PurposeThis paper aims to examine the current status and trends in circular economy (CE) research. The state of CE research is assessed by critically examining the field by considering diverse dimensions.Design/methodology/approachThe systematic literature review (SLR) of CE research articles is analyzed using the content analysis methodology. The articles are selected from the Scopus database containing the keyword “Circular economy” in its title, abstract and keywords. In total, 587 research articles published on CE in various reputed peer-reviewed journals over 15 years (2005–2020) are selected for review.FindingsThe research in the domain of CE is in the beginning phase. It has numerous quantitative modeling opportunities, value creation and propositions aspects and application in real-life case problems. One of the significant findings is that the CE research field is more inclined toward the implication of the empirical qualitative research. The identified research gaps and future opportunities could provide further direction to broaden CE research.Research limitations/implicationsThe review focuses on publications published in peer-reviewed journals in the English language only. It restricts the recognition of relevant articles published in conference proceedings and languages other than English.Originality/valueThis research study will provide a deeper understanding of CE research's existing status and highlights the research trends, gap and its applicability in real-life case problems and setting up future research directions in the CE field.

Purpose Outsourcing is a crucial tool for an organization to focus on its core business operations. The purpose of this study is to find critical success factors (CSFs) of outsourcing and to prioritize the performance outcomes of outsourcing because of the adoption of its CSFs. Design/methodology/approach This research proposes the hybrid framework of fuzzy Delphi, fuzzy analytic hierarchy process (F-AHP) and fuzzy additive ratio assessment (F-ARAS) to fulfill the research objectives. Fuzzy Delphi is used to finalize the CSFs of outsourcing and F-AHP provides the relative weights to it. F-ARAS is used to prioritize the outsourcing performance indicators with respect to CSFs. The empirical case investigation of three Indian large-scale public sector process industries is conducted to demonstrate the applicability of the proposed framework. Findings The result shows that increased dominance in core activity, ability to increase or decrease capacity, improved financial performance, optimized resource utilization and increased market share are the top five performance outcomes because of the adoption of outsourcing CSFs. Research limitations/implications Factors such as cultural, political, environmental and size of the organization may have a significant implication on the research results. Originality/value This is a novel approach towards the prioritization of performance outcomes of outsourcing. Moreover, the present research is a helpful tool to manage outsourcing and choosing which performance outcome of outsourcing ought to be used to measure implementation. This will help to recognize potential opportunities and preparing strategic planning for both short-term and long-term goals.
