Over the years we have tried lots of different scoping methodologies. Ultimately we came to the conclusion that getting users involved early and often was the best approach where possible, so we came up with a modified agile methodology for our development.
As for user experience, we have used lo-fi prototyping as a great way to ensure usability and intuitive design for many years now. In Lo-fi prototyping the proposed system's user interface is made from paper and tested with real users (with no actual computers or technology) to achieve the goal the system is designed to achieve. This allows observation and understanding about what the user expects without anyone getting distracted by colours or the technology itself. For a short intro, check out http://www.slideshare.net/InteractionDesign/lo-fi-prototyping.
For the Intuto product we wanted to make sure we scoped it effectively, ensuring we could achieve our goal of a simple, fun tool for anyone who wants to put knowledge online. We had lots of great ideas for features, we had a good team with plenty of experience in online training and we had the technical know how, but how did we make sure we built the best possible system?
After extensive reading, we ended up taking the design sprint idea from Google Ventures and modifying it to fit the scope of a whole system. As expected this took longer than a design sprint for a single feature, but after a few days we managed to get walls covered with ideas (some great, some good, and some bad). From there we were able to identify the parts we knew would make Intuto simple and fun for our users.
Thanks to the hard work of our lead developer, within two weeks of the design sprint we had a working prototype that proved the most important (and clever) parts of the system would work, and work well! (more on the prototype in my next post).
Next we handed the desired feature list and the room full of ideas to the development team. They spent another couple of weeks ironing out each feature in detail, including lo-fi versions of all screens...Intuto was slowly coming together.
