Everybody is trying to do Agile development, some do it right, others end up using a hybrid solution. The "Ad Hoc" What's Hot" Methodology is for shops that are transitioning to Agile Development but since they are having trouble transitioning into the short cycles, they can run larger projects as per normal but run smaller "Ad Hoc" projects along side that have definite features that will be released in a 2-4 week cycle. These project are done to ensure they are keeping up with what is hot.
For example, you have a legacy web application but iPad is hot so you create an "Ad Hoc" project to develop an app for the iPad. It has specific features and its unit tested throughout the process.
If you would like more information on this new methodology please email Susan Fischer at email@example.com and we can send you a white paper.
A friend of mine twittered this earlier today and I found it interesting so I thought I would pass on the link. The article compares Journalism concepts to those developers use in developing and debugging code. Its an interesting article that is both enlightening for journalists and developers.
