Return on Investment in Public Relations: A critical assessment of concepts used by practitioners from the perspectives of communication and management sciences
No full textReturn on Investment (ROI) is a term commonly and non-specifically used by public relations practitioners when discussing the value to be created from communication activities. It mimics business language, particularly from business administration and financial management, but does not figure widely in academic discourse (Watson, 2005).
Although the Institute for Public Relations [now CIPR] undertook a review of ROI practice in the United Kingdom (IPR/CDF 2004) and Likely, Rockland & Weiner (2006) proposed variations of ROI as alternatives to the discredited Advertising Value Equivalence (AVEs) measure of value creation, there has been little discussion other than Macnamara (2007) and Gregory and Watson (2008).
This paper gives an overview on the views of ROI in public relations literature and concepts used by agencies and providers of measurement services. It reports on survey research amongst practitioners in several European countries on identifying the economic value of public relations. The findings are compared with the concepts of ROI used in business and accounting literature (Weber and Schäffer, 2006; Drury, 2007).
Applied theory and parameters for the development of measurement and evaluation techniques are proposed. The paper concludes that the use of the term ROI in public relations needs a proper foundation in overriding management theory; otherwise PR theory and practice will discredit themselves
An initial investigation on the use of ‘Return on Investment” in public relations practice
No full text‘Return on Investment’ (ROI) is usually defined in management literature as a measure of financial effectiveness that is concerned with the returns on capital employed in business (profit-making) activities. In public relations practitioner parlance, however, ROI appears to be used in a much looser form to indicate the results of activity. This mixed method research using an online survey instrument investigated practitioner understanding of the term, primarily in the UK. These findings resulted: 1) Two-thirds of PR practitioners use the term ROI when planning and evaluating communication activity; 2) ROIs related to communication objectives (66.7%) are more widely used than financial-related ROIs (12.8%); 3) There is a clear difference in ROI practices between consultants/freelances and in-house colleagues. Nearly three-quarters of consultants and freelances (73.1%) offer an ROI formula to clients but only 26.3% of in-house practitioners have one; and 4) On the oft-discussed question of an industry-wide ROI formula, only 35.6% supported the proposition with 64.4% opposed. However, the survey also found that practitioner concepts of ROI are very narrowly expressed, mainly in relation to media outputs

The Use of Return on Investment (ROI) in the Performance Measurement and Evaluation of Information Systems
No full textPerformance measurement and program evaluation are essential for accountable and transparent delivery of public services to Ontarians. Evaluation of the existing information systems and making investment decisions on new acquisitions should be based on a rigorous and quantifiable analysis of the benefits and costs. Return on Investment (ROI) is arguably one of the most popular metrics, and ROI analysis (when applied correctly) is a powerful tool in making informed decisions. This presentation explores a wide variety of the approaches to calculating ROI of an information management system. Attendees will find practical answers to the questions: What is ROI? What types of ROI exist? What are the benefits of using ROI metrics? What are the limitations of the ROI approach? In this session, several concrete examples of the application of the ROI will be reviewed. Although the focus of the presentation is made on the information systems/solutions, most considerations of ROI use are generic and applicable in any field
Appropriate Similarity Measures for Author Cocitation Analysis
No full textWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Towards an evaluation framework for medical web applications
No full textCopyright @ 2013 EMCIS.The main aim of this study is to review and analyse various evaluation frameworks used to assess the operational effectiveness of various Information Technology (IT) processes/applications and identify their strengths in order to form a new holistic framework for economic evaluation of web applications. This research aims to address the need for a new holistic evaluation framework for the purpose of the evaluation of the medical web applications. Over the last decade more and more, companies used accountancy techniques such as the frameworks analysed in this research. This new holistic framework that was developed will include also steps regarding the indirect and intangible costs and benefits identification and their incorporation in the evaluation process. Moreover the new emerging market of the medical websites and the embedded on them web applications requires also a new evaluation framework that will provide accurate results in the estimation of the efficiency of an investment on them. The paper first presents an introduction about why economic evaluation is important when evaluating the Information Technology in organizations. Various studies are reviewed, which highlight the ever increasing importance of integrating economic evaluation processes, such as Cost Benefit Analysis (CBA) and Return on Investment (ROI), into systems and processes of organizations and economic organizations, and analyse the factors that govern their role. Finally, the evaluation frameworks and methods that are found in these studies should be used as a part of a proactive systematic action plan that the organizations could use to avoid budget reduction due to incorrect planning. The next part of this study includes a comprehensive presentation and review of past frameworks used to evaluate Information Technology. The frameworks that are reviewed are the Framework for evaluation of information systems, the Information Technology Adoption Model (ITAM), the Total Evaluation and Acceptance Methodology (TEAM) framework, the ROI Process Model and HOT-fit evaluation framework for Health Information Systems

"Closing the R&D Gap, Evaluating the Sources of R&D Spending"
No full textBoth spending and tax policies have been implemented in the United States with the goal of stimulating private sector research and development (R&D). Karier questions whether current R&D policy, especially the research and experimentation tax credit, can contribute to closing the gap between nondefense expenditures on R&D in the United States and such expenditures in other countries, such as Japan and Germany. He also explores possible changes to our current R&D policy to make it more effective.
