slapdashly

This term carries a strong negative connotation, emphasizing a lack of care and a disregard for quality. It describes an action performed with haste that results in a messy or incomplete outcome. While "quickly" is neutral, "slapdashly" implies that the speed of the action has compromised the integrity of the work.

In professional or academic settings, using this word suggests a failure of duty or a lack of professionalism. It is most frequently used to describe physical tasks, such as painting a wall or organizing a file, where the visible lack of precision is evident to others.
