Effect of Project Size on Errors

Both quantity and type of errors are affected by project size. You might not think that error type would be affected, but as project size increases, a larger percentage of errors can usually be attributed to mistakes in requirements and design, as shown in Figure 27-2.

As project size increases, errors usually come more from requirements and design. Sometimes they still come primarily from construction (Boehm 1981, Grady 1987, Jones 1998)
