I work as a business analyst and I currently oversee much of the development efforts of an internal project. I'm responsible for the requirements, specs, and overall testing. I work closely with the developers (onshore and offshore).
The offshore team produces all of the reports. Version 1.0 had a 9 month development cycle and I had about 4-5 months to test all the reports. There was the usual back and forth to get the implementation right.
Version 2.0 had a much shorter development cycle (3 months). I received the first version of the reports about 3 weeks ago and noticed a lot of things wrong with it. Many of the requirements were wrong and the performance of the queries was horrendous at 5x - 6x longer than it should have been.
The onshore lead developer was out and did not supervise the offshore development team in generating the reports.
Management knew about the performance issues and I also told them I was trying to find a way to improve performance; they did not explicitly approve of sending test queries, but they were also not concerned with the fact I was doing that. I took a look at the SQL in the reports and was able to improve performance greatly (by a factor of 6x) which is acceptable for this version.
I sent the updated queries as guidelines to the offshore team and told them they should look at doing X instead of Y to improve performance and also to fix some specific logic issues.
I then spoke to my managers about this because it doesn't feel right that I was developing SQL queries, but given our time crunch I saw no other way. We were able to fix the issue quite fast which I'm happy with.
Current situation: the onshore managers aren't too pleased that the offshore team did not code for performance. I know there are some things I could have done better throughout this process and I do not in any way consider myself a programmer.
My question is, if an offshore team that works apart from the onshore project resources fails to deliver an acceptable release, is it appropriate to clean up their work to meet a deadline? What kind of problems could this create in the future?
Update: So far management is upset with the offshore team, but have not "reprimanded" me in any way, so I'm not sure in their eyes if what I did was wrong, but I think their main source of frustration was the offshore team was not able to come up with a solution and I was, especially since this sort of performance issue had come up in the past. I am not defending my actions, but I want to give context so that the picture is a little clearer. I accepted the answer that most criticizes my actions I agree it's not something that should be done by someone in my position.
