The metallurgy of zinc-coated steel - ScienceDirect

By now it is obvious that technology consists both of hardware and software. Hardware components include capital and intermediary goods, such as industrial products, machinery, equipment, buildings, workplaces and physical layouts, most of which chiefly concern the micro-ergonomics domain. Software pertains to programming and planning, management and organizational techniques, administration, maintenance, training and education, documentation and services. All these concerns fall under the heading of macro-ergonomics.

P versus NP problem - Wikipedia

People belonging to a certain professional category may use a piece of technology in a specific fashion. Wikström et al. (1991), in a project aimed to develop hand tools, have noted that despite the designers’ assumption of how plate shares are to be held and used (i.e., with a forward holding grip and the tool moving away from one’s own body), the professional tinsmiths were holding and using the plate share in a reversed manner, as shown in . They concluded that tools should be studied in the actual field conditions of the user population itself in order to acquire relevant information on the tools characteristics.

The issue of efficacy is always the point of departure in the modification of tools or machines, and is often related to the costs devoted to the modification in question, the technical features to be addressed, and the functional changes to be embodied in the new design. Comfort and attractiveness are qualities that by no means deserve to be neglected among these other characteristics.

Calculus I ("hedva aleph") - University of Haifa

Unfortunately, many electronically generated displays have been fuzzy, often overly complex and colourful, hard to read, and required exact focusing and close attention, which may distract from the main task, for example, driving a car. In these cases the first three of the four “cardinal rules” listed above were often violated. Furthermore, many electronically generated pointers, markings and alphanumerics did not comply with established ergonomic design guidelines, especially when generated by line segments, scan lines or dot matrices. Although some of these defective designs were tolerated by the users, rapid innovation and improving display techniques allows many better solutions. However, the same rapid development leads to the fact that printed statements (even if current and comprehensive when they appear) are becoming obsolete quickly. Therefore, none are given in this text. Compilations have been published by Cushman and Rosenberg (1991), Kinney and Huey (1990), and Woodson, Tillman and Tillman (1991).

A company’s organization, its structure, value system, function, behaviour, and so on, are largely cultural products of the society in which it operates. This means that what happens within an organization is mostly a direct reflection of what is happening in the outside society (Hofstede 1983). The prevailing organizations of many companies operating in the IDCs are influenced both by the characteristics of the technology producer country as well as those of the technology recipient environment. However, the reflection of the societal culture in a given organization can vary. Organizations interpret the society in terms of their own culture, and their degree of control depends, among other factors, on the modes of technology transfer.

In looking at the process of systems design, including participative processes, Hirschheim and Klein (1989) have stressed the effects of implicit and explicit assumptions of system developers and managers about basic topics such as the nature of social organization, the nature of technology and their own role in the development process. Whether system designers see themselves as experts, catalysts or emancipators will greatly influence the design and implementation process. Also, as mentioned before, the broader organizational context in which participative design takes place has to be taken into account. Hornby and Clegg (1992) provided some evidence for the relationship between general organizational characteristics and the form of participation chosen (or, more precisely, the form evolving in the course of system design and implementation). They studied the introduction of an information system which was carried out within a participative project structure and with explicit commitment to user participation. However, users reported that they had had little information about the changes supposed to take place and low levels of influence over system design and related questions like job design and job security. This finding was interpreted in terms of the mechanistic structure and unstable processes of the organization that fostered “arbitrary” participation instead of the desired open participation (see ).
