Purpose The purpose of this paper is to first present potential areas of research for measuring sustainability performance that emerged in a joint researcher–practitioner workshop at the 19th Environmental and Sustainability Management Accounting Network Europe Conference, organized in cooperation with the World Business Council for Sustainable Development. Second, the methodology applied to gain these insights, the world café approach, is critically reviewed. Design/methodology/approach The applied method, a world café approach, facilitates collaborative dialogue and was used in the workshop to uncover underlying research themes. A generalized process flow diagram for a world café is presented, highlighting critical aspects that can guide researchers considering the use of the world café method. The results are structured by means of the 5 W (who, what, where, when, why) and 2 H (how) questions, also known as the elements of circumstance. Findings Key topics discussed by conference attendees are identified and an overview of potential areas of research are established concerning “measuring sustainability performance”, with a topical focus on impact measurement and value of sustainability. Furthermore, based on the topics identified by practitioners and researchers, this paper develops a list of questions that can guide future research. Finally, the world café method as a means of generating insights into complex topics such as sustainability performance is evaluated. Practical implications The list of research questions identified in this paper can serve as guidance for researchers for selecting relevant, practice-oriented research topics. The value of the world café method as an approach to facilitating the generation of participatory and collaborative insights was confirmed for sustainability management. The generalized process flow diagram can act as a starting point when considering the world café method for facilitating large transdisciplinary groups. Social implications The world café is a method for facilitating practitioners and researchers exchange, and thereby presents an opportunity for spanning the research–practice gap. By bringing practitioners and researchers together to identify research areas, future research is more likely to have positive social implications. Originality/value The paper presents a recent interpretation of future research gained from a large number of sustainability professionals, including practitioners and researchers, by bringing them together using a world café. The world café is a valuable method for a collaborative set-up with immediate feedback loops, which encourages dialogue, in contrast to surveys or individual interviews, on future developments in the field.

<p>Manajemen mutu merupakan salah satu kunci sukses perusahaan untuk memenangkan pasar dan mencapai tujuaannya. Begitu juga yang harus dilakukan oleh <em>Agribussiness Development Center</em><em> </em>(ADC)<em> </em>Institut Pertanian Bogor (IPB)<em>-Taiwan International Cooperative Development Fund</em> (ADC IPB-ICDF Taiwan). Produk unggulan dari perusahaan adalah jambu Kristal yaitu buah dengan biji yang sedikit, rasa manis dan renyah. Tahun 2012, perusahaan hanya mampu memenuhi sebesar 31% permintaan pasar atas jambu Kristal <em>grade</em> A, serta <em>grade</em> B+, B dan C mencapai 69%. Metode analisis yang digunakan adalah Analisis <em>Defect per Opportunity</em> (DPO), Analisis <em>Defect per million Opportunity</em> (DPMO), Diagram alir proses (<em>Process Flow Diagram)</em><em>, </em>Diagram pareto (<em>Pareto Chart</em>), Peta kendali, Diagram Sebab Akibat<em> (Fishbone</em> <em>Diag</em><em>ram</em>), <em>Failure Mode and Effect Analysis</em> (FMEA) dan Metode Six Sigma. Berdasarkan hasil analisis, terdapat enam <em>Critical </em><em>T</em><em>o Quality</em> (CTQ) antara lain pembibitan, kondisi lingkungan, pemupukan, perawatan, panen dan pasca panen. Hasil perhitungan kapabilitas sigma selama tahun 2012 masih berada kisaran 2-sigma. Hal ini menunjukkan masih banyak <em>defect</em> dan kapabilitas sigma berada di bawah target (3,4 DPMO). Dengan demikian, untuk saat ini ADC IPB-ICDF Taiwan, Bogor masih belum realistis untuk mengaplikasikan <em>six sigma</em> dikarenakan produk agribisnis yang rentan dan dipengaruhi oleh berbagai faktor alam yang sulit untuk dikendalikan.</p>Kata kunci : jambu Kristal, pengendalian mutu, <em>six sigma </em>

Abstract Comparison of various methods for analyzing characteristic features of a total system is demonstrated. Process flow diagram (PFD) shows streams and main apparatuses schematically. Hence we can imagine system configuration. However, it gives no quantitative information. Energy flow and exergy flow diagrams, respectively, show information about the first law and the second law of thermodynamics. The advantages of these diagrams disappear for a large and complex system. Then we propose a new diagram, a process flow diagram with process vectors. Base frame of this diagram is the same of the PFD, but information about H and ε of important streams and ΔH and Δε for each change of substances is represented by drawing process vectors. And features of exergy loss are clearly depicted by their combination.
