Volvo Group General EA Principles
•  1 Conformity to standards (Standards for all parts in EA pyramid)
–  Drive usage of open and industry standards at Volvo
•  2 Autonomous & loose coupling between components & applications
–  Flexible subsystem and granular component setup, avoiding monoliths
•  3 Simplicity in solutions and work methods
–  Clean solutions from technical, application and user perspective. Strive for simplicity in
project management and system development methods (ISGDP, Agile …)
•  4 Strive for usage of existing Volvo services
–  Whenever possible avoid application specific infrastructure, instead utilizing already
existing services at Volvo (Databases, App servers, Brokers, Data Warehouse,
Process perf..)
•  5 Robust solutions = asynchronous, caching …..
–  Active coaching of projects to achieve robust solutions securing uptime e.g right logic in
right application tier, usage of good application architecture including integration
solutions e.g avoiding synchronous dependencies

promoting test driven development, focus on database tuning early on, non-talkative
messaging between UI and server etc.
•  7 Secure solutions
–  Active coaching of projects to achieve secure solutions from the start. Correct
functionality and data accessible to the right users … includes usage of Volvo decided
infrastructure …
•  8 Good Integration solutions
