The decisions include appointing one Victims Commissioner and the future of the Maze prison site.
The First and deputy First Ministers also said "considerable progress" had been made by the working group to agree on a Cohesion Sharing and Integration Strategy, promoting better community relation and greater integration.
But the UUP has accused the two leading parties of contempt for the political process and deputy leader John McCallister said the announcement highlights that the Ministers "are not interested in inclusive politics".
"The timing and manner of the announcement by the First and deputy First Minister demonstrates clearly the contempt they hold for the political process," he said.
"Only if all parties are actively engaged can genuine agreement be reached."
Peter Robinson hit back at the Ulster Unionist Party's withdrawal from the group, which he labelled "totally irrational behaviour".
"I suspect it's more to do with the fact that the party leader's on his holidays and John McCallister thinks that he will run the party in a different way," he told UTV.
But Mr McCallister dismissed the First Minister's comments as "ridiculous", adding, "Mike had been informed of the decision."
Mr Robinson said a couple of outstanding issues were expected to be concluded by the end of the summer, leaving ministers free to fulfil their commitment on a cohesion, sharing and integration strategy, hopefully at the beginning of September.
No agreement has been reached on the future of the Department for Employment and Learning, which Mr Robinson and Mr McGuinness indicated would be scrapped.
They are content to await discussions with the other parties on the future structures of the Executive, including the number and shape of departments.
