Goals for SEAM

•  To be a collaborative tool for developing shared understanding between all business and IT actors.

•  Similar to « mind maps » but with more structure to guide the thinking process

SEAM Ontology

•  Concrete (project-based, story-telling, “examples”, …)

•  Rigorous (discrete simulation, system dynamics, logic)

•  Subject-based (viewpoints, goals)

Les idées reçues

•  Les silos sont mauvais •  Il faut les abolir

Abolir les silos ?

•  “Process-centered improvement techniques saved companies by destroying them.”

Les silos sont indispensables

•  Chaque silo maintient d’abord sa propre survie et ensuite celle de l’entreprise

•  Un silo peut être vu comme un système homéostatique qui maintient un ensemble d’états stables (normes) sur lesquels d’autres silo peuvent s’appuyer.

•  Certaines de ces normes nous arrangent et certaines autres pas.

Notre point de vue

•  Les silos sont indispensables au bon fonctionnement de l’entreprise

•  Les abolir n’est ni possible ni souhaitable •  Si l’entreprise survit, les silos

communiquent déjà, peut-être pas autant que l’on voudrait

•  Créer et maintenir le bon niveau d’échanges entre silos est un défi

Notre recommandation

•  Identifiez les points d’entrée possible •  Allez sur le terrain •  Le BA permet de créer des plus grands silos •  Le BA contribue à “donner” ce silo au

métier
