The Linux Foundation Estimates the Total Costs of Collaborative Projects to $5 Billion

Thanks to the COCOMO method, they managed to estimate the total amount of effort that is required for backtracking the steps of collaborative development to around 41,192.25 person-years, which means that it would take about 30 years for a team of 1,356 developers to recreate the Linux Foundation’s Collaborative Projects code base. As such, this effort is estimated to more than $5 billion (???4.4 billion).
