Is your agile project management tools serving you effectively

I am looking for better ways to organise and manage agile projects using more sophisticated tools, and would like to know your experiences.

Essentially I am looking for tools that can be implemented and running within 3-5 days, can be installed in house, satisfies senior management reporting, and which is extremely intuitive so the team actually wants to adopt it themselves.

Do you have tools that support your creativity, or do you think better tools are required to further reduce administration overhead?
