Many Eyes d’IBM, le web 2.0 et la représentation visuelle des connaissances:

Posted on July 26, 2007. Filed under: Francais, Outils |

Les 2 nouvelles dimensions portées par le web 2.0 à savoir les dimensions visuelles et sociales, sont à l'honneur dans l'application du Watson Research Center d'IBM :

Démocratriser la visualisation des connaissances IBM nous dit oeuvrer pour la démocratisation de la visualisation des connaissances. Qu'on se le dise ! Et que l'on en tire les conclusions requises ! La fructification et la valorisation des connaissances sont bien au coeur des enjeux économiques actuels.


Many eyes offre la possibilité, à partir de données et informations:

  1. De choisir son modèle de représentation ( carte, graphique, diagramme en réseau, treemap, tag cload, etc.),
  2. De réaliser son schéma,
  3. De partager sa réalisation et/ou de commenter celles d'autrui.

Tout ce que l'on attend depuis de nombreuses années du logiciel Power Point de Microsoft, dont la pauvreté des modèles de visualisation n'a cessé d'en désespérer plus d'un. Voir à ce sujet le post d'Amaury. A retenir de Many Eyes: Les objectifs et les avantages de chaque type de représentation. De quoi opter pour le modèle susceptible de communiquer au mieux les données ou informations que l'on veut communiquer

Visual tools for the knowledge worker : PowerPoint and MindMap

Posted on July 17, 2007. Filed under: English, MindMap, Outils, PowerPoint, rules |

As industries get more and more productive (as measured by the increase of EBITDA/employee), we see the emergence of the knowledge worker (see Peter Drucker 1959's paper). This emergence can be measured by the growing importance of tacit interactions between workers, and as a result more and more intellectual capital (employee knowledge and abilities, in the form of information) is exchanged in a non-structured way. Tools like email, instant messenging, collaborative workspaces, allow synchronous and asynchronous exchanges of information and knowledge over a wide area (across different sites and organizational departments). But when the stakes get higher such tools are not enough. This takes place in several cases :

  • the information is complex and need to be synthesized / clarified
  • the targets (individuals, departments or businesss units) lack a common culture and do not share a common vocabulary
  • the communication is massive and/or urgent and/or critical
  • a common future vision (a new organization, market, product) existing as concept must be formalized, shared and people adhere to it

In such cases visualization has proven to be a useful approach, and the most widely used tool by managers is PowerPoint, but more recently another one has started to get traction : MindMap, named after Tony Buzan's early 90's work

Both tools have got their fans and their detractors, so let's look at the opposing parties arguments :

  1. PowerPoint
  • Detractors : the most famous vocal critic is certainly Edward Tufte, a recognized guru in information visualization, and his "PowerPoint is Evil" phrase is widely quoted. His thinking is developed in his book "The Cognitive Style of PowerPoint" and mainly states that the tool is misused, that information is buried in tons of slides, that the bullet point approach is terrible, … Other critics include the French entrepreneur Rafi Haladjian in his famous 2004 essay "Become beautiful rich and intelligent with PowerPoint", full of irony.
  • Pros : Donald Norman, a famous designer who has been the head of Apple Advanced Technology Group, teaches at various universities and co-founded the Nielsen Norman Group, has a strong stance against him (see Cliff Atkinson's interview and D. Norman's own defense piece). Another strong user is entrepreneur turned VC Guy Kawasaki with his 10/20/30 rule for PowerPoint
  • Tools & resources : for software there is Microsoft PowerPoint of course, but also Apple's KeyNote, Google's recent acquisition of Tonic, a web-based presentation tool, and open source Impress from the OpenOffice suite. For good references and tips in addition to the ones listed above, see Cliff Atkinson's book "Beyond Bullet Points" and more on my Delicious bookmarks, updated regularly
  1. MindMap
  • Detractors : some recent research limit its scope and power, such as a 1998 study on college students and metacognition that indicates focusing too much attention to the tool limits content learning
  • Pros : of course Tony Buzan's, a British psychologist who started working in the 70's on cognitive abilities such as creativity and memorisation and is often referred to the "inventor" of mind maps (see his 1991 book "Use both sides of your brain:New Mind-Mapping Techniques") but also in France the French Heuristic School (see the scholl website and the Petillant portal, a key node of the mind mapping community in France)
  • Tools & resources : commercial softwares include the very good MindManager from Mindjet or Inspiration (more for the teaching/education environment), open source FreeMind and web-based Reference books and websites include the good portal, the book " " and my Delicious bookmarks, plus the following video from Tony Buzan "himself"

This post has only been a brief introduction to those tools … more in a future one !
