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:

Finding:


• The embodiment of the concept and

the allocation of physical/informational

function to elements of form, and

definition of interfaces among the

elements and with the surrounding

context

WHAT IS AN ARCHITECTURE? (FROM CRAWLEY)

What the system DOES What the system IS

KIND REMINDER ABOUT AN ARCHITECTURE AND CONFIGURATION


• The embodiment of the concept and

the allocation of physical/informational

function to elements of form, and

definition of interfaces among the

elements and with the surrounding

context

WHAT IS AN ARCHITECTURE? (FROM CRAWLEY)

WE NEED FIRST TO ANSWER:

« WHY DO WE WANT TO VALIDATE AN ARCHITECTURE? »

IS IT TO MAKE SURE ARCHITECTURE WILL ANSWER THE TENDER?



« ANSWERING TO TENDER »: AN INDUSTRIAL FEEDBACK…

« We are losing calls for tender… and we remark

that our competitors won by not reaching to the

tender’s expectations »

The truth:

OR IS IT FOR SMARTER THINGS?

• 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?

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.
