Qualité des produits : une introduction

La qualité est de plus en plus une variable essentielle pour toute entreprise (les universités et écoles même publique sont des entreprises) qui propose des biens et/ou des services sur un marché. La qualité d'un produit couvre sa performance, mais aussi sa disponibilité. Elle est devenue un argument essentiel pour les entreprises parce que critère essentiel de choix pour les clients. C'est un facteur que les premiers doivent savoir atteindre de sorte à éviter que les seconds ne puissent la mettre en doute.
Une définition de la qualité Bien souvent, le terme « qualité » est interprété de manières très diverses. Dans le langage courant, on parle de produit de première qualité, ce qui signifie que le client est satisfait de la marchandise et des services offerts. Pour lui, la qualité est synonyme de satisfaction. Pour l'entreprise en revanche, la qualité implique par exemple la fourniture d’un service à des coûts avantageux.

The Science Author Clive Thompson Does Not Think Tech Is Ruining Your Mind

The New York Times (09/24/13) Nick Bilton

In an interview, technology writer Clive Thompson explains why he believes technology is improving human intelligence. "There is something about the ability to externalize our thoughts and compare them with other people in a public way that is really transformative for the average person," Thompson says. He also believes that computers are augmenting rather than supplanting the human memory, which has always relied on outside sources, such as written notes, books, and other people. Thompson says people are "social rememberers [who use] our co-workers, our partners, and our friends to help us retrieve the details about things that they are better at remembering than we are." In addition, he says the Internet gives users an "ambient awareness" of current issues and other people's lives as they follow small posts over a long period of time. Thompson says computers also provide a resource for what he calls the &quo…

How Google Converted Language Translation Into a Problem of Vector Space Mathematics

Technology Review (09/25/13)

Google researchers have developed a technique that uses vector space mathematics for language conversion. Instead of using versions of the same document in different languages, the technique relies on data mining to model the structure of a single language and then compares this to another language's structure. Their method is based on the notion that all languages have to describe a similar set of ideas, requiring similar words to accomplish this. The researchers determined a way to represent a language using the relationship between its words. The set of all the relationships, or the language space, can be visualized as a set of vectors pointing from one word to another; linguists recently have found that these vectors can be approached mathematically. Converting one language into another becomes a mathematical task of determining the transformation that converts one vector space into the other. To map the vector spaces, the researchers use a small bi…
