• The engineers working on your cabinet don't have the right training.
• Engineers don't give a high priority to doing patching to a high standard.
• Lack of cable management bars.
• Too much crammed into the cabinet.
• Lack of availability of the right length patch cables.
• Over time especially when a series of office moves are done, the tendency is for redundant patching to build up in the cabinet, leading to excess cables and switches becoming saturated.
