ReviewA systematic assessment of supplier selection literature - State-of-the-art and future scope

- Large-scale longitudinal systematic literature review: 221 papers of major journals.
- Classification scheme structures research streams and contextual perspectives.
- Portfolio matrix technique applied to examine research streams in their life-cycle.
- Results reveal tremendous scientific progress, a trend predicted to continue.
- Carefully derived recommendations show potential avenues of future research.

With the growth in outsourcing in various sectors, the selection of the right suppliers is increasingly critical to a firm's business success. However, a thorough analysis of the extensive spectrum of supplier selection literature has not yet been performed. To address this gap, we conduct a comprehensive and systematic literature review. The purpose is to examine in detail the evolution of the extensive body of research, its research streams and areas for further research. We developed a classification framework that contains six streams of research derived from the extensive literature comprising both a quantitative and qualitative content analysis. To this end, this paper contributes a structured, large-scale and longitudinal review of 221 papers published in leading journals from 1990 to 2015 and carefully elaborated research recommendations to further advance supplier selection. Results reveal tremendous scientific progress in the last two decades, a trend predicted to continue. Moreover, the findings show that particular streams have been strongly accentuated whereas other important aspects lack examination. Research on mathematical approaches clearly dominates the body of supplier selection. Green and sustainable as well as strategy oriented supplier selection are at an early stage of the research cycle and represent upcoming streams. Contextual perspectives, such as behavioral aspects, theoretical foundation, or multi-period/ longitudinal settings also require further attention.
