ABSTRACT. Guided by a conceptual model developed by Davison and Wright, the research was conducted to determine which types of contract administration problems (e.g., delays) were perceived as most likely for seven types of contracts (e.g., small supplies and purchases). The survey was sent electronically to all members of the National Institute of Government Purchasing (NIGP). Postcards with the survey URL were also distributed to a random sample of members of the Institute for Supply Management (ISM). Data were obtained from 557 respondents. The results for the perceived relationship of the occurrence of contract administration problems for the various contract types provided partial support for the The results also showed that construction contracts were perceived as having the most problems overall and delay was perceived as the most common contract administration problem. The implications and limitations of the research are discussed.

ABSTRACT. The main purpose of this paper is the evaluation of previous German and Spanish research conducted related to oral communication capability in a different cultural surrounding. In order to test the validity of the European findings, a new sample was drawn using membership data of the U.S. based National Institute of Governmental Purchasing. The results of this paper corroborate that oral communication capability is a construct consisting of three dimensions. The model obtained in Europe for managers from private sector purchasers is also applicable in the U.S. for public purchasers. Furthermore, European results proposed four distinct types of communicators, while in the U.S. two additional groups of purchasers were found. Nevertheless, there is limited evidence for demographic or cultural influences on the oral communication capabilities of purchasers.

ABSTRACT. The aim of the present paper is to model the vendor selection process in construction projects in Greece. The applied approach involves a multicriteria rating technique used for calculating a normalized economic bid for the alternatives (i.e. vendors) by determining a proposed multiplier coefficient. This technique uses two stage compromise programming procurement criteria and weights according to the relevant legislative framework for government procurement to provide a multicriteria value score for each vendor. The application of the approach is demonstrated by an illustrative example concerning the procurement of earthmoving equipment (i.e. bulldozer). The primary advantage of this approach is that it incorporates a degree of subjectivity into the evaluation process in compliance with the existing legislative framework.

ABSTRACT. The extant literature provides very little insight into the way in which public purchasing departments are contributing to competitive acquisition processes for consulting services. This research attempts to address this shortcoming by describing the way that public purchasing departments have been able to contribute to these decisions throughout the various stages of the acquisition process. Study informants included 1782 public purchasers from federal, state, provincial, and local government agencies throughout the United States and Canada. While the purchasing department is involved in these important purchase decisions, it would seem that their respective agencies might benefit from increased involvement and consequently the value that can result.

ABSTRACT. The literature suggests public procurement professionals have different perspectives on supply chain management (SCM) vis-à-vis their private sector counterparts. Based on a recent survey of Canadian purchasers, this paper presents an empirical comparison of public vs. private views on SCM. The questionnaire is structured around a set of 54 topics, tools and techniques; along with four perspectives on the relationship between purchasing and SCM. Important findings from this survey of SCM professionals include: (1) public procurement professionals have narrow perspectives on SCM compared to their private sector counterparts; and (2) public sector professionals have different perceptions regarding the importance of topics, tools and techniques to support their performance on the job.
