Final answer:
The three main types of data in CSM and Knowledge migration are qualitative data, quantitative discrete data, and quantitative continuous data, encompassing customer feedback, ticket counts, and support call durations respectively.
Step-by-step explanation:
The three most common types of data encountered during a migration for Customer Service Management (CSM) and Knowledge are qualitative data, quantitative discrete data, and quantitative continuous data.
Qualitative data includes non-numerical information such as customer feedback, service level agreements, and process descriptions. This type of data is important for understanding customer satisfaction and the qualitative aspects of customer support interactions. Quantitative discrete data involves numerical values that are countable, like the number of support tickets handled by an agent or the number of articles in a knowledge base. Lastly, quantitative continuous data represents measurements that can take any value within a range, such as the time spent on a support call or satisfaction scores that can vary along a spectrum. Each of these types of data plays a critical role during migration, supporting decisions and ensuring the smooth transfer of valuable information.
