What is Technology?

1. Technology as Objects:
Tools, machines, instruments, weapons, appliances - the physical devices of technical performance

2. Technology as Knowledge:
The know-how behind technological innovation

3. Technology as Activities:
What people do - their skills, methods, procedures, routines

4. Technology as a Process:
Begins with a need and ends with a solution

5. Technology as a Sociotechnical System:
The manufacture and use of objects involving people and other objects in combination

Technology has a number of distinct characteristics:

1. It is Related to Science?
Although there is certainly a relationship between science and technology, there is, except in certain high technology industries, very little technology that could be classified as applied science. Technology is marked by different purposes, different processes a different relationship to established knowledge and a particular relationship to specific contexts of activity. Change in the material environment is the explicit purpose of technology, and not, as is the case with science, the understanding of nature; accordingly its solutions are not right or wrong, verifiable or falsifiable, but more or less effective from different points of view.

2. It Involves Design
At the centre of technology lies design. That “design is the very core of engineering” is affirmed by the requirement that all degree engineering courses should embody it. The design process in technology is a sequential process which begins with the perception of a need, continues with the formulation of a specification, the generation of ideas and a final solution, and ends with an evaluation of the solution.

3. It Involves Making
The motivating factor behind all technological activity is the desire to fulfil a need. For this reason all designs should be made or realised - whether that be through prototype, batch- or mass- production or some form of three-dimensional or computer model - if the need is to be truly fulfilled, the design is to be legitimately evaluated, and the design activity is to have been purposeful and worthwhile.

4. It is Multi-Dimensional
Not only may design and production involve co-operation between different specialisms (between, for example, designer, production engineer and materials scientist), but may involve “technologists” in performing a multitude of functions, such as working with others, operating within budgets, persuading decision makers, communicating to clients and working to deadlines.

5. It Is Concerned With Values
Technology is informed by values at every point. Value decisions may be called for not only in relation to the specific design criteria (i.e. aesthetic, ergonomic and economic judgements, suitability for purpose and ease of manufacture) but also in relation to the rightness or wrongness of a particular solution in ethical terms.
