The problem exists with other vendors also, and he is quick to point that out as well, in the beginning to the blog (if I can call the doc that). The problem lies a lot with the inefficiency of people working for such companies, but, on tracing back, it again goes back to the company and their ineffective policies, practices and methods. Taking an example, they give contract to a sub-dealer/contractor/associate who offers the best deal, in order to make more profit, who in turn compromises on quality to get his pound of flesh, which in other word means hiring of slip-shod salesmen/CC executives, who wants to meet his target with the limited capabilities and training etc given & so on the cycle continues.
