Abstract

This paper presents an overview of Design-Expert, a statistical experimental design tool, in optimizing chemical engineering research and development. A mixed-method approach is adopted in the study by using quantitative literature findings of diverse experimental studies incorporating the use of Design-Expert and qualitative findings stemming from a focus group study with four cross-institutional chemical engineering research supervisors. While the quantitative literature studies demonstrate the effectiveness and capabilities of Design-Expert across multiple fields of study, the qualitative study is based on the perspectives, experiences and recommendations of the research supervisors concerning Design-Expert. The qualitative study was structured with five main sections: the integration of Design-Expert into research activities, the effectiveness and outcomes of Design-Expert, management of academic priorities incorporating the use of Design-Expert, research skills and development concerning the training of postgraduate students in applying Design-Expert into their research, and the broader impacts and collaborations facilitated by Design-Expert. Overall, the findings indicate substantial positive findings concerning the productivity and quality of research outcomes incorporating the use of Design-Expert.
