These are the levels that work for me:
Next Actions = Runway
Projects = 10,000 ft
Objectives = 20,000 ft
Goals = 30,000 ft
Roles/Responsibilities = 40,000 ft
Values = 50,000 ft
Goals are general, can correspond to a vision and are geared to a 2-5 year timeframe. They are high level and set the context for Objectives. I define goals for specific roles and/or responsibilities.
Objectives are measurable and have a due date. They are typically the output of yearly planning exercises. They define how I will achieve a given goal.
Projects are again measurable, have a due date and may contain one or more deliverables and/or milestones.
