Matrix structures can be expansive in their designs. Most of these elaborate designs have a focus point of interest such as high crime rates in their particular surrounding area. Others high reasons might be sexually transmitted diseases, juveniles, and unemployment. These areas might use patrol divisions, gang units, narcotics units, social workers, probation and parole, public health and safety officials, and school officials for juveniles. The goal is to attack a primary reason but serve to help reduce other crime involved. Governmental agencies represent over 60 percent of the matrix structures used in the law enforcement community. Problem-solving partnerships are key in making the system work properly and effectively. Constructing matrix types of units and organizations allows the police department to be flexible (Gaines, L.K. and Worrell, J.L., 2012). Allowing Police departments to gather a mixture of resources exhibits better problem-solving skills. The pitch can be made that by restricting a particular agency or unit to gather information could be detrimental in the alternative solutions that could have be drawn. The biggest problem with a matrix structure is that they are very hard to coordinate properly with the large number of units and divisions contributing.
