 Dear students, now we are going to see the key challenges in the success of community of practices. And these challenges can be categorized in four types. The first type is management challenge. The second one is the community challenge. The third one is the technical challenge. And the fourth one is the personal challenge. Let's see the management challenge first. And when we talk about the management challenge for the success of the community of the practices, we have to focus on topics important to the business and community members. So we cannot talk about an every topic in online community network, and we have to focus on a particular topic for which the community network is developed. And we have to find a well respected community member to coordinate the community. So if a particular community network is developed for a particular cause, we have to bring a well respected community member who is working on that particular cause and assign him or her our role of the coordinator of the particular community. And we have to make sure people have time and encouragement to participate. So in order to make a community of practice more successful, we have to engage the community members for that particular agenda. And we have to build on the core values of the organization of the community network that how we can improve the community network based on the values we share as the member of the community. Community challenges is the second type of challenges we face for the success of the community of practices. So we need to get key thought leaders involved in the online community network. And we have to build personal relationships among community members. And we need to develop an active passionate core group. And for this, we need to create forums for thinking together as well as system for sharing information. So these kind of things we have to perform in order to make community more vibrant and active. What is the technical challenge when we talk about the community of practices? We have to make it easy to contribute and access the community knowledge and practices. So we have to make a very a less spare type of model to run the community. And we have to to reduce the barriers on accessing community information and knowledge. And the last type of challenge is the personal challenge. And this challenges create real dialogue about cutting edge issues that how can we contribute on the real issues for the purpose that community is developed. So these are the four kind of challenges which any online community of practice face. And if we address all these challenges, we can say that that particular online community of practice become successful.
