If a Franklin Planner counts, then the answer is "yes". I have been an avid Franklin user for years. Every day I have my to-do list, which is mainly a listing of certain things that I have to do on (for example) a monthly basis, such as a certain sales dollar report or a certain quality report.
Any conversation I have that could have personnel ramifications are also mentioned in the planner, such as a disciplinary discussion with an employee.
(Yes, a Franklin Planner can be supoened for a court proceeding.)
Our organization also has Lotus Notes, tied in with about seventy-five computer users in our building. The calendar aspects of Lotus are helpful and sometimes save me from having to write in my Franklin. But, information about employees, etc. is never placed in Lotus, because of security reasons.
Over the years I have tried different journals on the home front, but my life is too boring for any kind of written document.
