As a product Manager, my most innovative practices are as follows
1) Every feature should have unique Benefit for the user
2) Interface should be User friendly ( User Interface if it is a technology product or Ambiance if it is a restaurant Or packaging if it is a retail product)
3) last but not the least Product should be Fun to work on ( Does not mean you have to include cartoons but navigation should be quite easy for technological products, Pathways should be lightened or filled with music for a super market or Opening a package box should give the customer a surprise for a retail commodity product)
