International Journal of Agile Systems and Management (12 papers in press)
Abstract: Some decades ago, the concept of "ambidexterity" was introduced in the theory and practice of organization management, but only recently applied to the management of the entire supply chain. Our goals in this article are to propose a definition for Ambidextrous supply chains in the field of apparel and to study the three leaders of the industry and identify if they balance their supply chain archetypes in their way to Ambidexterity. The apparel industry is one of the most global and fluctuating industries in the world, and apparel supply chains play a strategic role in the growth of the industry and permanency of the brands through end-consumer responsiveness. An ambidextrous supply chain refers to the ability to maintain daily operations excellence while looking for constant innovation and the ability to keep balance. This balance might be achieved through an ambidextrous supply chain. The three studied cases show how organizations can achieve ambidexterity by managing trade-offs latent in this industry.
Keywords: ambidexterity; supply chain archetypes; apparel industry; innovation process; strategic management; case study.
Analysis of agile supply chain enablers for an Indian manufacturing organisation
by Bharat Singh Patel, Atul Kumar Tiwari, Manish Kumar, Cherian Samuel, Goutam Sutar
Abstract: The contemporary manufacturing companies are making endeavours to implement agility in their supply chain to become competitors in highly uncertain and fast changing business environment. To be truly agile, a supply chain must possess a number of distinguishing characteristics which can be called as Agile Supply Chain (ASC) enablers. Again, to focus and attentive to all agility enablers effectively is not economical. Thus, to overcome this problem an AHP based framework is proposed in this study that would help the supply chain managers to assign relative importance to various agility enablers. The objective of present work is to categorise ASC enablers and examine its relative importance for better implementation of agility in perspective of an Indian manufacturing industry. This study deploys, Analytic Hierarchy Process (AHP), a popular Multi-Criteria Decision Making (MCDM) tool as a solution methodology, such that the decision problem breaks into hierarchy of different levels constituting goal, criteria and alternatives. A case study of a North India based manufacturing organisation is presented, in which four experts from the case-organisation and two experts from academia are contemplating to reach consensus for the pair-wise comparison of criteria and alternatives. The results show that there are three enablers namely virtual enterprises, customer satisfaction and adaptability are among the top priority enablers; enabler collaborative relationship is the moderate priority enabler and remaining three enablers i.e. use of information technology, market sensitivity and flexibility are the lowest priority enablers. To effectively implement agility in the supply chain, this study proposes that the manufacturing industries need to focus on the most important ASC enablers and also address the enablers with the least important at a later stage.

Multidisciplinary Design Automation A Conceptual Framework for Working with Product Model Extensions
by Tim Heikkinen
Abstract: Design automation can be used to support efficient information handling and knowledge processing in computer-based product modelling, as well as make possible new design exploration and optimisation capabilities. To be able to utilise and manage design automation systems over time, it is important to understand how the disciplinary methods and models are dependent on each other through the product model constituents and then how these relations should be built to support maintenance, leveraging and future reuse. Awareness of the concrete representation of relations could support the systems traceability and transparency, and depending on the chosen technique, comprehension and extendability can be affected. This paper presents a conceptual framework for how a set of product model constituents are, can and to some extent, should be extended to define relations in multidisciplinary design automation systems.
Keywords: Multidisciplinary design automation; system relations; extended product model.

Towards the democratisation of design: A generalised capability model for FDM
by Mark Goudswaard, Ben Hicks, Aydin Nassehi
Abstract: The manufacture of functional parts via Fused Deposition Modelling (FDM) is inhibited by a lack of understanding of the manufacturing process itself. This results in parts having unpredictable and unreliable mechanical properties. Correspondingly, this paper considers the incorporation of Capability Profiles (CPs) in the design process for FDM as a solution. The evolved requirements of CPs for FDM when compared to traditional subtractive processes are considered and the necessary process information that would be incorporated within them is presented. A review of existing literature of the effect of process parameters on mechanical properties of FDM parts identifies process variability and the effects of shape and scale as areas currently insufficiently studied. To address this, a programme of tensile tests are conducted revealing i) significant variation (26%) in identical test specimens ultimate tensile strength ; ii) that properties do not scale linearly with specimen size; and iii) that cross-sectional shape directly impacts mechanical performance. The results of these tests are pooled with those from existing literature to define the parameters that need to be included within a capability profile for FDM. The functionality of such a capability profile is shown by demonstrating how these parameters would be used to determine the mechanical properties of an artefact.
Keywords: Democratisation of Design; Filament Deposition Modelling; Mechanical Testing; Material Testing; Capability Profiles.
Learning organization as technology for the socio-economic paradigm implementation
by Nataša Rup?i?
Abstract: The paper discusses prospects of the paradigm shift and proposes the learning organization concept as the technology for the implementation of the learning socio-economic paradigm. The learning socio-economic concept can be described as an overarching business model or a paradigm, providing governing principles regarding interests of major stakeholders. The proposed learning organization structure-behaviour platform can be analysed from the organizational and individual perspective. The proposed concept based on the learning organization premises can contribute to the development of the social democratic process and welfare so the main social challenge within the learning framework becomes stimulating positive manifestations of cooperation and complexity as well as increasing behavioural variety as a means of fighting entropy. The paper therefore represents an attempt to provide a descriptive and normative guidance for developing a model for modern business making in terms of personal growth, business excellence and social inclusiveness and sustainability.
Keywords: paradigm; socio-economic paradigm; learning socio-economic paradigm; learning organization.
A Fuzzified Story Point Approach For Agile Projects
by Anupama Kaushik, Devendra Kr. Tayal, Kalpana Yadav
Abstract: Effort estimation is very important for any software development organization. A lot of work is present for effort estimation in traditional software development but, effort estimation in agile software development (ASD) poses a great research challenge as not much of work is done in this regard. This work proposes a fuzzy approach to effort estimation in agile software development environment by identifying first the cost drivers affecting the effort of agile projects and then calculating the effort using fuzzified story point approach. These cost drivers are collected by taking a web survey from the companies in Delhi-NCR which practise ASD. Statistical tests are also performed in order to show the dependency of effort on these cost drivers. Here, fuzzy interval type-2 is used which is compared with fuzzy type-1. It is found that, the effort calculated using fuzzy interval type-2 is better than fuzzy type-1.

Critical Factors in Information Technology Capability for Enhancing Firms Environmental Performance: Case of Indonesian ICT Sector
by Ferry Jie, Darius Antoni, Ahmad Abareshi
Abstract: Information technology (IT) capability can be adopted by organisations to improve their environmental performance in order to meet environmental regulations, improve their profitability and enhance their competitive position in the marketplace. The main purpose of this paper is to develop a research framework which can serve as a basis to understand how IT capability leads to improvement of environmental performance and what critical IT capabilities would improve environmental performance in an organisation. The hypothesised framework is developed based on a review of the literature on RBV theory and green IT. The data is collected using a questionnaire method. Then the questionnaire is structured and presented on a seven-point Likert scale to facilitate examination of the relationship between the role of IT capability and organisational environmental performance. A seven-point Likert scale is used to measure the perceptions of participants in using IT capability for improving environmental performance in each organisation, which later determined the critical factors of IT capability for improving environmental performance. The sampling unit of this study is from managerial levels in selected 1265 Indonesian ICT organisations based on the list provided by the Ministry of Trade, Republic of Indonesia. The findings show that environmental performance is influenced by IT infrastructure quality, IT human resources competence, and environmental IT competence.
Keywords: IT capability; environmental performance; IT infrastructure; IT human Resources; green IT.
Sample Median Approximation on Stochastic Data Envelopment Analysis
by Anton Abdulbasah Kamil, Marah Doli Nasution, Herman Mawengkang
Abstract: This paper study a new approximation model to solving Stochastic Data Envelopment Analysis (SDEA) Problem. The proposed approach is based on problems that might occur in everyday life. This paper discusses the approach in determining the efficiency and super efficiency ratings of a Decision Making Unit (DMU) in the DEA model with stochastic data. In determining efficiency, SDEA is first transformed into an equivalent deterministic DEA by changing its chance constraints in such a way that the SDEA problem can be solved easily. The author proposes an approach technique called a Sample Median Approximation (SMA) to change the chance constraints so that it will be easy to get the optimal solution in determining the efficiency of DMUs. In the process, the data to be processed first is determined by the median average which will later be considered to represent the actual sample average. As a numerical example, the author resolves the vendor selection problem as presented by Wu and Olson (2006) in their paper. By taking the same parameter value (alpha = 0.2 and beta = 0.9), the efficiency score and super efficiency of the problem are obtained.
Keywords: Stochastic Data Envelopment Analysis; Sample Median Approximation; super efficiency.

by Alessandra Papetti, Monica Pandolfi, Margherita Peruzzini, Michele Germani
Abstract: Industrial process digitalization is pervading numerous areas of production system, including sustainability. The study presents a method to affirm how the social sustainability of a company also passes through the protection of the welfare of the worker and describes a case study focused on SMEs. The method considers different aspects including the characteristics of the worker/s, the working context, and the content of the work activity. From this point of view, objectives of social sustainability in the factory environment have been defined, which are made up of multifactorial variables that are often present in the same context. The support of the technology accompanying the method is the IoT system, in particular the integration of the wearable technological devices. Following the proposed method, the results of the case study offer many in-depth insights, from the objective analysis of personal characteristics to the organization of work, from the use of technological tools to the concomitant administration of questionnaires, from the application of international standards to the association of methodologies more or less recognized, but able to systematize generally dated evaluation processes. In any case, pursuing the same objective of ensuring social sustainability.

BUSINESS PROCESS MANAGEMENT SYSTEMS IN PORT PROCESSES: A SYSTEMATIC LITERATURE REVIEW
by Alicia Martín-Navarro, María Paula Lechuga Sancho, José Aurelio Medina-Garrido
Abstract: BPMs or Business Process Management Systems represent a technology that automates business processes, connecting users to their tasks. There are many business processes within the port activity that can be improved through the use of more efficient technologies and BPM in particular, which can help to coordinate and automate critical processes such as cargo manifests, customs declaration the management of scales, or dangerous goods, traditionally supported by EDI technologies. These technologies could be integrated with BPM, modernizing port logistics management. The aim of this work is to demonstrate, through a systematic analysis of the literature, the state of the art in BPM research. For this, a systematic review of the literature of the last ten years was carried out. The works generated by the search were subsequently analysed and filtered. After the investigation, it is discovered that the relationship between BPM and the port sector is practically non-existent which represents an important gap to be covered and a future line of research.
