Calculate the productivity, SLOC per work month, of each of the projects in the following table, and also for the organization as a whole. If the project leaders for projects "a" and "d" had correctly estimated the source number of lines of code (SLOC) and then used the average productivity of the organization to calculate the effort needed to complete the project, how far out would their estimate have been from the actual effort?
