Research onion diagram

This onion diagram example was designed on the base of figure "Research onion" in the article "The research methodology for the development of a kaizen costing framework suitable for indigenous construction firms in Lagos, Nigeria." by T. Omotayo and U. Kulatunga from the Association of Researchers in Construction Management (ARCOM) website. "The need for a cost management paradigm shift in the construction industry is imperative because of the prevailing challenges of managing construction cost during construction. Small and medium scale construction firms in Nigeria are faced with the challenges of competition from foreign firm, cost overrun, project delays and unsatisfied clients. This challenge may be handled with kaizen principles and kaizen costing. This paper utilized literatures related to research methodology in the built environment to create a research framework for the study. This focused on the research philosophical stands, approaches and strategy related to the built environment. The research onion model was adopted for the framework development and the sample size of two hundred and fifty (250) respondents was selected based on theoretical sampling for quantitative data collection using questionnaires."
