To arrive at that figure, the Foundation analyzed the code repositories of each one of its projects using the Constructive Cost Model (COCOMO) to estimate the total effort required to create these projects. With 115,013,302 total lines of source code, LF estimated the total amount of effort required to retrace the steps of collaborative development to be 41,192.25 person-years — or 1,356 developers 30 years to recreate the code base present in The Linux Foundation's current collaborative projects listed above.
