To ensure the quality of delivered products, each team follows a code review process differently. Some teams prefer to pair program, some create separate tasks to track formal code reviews, while some use tooling systems to achieve this result. Atlassian solution named Crucible (http://www.atlassian.com/software/crucible/overview) allows you to conduct peer code reviews much effectively. Jira/GreenHopper allows you to track and manage the process in a much easier way and integrates smoothly with your code repository.
Easy and flexible reporting and visual display of information, and focusing on only relevant information is the Agile way of doing it. Sufficient reporting capabilities of Jira/GreenHopper, easy integration with other Atlassian suites, and additional features of gadgets allow you to achieve the desired results quickly.
The notification capabilities of e-mail or SMS allow your teams to stay notified all the time. Subscriptions to saved filters provide routine notification of JQL queries and watching individual issues provide opt-in notifications upon changes. Additional hooks and plugins for notifications make it easy for both development and operations teams to be notified and relevant actions can be planned accordingly.
The easy integration of tooling systems such as Jira, Bamboo, and Crucible within the IDE can be achieved using IDE Connector (http://www.atlassian.com/software/ide-connectors/overview). It allows teams to focus on work and less on tooling. Teams can easily integrate these tools with the development environment and each team member stays connected and updated to the changes. This leads to an increase in productivity while minimizing the time spent on waiting significantly.
The vast list of additional available plugins for the tooling system allows you to choose and work with the ones suiting best to your team. To name a few, the plugins such as Tempo for timesheet, Issue hierarchy plugin and Charting plugins for reporting, and so on extend Jira/GreenHopper to provide needed features through a vast market place of third party providers.
