Here are some suggestions for matching PM activities to meta-programs:
Outline business case - Big picture, Options
Executive report - Big picture, Options
Options appraisal - Options, Independent
Schedule (Gantt chart) - Detail, Procedure
Risk Register - Detail, Procedure
The idea is that activities like outlining a business case and executive reports benefit from a helicopter view and generating options, while detailed tasks like scheduling and risk management are better suited to a focus on details and established procedures. Of course most good project managers will be able to flex their style as needed.
