Grey problem (gray problem) is a term for an IT 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 (see Figure 1). The problems in each quadrant have certain characteristics: Q1 - 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. Q2 - 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. Q3 - Every so often a one-off problem occurs, and the cause of these may never be found. Q4 – The technical ownership of these issues is unclear and so they are referred to as “grey problems” i.e. not black and white. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Grey problem」の詳細全文を読む スポンサード リンク
