Читать книгу Decision Intelligence For Dummies - Pamela Baker - Страница 32

You may be wondering how the processes in decision intelligence differ from those used in data analytics. After all, it’s obvious that decisions are also made first when using data analytics in the usual way. For example, someone decides what the business rules are before they apply them to data analytics or AI. Someone also decides what data to use, what data sources to join, and what queries to make. Further, someone decides what projects to launch and whether to send them to production. And so on.

With all these decisions upfront, what does “Put the decision first” in decision intelligence mean? And how does it change anything? It helps to remember that the process in machine-based decision-making is linear, meaning that it moves consecutively from data preparation and selection to algorithm inputs and, finally, to an output. The output is typically an insight or a recommendation delivered as a visualization, as narrative text, or as both, from which a human can decide what action to take. Sometimes, the output is connected to an automated process that then takes an action as directed by the output.

In any case, the path is a straight line.

Now tilt that line upward so that it’s the first leg of an inverted V. At the bottom is the starting point, which is the data to be analyzed. At the top is the decision to be made based on the analyses. That’s your path upward.

Ignore that path and work your way back down from the decision to the data. Rarely will you follow the same path down. Instead, you’ll create a different path that will be more specifically tied to the decision. The two paths together resemble an inverted V.

The first leg of the inverted V begins with mining the data, and then an analysis follows. If you think about it, this process is now defining the decisions you can make. By contrast, in the V's second leg, the decision is defining the data, tools, and queries.

The first leg is a discovery mission. The second is a mission with a purpose.

Which leg do you think will consistently deliver a payload?

And that, my friend, is why and how you put the decision first.
