cost planning was identified. The mixed-method approach was used
to develop this model from the qualitative and quantitative findings. The survey
strategy was employed for the analysis, covering eleven interviews and one hundred
and thirty-five questionnaires from contractorsand cost and project managers in
small- and medium-scale companies in Lagos, Nigeria. NVIVO 10 and descriptive
statistics were used to assess the results. The findings of the study focused on the
perception towards change, post-project reviews, openness to new ideas, and
innovation. The study observed post-project reviews as the only significant indicator
of continuous improvement in Nigerian small- and medium-scale construction
companies. This result is not enough to indicate that there is continuous improvement.
Therefore, the model design focused on continuous improvement activities for the
companies. The creation of a BPM model elucidated the continuous improvement
functions, stages and processes. This study may be implemented in construction
companies in developing economies for improving the competitive advantage of
small- and medium-scale construction companies.
