As noted in recent blogs, precedents and legal opinions are valuable tools for law firms to ensure they are working efficiently and to high standards of quality. A third tool I believe is essential is having high quality checklists and other guidance, which can help someone work through a processs quickly and safely.
Like precedents, checklists that are well designed, current and comprehensive can be very hard to update and maintain, but as Atul Gawande shows in The Checklist Manifesto they are not just for inexperienced people, and can be essential to reducing mistakes in all fields, including medicine, aviation, construction, finance - and law.
The next question I recommend clients ask their lawyers to find out how they really work, and to identify law firms that are working differently and better than others, relates to checklists, guidance and other quality control methods.
