PEUSS assignment and later took up the KBAM module sheets. Most of the asset management practices mentioned in the module are practiced in our company and able to appreciate it. The module notes gave insight on why central utility is held alongwith ISD and why contractors are managed by CU in TVSM. Some of the best systems and practices in TVSM like TPM,ISO,OSHAS,....were explained. Not sure how far will others in the group would understand all these things. But felt that there were few repetitions from the area of Finance, which could be accepted due to the relevance. Spent some time on asset management and need to focus on knowledge management in the next few days. Tomorrow morning we (the team) will have a meeting at the learning grid to decide on which areas to focus on.
CRIP process (Catchball process). I did the summing up on learnings of the exercise and went on well. Later we had a team meeting and decided to go through the KBAM material and meet again on Wednesday to decide further course of action.

RBD and its application in this accident. Need to give a try on this. Seminar discussion started with the same few discussion (Gez views on involvement in discussions are acceptable and expected)....came to vague conclusion as we cannot quantify robustness….I differ in this…thats how it would have started for quality….but today we have hundreds of rating systems to do so…If robustness is the future then people will emerge up with quantifying…..Presentations by Graham & Ossie singh gave a feel as if I am sitting in TVSM…..almost all that was stated right from TGR/TGW/top most complaints/approach to the above…everything were similar. During the post discussion the speakers confirmed the teams thoughts during the seminar and they were not sure about the rating ….. comment by ossie singh that reliability and robustness are interchangeable has taken me back…...long tiring day
MTBF to substantiate the life improvement but now some statistical evaluation is possible. Test to improve – fix effectiveness…has its roots on expert judgement…still a doubtful tool as this might be misguided due to the views of one person (more people idea might be confusing ). Testing exercise in the afternoon PAPER CLIP brought out the same issues which I have faced in the company….test results are having too much variation due to test differences,tester differences,test equipment,material…..blah blah. The life was predicted using an extreme accelerated testing (actual usage was 5deg while test was at 105deg), our team should have considered the actual usage first and then started the trials. Moreover we did not make any correlation between a customer usage and the test conducted….may be its just a syndicate exercise and this might not be required. But in a real situation this would have be IMPORTANT. Jane's doubt on assuming the the same trend on the other side of the graph ( measured at 105deg but predicting life at 5deg) was very obvious which did not gain the attention required. In the evening disucussion with TKJ on PPMC….hope will have good dreams.

XYZ. The other teams approach was to see robustness from the perspective of various specialist. Towards the end we narrowed down to reliability, safety and input variation ..further discussion to continue tomorrow. PARIS train crash issue heated up in the team … decided to list the various failures which had resulted in the accident and then try to look fo the tools which would have diagnosed the same. Our team came up with an ample number (25) different reasons or failures for that accident. Will have to work out which tool would answer each problem. LOT TO GO. Have to work on PPMC assignment.

TVSM, preparing a FTA for engine noise analysis. Though that was a last minute work, very well received by the management and still contining it (I believe…). What ever be the tools and techniques be taught everything required a pre requisite : systems thinking and knowledge about the system. Jones' comment on active and passive components, defining boundaries were quite interesting. But when I did work earlier, everything was taken for granted and expected that the assumptions were understood by all. Binary decision diagram was quite catchy but felt a bit trapped. Took long time to understand. Continuous usage might improve my understanding and identifying application areas.
