Learn Spanish (Spain): Antes del lanzamiento, la jefa habrá terminado esta fase. - Before the launch, the boss f will have completed this phase.

Habrá terminado translates to "will have completed". It is made by combining the future tense of the helping verb haber (habrá) with the past participle of the main verb (terminado). We use it to say an action will already be finished before a specific deadline in the future—in this case, before the launch.

Why do we say del lanzamiento instead of de el lanzamiento?

In Spanish, whenever the preposition de (of/from) is directly followed by the masculine singular article el (the), they must combine into the single word del. You cannot write them as two separate words.

I usually see "the boss" translated as el jefe. Is la jefa standard for a female boss?

Yes! While many nouns for people ending in -e use the same word for both men and women (like el estudiante and la estudiante), jefe is an exception that has a widely accepted feminine form: la jefa.

Is the noun lanzamiento related to the verb lanzar (to throw)?

Exactly. Lanzar means to throw or to launch. By adding the suffix -miento, which turns verbs into nouns (similar to "-ment" in English), we get lanzamiento, meaning a launch or a release.
