How to Gather Support for a Project
To gather support for a project, create and communicate a vision that demonstrates real value to the organization as a whole. Attempt to let others share in your vision creation. This gives them a reason to support you and gives you the benefit of their ideas. Individually recruit key supporters for your project. Wherever possible, show, don't tell. If possible, construct a prototype or a mock-up to demonstrate your ideas. A prototype is always powerful but in software it is far superior to any written description.
