Next time when you come across those pesky intermittent bugs try adding them to a wall or a board instead of logging them in JIRA. The wall can be next to your standup wall or a separate wall. The key is to choose a space that will catch your teams attention.
This can help...
- notice a pattern with intermittent issues. You can then start grouping them under race conditions or corrupted data or specific state of the environment or performing tasks in a specific order, etc
- team is constantly aware of the random problems and so any related or similar issue found could help in investigating the root cause
- because the bugs are no longer hidden under a label in the bug database they have a higher probability of being fixed.
