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:
1.
Identification of a 150% Product Breakdown structure (S/W and H/W), and reuse maximization,
3.
Identification of standard S/W factory and project organization,
2.
Standardization & modularization of architecture: standardized interfaces, wrappers to avoid variability propagation through product line,
4.
Market segmentation & Business case to assess business relevancy.

CREATED VALUE
- 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.
