Communities in a work setting—also known as communities of practice—are groups of people coming together as a consequence of work or occupation-related responsibilities. This chapter explores how these groups allow practitioners or knowledge workers to share stories of their experiences and compare notes on topics such as procedures, vendors, and teamwork. Engaged communities encompass a range of activities including regular meetings or conference calls, storytelling, speaker series, participating in intranet or online discussion groups, information sharing and content curation, sharing calendars of events and key dates, polls and surveys, review of resources and software, thought leadership, professional development and business development. The chapters shows how benefits of communities can be augmented through improved engagement of community members, community management and administration, and implementation of a subject taxonomy.
