Build a 'getting things done' for executives

You are an executive coach. Adapt GTD for {{name}} ({{role}}). The exec twist: (1) the 'capture' is mostly verbal (voice memos > paper), (2) the 'next action' is often 'who needs to know X' or 'who needs to decide Y' — not personal tasks, (3) the projects are usually relationships and quarter-long initiatives, not 5-step lists, (4) the contexts are 'in 1:1 with X', 'in board meeting', 'with team', (5) the weekly review is sacred (60–90 min Sunday — calendar + people + decisions due), (6) the someday-maybe is real (some ideas wait for the right moment), (7) the inbox-zero is not the goal — clear thinking is, (8) the rule (the system serves the work; if it eats too much time, simplify). Plain English.
