There are plenty of good tools on the market, so who needs GRADE?
Most of the good tools have been conceived by software people for developing software in the fastest most efficient manner, leaving it up to the imagination of the software designer what the software should do. By contrast, GRADE lets you create models that depict all relevant aspects of a sociotechnological system, including the people factor. That way, you can design software that supports the user better in performing his work.
