Spectrum provides three basic services to the federal government; these services involve detention, transportation and security services relating to federal prisoner/detainees. Although Spectrum focuses upon these three divisions of services, the company has provided a variety of other services in the past and is becoming increasingly capable of providing such services. Although Spectrum's origin involved a focus upon security services, the company rapidly diversified into transportation and detention services. Spectrum's heavy involvement in detention services is of especial importance. Spectrum's strong and steady growth has allowed the company to achieve various economies of scale as well as the efficiencies which result from diversification and specialization. With respect to these last two aspects, Spectrum now has an officer corp comprised of over two hundred officers of differing skill levels and training who can be dispatched to a particular project depending upon its unique requirements.
