Information overload

Introduction

Information overload is assumed to have increased significantly in organizations as a result of the computer revolution from the mid-twentieth century onwards. The situation is thought to have been exacerbated by the expansion of the Internet from academia into the business world, by the development of the World Wide Web and, even more recently, by the explosive expansion of mobile (or cellular) telephony.

However, information overload is nothing new: the potential for overload has existed ever since information became an important input to any human activity. For example, once the scientific disciplines began to clearly emerge in the 17th to 19th centuries, it gradually became impossible for anyone to keep abreast of all of the work in what had been called 'natural philosophy'. Today, in some fields, the degree of specialisation is so high that, even within the same discipline, people are unable to keep abreast of all sub-areas and, in fact, may be completely unable to understand some of them.

Throughout the 20th century, the explosion of information outputs in the form of journal papers, patents, books, 'grey' literature, and so forth continued and that explosion gained even more force in the period immediately following the Second World War. Arguably, it was the release of formerly secret information from both Germany and the Allies that resulted in the birth of information science. More than forty years ago Price showed the exponential growth of scientific journals and of abstracting journals, which constitute a small part of the total information to which a person may be exposed.

What has been recognized in science for many years now affects almost every walk of life: virtually all occupations are, to some degree or other, 'information' occupations and the flood of information from diverse sources, through diverse channels, affects anyone who needs specialised information of any kind in order to function effectively in the world.

Definitions

Wilson has provided definitions of information overload as a personal phenomenon, and as an organizational phenomenon: at the personal level, he defines information overload as:

a perception by a person (or observer) that the information associated with work tasks is greater than can be managed effectively, and a perception that such overload creates a degree of stress for which the coping strategies are ineffective;

and, at the organizational level, as:

a situation in which the extent of perceived individual information overload is sufficiently widespread within the organization as to reduce the overall effectiveness of management operations.

Business factors and information overload

Although information overload is often attributed almost entirely to technological factors but, in fact, the pressures on business are probably equally significant. We can point to globalisation, which increases the volume of communication between different parts of a business; de-regulation of certain industries, which has increased competition and, consequently, the work-loads of employees; out-sourcing, which increases the number of organizations with which a company needs to communicate; and downsizing, which, in spite of being rejected by the management consultant who originally advocated it, is still employed by many businesses as a way of immediately boosting their market value, and which puts increased pressure on the remaining staff.

These factors, coupled with an ethos that encourages long working hours, are probably the primary causes of overload, with the technology being the enabler, rather than the cause.

A Reuters report on the subject also identified some of the effects of overload, specifically:

1. time is wasted - 38% of managers surveyed reported wasting substantial amounts of time looking for information;
2. delayed decision-making - 43% of respondents thought that decisions were delayed or adversely affected by the existence of too much information;
3. distraction - 47% of respondents reported being distracted from their main tasks;
4. stress - leading to tension with colleagues, loss of job satisfaction, ill-health (reported by 42%), reduced social activity (61%), and tiredness (60%)

The role of technology

Information and communication technologies are now the main delivery mechanisms for the management and communication of information in organizations of all kinds. It is not surprising, therefore, to find these technologies blamed for information overload. However, technology is only a tool and overload is caused by the misuse of the technology, rather than by any inherent characteristic. We can add to misuse design characteristics of the software that make misuse easy.

E-mail is one of the prime candidates as a factor in information overload and both misuse and poor design feature in this IT application. Misuse occurs, for example, when individuals use the Reply to all button, resulting in a trivial messaage about, for example, being unable to attend a meeting, being sent to everyone on the mailing list through which the original message was received. Poor design may also be involved here: it would hardly be difficult to present a warning when the Reply to all button was hit, saying, in effect, Do you really want this to go to the 65 people on the mailing list? Poor design also features in relation to attachments, which may be automatically attached to the reply or to a forwarded message, when the content of the message does not require it.

Mobile (cell) phones also feature in the information overload picture. The situation is a little different from e-mail, however; the main problem is that organizational workers in the middle and higher management levels are expected to be always available. As a result, what leisure time they have can be interrupted by phone calls and many managers are afraid to turn off their phones in case they are perceived as not fitting in with the company ethos. In work carried out in a major international bank, Allen and Wilson comment on a staff member who (like all managers at her level) took her mobile phone on holiday, but took her holidays in places like Peru and Nepal, where it was difficult, if not impossible, to recieve a signal.
