Final answer:
A stakeholder's role in implementing and maintaining the CMDB involves determining specific CI information required to support capabilities and gain organizational buy-in through gathering information and conducting root cause analysis.
Step-by-step explanation:
In the implementation and maintenance of the CMDB, a stakeholder plays a crucial role in determining specific Configuration Item (CI) information needed to support the organization's capabilities and gain organizational buy-in. This involves gathering information from customers and other stakeholders, finding expert information, and conducting a root cause analysis to identify the real problem. Monitoring server performance in real-time and developing software applications are not directly related to a stakeholder's role in implementing and maintaining the CMDB. These tasks are typically handled by IT administrators and developers respectively. Conducting market research for the organization is also not a stakeholder's role in relation to the CMDB. Market research is usually done to understand customer needs and preferences and may be relevant to developing new products or improving existing offerings, but it does not directly impact the CMDB implementation and maintenance.
