Cost-risk contingency framework for managing cost overrun in metropolitan projects: using fuzzy-AHP and simulation

PurposeRisk analysis plays a vital role in controlling and managing cost overruns in complex construction projects, particularly where uncertainty is high. This study attempts to address an important issue of cost overrun that encountered by metropolitan rapid transit projects in relation to the significance of risk involved under high uncertainty.Design/methodology/approachIn order to solve cost overrun problems in metropolitan transit projects and facilitate the decision-makers for effective future budgeting, a cost-risk contingency framework has been designed using fuzzy logic, analytical hierarchy process and Monte Carlo simulation.FindingsInitially, a hierarchical breakdown structure of important complexity-driven risk factors has been conceptualized herein using relative importance index. Later, a proposed cost-risk contingency framework has investigated the expected total construction cost in order to consider the additional budgeted cost required to mitigate the risk consequences for particular project activity. The results of cost-risk analysis imply that poor design issues, an increase in material prices and delays in relocating facilities show higher dependency and increase the risk of cost overrun in metropolitan transit projects.Practical implicationsThe findings and implication for project managers could possibly be achieved by assuming the proposed cost-risk contingency framework under high uncertainty of cost found in this research. Furthermore, this procedure may be used by experts from other engineering domains by replacing and considering the complex relationship between complexity-risk factors.Originality/valueThis study contributes to the body of knowledge by providing a practical contingency model to identify and evaluate the additional risk cost required to compute total construction cost for getting stability in future budgeting.

Contingency framework for understanding quality in public and private hospitals of India

Purpose Health-care delivery organizations (hospitals) constitute a complex adaptive system; hence, a contingency perspective is imperative to guide the design of customized approaches to quality management in different health-care settings. Accordingly, this paper aims to propose a contingency framework to advance the understanding of the relationship between situational factors and effectiveness of quality approaches in health-care organizations (HCOs), such as hospitals in India. Design/methodology/approach Related literature was reviewed to identify existing research and theories related to quality and quality approaches, situational factors of the HCOs (hospitals) and some existing logical evidence on public and private hospitals in India. Then a contingencies framework for quality and quality approaches was conceptualized. Findings This paper proposes contingent determinants arise out of conceptualization of the HCOs (hospitals) from different system perspective such as rational system, natural system, open system and integrative system; uncertainty because of physicians’ behaviour, nurses’ approach and a dual line of authority; and the task environment such as patients, competition and economic pressure. These determinants represent situational constructs to the quality enhancement of any attempt at quality approaches. While these determinants have an influence on the quality and quality approaches of the HCOs (hospital), it is imperative to build any quality improvement strategy to work effectively, i.e., quality approach is dependent on determinants of the contingencies of the hospital’s environment, be it external or internal. Propositions for future research are also incorporated. Research limitations/implications This paper proposes a conceptual model as well as research propositions that need to be validated and confirmed empirically. It advances the research and theory related to quality and quality approaches in a health-care setting. It can enable policymakers, hospital managers to analyze and gauge the appropriateness of quality approaches in a given context before implementing them and could help to improve the introverted quality approaches and quality dimensions currently followed in HCOs (hospitals). Originality/value Contingency framework is a new approach for research on the effectiveness of quality approaches in hospitals. The fundamental idea behind this framework is that effectiveness of quality approaches can be understood best by examining its contingent determinants. Thus, it has the capacity to contribute to the efforts of government and policymakers to make the quality of care affordable to all in India. Essentially, we examine the contexts and variables that determine the effectiveness of quality approaches.

Towards conceptualizing ethical decision-making model in marketing

Purpose This paper aims to present a synthesized conceptual model for ethical decision-making in marketing that accommodates both humanistic and religious aspects. Design/methodology/approach A religious–humanistic approach is adopted on synthesizing. “Ferrell and Gresham’s (1985) contingency framework for ethical decision-making in marketing” and “Al-Ghazali’s ethical philosophy” are considered to be the theoretical base for the synthesized model. Findings Al-Ghazali’s ethical philosophy that stands for the religious dimension in this study was found appropriate for incorporating into the Ferrell and Gresham contingency framework for ethical decision-making in marketing. The approach (religious-humanistic) adopted for synthesizing the two aspects into one model was justified accordingly. Research limitations/implications A newly synthesized model is only conceptually validated. Statistical validity is required based on the variables included in the conceptual model. Future studies are recommended to attain the model fit. Practical implications The scale and model developed in the study should help the marketing-department authorities to assess and evaluate ethical aspects of existing individuals in the organization and potential candidates under the selection stage for employment. The research output derived by way of using the newly synthesized conceptual model should be able to pave the way for more in-depth research on actual ethical practices of “marketing practitioners” in the organization. To some extent, understanding of ethical standing of employees should help in improving efficiency and reduce costs from unethical behaviour. This should be able to improve governance from the top- to the lower-level management. Originality/value To the best of the authors’ knowledge, no literature has conceptualized a model that accommodates both materialistic and religious aspects into a single model to explain ethical decision-making of individuals in organizations. This is an initial and a humble attempt to conceptualize a model that incorporates ethical philosophy in Islam, with special reference to Al-Ghazali’s ethical philosophy.

A critical review on value co-creation: towards a contingency framework and research agenda

Purpose Although a dominant marketing concept, value co-creation (VCC) is not without controversy. Inspired by value co-destruction (VCD), the purpose of this paper is to review the scattered literature on the uncertainties in collaborative value formation, synthesising contingency factors of value outcomes in VCC. Design/methodology/approach The paper is based on an examination of 84 peer-reviewed journal articles. Recognising the drawbacks of the macroscopic abstraction in existing the VCC literature, the authors adopt a zooming-in approach to identify distinct patterns of contingency factors in the collaborative value-formation process. Findings From a macro-social perspective, VCC may connote a sense of exploitation of “consumers” and a need for consumer control of “producers”, impeding harmonious value formation. Zooming into actor-to-actor interactions, the collaborative relationship is found to be a source of uncertainties in value formation, which is further complicated by differences in the knowledge intensities of services. Finally, reviewing the individual consumer reveals a most nuanced picture that demonstrates heterogeneities of consumers’ VCC involvement and complexities in their perceptions and behaviours. Five propositions and a contingency framework are proposed. Research limitations/implications Six value formation mechanisms are proposed based on interconnected and multi-level perspectives, providing implications for managers and future researchers. Originality/value This paper contributes to rebalancing VCC research by synthesising insights on the potential contingencies, which are relatively under-explored yet vital to keep the controversy alive and relevant, and re-invigorating business processes.
