Grey Problem
In IT, a grey problem (or, gray problem) is a problem where the causing technology is unknown or unconfirmed.
Common grey problems are:
- Intermittent errors;
- Intermittent incorrect output, or;
- Transient performance problems.
Because the causing technology is not clear, IT departments often find it difficult to allocate the problem to a Technical Support Team (platform team).
Background
Combining frequency and causing technology information can provide a view of the complexity of a problem and so indicate how difficult it will be to investigate.
The problems in each quadrant have certain characteristics:
Quadrant 1
In a typical IT department 80 to 90% of problems are solid faults that are easily tracked down to a causing technology. The appropriate technical or platform support team efficiently deals with these problems every day.
Quadrant 2
Some recurring problems are due to a Known Error, or are obviously being caused by a particular hardware or software component. These problems are handled by technical support people working with suppliers.
Quadrant 3
Every so often a one-off problem occurs, and the cause of these may never be found.
Quadrant 4
The technical ownership of these issues is unclear and so they are referred to as “grey problems” i.e. not black and white.
Impact
Grey problems have a significant impact on IT service, and:
- Form the bulk of ongoing recurring problems
- Create a disproportionately high IT support workload
- Give a pointer to more serious problems to come
- Cause the business to adjust practices around the problem
