Learn Swedish: Vi noterar att chefen slutfört bedömningen. - We note that the boss has completed the assessment.

This is a classic example of dropping the auxiliary verb (a rule often called ha-bortfall). In Swedish subordinate clauses—like this one starting with att—you can leave out har or hade before a supine verb like slutfört. The sentence means exactly the same thing as att chefen har slutfört bedömningen.

Is it more natural to drop har or to keep it?

Dropping har is very common in written Swedish, news reports, and formal contexts, which fits the professional tone of a boss completing an assessment. In casual, everyday speech, Swedes will usually keep it and say att chefen har slutfört.

If the boss has not completed the assessment, where does the word inte go?

It goes right before the verb! Subordinate clauses follow a special word order where adverbs like inte come before the verb. If you drop har, it becomes att chefen inte slutfört bedömningen. If you decide to keep har, it becomes att chefen inte har slutfört bedömningen.

What words make up the verb slutföra?

It is a compound verb made from slut (end) and föra (to lead or bring). Literally, it means to "bring to an end," which translates smoothly to "complete" or "finalize."
