Win Ver 3. 6 there is the ability for the PMO to view the Obs on screen in traditional logbook coded format whilst on board the ship v IMMT data not easily readable, but new option allows PMO to view the Obs for monitoring purposes

PMO-III, 23 -24 March 2006, Hamburg. QM Feedback to Ships v v v 13 Vital that NMS provide feedback on Obs quality and quantity to National VOS Real-time feedback via PMO visit, email, or phone call is most effective as targets current observers Feedback on problems should be done in a manner to encourage and assist observers Most ships view feedback whether good or bad as positive as it demonstrates their Obs are being used Always include some thanks and encouragement in feedback messages
PMO-III, 23 -24 March 2006, Hamburg. Use of the Monitoring Tools and timely feedback to ships to correct problems will improve the quality and quantity of Obs provided by VOS 14
