The conference paper presented an aspect of how social network could be organised and formed to support knowledge sharing within group of professionals. What I realized in my research, informal sharing or learning is important for organisations. Nevertheless, it can be an impact for organisations. Appropriate planning is the benefit of organisations' profit making. One of advantage of Communities of Practice (CoP) is enabled the development and dissemination of knowledge. It is because professionals can share their particular knowledge. The knowledge can reuse in professional (Resnick and Mejia, 2007, p.1714). CoP benefit organisations easy to access more valuable knowledge and practice them in organisations.
Other benefit is new professionals easy to absorb related knowledge and experience by CoP. It is because of they can access other's professionals' experience through professionals' sharing. Meanwhile, new professionals have mentor practice within professional group (Resnick and Mejia, 2007, p.1715). The benefit is a profitable advantage to organisations and professionals and shows the beneficial result of knowledge sharing. However, CoP needs efficient collaboration. I have experience on CoP at information professional's field. I have learnt lots of knowledge from experience professionals. They post their experience or articles on particular webpage and share with other professional. They exchange their knowledge on the webpages, such as they post their challenge of jobs to ask solution or advice. Social network tool is a powerful collaboration tools once it manages well.
