The fundamentals of management information – P

Pfeile

Gängiges Symbol für Veränderung, einfach, aber auch vergröbernd. Versteht man schnell, man geheimst aber auch gerne mehr hinein, einen Trend nämlich. Bella hat das schon kritisiert. Wir finden es meist genauso verständlich und nützlicher, die Veränderung in Prozent hinzuschreiben. In DeltaMaster stehen Pfeile tatsächlich für Trends, die das System automatisch errechnet und in unterschiedlichen Neigungen des Pfeils ausdrückt.


Planung

Ausdruck unternehmerischen Willens bei aktiver Marktbearbeitung. DeltaMaster trägt zu einer Verzahnung von Analyse, Planung und Reporting bei, mit Funktionen wie Dateneingabe, „Splashing“, Wertweitergabe, Kommentaren u. Ä. Simple Workflow-Funktionen stellen vernünftige Teamarbeit und die richtige Reihenfolge der Planungsschritte sicher.


Portfolioanalyse

Segmentierung von Geschäftseinheiten, Produkten, Kunden, Vertriebsregionen o. Ä. nach zwei Kennzahlen, welche die X‑ bzw. Y-Achse einer Vierfeldmatrix bilden. Ursprünglich von der Boston Consulting Group mit relativem Marktanteil, relativem Marktwachstum und Normstrategien je Segment vorgeschlagen. Eines der betriebswirtschaftlichen Standardverfahren in DeltaMaster, ausgestattet mit vielen Extras für tiefergehende Analysen. Zum Beispiel kann man die Segmentierung als virtuelle Hierarchie speichern.


Perception

More mysterious than you might think because it hides its tricks from us. For example, we see things clearly and colorfully only in sections the size of a thumbnail at arm’s length. The limitations of perception make → visualization tricky, unless we consciously use these limitations to steer the eye to where we want it to look. This requires the right visualization and → AI, the latter being needed to determine – with the aid of data-based algorithms – where it makes sense to guide the eye to. → Graphical Tables and our Bissantz’Numbers provide the right visualization.


Pattern recognition

The human ability to rapidly process simple visual signals and recognize new relationships even when they are incomplete or blurry. In this regard, humans are still superior to machines. DeltaMaster combines the strengths of both man and machine by choosing the highest possible level of automation for all sub-steps that can be delegated to the computer and using graphical forms that support and facilitate the recognition of peculiarities. Some algorithms even simulate the human recognition process.


Percentages

Values expressed as a fraction of 100 to facilitate comparisons. We encounter percentages as margins, rates, and shares. We say: who cares about relative values? Sorting tables by margins and rages instead of absolute values, highlighting relative values in charts, or use them solely in tables in place of absolute values is dangerous. Margins and rates direct your attention to effects that are not very relevant or have a small base. They only appear to make things comparable. This, in turn, has to do with the fact that they reference themselves. Shares are slightly different because you usually know the sum which they reference. In DeltaMaster, graphic tables provide an elegant solution for some of these problems. Bars for absolute values show the relative meaning of one object in comparison to the others without needing a special percentage calculation.


Perspective Priority

A concept that we felt was missing in the theory of perception so that we could define basic → integrity rules. In the case of lines, you primarily notice how steep or flat they run. In bars or columns, however, it is the sheer length. Dot lines, in comparison, are similar to columns but work like lines. And there are rules which you can derive from all of that – for example, that you should not chop off the bottoms of columns and generally apply a logarithmic scale to lines. When generating charts, DeltaMaster automatically applies built-in rules of integrity so that the user doesn’t have to worry about perspective priority.


Pie chart

A commonly used, yet heavily chastised chart form. As the visualization expert Edward Tufte once said, „The only worse design than a pie chart is several of them.“ Generally speaking, you should only use a pie chart when the data displayed actually represents a whole. Yet even that rule is frequently ignored. It is difficult to intuitively compare different-sized pieces of the pie. Since they are difficult to label, the human eye has to jump back and forth in order to read them. When they are well done, pie charts – even several of them – can be an attractive, easy-to-understand visualization form. That is why DeltaMaster offers them as a component of → graphic tables. Pie charts have a bad reputation because people commonly use them in scenarios where bars would have been the better alternative. Bella has already howled about that many times.
