Abstract: While the productivity paradox has now been officially pronounced dead, the argument and the evidence for this assertion are both at a macroeconomic level. What has been less closely examined is the microeconomic impact of recent developments in ICT on the productivity of office and knowledge workers. There is an assumption, readily seen in many advertisements for mobile technology, that multi-tasking, WiFi connected laptops, Blackberrys, smart phones and so on are good for business and make people more effective and productive. This may be true some of the time and there is some (albeit limited) research which supports claims that these technologies increase productivity. However there are also emerging concerns that, in certain environments, these technologies may actually reduce productivity in both the short and the long term. This paper examines this problem and research to date and proposes a framework for further investigation of this phenomenon.
Keywords: multitasking, multicommunication, productivity, effectiveness, efficiency, ICT evaluation.

1.1 A multitasking world
In October 2007 a video entitled “A Vision of Today’s Students” was posted on Youtube1. The video includes a series of views of students in a contemporary lecture theatre. As the camera turns to each student in turn, he or she holds up a card or a laptop showing a personal message such as “I spend three and a half hours a day on-line” or “I will read 8 books this year”. One such card simply says “I am a Multi-tasker”.
In another video in the same vein, a black and white photograph of an old fashioned classroom from early in the last century is shown. The accompanying text argues that the type of learning depicted was designed for people who

    “Of all forms of mental activity, the most difficult to induce even in the minds of the young, who may be presumed not to have lost their flexibility, is the art of handling the same bundle of data as before, but placing them in a new system of relations with one another by giving them a different framework, all of which virtually means putting on a different kind of thinking-cap for the moment. It is easy to teach anybody a new fact…but it needs light from heaven above to enable a teacher to break the old framework in which the student is accustomed to seeing.”…

Switching between tasks takes more time than repeating the same task.…

    In today’s world, are their any viable options to multitasking? We have become quite adept at juggling projects, emails, phone calls, and social media in our daily lives. Much research has been conducted, and many studies have come to the conclusion that multitasking lessens one’s overall effectiveness. David Silverman, in his essay “In Defense of Multitasking” presents and opposing side to this contention. Silverman, a Harvard Business Review blogger, goes so far as to likening our seemingly primal need to multitask to our necessity to breathe air (539). While it may not prove to be as vital as oxygen, Silverman demonstrates how crucial it is for the workplace.…
