I've been asked to maintain a few of our software development tools; Clearcase (Views, Streams, Triggers), JIRA, Enterprise Architect and various document based repositories, Confluence, doku Wiki etc..
But as I wonder where does the line is when it comes to the "best practices" and cleanup efforts to make the most of these tools for development teams. for an SysAdmin perspective it's quite easy; Make sure u maintain the application, network and backup system. but when it's development support and in the term used "Tool's Smith" I believe is half way between a lead developer and system administrator.
