A workup is an efficient way to diagnose an ailment by conducting a series of tests. However, often the word workup is replaced by other synonyms to avoid using the same term in various documents. Some of the synonyms for workup include evaluation, testing, assessment, examination, diagnosis, and investigation. All these synonyms have different connotations and usage that can be appropriate in different contexts. For example, if an individual's condition is novel, the term investigation would be more suitable than workup. Likewise, when a company is conducting a review of its employees, the term assessment is more appropriate. Therefore, the use of synonyms helps to bring variety and precision to written or oral communication.
