The system provides fields "Blocked" and "Blocked reason" for backlog items and project teams use this functionality in order to track impediments. Typically, an impediment should be resolved within 1-2 days and project processes can be used to manage impediments, however, on large scale projects it is more difficult to manage this via process and there are some impediments which cannot be resolved quickly. Project teams need visibility of how long an item has been blocked in order to push for resolution within a stipulated timeframe. Project teams would like the ability to create views (grids filtered, summary widgets with drill-down/grid view capability, etc.) in order to see all blocked backlog items and for how long they have been blocked. Currently, you would have to dig into history for each item one-by-one in order to see when it was blocked.
We tried to create a UDF for "Blocked date" and to write business rules to autopopulate or make the field required when the "Blocked" field is changed to "Y", but there is no ability to write a rule based on the "Blocked" field.
