4. Example – New Boeing 787 Software development of Boeing 777
1,280 onboard processors
500,000,000 $
Software Development for the Boeing 787
4,000,000,000 $
Boeing cannot this quantity of software in-house within a reasonable time frame : supply chain similat to the Japanese firm
Many critical subsystems requiring defect free, on time within budget software components
Similar to the Japanes company, Boeing or their main suppliers have to use VSEs
Example: sièges des 787
Lifecycle of plane is about years !

5. Exercise
Using the Reifer productivity tables, estimate the number of person-years required to develop the 787 software.

6. Exercise - Answer $4 Billion for software development
Number of lines of code (for the airborne domain) = $4 billion/$200 per line = 20,000,000 lines of code
Number of staff-months = 20,000,000 lines/100 lines per staff-month = 200,000 staff-months
Number of staff-years (based on 10 months of work per year) = 200,000/10 = 20,000 staff-years
