Improving Integrated Processes

I'm currently working with a client to prepare for a KM software migration to new servers. The platform is SharePoint and the migration will be the easy part. The hard work is the upfront decisions that need to be made to implement new business rules for future content mgt, knowledge and information sharing. The client has 4 web portal applications at their disposal and my goal is to assist them in framing an effective utilization strategy keeping both internal and external stakeholders in mind as they grapple with optimal solutions for the organization. A huge challenge but the client is committed to improvements,which is always a good thing!
