Abstract
Purpose
The purpose of this paper is to propose that the effectiveness of organizational design-manufacturing integration (ODMI) practices is contingent upon the degree of complexity of the manufacturing environment. The paper submits that the level of use of ODMI ought to match the level of complexity of the manufacturing environment. The paper puts forward the hypothesis that when a misfit occurs between ODMI and complexity (high use of ODMI practices in low complexity environments or low use of ODMI practices in high complexity environments) manufacturing operational performance declines.
Design/methodology/approach
The paper tests the hypothesis based on a survey database of 725 manufacturers from 21 countries. The measurement model was assessed with confirmatory factor analysis and the hypothesis was tested with linear regression.
Findings
A misfit between the level of ODMI use (job rotation and co-location) and manufacturing complexity (product and process complexity) has a negative effect on manufacturing operational performance dimensions of quality, delivery and flexibility. Post hoc analyses also suggest that firms that operate in different environments in what concerns the rate of change in process technologies suffer differentiated negative impacts of ODMI-complexity misfit.
Research limitations/implications
Future studies could extend this research to other dimensions of design-manufacturing integration, such as technological practices.
Practical implications
Manufacturers with high levels of complexity should invest strongly in ODMI practices. However, manufacturers with low levels of complexity should invest in these practices with caution since the expected payoffs may not outweigh the effort.
Originality/value
The study assesses fit as a simultaneous set of contingency factors, applying profile-deviation analysis to ODMI and operational performance relationships. By focusing on plant-level manufacturing complexity, this study complements existing studies of product development complexity which tend to focus on project-level complexity.

Abstract
Purpose
The purpose of this paper is to identify similarities and differences between qualitative-based and quantitative-based research, and to present recommendations for designing and conducting the research so that the possibilities of publishing it in leading Operations Management (OM) journals are improved.
Design/methodology/approach
The paper takes its outset in contributions made at the 2016 European Operations Management Association Young Scholars Workshop. The theme of the workshop was “Designing and developing research projects in Operations Management – from concept to publication.” Taking the perspectives of the case researcher, the survey researcher and the editor/reviewer, the authors present and discuss the views on and experiences with designing research for publication.
Findings
The authors identify a number of recommendations that researchers should use when designing, conducting, and presenting their research for publication. The recommendations include the need to clearly and concisely establish relevance, account for choice of methodology as well as the operationalization, sampling, analytical, and validation methods used, and demonstrate the contribution of the paper in the discussion section. Furthermore, the authors draw attention to the importance of developing a publication strategy as early as possible. Other important aspects include the title of the paper, keywords selection, and rejection criteria. Finally, the authors stress the importance of “total quality management” in designing and executing OM research.
Originality/value
Going beyond the standard author guidelines found at journal web sites, the authors present a collection of viewpoints, which are based on the authors’ experiences as reviewers, editors, and evaluators of OM research projects and their designs.

Abstract
Purpose
Multichannel (MC) service providers have been adopting a wide diversity of front-office service delivery models, i.e. different ways of employing channels to support the delivery of the service activities that involve customer interaction. Despite this, we are still faced with a paucity of concepts to understand the myriad of possible choices. The purpose of this paper is to develop a theoretical framework and basic design architectures to provide a structured understanding of the diversity of operational design choices for MC front-office service delivery models, their efficacy implications, and how they fit with the provider’s service strategy.
Design/methodology/approach
The study employs the analytical conceptual approach. The authors logically develop the architectures based on the operations management theory and provide corresponding empirical illustrations based on secondary sources, direct observation, and case studies.
Findings
The authors propose two theoretically meaningful dimensions to characterize and distinguish between delivery models (channel redundancy and channel span) and put forward four anchor architectures for such models: generalist, parallel, constricted, and centralized. The authors identify the operational efficacy implications (effectiveness and efficiency) of the different architectures, and develop a set of propositions and design principles for selecting appropriate architectures.
Research limitations/implications
Future research should develop empirical measures for the dimensions underlying the architectures.
Originality/value
The study extends existing service process classifications by capturing the MC traits of front-office processes. The authors offer design principles to assist firms in selecting architectures that are aligned with their service strategy. The framework and architectures provide seminal concepts to support a wealth of future empirical studies.

Abstract
Purpose
This study theoretically articulates and empirically validates a model of relationships between market complexity (competition intensity, heterogeneity and technological change), strategic focus on product and service differentiation, ADS offerings and differentiation advantage.
Design/methodology/approach
The authors develop and test hypotheses through structural equation modeling based on data from the Sixth International Manufacturing Strategy Survey (IMSS-VI), involving 931 manufacturers from 22 countries.
Findings
The results indicate that (1) market complexity has a positive impact on strategic focus on product and service differentiation; (2) focus on product and service differentiation, but not market complexity, has a positive impact on the extent to which business units offer ADS to their customers; (3) ADS have a positive impact on service differentiation advantage, but no influence on product differentiation advantage.
Practical implications
Managers should incorporate decisions related to ADS provision as part of their manufacturing strategy formulation processes to align markets, strategic focus on product and service differentiation, and ADS provision. ADS seem an appropriate lever for market differentiation, because they appear not only to support service differentiation advantage, but also to be consistent with strategic focus on product differentiation.
Originality/value
The study provides novel insights and large-scale empirical evidence on the influence of the market environment on the offering of ADS, as well as on how relationships between the product and service activity in the manufacturing organization may affect differentiation advantage.

Abstract
Purpose
This study aims to identify the perception of people in a Portuguese company regarding the main barriers to the effectiveness of the existing performance measurement system (PMS) and whether those perceptions are dependent of people’s hierarchical levels, education levels, work shifts, gender and department.
Design/methodology/approach
Primary data was collected through structured interviews (adapted to three levels of interviewees in the company hierarchy) and Likert scale questionnaires. Descriptive statistical analysis of the collected data was performed as well as a chi-square test.
Findings
The results provide an insight on the perception of barriers to the PMS effectiveness in the company. After performing interviews and questionnaires it was possible to identify that the main perceived barriers were: poor communication system and issues on target definition, lack of trained resources, employee involvement, indicators understanding and use for improvement.
Practical implications
This study is the starting point to develop actions aiming to eliminate, or at least mitigate, the impact of the barriers on the PMS effectiveness.
Originality/value
PMSs play an essential role in an organization, so it is essential to identify what hinders its effectiveness. This study opens the discussion by diagnosing the company’s perception of the barriers to PMS effectiveness.

Abstract
Purpose
The purpose of this paper is to examine the relationship between product customization and servitization strategies, specifically the relationship between product customization strategy intensity and degree of servitization (offering of basic and/or advanced services) and the moderating role of product customization strategy alignment on that relationship.
Design/methodology/approach
The authors develop and test hypotheses through partial least squares path modeling to analyze data from the Sixth International Manufacturing Strategy Survey, involving 931 manufacturers in 22 countries.
Findings
The results indicate that customization strategy intensity is positively associated with the offering of basic and advanced services; these relationships are not moderated by customization strategy alignment.
Practical implications
Manufacturers pursuing product customization strategies may be especially well positioned to servitize, even those with misalignment in strategic choices. Paradoxically, while manufacturers of standard products might look at servitization as an attractive strategy to differentiate their value proposition, they appear to be less servitized than manufacturers pursuing product customization.
Originality/value
This is one of the first studies to examine how manufacturing strategy choices (intensity and alignment) influence the adoption of servitization strategies. The study introduces manufacturing strategy as a contingency factor that influences the adoption of servitization, answering calls for the study of servitization contingencies.

Abstract
Purpose
The purpose of this paper is to compare the well-known value stream mapping (VSM) with a recent tool named waste identification diagram (WID), regarding the capacity of information representation and easiness of interpretation.
Design/methodology/approach
The work begins with a brief literature review comparing the main tools for representation of production units, with special emphasis on VSM and WID, in terms of ability to identify several types of waste. Then, the authors developed the VSM and the WID of a specific production unit and after that several groups composed by students of Industrial Engineering (IE) and/or professionals from industry were asked to analyse/interpret only one of these diagrams. Finally, a questionnaire with closed and open questions was applied to the groups to evaluate the analysed tool.
Findings
In general, the results revealed that WID is more effective than VSM and participants recognized that most of the WID elements are relevant. Specifically, a measure coined overall effectiveness was applied (based on the response time and percentage of correct interpretations), indicating a clear advantage of WID (22 per cent of correct interpretations per minute) compared to VSM (9 per cent of correct interpretations per minute). The main drawback pointed to the WID is the lack of representation of the information flow.
Originality/value
This work contributes to the IE field by revealing WID as a new promising graphical tool for representation of production units, especially in terms of identification/quantification of wastes. The tool was quantitative and qualitatively evaluated by persons both from academia and industry.

Abstract
Purpose
The purpose of this paper is to theoretically articulate and empirically test an integrated model of capability antecedents and performance outcomes of servitization strategies. The authors characterize servitization strategies based on the offering of two types of services: basic services (BAS) and advanced services (ADS).
Design/methodology/approach
Hypotheses are tested based on statistical analyses of a large survey of manufacturers from different countries and sectors.
Findings
The authors find that manufacturing capabilities associate with the provision of BAS, while service capabilities associate with both BAS and ADS; BAS do not impact financial performance, but support the offering of ADS; there seem to be naturally occurring servitization trajectories involving the gradual development of balanced levels of BAS and ADS and adequate levels of manufacturing and service capabilities.
Research limitations/implications
The findings on servitization trajectories are based on the observation of manufacturing business units at different stages of servitization (cross-sectional data).
Practical implications
Manufacturers wishing to servitize should distinguish between BAS and ADS and deploy a balanced adoption of BAS and ADS, using BAS as a platform. This should be accompanied with the building of appropriate capabilities.
Originality/value
This is one of the first studies to show an explicit link between different servitization strategies, capabilities, and servitization maturity. It provides new insights into the servitization paradox and servitization trajectories.

Abstract
Purpose
This paper aims to assess the economic effects of climate change on the Mediterranean’s irrigated agriculture and how the adoption of alternative crop varieties adapted to the expected length of the growing season can be an effective adaptation measure.
Design/methodology/approach
A case study of two irrigation areas in Southern Portugal is used to assess the response to climate change impacts on crop yields and irrigation requirements, and an agricultural supply model is calibrated using a positive mathematical programming (PMP) approach was developed.
Findings
Climate change reduces crop yields and causes a slight decrease in irrigation requirements, which could allow an increase in the irrigated area. However, positive impacts on rural areas regarding employment and investment are not expected. The adoption of adaptation measures based on alternative crop varieties, which could maintain crop yields at current levels, increases dramatically the economic value of water and mitigates losses in farm income.
Research limitations/implications
The impacts on output and input market prices, as well as other biophysical impacts (for instance, CO2 and water availability), are important in understanding the effects of climate change on irrigated agriculture, but they were not considered in this study. While this may be a limitation, it can also be a stimulus for further research.
Practical implications
This is an empirical paper, whose results contribute to improving knowledge about the effects of climate change on irrigated agriculture in Mediterranean areas, namely, its economic impacts on returns and the use of agricultural resources (land, water, labour and capital). Other practical implications of the paper are associated with the methodological approach, which provides a framework able to deal with the complexity and multidimensional effects of climate change.
Social implications
The results of the paper provide important information for scientists, politicians and other stakeholders about the design of more effective adaptation measures able to mitigate the effects of climate change.
Originality/value
Crop yields and irrigation requirements were previously calculated based on data generated by the regional climate models. This is the first time that an application is developed for Portugal. Two distinct profiles of irrigation areas were studied and a large set of crops was considered, which is not common in the existing studies. To specify the PMP approach used to calibrate the agricultural supply model, exogenous crop-specific supply elasticities were estimated through a least square model, which is not common in previous studies.
