The COI plans to 'substantially reduce' the number of agencies on the roster, which was established in 2005.
At the same time, it wants to place a greater emphasis on change management and culture change. The value of the framework is estimated at £2m per year.
Fiona Rogers, COI head of internal engagement and change, said the revised roster would reflect a move from 'classic internal comms', to strategic employee engagement and change, which is more typical to the private sector.
Rogers added: 'Central departments are having to deal with the changing nature of their relationship with agency bodies, which is becoming more strategic, plus an increasing emphasis on customer satisfaction.'
This emphasis reflects the need to deal with the ongoing redesign of government following the Gershon review of efficiency, the Lyons review which focused on the public sector in the regions, and the Transformational Government report.
There are currently 28 agencies on the existing framework, including 2Change, Bell Pottinger and Wolff Olins.
The new framework will also include 'lots' covering employee communication and engagement, brand and values, and evaluation.
The COI is seeking agencies with 'ability in and experience of successfully introducing change within established organisations, including the ability to coach and support leaders and managers'.
Elements of this include 'leadership communication' and 'developing and coaching manager skills'.
All suppliers interested in applying for the frameworks should go to www.coi. bravosolution.com and complete the pre-qualification questionnaire by 26 September.
