Agile Software Development Experiment
We’re considering trying an experiment in agile software development at Tyner Blain. There aren’t (m)any examples of agile software development that we can watch and study that include agile requirements development. Many people still think that agility and requirements management are mutually exclusive. If the responses to this post don’t […]

Is Agile Bad For Software Development?
Last week, Ivan Chalif, a product manager / blogger, tapped into a thread criticising product managers for not adopting and espousing agile, or at least rapid-release techniques.
