It shows that with a digital wallet all the other aspects of payment, e-invoicing, marcom (marketing and communications) etc. (Whether we already know by some immediate insight or that our insight is mediated by living a certain way, having a certain form of life with certain doings and rituals is far beyond the scope of this out-of-the-blog). If you think of it really all definitions are circular and the fact we understand circular definitions means we can already understand what is at stake and that the definition only makes explicit what we already know. I do not mean by circular that most Venn diagrams use circles (forgetting triangles, squares etc.), but that it seems you define an X by using X in a definition. Rather than writing a very long ‘out-of-the-blog’ in which I will define a Venn diagram it is better to show what a Venn diagram is by defining a Venn diagram with a Venn diagram. The sense of a Venn diagram is given and three practical tips to make your own Venn diagram. A new way to present companies via an organi-venn-diagram is introduced. Examples are given of the innovation method TRIZ, the payment industry, the holy versus the sacred, big data, innovation, e-invoicing B2C via e-mail and data logistics.Ī test in the form of a Venn diagram is given by which you can test whether you are a dweep, geek or nerd. You will learn step-by-step what a Venn diagram is by being shown Venn diagrams of two, three, four and five sets. On the square trail beyond a Venn diagram: a dweep-geek-nerd-test Equally, however, it could be argued that the blurred lines between categories and objects, sets and the data points within them has made the multiples uses of Venns confusing and contradictory.Three sacred circles on the holy digital walletįour innovative circles on big data tooling Is ‘cubic equation’ an object or a category? Is it as simple as whether it is plural or singular?Īs with language, we would expect the field of data representation (to some extent) to shift, evolve and change meaning over time, and there is no reason why ‘Venn diagrams’ needs to go the way of Cornish pasties – reserved only for a very specific selection of objects to maintain particular boundaries. What’s interesting here is that the distinction we made earlier between objects and categories which seemed pretty clear-cut then, now might not seem so obvious. (I maintain that ‘marmalade’ goes inside ‘jam’ in the same way, but some readers may disagree.)

For example, if we drew a large circle to represent ‘equations’, then the circle representing ‘cubic equations’ would go entirely inside it, as there cannot exist a cubic equation that isn’t part of the larger category of equations. What we call Venn diagrams also now usually covers Euler diagrams, which is a similar concept but contains concentric sets – the idea of categories-within-categories. The second kind, often used in English or other humanities lessons, is the contrast and compare use, where the circles represent things, and the categories (or attributes/properties of that category) are put inside them.

One type of Venn diagram – the classification use – is often used in maths lessons, and asks pupils to put things inside the circles and label the circles themselves as categories (or attributes/properties of that category). When questioned, both teachers and pupils were unaware of these differences or complexities, or even that there were two types of common use. Kimmins and Winters (2015) 1 identified this with great clarity: Venns are being used in two very different ways – often both alongside one another – with primary-age children, and often without any explicit attention drawn as to their different uses. ‘It’s not just a thing plus a thing gives another thing.’ ‘For it to work, the thing in the middle has to belong to both categories,’ says Anna.
