I have a habit of being blunt, so I guess I don't recommend my method of setting the stage for resigning.
Before I decided to ER, I was actively looking for work. Couldn't take the office's dysfunction or the insecurity of my boss anymore. His insecurity manifested itself in the need to try to control everything, and to automatically assume that only he could be correct about any decision. In reality, he came across as second generation "Peter Principled". My peers and I just nodded our heads at him and then did what we thought was best. He never seemed to figure that out.
Anyway, back on subject, I was called in to his office sometime in April 2014 to discuss my "personal plan", i.e. to hear what he wanted me to work on for my personal and professional development in the coming year. Pay depends on meeting all the "goals", behaviours, and milestones that get incorporated into the plan.
After he'd prattled on for a couple of minutes, I realized that I couldn't stand going through the motions and just blurted out that my plan was to leave the organization. The meeting ended about 5 seconds later.
About a week later, I obtained the CV calculation of my pension buy out and, after assessing our other investments and living expenses, decided to retire instead.
A little less bluntly this time, I informed the director of HR that I had decided to retire, but would stick around until the end of the upcoming audit busy season ( I was the Audit Engagement Leader for three Ministries). That face-to-face meeting was followed-up with a written notice.
Felt good to have the decision formalized.

PS: Anyway, don't be afraid of this, you're in the drivers seat throughout this process
