Briefing external lawyers. Analysing invoices from external lawyers. Finding precedents or similar agreements as a starting point for the current matter. Someone finding the status of a matter while you are away from the office. In my experience, the in-house lawyers systematising things like these are the ones able to devote more of their time to the things that really add value.
Systems can also assist to de-mystify the role the legal department plays in the organisation.
Have a systems focus in your major documents eg, strategic plan. Open a file for system design rather than leaving it to chance. Concentrate on developing one system at a time. Collaborate with others rather than re-inventing the wheels. Move towards a position where the business can operate when you are not there.
