How do you ensure knowledge retention in your organization pertaining to the projects that you handle?

At Smartbuzz, we understand the importance of knowledge pertaining to the project and ensure that we deploy a shadow resource for every 5 or 6 resources who work on the project. This ensures that despite the attrition that may happen in the future, there is an extra resource (who will be the knowledge source) pertaining to that project. Majority of our projects have shadow resource deployments in order to ensure safety of our client’s and partner’s projects. Detailed project documentation at all stages of the project also helps us manage the project knowledge.
