Figure 10: Altran’s OTN framework cuts time-to-market in half

Time-to-market advantage using the Altran 
OTN framework
Figure 10 shows the dramatic difference in time-to-market for new OTN products between not using the 
Altran software framework and using it: a decline from 30 months to 15 months. If all other factors remained 
the same—such as time to select the right hardware, negotiating hardware issues, building familiarity with 
third-party hardware and drivers—the time difference could be even larger. The staffing requirements for the 
Altran solution are expected to be lower because of the amount of existing development and pre-integration 
experience. Therefore, the cost savings could be even higher.
