In this day and age when knowledge workers are entering and exiting organizations practically on a daily basis, many organizations struggle with how best to arm their workforce with the knowledge they need to maximize their performance thereby increasing the organizations efficiency and effectiveness. This study investigated whether or not emerging social media tools like microblogs can be used by organizations to foster informal learning, provide performance support and ultimately improve performance through the creation and utilization of communities of practice. The hypothesis was that when participants used the tool to: 1. Post questions, 2. Answer Yammer’s question: “What are you working on?” they would reveal information that would inspire colleagues, in their Yammer community, to reach out and offer performance assistance. This would result in colleagues learning from each other and assisting each other and would eventually turn these groups into Communities of Practice.

Findings indicated that:

  1. Participants used the tool to post many different types of information, not just questions, and work activity updates;
  2. Participants did not generally reach out because of work activity updates but they did reach out to respond to questions;
  3. Participants perceived that their learning, effectiveness and efficiency were increased because of their Yammer use;
  4. Participants received assistance on the job through many different types of information that they post, not just questions and work activity updates;
  5. Participants felt supported by the Yammer community.
