Reactions to contract loss are yet to be properly studied in public procurement.\u0000\u0000\u0000Design/methodology/approach\u0000The hypothesis is that contract loss triggers a five-stage grieving process, as predicted by the Kubler-Ross model. The hypothesis is tested using the recent UK passport contract in which the British supplier, De La Rue, lost to the Franco-Dutch supplier, Gemalto. Secondary data from corporate publications, news reporting, parliamentary debates and trade union press releases is used to compile the case.\u0000\u0000\u0000Findings\u0000The findings show that De La Rue and its supporters passed through the five stages of grief in response to their loss. De La Rue initially exhibited denial by vowing to appeal the decision. Next came anger directed at the UK Government. An attempt to bargain was made during the standstill period. Depression set in after De La Rue admitted it would not appeal. Finally, acceptance was indicated by De La Rue pursuing new opportunities in the product authentication market.\u0000\u0000\u0000Research limitations/implications\u0000The study is based on a single case.

To capitalize on successful innovative instruments, it is essential that these are reused. However, reuse can be problematic in project-based public client organizations. This paper aims to apply the ambidexterity concept of integration mechanisms to examine how such reuse can be facilitated. Design/methodology/approach - An initial framework is developed to conceptualize and contextualize the ambidexterity integration mechanism for the procurement function of a multi-project public client. Concluding that, in this situation, an organizational procedure is an appropriate interpretation of the integration mechanism, a design science project is carried out to develop and implement a procedure in a real-life setting. Findings - Reconstructed reuse patterns confirm the need to have an actionable integration mechanism implemented. Integration, in the sense of drawing benefits from successful one-off innovative procurement instruments, may fail unnoticed if not organized and deliberately managed. The procedure developed in the design science project demonstrates how such integration can be achieved. Originality/value - Although research on ambidexterity has grown exponentially in the past decade, it is yet to be applied in the field of public procurement. Furthermore, the application of design science research is novel in this field of literature. The paper illustrates how both can help solve a relevant organizational problem.","PeriodicalId":45136,"journal":{"name":"Journal of Public Procurement","volume":"20 1","pages":"1-19"},"PeriodicalIF":2.5,"publicationDate":"2019-11-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1108/jopp-08-2019-0052","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43923578","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Andayani","doi":"10.1108/jopp-02-2019-0012","DOIUrl":"https://doi.org/10.1108/jopp-02-2019-0012","url":null,"abstract":"PurposeThis paper aims to discuss the factors that cause individuals to commit fraud, especially in the public procurement context. All this time, an empirical review of public procurement fraud has only focused on the macro and micro level, as well as its losses on the country's economy. This paper highlights individuals’ fraudulent behavior from the four elements of the fraud diamond theory, namely, pressure, opportunity, rationalization and capability.Design/methodology/approachThis paper is a literature review that discusses the fraudulent behavior of bureaucrat as a procurement official in the context of public procurement. This review uses fraud diamond theory as its theoretical framework to explain the attributes to do fraud.FindingsPublic procurement is a high-risk area for fraud (corruption), particularly in the government institution. It cannot be denied that the situation factor (pressure and opportunity) will interact with psychological aspects (rationalization) and individual capability to direct the individuals to commit fraud. This study discusses how existing pressure (motivation) and opportunities are used by individuals who have the capability to rationalize their actions. This literature review also endeavors to shed light on the strategy to prevent, detect and control the causes of fraud.Practical implicationsThis paper provides an understanding of regulators, auditors and other employees in recognizing the characteristics and nature of fraud antecedents. This understanding can help prevent various forms of procurement fraud that occur within their organizations. This paper also can be a guideline to assist public sector organizations in designing effective internal control systems to prevent fraud in the process and practice of public procurement.Social implicationsPublic procurement has a central role that enables the government to allocate the budget effectively and efficiently. Compliance in implementing procurement rules and procedures will improve the quality of public services.Originality/valueThere exists relatively little study outlining the factors underlying of bureaucrats’ (procurement official) opportunistic behavior on procurement activities. The authors focused on bureaucrats’ behavior because they have unique positions of power and responsibility of the procurement process. On the one hand, they have a crucial role in serving the public and safeguarding public assets. On the other hand, they have the ability to collaborate with politicians and business actors in corrupt procurement practices. Therefore, the discussion on this topic is very relevant and interesting.","PeriodicalId":45136,"journal":{"name":"Journal of Public Procurement","volume":" ","pages":""},"PeriodicalIF":2.5,"publicationDate":"2019-11-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1108/jopp-02-2019-0012","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43579796","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

At first, this paper highlights some critical issues regarding the weighted sum model (WSM) and the algorithms frequently used to evaluate the most economic advantageous tender. Then, it proposes to extend the AHP approach to the evaluation of both the qualitative and quantitative components of a public procurement award. Finally, the WSM and the AHP are applied to the same case study to show, step by step, some criticisms of the former and some advantages of the latter.\u0000\u0000\u0000Design/methodology/approach\u0000This paper proposes to apply two AHP models to evaluate both qualitative and quantitative components of a public tender.

The model integrates multiple qualitative and quantitative criteria, simplifies the selection process, achieves optimal use of funds and leads to cost savings. It allows to reduce the discretional power of both the contracting issuer, in the choice of the formula to adopt for calculating the coefficients, and the committee members, allowing tender evaluation to have more trust and ensure the fairness of public procurement matters and quality of the object purchased.\u0000\u0000\u0000Originality/value\u0000This paper proposes the use of two hierarchical models to evaluate qualitative and quantitative requirements and provide the ranking among several tenders.\u0000","PeriodicalId":45136,"journal":{"name":"Journal of Public Procurement","volume":" ","pages":""},"PeriodicalIF":2.5,"publicationDate":"2019-09-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1108/JOPP-05-2018-0020","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45702048","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
