Tracker is a project management tool developed for managing Agile projects. It consists of four main modules: Planning, User Stories, Statistics and Billing. The user stories is the basis of the planning. There is a possibility to arrange the stories by weeks. Programmer can plan his work and break it up into tasks. The time used for working on the story is recorded and associated with the specific tasks. The system automatically counts the total time spent on the User Stories. The records that the programmer made could be seen by both, the client and the project manager at the statistics page.The user stories are a virtual version of the post-it notes, used for making notes of the plans for the day and attaching them to a monitor or planning board. In Tracker it looks like cards of different colour. By clicking on them, you can see the list of planned, processed and completed tasks and actually the results of work. The color of cards corresponds to the status of the story: gray for estimated, blue for in process, light green for completed and green for accepted.There is also a history of versions in Tracker that contains all updates from the creation of a story to its acceptance, as well as the records on who, how and when changed it. The last module is Billing, where the client can see invoices, issued based on the actual time worked by the developers. Tracker is integrated with bookkeeping and various systems involved in the payment processing. It allows to review the history of all transactions, such as payment through the Elance system or bank transfers. The user came, saw and paid there is no other way to describe this section.
