Issue tracking systems and methods for a configurable project hierarchy

A computer-implemented method for managing a configurable project hierarchy using an issue tracking system, the method comprising:

• receiving a first request to add a new hierarchy level for a project managed by the issue tracking system, the project managed by the issue tracking system having a plurality of issue items, each issue item of the plurality of issue items having a set of fields including an issue type field, issue items in a respective common hierarchical level having a common issue type value in a respective issue type field, the first request received from a client device operating a client instance of the issue tracking system;
• in response to receiving the first request to add the new hierarchy level, identifying an existing project hierarchy for the project in a data store of the issue tracking system;
• generating a modified project hierarchy by adding a new hierarchy level identifier to the existing project hierarchy;
• in response to the new hierarchy level being added above a particular level of the existing project hierarchy, assigning the particular level as a child to the new hierarchy level;
• in response to the new hierarchy level being added below the particular level of the existing project hierarchy, assigning the particular level as a parent to the new hierarchy level;
• receiving a second request to associate a particular issue type with the new hierarchy level, the particular issue type corresponding to a particular issue value stored in the issue type field;
• in response to receiving a second request to associate a particular issue type with the new hierarchy level, associating the particular issue type with the new hierarchy level by storing a new association data record in the data store of the issue tracking system;
• and
• in accordance with a particular issue item of the plurality of issue items corresponding to the particular issue value in the issue type field, assigning the particular issue item to the new hierarchy level.
