  1. TCS Software Design Review

  2. Have we understood all the requirements? • Do we understand all the quirks of the hardware? • Is the design capable of doing the job? • Can it be completed with the available resources? • Can it be commissioned in an acceptable time? • Can this system be supported & maintained?
