Content

Introduction - Overview Coordination of virtual teams :

– explicit interaction model– explicit interactions vs. implicit interactions

Methods and algorithms to support cooperation groups :– logical organization, – network architecture

Objectif

Cooperation : a new research theme ? Dimensions of Cooperation Cooperation vs. Distribution Cooperation : problems and issues (not

exhaustive) Overview : coordinating a virtual team Deepening

Cooperation (definition)

working together in a common objective win/win

Cooperation dimensions (1)

Distribution– in space– in time– … in organization

Collaboration

Taxonomie - 3 C

Communication : échange simple d ’informations,

concernant par exemple ce qui est à réaliser

et l’état d ’avancement du travail

Coordination : règles et procédures

qui assurent le fonctionnement d ’un groupe

(gestion de flux de tâches)

Collaboration : création d’une vision commune

des questions à traiter et d’un espace commun

pour stocker et partager les informations

Cooperation vs. Distribution

Human centered distributed system– distribution transparency is not always

requested– especially, concurrency transparency is

antagonistic with cooperation

Problems

Human factor Communication Coordination Collaboration Autonomy and privacy Mobility Integration of dimensions

Issues (1)

Model of user– usage analysis– multiple interfaces

Issues (2)

Model of explicit interactions– coordination model and language– flexibility of control flow– flexibility of data flow

Issues (3)

Model of implicit interactions– awareness model and language– awareness technology– awareness visualization

Issues (4)

Relationships between different dimensions of cooperation– relationships between explicit/implicit

interaction models– Switch from asynchronous to synchronous

work (respectively)

Issues (5)

Networking protocols– group management – ...

Overview

Coordinating a virtual team

Deepening

Advanced transaction model to allow more flexibility of data flow.

Cooperative workflow: flexibility of control flow and data flow

Switch from asynchronous to synchronous work
