Approval Processes - The good, the bad and the downright ugly

I work at the RSPCA as a Senior Marketing Executive and one of the biggest issues in the society is our current approval process. So, I'm on a mission to discover new, efficient and exciting ways of getting campaigns around to stakeholders in a timely manner for feedback and approval. I'm interested to find out how others manage their projects in a way that works for everyone. What, if any, software packages do you use to help you on your way? What issues and barriers do you come up against? What, in your experience, works the best? Please let me know anything you think may be useful.

Drop me an email at belle.price@rspca.org.uk if you're willing to help me on my mission!

Thank you in advance.
