Management
Keep in mind that every employee is unique and has his or her own set of unique skills which when shared with other employees can make them better at their jobs. So, come up with flexible workspaces that encourage team learning and try to encourage teamwork in your organization.
Cross-skilling staff maybe? Room for a switch in mental outlook? Less complex processes and systems that individuals will actually comply with? Better time management or better and more effective delegation (without the morale killing micro-management)?
These 3 strategies could change things in short order. Ask pertinant questions and you'll certainly gain the insights required for your business to move ahead once again.
