Customer needs
Which are the needs of our customers? Do we know them? Do we understand them?
From a market analyze, a PM can identify the customers needs regarding the current product and where there are the issues. A customer can complain about some parts of your service (product) and request patch for the missing part, but no customer can tell you which are the basically features that your product should include next year. This is our job! We must not only ask the clients what they want, we must to create needs,too.
I know than I’m not saying something new, but I believe that the video attached may summarize the development of a bad features for a product.
