Information technology and systems justification: A review for research and applications

A structured methodology for assessing and improving e-services in digital cities

“…Extensive research has been conducted for more than two decades concerning Information Systems (IS) evaluation, aiming to formulate methodologies for identifying the full range of positive and negative impacts of an IS (Hirschheim and Smithson, 1988;Smithson and Hirscheim, 1998;Farbey et al, 1999;Irani, 2002;Irani et al, 2006;Gunasekaran et al, 2006). From this research it has been concluded that IS evaluation is highly complex, because the benefits and in general the value created by most categories of IS are multidimensional and complex, both tangible and intangible, financial and non-financial; for this reason it is difficult to decide "what to measure" for the evaluation and "how".…”

ICT-Based Improvement of Construction Procurement Process

“…The problem is not rare in several other sectors [4]. Also, research on productivity increase resulting from ICT in the industry and in the society is of rather recent origin even if it shows that the productivity improvements in ICT services in firms correlate to organizational and process changes [1,2].…”

“…Furthermore, the benefits derived from ICT have been experienced arduous to calculate [3]. The history of ICT implementations is still lacking a positive signal as a mark of successful accomplishment in business improvements [4,5].…”

A Conceptual Framework for Evaluating E Government Systems Success: A Service Ecosystem Approach

“…A number of these frameworks are based on IS success theory which concludes that any comprehensive methodology for evaluating systems should include measurement of a system's effectiveness and efficiency, based on its specific capabilities [9], [10], [7]. Other evaluation frameworks used by governments are based around IS acceptance theory which supports the inclusion of an assessment of the system's usefulness, perceived ease of use, and users' intention to use the technology in the future [11], [12], [13].…”
