Too Long; Didn't Read
A Product Manager is responsible for the entire product life cycle starting from conceptualisation till launch. The real test of a true product manager begins post launch of the product. The journey to achieving the product success metrics is time taking, full of surprises, may be depressing but is worth taking for a product manager to bring out the true potential of his/her product. No product manager can predict the outcome of a product even in similar conditions unless it hits the launch road with the actual customer. A product manager must be a good listener first before being a good speaker.
