1) The mathematics would actually be correct. As oppossed to the NASA pukes who mixed British System Units with Metric Units and fried $millions of high-tech tax fodder in the Martian atmosphere.
You have not used Indian sofware. Furthe your example from Nasa was not the Sodtware programmers per se who programmed what they were given per the NASA rules. questioning the software requirements was something teh programming team did they were told to program it the way they were told. At least accordinbg to Computrer world at the time. Which if you do not want questions for your programmers go to India for your software
2) The online help and manuals would be written in literate English rather than in Yospeak.
You have not dealt with indian softweare manuals
3) They'd deliver the entire product rather than just delivering some of the product and a ReadMe telling you when the patch was due in.
You have never had to deal with delivery of product from India. there actually is a quality differnece and it is not in india's favor but they sell based upon the argument it is so much less expensive.
