Although Ackoff did not present the hierarchy graphically, he has also been credited with its representation as a pyramid. In the same year as Ackoff presented his address, information scientist Anthony Debons and colleagues introduced an extended hierarchy, with "events", "symbols", and "rules and formulations" tiers ahead of data. In Nathan Shedroff presented the DIKW hierarchy in an information design context which later appeared as a book chapter.
Jennifer Rowley noted in that there was "little reference to wisdom" in discussion of the DIKW in recently published college textbooks ,  and does not include wisdom in her own definitions following that research. The DIKW model "is often quoted, or used implicitly, in definitions of data, information and knowledge in the information management , information systems and knowledge management literatures, but there has been limited direct discussion of the hierarchy".
This has led Israeli researcher Chaim Zins to suggest that the data—information—knowledge components of DIKW refer to a class of no less than five models, as a function of whether data, information, and knowledge are each conceived of as subjective , objective what Zins terms, "universal" or "collective" or both. In Zins's usage, subjective and objective "are not related to arbitrariness and truthfulness , which are usually attached to the concepts of subjective knowledge and objective knowledge".
Information science , Zins argues, studies data and information, but not knowledge, as knowledge is an internal subjective rather than an external universal—collective phenomenon. In the context of DIKW, data is conceived of as symbols or signs , representing stimuli or signals,  that are "of no use until In some cases, data is understood to refer not only to symbols, but also to signals or stimuli referred to by said symbols—what Zins terms subjective data. This distinction is often obscured in definitions of data in terms of " facts ". Rowley, following her study of DIKW definitions given in textbooks,  characterizes data "as being discrete, objective facts or observations, which are unorganized and unprocessed and therefore have no meaning or value because of lack of context and interpretation.
Insofar as facts have as a fundamental property that they are true , have objective reality, or otherwise can be verified , such definitions would preclude false , meaningless, and nonsensical data from the DIKW model, such that the principle of garbage in, garbage out would not be accounted for under DIKW.
American information scientist Glynn Harmon defined data as "one or more kinds of energy waves or particles light, heat, sound, force, electromagnetic selected by a conscious organism or intelligent agent on the basis of a preexisting frame or inferential mechanism in the organism or agent. Information is the meaning of these sensory stimuli i. For example, the noises that I hear are data. The meaning of these noises e. Still, there is another alternative as to how to define these two concepts—which seems even better. Data are sense stimuli, or their meaning i.
Accordingly, in the example above, the loud noises, as well as the perception of a running car engine , are data. Bold in original. Subjective data, if understood in this way, would be comparable to knowledge by acquaintance , in that it is based on direct experience of stimuli. However, unlike knowledge by acquaintance, as described by Bertrand Russell and others, the subjective domain is "not related to Whether Zins' alternate definition would hold would be a function of whether "the running of a car engine" is understood as an objective fact or as a contextual interpretation.
Whether the DIKW definition of data is deemed to include Zins's subjective data with or without meaning , data is consistently defined to include "symbols",   or "sets of signs that represent empirical stimuli or perceptions ",  of "a property of an object, an event or of their environment". Boulding's version of DIKW explicitly named the level below the information tier message , distinguishing it from an underlying signal tier. Zins determined that, for most of those surveyed, data "are characterized as phenomena in the universal domain".
In the context of DIKW, information meets the definition for knowledge by description "information is contained in descriptions "  , and is differentiated from data in that it is "useful". Rowley, following her review of how DIKW is presented in textbooks,  describes information as "organized or structured data, which has been processed in such a way that the information now has relevance for a specific purpose or context, and is therefore meaningful, valuable, useful and relevant.
In his formulation of the hierarchy, Henry defined information as "data that changes us",   this being a functional, rather than structural, distinction between data and information. Meanwhile, Cleveland, who did not refer to a data level in his version of DIKW, described information as "the sum total of all the facts and ideas that are available to be known by somebody at a given moment in time". American educator Bob Boiko is more obscure, defining information only as "matter-of-fact".
Information may be conceived of in DIKW models as: i universal, existing as symbols and signs; ii subjective, the meaning to which symbols attach; or iii both. Zeleny formerly described information as "know-what",  [ citation needed ] but has since refined this to differentiate between "what to have or to possess" information and "what to do, act or carry out" wisdom.
To this conceptualization of information, he also adds "why is", as distinct from "why do" another aspect of wisdom. Zeleny further argues that there is no such thing as explicit knowledge , but rather that knowledge, once made explicit in symbolic form, becomes information. The knowledge component of DIKW is generally agreed to be an elusive concept which is difficult to define. The DIKW definition of knowledge differs from that used by epistemology. The DIKW view is that knowledge is defined with reference to information. Zins has suggested that knowledge, being subjective rather than universal, is not the subject of study in information science , and that it is often defined in propositional terms,  while Zeleny has asserted that to capture knowledge in symbolic form is to make it into information, i.
Knowledge is a fluid mix of framed experience, values, contextual information, expert insight and grounded intuition that provides an environment and framework for evaluating and incorporating new experiences and information.
It originates and is applied in the minds of knowers. In organizations it often becomes embedded not only in documents and repositories but also in organizational routines, processes, practices and norms. Mirroring the description of information as "organized or structured data", knowledge is sometimes described as:. One of Boulding's definitions for knowledge had been "a mental structure"   and Cleveland described knowledge as "the result of somebody applying the refiner 's fire to [information], selecting and organizing what is useful to somebody".
Zeleny defines knowledge as "know-how"   i. We also concealed our private selves behind our job titles.

Gerry did not seem to mind. I did. I was no longer in a family of companions but in a complicated network of boxes called an organization, a machine for organizing work. I did not enjoy being part of a machine. The good news today is that many of those jobs no longer exist.

The new technology does it all. Nobody should regret that. You would never have enjoyed the job that I had any more than I did. Nevertheless, large organizations will still continue to exist in some form, and that poses a challenge. Humans should only be used to do what humans do best: coming together to get things done as sensibly and creatively and effectively as possible. The technology should not try to do what humans do better, and vice versa. We combine best in families, even when we disagree, and in villages of families. Great cities are collections of villages that in turn are collections of families.
Why are villages and platoons better than mass organizations?
Because they are human scale: They allow you to be a person, not a cog. Professor Robin Dunbar has studied a wide range of human groups down the ages, from early society to the modern day. He has come up with the Dunbar number: It has been for as long as we have been a species. In my experience, is pushing it. We may have just five people whom we know intimately and trust implicitly: our best friends. At the next levels, there are 15 good friends or mates whom we are always delighted to be with, 45 whom we see occasionally, perhaps work with, and that make up our Christmas card or Facebook list of friends.
I have found that for me, 45 works best as the maximum size of a work group. You will now start to introduce specializations and departments; you will become more bureaucratic, a machine.
Last but not least…
We need large organizations — now more than ever, as the world increasingly becomes one big marketplace. Oil companies such as Shell, car manufacturers, pharmaceutical businesses, steelworks, and many others like them have to employ a lot of people to get the work done. The new giants such as Facebook only work if everyone signs up to them, so they swallow up competitors as soon as they appear.
The winner takes all. Can these city-like organizations restructure themselves into collections of villages that are linked together by the new information technology? My guess is that the organizations will have to start doing just that if they want to attract the best and brightest of the new generation. Already young people are turning away from the traditional pyramid organizations in which you clamber your way up the hierarchy over the years.
The world of work is increasingly going to realize that small is better.

Such organizations already exist. Small startups keep things small, until they become successful. But large organizations are also trying. Haier, in China, employs more than 70, people. It makes things, physical things like refrigerators, ovens, domestic equipment, things that might seem ripe for industrial-style mass organization.
But Haier is largely made up of 2, autonomous groups. These groups of seven to 10 people organize their own work, and if they can make improvements or boost their sales, they can keep some of the savings or profit. I am a great believer in the federal principle as the best way for all organizations, business as well as political, to grow big while keeping their bits small. Federalism does not mean centralization, but the reverse. Its dominating principle is subsidiarity, an ugly term that effectively means reverse delegation — in that power is considered to lie in the small parts of the organization, which then delegate to the center only the things that the center can do better for them all.
It is the only way that a city of small villages can work. Young people today often start off their working lives in an organization, be it in business, government, or the charity sector. That is sensible, for a time. I see such organizations as the graduate schools for work.
