The best long-term solution to address the concern regarding loss of experienced staff is to implement knowledge management practices, because knowledge management is the process of creating, sharing, using, and managing the knowledge and information of an organization1. Knowledge management practices can help capture, document, and transfer the valuable knowledge and expertise of the experienced staff before they leave the organization, as well as facilitate the learning and development of the new or existing staff. Knowledge management practices can also enhance the organizational performance, innovation, and competitiveness by leveraging the intellectual capital and creating a culture of knowledge sharing2. According to a study by 3, the impact of knowledge management practices on employee retention is significant and positive in both IT and banking industries. Another study by 4 found that knowledge management practices can improve job satisfaction and employee retention by fostering a supportive work environment, providing growth opportunities, and rewarding knowledge contributions. Therefore, implementing knowledge management practices can help mitigate the risk of losing experienced staff and their knowledge in the long run.
The other options are not the best long-term solutions, because they are either short-term or partial solutions.
Establishing a mentoring program for IT staff can help transfer some of the knowledge and skills of the experienced staff to the mentees, but it may not be sufficient or systematic enough to capture and preserve all the relevant knowledge. Determining key risk indicators (KRIs) can help monitor and measure the risk exposure of losing experienced staff, but it does not address the root cause or provide a solution for the problem. Retaining key staff as consultants can help retain some of the expertise and experience of the staff, but it may not be feasible or cost-effective in the long term, and it may also create dependency and vulnerability issues for the organization.
