Which word refers to lacking detail and focus in a process?

The word that refers to lacking detail and focus in a process is "cursory." When something is described as cursory, it means that it is done hastily and without thoroughness, often resulting in a superficial treatment of the subject matter. This aligns perfectly with the idea of lacking detail and focus, as a cursory approach typically skips over important elements in favor of speed or expediency.

In various contexts, such as reading, analysis, or performance, a cursory effort can lead to missed information or a lack of depth, making it a fitting choice for the question asked. The other words do not carry this specific connotation. For example, to "qualify" means to modify or limit a statement, "culpable" refers to being at fault or responsible for something, and "profuse" describes something that is abundant or extravagant. None of these alternatives convey the sense of superficiality and lack of detail that "cursory" does.
