The Oil Spill Commission's charge was to find the root causes of the disaster, and the addendum says that the technical root cause is clear: Cement pumped to the bottom of the well by BP and Halliburton didn't seal off hydrocarbons in the formation.
While Halliburton disputes that, BP's own investigators have agreed that the cement seal failed.

But the Oil Spill Commission still traces what happened back to management lapses. BP failed to recognize the cement's failure during a critical negative pressure test and misinterpreted its results, the addendum says.
