This book discusses traceability in software projects in general and contains an in depth investigation of how and to what degree traceability can be achieved in agile, state-of-the-art methodologies used for software development projects. Traditional traceability approaches (within requirements alone and from requirements to implementation) are opposed to the proposed integrative, tool based traceability solutions suitable for distributed, agile development teams. In detail it highlights how Atlassian's tools, especially JIRA and Confluence, can be customized and enhanced to support modern software development companies of all sizes to establish traceability over the majority of artefacts spanning the complete software project lifecycle. Additionally it provides concrete suggestions to support especially smaller software producers in their endeavour to survive ever-growing time or cost pressure and additionally forearm them against increasing uncertainty concerning demanded functionality in today's software project business.
