Stories vs. Personas
Sarah Doodley (@sarahdoody.) explores the difference between user stories and personas. She correctly identifies the problem with personas is they can be poorly crafted and so become caricatures of themselves.
Atlanticbt.com where I am the Marketing Director uses Agile project development. Agile always starts with customer stories. Those stories provide the functional needs we program to in a series of "sprints". Sprints are usually one week long and represent a desire to get something in the customer's hands as quickly as possible.
Sarah's piece is an excellent summary of the importance of user stories, how to accurately collect and use them.
