Meet Father on the rooftop after The Battle of Bunker Hill. He will request for the Sole Survivor to attend the next Directorate meeting. There, Father will make it public knowledge that he is dying from an aggressive form of cancer, and that he will be appointing the Sole Survivor as his successor upon death.
Speaking with Father afterwards, he will state that it will take time for the scientists to accept that the Sole Survivor will become the new director, but will give assurances that the Sole Survivor will be the future of the Institute, and his legacy.
Finishing this quest automatically begins the next quest, Mass Fusion.

Notes
X6-88 becomes available as a companion after completing this quest.
The player can get banished from the Institute if they start arguing with Father on the rooftop and the argument gets too heated, thus ending the Institute and the Railroad quest lines.
After completing Mankind - Redefined, Tradecraft will fail automatically. Consequently, the player cannot join the Railroad anymore. However, if the player is already a member of the Railroad, they can continue to do Railroad quests.
If From Within has been advanced to the point Madison Li was coaxed into returning to the Brotherhood prior to the meeting, Evan Watson will attend in Li's place. Her absence will not be mentioned by anyone and Evan's responses to the player's appointment as heir mirrors Li's word-for-word.
Some events done prior to this quest may alter what Justin Ayo says during his status report:
If Show No Mercy has been completed, Ayo will comment that the Brotherhood of Steel have taken control of Fort Strong and have access to a large amount of mini nukes.
The meeting will take place even if the player takes too long to arrive by completing other quests before showing up. Mankind - Redefined will still continue, but Father will be alone at the table and chastises the player for missing all of his big announcements.
Similarly, leaving in the middle of the meeting will lead to Father remarking, "Given that some of us have apparently lost interest in this meeting, I think we'll adjourn for now." Talking to him afterward will lead to the same chastisement as above.
Even if the Railroad has been wiped out in the Brotherhood of Steel mission Tactical Thinking, it will be mentioned in the meeting that "...this "Railroad" continues to operate, and is becoming more... ambitious."
Bugs
PCPlaystation 4Xbox One The directorate meeting may never start. All the department leads will be sitting at the table waiting for Father's announcement, but he will only ever say that he has something important to say before he can talk to the player in private. PC players can use console commands to advance the quest to the next stage. This bug also occurs if any of the faction state (i.e killing a faction member) change after getting the quest, but before going to the meeting.[verified]
Playstation 4 One thing that may bypass this bug; head back to where one first meets Father on the C.I.T. ruins after the aftermath of The Battle of Bunker Hill. If encountering Father for the first time, be sure to wait a while on the rooftop after Father beams back to the Institute. If one has already met him in the C.I.T. ruins and this bug occurs, go back to where one would normally meet Father on the roof of ruins; start firing a weapon around. After this, try fast-traveling back to the Institute and Father automatically begins his dialogue for "Mankind - Redefined", even though he is three floors above the Survivor upon first arrival to the Institute.
