The challenge that lies with EMC management at this point is how to seamlessly integrate offerings from all its prior acquisitions within the 'federation'. The company has maintained its intention to continue with the federation model despite pressure from activist investors to completely spin off growing businesses. EMC has showed capability in managing its businesses, as evidenced by its decision to keep VMware as a separate entity and spinning out Pivotal to encourage growth and innovation. On the other hand, most other companies that EMC has acquired now either stand as different divisions within EMC (content management or information security) or form the part of EMC's core information storage segment.
