I am working as a Jira administrator for a development chapter, that is associated to a specific business unit. Currently we have the problem, that employees are creating not only bug tickets (this is highly recommended) but also tasks and story type issues, when they want to apply new product requirements. As a result our backlog is flooded with lots of old tickets that represent requirements that are more than one year old. Our backlog has become a repository of ideas for new features that should not be forgotten. As a result we are working now with different product requirement pages in confluence and we generate new Jira tickets by marking the headlines of potential userstories in the confluence pages. I would like to have an opportunity to allow the users of the development chapter to create stories and bug tickets and to permit the members of the business unit only to create bug tickets. AFAIK this is not possible by setting up the permission schemes in Jira. Are there other ideas?
