• It should be correct i.e. efficiency should be as per the specifications
• It should be reliable; it should mathematical function accurately for a long-lasting extent of example and too manoeuvre right finished all ranges and accumulation of information.
• It should be robust; detrimental inputs or data should be known and seemly nonachievement phone call should be flashedability. It should never contact.
