Which strategy is not recommended for mitigating problems related to lookup skew?

The strategy of always using lookup fields is not recommended for mitigating problems related to lookup skew because it can actually exacerbate the issues associated with lookup relationships. Lookup skew occurs when one record is linked to a disproportionately larger number of other records, which can lead to performance problems and complexity in data management.

In scenarios with lookup skew, using lookup fields indiscriminately can increase the number of records associated with a single look-up relationship, making it challenging to maintain data integrity and performance. In contrast, the other strategies mentioned focus on optimizing data processing and reducing the number of dependencies on heavy relationships, which can help alleviate issues linked to lookup skew.

By properly managing lookup relationships and potentially utilizing other types of relationships or optimizing existing workflows, organizations can better handle the challenges associated with lookup skew.
