Female Instincts vs. Quantum Entanglement

The  pivot role of a wild savant woman in the midst of revolutions and enlightenment: Emilie du Châtelet from my summer book Passionate Minds of David Bodanis, Three Rivers Press N.Y, 2006. I am impressed by Emilie ‘ insights permeated into the scientific mainstream with her unconventional but logic thoughts, so original that her male scientists recycled her ideas even forgot who had originated them. Emilie du Châtelet contributed the square to Einstein concept of energy…

The Merging of Social Media, Big Data, Perpetually Connected Consumers and AI... Nirvana, or the End of Free-Will?

The Not So Distant Future

It’s Friday September 14, 2046, and you are at the airport getting an alert from your car that your 10,000 mile service is due, but something peculiar comes with your alert. It’s a question: your car asks you if you wish to have the service taken care of within the next 10 days, or after.

You respond “in the next 10 days.”

Your car’s smart system contacts the car dealer’s smart system and arranges everything, but first…

Using Big Data to Sell to Individuals Instead of Stereotypes

One of the weaknesses of marketing has always been overgeneralization. Marketers have forever relied on grouping people into categories based on common characteristics, like age, gender, or household income, and then treating all of those people as the same — also known as stereotyping.

The problem is that no two people are actually the same, let alone a whole group of them.  However usually they’re similar enough that you can get away with grouping them…

ERP Tools, Enterprise Data Warehouse and Warranty Management

For many years, manufacturers have been trying to outperform the competition by offering up to five warranties on a car, for example, overusing the warranty argument in their marketing. Moreover, warranty costs have gone through the roof and repeated callbacks have ended up tarnishing the image of many companies. Therefore, it is obvious that their favorite integrated management software is not going to solve the problem, as it requires the integration of data from the entire company and all…

Insight into Forums – Using Big Data to engage customers, preserve your brand

When was the last time your car made a funny noise or ran a little hotter than usual? Chances are, you quickly consulted a web browser for answers and found your way to a forum full of similar consumers and car enthusiasts, all eager to get answers to questions and argue over best solutions. A few pages through the conversation and you probably end up with a fairly educated guess as to whether a trip to a mechanic, or a car parts dealer, is in order.

Forums like the one mentioned are…
