Feature requests are one of the most important challenges a product manager has to deal with, in particular for web based products. It has a great influence on product value and could potentiality steer the product away from its set vision and strategy.
Deciding whither or not a product feature is worth development might seem like an easy straight forward task, all you have to do is get feedback on most demanded features from your users and start evaluation to prioritizing development. For products that have clear narrow goals with limited set of features and use cases this is the right way to go (for example a CRM software or a mobile app). While for complex web products that incorporate large set of interactive services and features (online networks, Saas, community hubs, social media …etc.) this light weight approach has a high potential of failure. Complex metrics accompanying complex products makes feature analyzing and evaluation a hard and lengthy process.
