PurposeTo investigate the application of multi‐attribute utility theory (MAUT) to aid in the decision‐making process when performing benchmarking gap analysis.Design/methodology/approachMAUT is selected to identify the overall best‐in‐class (BIC) performer for performance metrics involving inventory record accuracy within a public sector warehouse. A traditional benchmarking analysis is conducted on 14 industry warehouse participants to determine industry best practices for the four critical warehouse metrics of picking and inventory accuracy, storage speed, and order cycle time. Inventory and picking tolerances are also investigated in the study. A gap analysis is performed on the critical metrics and the absolute BIC is used to measure performance gaps for each metric. The gap analysis results are then compared to the MAUT utility values, and a sensitivity analysis is performed to compare the two methods.FindingsThe results indicate that an approach based on MAUT is advantageous in its ability to consider all critical metrics in a benchmarking study. The MAUT approach allows the assignment of priorities and analyzes the subjectivity for these decisions, and provides a framework to identify one performer as best across all critical metrics.Research limitations/implicationsThis research study uses the additive utility theory (AUT) which is only one of multiple decision theory techniques.Practical implicationsA new approach to determine the best performer in a benchmarking study.Originality/valueTraditional benchmarking studies use gap analysis to identify a BIC performer over a single critical metric. This research integrates a mathematically driven decision analysis technique to determine the overall best performer over multiple critical metrics.

Purpose The paper focused onto the development of microcapsules by using two essential oils. It proposes the uses of eucalyptus oil and cedarwood oil as a natural insecticide. The purpose of this paper is to demonstrate the application of developed microcapsules to impart insect repellency on textile substrate. Design/methodology/approach The paper opted for an experimental study using two essential oils and gum in formations of microcapsules through a simple coaseravtion encapsulation technique. The developed solution was analyzed, including confirmation of size and structure through. Application of developed finish on substrate was also undertaken to prove better ability as repellent fabric. Findings The paper highlights useful invention of microencapsulated fabric developed with the combination of gum acacia and eucalyptus oil as core and shell material. The developed fabric has better ability to repel silverfish as compared to microencapsulated fabric developed with gum acacia (shell) and cedarwood oil (core). Research limitations/implications Due to the lack of time and less availability of essential oils, only two oils were used to test the insect repellent behavior. Practical implications This paper fulfills an identified need, it includes implications for the development of a very useful natural insecticide to repel silverfish (Lepisma saccharina) insect. This insect is a very common problem found in cloth wardrobes and bookshelves; it mainly attacks the fabric with cellulosic content and starch. Social implications Society will get major benefit of using these microencapsulated finished fabrics, which repel silverfish from their home and keep their clothing and books safe for longer period. The natural fragrance and medicinal benefits of these essential oils can never be ignored. Originality/value This study sets a new approach to repel insects like silverfish from the bookshelves and clothing wardrobes. A layer of insect repellent microencapsulated finished fabric can be added in these shelves and wardrobes. It is an eco-friendly approach of using natural essential oils instead of chemical insecticides.

Purpose Literature on eco-innovation brings insights that help to understand which factors trigger innovation focused on sustainability in companies. However, when analyzing the studies that comprise such drivers, it appears that most of them were focused only on describing them in isolation. Therefore, this study aims to understand which are the combinations of drivers that favor the adoption of eco-innovation in slaughterhouses located in the Brazilian state of Rio Grande do Sul. Design/methodology/approach This study has used the crisp-set qualitative comparative analysis (csQCA) as the data analysis technique, in addition to the previous application of Most Similar Different Outcome/Most Different Same Outcome (MSDO/MDSO). Findings This study identified eight internal and external drivers that explain the differences in performance of eco-innovative and non-innovative slaughterhouses. These drivers generate 13 combinations of factors capable of favoring the adoption of five types of eco-innovation. Research limitations/implications A limitation identified was the difficulty to obtain information held by companies on environmental issues. In addition, in each company the authors only approached one respondent. Practical implications The use of combinations is identified by companies and governmental and non-governmental organizations to promote eco-innovation in slaughterhouses. Originality/value This study may be considered original for its contribution to the improvement of eco-innovation literature by describing how the drivers identified combine to favor the adoption of certain types of eco-innovation. In addition, the authors also made an original use of csQCA, linked with MSDO/MDSO, in the field of eco-innovation.

Purpose The purpose of this paper is to report the results of testing a new approach to strategic sustainability and resilience – Sustainable Resilient Strategic Decision-Support (SuReSDS™). Design/methodology/approach The approach was developed and tested using action-research case studies at industrial companies. It successfully allowed the participants to capture different types of value affected by their choices, optimise each strategy’s resilience against different future scenarios and compare the results to find a “best” option. Findings SuReSDS™ enabled a novel integration of environmental and social sustainability into strategy by considering significant risks or opportunities for an enhanced group of stakeholders. It assisted users to identify and manage risks from different kinds of sustainability-related uncertainty by applying resilience techniques. Users incorporated insights into real-world strategies. Research limitations/implications Since the case studies and test organisations are limited in number, generalisation from the results is difficult and requires further research. Practical implications The approach enables companies to utilise in-house and external experts more effectively to develop sustainable and resilient strategies. Originality/value The research described develops theories linking sustainability and resilience for organisations, particularly for strategy, to provide a new consistent, rigorous and flexible approach for applying these theories. The approach has been tested successfully and benefited real-world strategy decisions.

Purpose This paper aims to analyze the contribution of the diffusion of innovation framework to eco-sustainability. It examines the interplay of organizational environment, innovation and innovation adopters’ characteristics on the diffusion of environmental sustainability. Design/methodology/approach The data for empirical validation were obtained through an offline survey from the hospitals. The proposed conceptual framework was tested using the hierarchical regression analysis technique. Findings The results show that diffusion of innovation characteristics and organizational environment significantly influence the environmental sustainability index. The adopters’ characteristics do not have any direct effect on the environmental sustainability but this effect becomes significant in the presence of a favorable organizational environment. Practical implications Focusing on innovations that offer an advantage over the existing processes, are compatible with the existing system, are uncomplicated and simple to implement and can be experimented before full implementation may greatly accelerate the adoption of eco-innovations in hospitals. Fostering an organizational environment where employees are encouraged and rewarded for contributing to sustainable innovations can play a substantial role in the implementation of environmental sustainability innovations. Originality/value This study is an original contribution as it advances the limited understanding of the predictors and moderators of environmental sustainability in hospitals.

Purpose – Result-based management (RBM) is common approach used in the development sector to initiate, plan and implement projects. However, to the knowledge of the authors the approach has hardly been used in delivering projects in other sectors, for example, information technology, infrastructure or business. The purpose of this paper is to document a case study in which the RBM approach was used to guide the delivery of a business project in Botswana. Design/methodology/approach – A case study strategy was used to document the delivery process of the project. Data were collected from a variety of sources that included review of documents, interviews, focus discussions and a site visit. The content analysis technique was used to analyse the collected data. Findings – The case illustrates the possibility of using the RBM approach to initiate, plan and implement a project in the business sector. Research limitations/implications – Being a case study, the approach needs to be tested with more case studies. Practical implications – Apart from illustrating the possible use of RBM approach, the paper illustrates systematic processes used in the case study for project delivery. It also outlines some of the resultant challenges which may be appreciated by practitioners, academics and trainees. Originality/value – The use of RBM approach in guiding the delivery of a business project.

Purpose The purpose of this paper is to describe the authors’ experience operationalizing the care delivery value chain (CDVC) as a management and continuous quality improvement (QI) approach to strengthen HIV/AIDS services provided in Northern Togo through addressing gaps across a care continuum. Design/methodology/approach The authors led a series of discussions to develop a CDVC specific to existing HIV/AIDS services in Northern Togo. Using the CDVC framework, 28 specific gaps in service delivery were identified and integrated into a strategic QI plan. Findings At 12 months, 92 percent of delivery gaps had demonstrated improvement. The CDVC framework proved to be valuable in the following ways. First, it facilitated the first comprehensive mapping of HIV/AIDS services in the Kara region of Togo. Second, it enabled the identification of gaps or insufficiencies in the currently available services across the full continuum of care. Third, it catalyzed the creation of a strategic QI plan based on identified gaps. Research limitations/implications This case description is the authors’ experience in one setting and should not be considered comparative in nature. Furthermore, the approach described may not be applicable to all initiatives and/or organizations. As described, the lack of sophisticated and comprehensive data collection systems limited the authors’ ability to collect reliable data on some of the QI initiatives planned. Practical implications The operationalization of the CDVC framework is an effective approach to drive continuous QI. Originality/value Through the operationalization of the CDVC, the authors developed a new approach for assessing existing services, identifying gaps in service delivery and directing continuous QI initiatives in a strategic manner.

PurposeThis paper develops a generalizable, machine-learning-based method for measuring established marketing constructs using passive analysis of consumer-generated textual data from service reviews. The method is demonstrated using topic and sentiment analysis along dimensions of an existing scale: lodging quality index (LQI).Design/methodology/approachThe method induces numerical scale ratings from text-based data such as consumer reviews. This is accomplished by automatically developing a dictionary from words within a set of existing scale items, rather a more manual process. This dictionary is used to analyze textual consumer review data, inducing topic and sentiment along various dimensions. Data produced is equivalent with Likert scores.FindingsPaired t-tests reveal that the text analysis technique the authors develop produces data that is equivalent to Likert data from the same individual. Results from the authors’ second study apply the method to real-world consumer hotel reviews.Practical implicationsResults demonstrate a novel means of using natural language processing in a way to complement or replace traditional survey methods. The approach the authors outline unlocks the ability to rapidly and efficiently analyze text in terms of any existing scale without the need to first manually develop a dictionary.Originality/valueThe technique makes a methodological contribution by outlining a new means of generating scale-equivalent data from text alone. The method has the potential to both unlock entirely new sources of data and potentially change how service satisfaction is assessed and opens the door for analysis of text in terms of a wider range of constructs.
