The ability for my staff to easily track their time in their own personal calendars, keeping them accountable for all of their work hours. I also love that it can be used as an internal tool between employees within our organization so that they are able to keep up-to-date about upcoming projects or events. It would have been nice if there was more integration into other Atlantas systems like Salesforce, but this hasn't been an issue yet. We've had no issues using Atlantis since we started using it last year. Overall it has helped us improve efficiency by having one place where we can see what tasks need doing next. I like how easy it was to set up, and use. It makes keeping track of our dogs much easier than paper files and also saves me time. I dislike that sometimes it has trouble connecting to the internet. Also, I don't like that some features are not available on all versions. We used Atlantis for tracking our animals. It's made it much easier to keep track of them. It also helps us save money because we no longer have to pay for paper records.
