Cell Manufacturing

I found the concept of working in small batches very interesting. I f one makes different types of products too, it important to alternate between the two products than just making product A in the morning and product B in the evening. This is called product levelling. It also involves producing goods at a fixed speed. There is standardization then. Its not the one day you produce more and the other day you produce less. By working in small batches one can detect defects more easily and reduce the lead time and changeover time. The WIP inventory is reduced.

Time Management

Well in our presentation we ran out of time and could not complete it. Well most of our team members were quite dissapointed, as this was the last presentation we would have and we all had worked very very hard on it. In the assesment we got from  team 1 was that we had good content in it. I tried to evaluate where we had gone wrong. Why did we not finish. May be because we spent too much time explaining definitions.

I have definately learnt how to be more careful and manage time more effectively by prioritizing whats more important. I think I came out a winner from this presentation and not a loser. I have learnt so much during the course of this presentation. We all discussed what we were talking about in the presentation, gave our inputs to each other. The team worked very efficiently. The portfolio was a good way to reflect on the ideas in the presentation.

It was very nice for a lot of class mates to say that they felt bad that we could not complete the presentation. This shows cooperation and unity and not competition. I think all groups did a really good job and as Paul said in class, that we all have come a long way from presentations we gave in CBE about 4 months back i think.

Lean and Six Sigma

I just turned in the pma a couple of hours back. It sure has been very interesting. It was interesting to see how lean and six sigma can be used together. Both have similar goals of minimizing defects, and are quite similar in many other ways.  One of the only difference I found was the lean also emphasises on compressing the process to reduce the lead time, which probably six sigma doesnt really work on. Both also use stastistical tools to solve problems and have a cylewhich helps them solve problem. What I found interesting was the use of hoshin kanri in lean. PDCA cycle is a huge part of lean culture which is a part of hoshin kanri too. Honshin kanri can be used in a lean company. The Catch ball method is a good way of brainstorming. Six sigma too talks a lot about brainstroming and having cross functional teams which would help improve the quality of brainstorming. It is very important to have a facilitator in a six sigma team who is a black belt, who will encourage comunication between members and try and create an environment of trust. There are so many other ways how these are similar. Its interesting to see so many companies such as Xerox, Ford adopting lean six sigma.

Health and Safety

During the presentation Billy talked about having the right uniform and job safety accessories such as helmet, gloves and so on. If such things are provided then people are bound to be safer. In India many a times I see that people dod not have the right accessories and get hurt. It is very essential to provide the workers with the right accessories. I know this is a very small blog but I hat to emphasise on the imporatnace of people having the right accessories and every life is important!!

I also wanted to talk about that keeping things such as toilets, kitchens, work place clean would help motivate the workers come to work apart from keeping a disease free environment..... One should try to abide by standards provided according to me. ....


In maintenance while researching, I thought having a maintenance technical library was a really good idea. You can store all your previous problems and solutions in it. So next time if something similar happens you have something to refer to. It will save so much time and cost of trying out something new. I thought benchmarking maintenace to the previous years maintenance cost is a really good idea too. Hopefully the trend should be downwards after applying different sort of maintenance like preventive, predictive or TPM.According to me preventive is based on Murphy's law which states that if anything can go wrong it will. Therefore take all the precaution. See that all the bolts in the machine are tight, the environment is clean, everything is in place

One of the groups talked about lean. I think its a good idea to stop te line wen you see a defect. Instead of of having a lot of rework which will increase cost, one can save a lot of money. This will definately help me to imporve the quality for the place I will work. Interesting idea.
