An international leader in the aerospace / defense industry. Project based on cartography for military usage. 

A vast variety of applications: mission preparation, mission operation, with little reuse from project to project. A strong need to slash down NRC (Non-Recurring Costs) in order to remain in the market.

The question asked to CESAMES: Assess the technical & business feasibility of a software flexible architecture on the defined scope. 


Here are the 4 main phases that we followed:


Identification of a 150% Product Breakdown structure (S/W and H/W), and reuse maximization


Identification of standard S/W factory and project organization, 


Standardization & modularization of architecture: standardized interfaces, wrappers to avoid variability propagation through product line, 


Market segmentation & Business case to assess business relevancy.

150% Logical architecture


  • Strong increase of modules reuse:
Modules Variability Project example
w/o product line w/ product line
Standard 5% 57%
Variable(para-meterizable) 2% 34%
Specific 93% 9%
  • Strong reduction of NRC:
With 50% off-the-shelf modules With 100% off-the-shelf modules
NRC on a key project – 30% – 60%
  • Reduction from 3 weeks to 2 days of demonstration lead time.
