Play it smart: Show loyalty to all higher-ups. Keep everyone equally apprised of your progress. Never withhold information from some while updating others. Other tips:
Know how they judge. Ask each boss how he will assess your work. They may each have different ways to process information, so tailor your communication to fit their preferences.
Example: The CFO may like raw data, while the chief marketing officer may find one-paragraph summaries more useful.
Follow up. At no point should bosses have to ask each other, “What’s up with that project?” Update them at regular intervals.
