Based on the formula of output by Andy S. Grove, apart from increasing the leverage, a commonly used approach to improve manager’s productivity is time management techniques.

  1. Use the production management principle to identify the ‘limiting steps’ - the things that are immovable. Plan the rest of the activities around them to maximise the output.

  2. Batching to avoid context switching and to save set up costs, both in physical efforts and in mental energy.

  3. Use calendar for forecasting.

  4. Say ‘no’ based on your calendar forecast. This involves active use of calendar - fill the holes between limiting steps with non-critical but necessary activities.

  5. Plan slack into your work. It will protect your schedule from buckling under even the slightest shock.

  6. Build a raw material inventory: discretionary projects. Remember to work on them instead of meddling in your subordinate’s work when you have free time.

  7. Be consistent with your approaches and choose well-established process when possible. Don’t reinvent the wheel.
