Jira Portfolio version supports using Initiatives and are widely used at our company. Aha! provides the perfect place for reporting and managing Initiatives (using Master Features or Initiatives in Aha!), but very difficult without the integration. Aha! needs to keep up with the Jira structure so businesses can use the tool effectively
Not sure about Master Features here, but I would hope that Initiatives in Aha! could be mapped to Initiatives in Jira.
