Hi Naveen - welcome to myASQ & thank you for being a member!
it seems that many of your issues are the same as we all face.
1. lack of training
2. Lack of communication
3. You get what you pay for - low prices don't always mean good quality
4. Teamwork gaps
5. Lack of complete planning - silos in work department
Looks like your solutions would help in many areas.
Good Luck!
Trish
