The social system is the source of the people and mechanisms that provide technical support to those in the target population who are ready to adopt the improvements. Basic technical information about how to make the improvements can be packaged in various forms such as manuals, websites, audiovisual presentations, etc. These communication tools can serve as excellent resources for adopters by providing initial guidance on how to get started, detailed instructions about implementing specific improvements, and other pertinent information that is relatively straightforward and easy to explain.

However, adopters often need a deeper level of support and information that is best communicated through interaction with colleagues. Avorn (1983) discusses the benefits of person-to-person contact in educational outreach. Szulanski (2002) suggests visits to a high-performing site to aid in replication of "better ideas" or best practices. Those individuals from the successful sites with personal experience implementing the improvements are often the most effective providers of technical information.
