That's what seems so very puzzling in these stories. These shortcomings in the delivered software appear more like insufficiently tested requirements (of course, the execution could be the sole reason too).

I'm not sure if contractors are needed in order to test the requirements against the actual use-cases _before_ even initiating a bidding process for developing any systems/software.

After all the force probably wants to describe what's needed. Someone has to make sure the desired new capabilities align with actual existing and desired workflows.

Perhaps, in this navsystem case, the ability to efficiently analyse/visualise the region's depth profile could have been stated in concrete use-case form, including the response times, scaling etc. This would then become the basis to test at the acceptance stage.
