Henderson's naval politics and Cunningham's fleet command

How did Henderson work well with both the Jellicoe and Beatty factions?

He was skilled at naval politics and ship design, although Cunningham is judged the stronger fleet commander.

Henderson is credited with skill in naval politics and ship design, which helped him work with both the Jellicoe and Beatty factions. Cunningham receives the stronger assessment for managing and fighting a fleet. In the counterfactual of Henderson becoming First Sea Lord, his ability to secure major construction programmes underpins the expectation that large carriers would be built before the war ended. How he would obtain approval remains uncertain.
