The ICT-KM Program's 2004 Investment Plan was designed to address major needs within the 15 CGIAR Centers. Various activities under this plan have given staff access to System-wide resources and a unique set of collaboration tools; provided seamless communication across the Centers; promoted greater knowledge sharing in support of increased effectiveness; enhanced the communication capabilities of scientists through advanced research networks; and provided remote offices with the basic Internet connections that many of us take for granted. Much has been achieved over the past two years; much has been learned. The 2006 Investment Plan, which covers Phase II of the Program, focuses on providing follow-on support for several critical, System-wide activities that were started under the 2004 Investment Plan. Only by consolidating the gains of these activities can all CGIAR staff and partners benefit from their potential returns. Efforts have also been initiated to ensure that the necessary human resources are in place to enable the Program to effectively fulfill its objectives and plan for future investments. The main scope of the 2006 Investment Plan is centered on two relatively large projects: CGXchange and Improving CGIAR Effectiveness through Knowledge Sharing (KS).
