WITHIN THIS CONTEXT: SYSTEM ENGINEERING IS CHANGING
Architecting is the new « trend » to
reach performance next level for
product & service:
It is, now, the key element for
platforming activities, as well as
product line and road map
questions
Architecture choice is the most strategic
decision that engineering team have to take
Thus it’s clear that:

• To assess the capability to adapt a given architecture to variety of need?
• Notion of modularity
• Notions of adaptability to configuration
• To study where are « margins »
• Engineering Overquality
• Available performance for next generation of product
• To understand the potential impact of uncertainty into the design?
• To assess the « cost » of requirements (from a strategic perpective)?
• To find the « right » platform?
• To give design guideline to design team?

System A System B System C
Performance
criteria
NON-STRUCTURING UNCERTAINTY: will note change
the fact that System A is less performant than both System
B and System C.
STRUCTURING UNCERTAINTIES : as it is, these
two uncertainties do not allow you to say without
hesitation which system is the winner. Doing so
requires to try and reduce uncertainties to a point
where you can conclude which system is the best
one regarding this performance criteria.
