Many (many!) software and Web projects fail due to poor conception and planning. We'll examine different approaches to mapping out what you want to build, whether you plan ahead or roll it as you go. We will look at the common documentation types such as wireframes, use cases and clickable mockups; good tools for collaboration (wikis, bugtrackers, project management tools); and best practices for gathering feedback.
