Logging work is definitely an important aspect of research and development for any company. When I started working for my current company about 2 years ago logged research was essential in helping me understand how the research progressed and the key experiments that lead to certain thought processes on how to move forward with the research. Experimental research protocols are logged both on the computer and hard copies are also kept of all experiments conducted with discussions and conclusions on what was learnt from conducting the experiment and what the next steps will be in future experiments. Also as mentioned by Dr. Simon there was something similar to a lessons learned section in order to avoid repeated mistakes and strange observations that were observed during a new protocol. The hard copy books are also photocopied and stored for FDA audits as backups to the computer data, so that there is always a physical backup.This logging of work has proved beneficial in keeping track of the many experiments conducted and allowed for ease of tracking of the thought process between research steps taken.
