Reference excerpt

J. Donald R. de Raadt (born 1946) is a Swedish organizational theorist and Professor Emeritus in Informatics and System Science at Luleå University of Technology.

Biography J. Donald R. de Raadt studied Economics and Politics at the University of Queensland, where he received a Bachelor of Arts, and later studied at the Royal Melbourne Institute of Technology where he first obtained his post-graduate Fellowship Diploma in Management and then his Masters in Business. He obtained a Ph.D. in Sociology from La Trobe University, Melbourne. Over a period of fourteen years, he worked in information systems and corporate planning for a shipbuilder, two computer manufacturers and an insurance company. Prior to taking his present appointment in Sweden, he has held academic posts at the Royal Melbourne Institute of Technology in Australia and at Idaho State University in the USA. He was conferred the title of professor by the Swedish government in 1992 and held a chair in Informatics and System Science at Luleå University of Technology for twelve years until 2004. He has served as president of the International Society for the Systems Sciences from 1994–1995, and of the Swedish Operational Research Society, and vice-president of the International Federation for Systems Research in Vienna. In 1985 he received the Sir Geoffrey Vickers Memorial Award of the Society for General Systems Research and in 1988 he was selected as the outstanding researcher of the College of Business at Idaho State University.

Publications He is the author of several books and articles. A selection:

Worked examples

Example 1 — a first encounter with J. Donald R. de Raadt

Start with the simplest possible case. Write down what J. Donald R. de Raadt claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In astronomy, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to J. Donald R. de Raadt before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about J. Donald R. de Raadt ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of J. Donald R. de Raadt

In research: J. Donald R. de Raadt appears in astronomy research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses J. Donald R. de Raadt in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: J. Donald R. de Raadt is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1946 births, Academic staff of the Luleå University of Technology, Idaho State University faculty, so understanding it makes those chapters shorter.
In everyday life: Look for J. Donald R. de Raadt outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
