I'm a project leader in a development team for a UK local authority. As part of this role I have an account management responsibility for several departments in the authority and need to maintain a lists of contacts, projects, development team members and tasks.
I've been able to use Cayra to build a relationship map of all of these so that I can focus on specific areas, such as projects, or my tasks, or my clients, or any of my current project teams (amongst other possiblities) - it has made it much simpler to see the work I'm responsible for
See the attached screenshot for an example of how I'm tying things together - it's made a complex set of relationships very easy to manage!
