2007 Q4 CROSS-ACCEPTANCE

[adikarina]

Hi!
I have attempted my first exam question for module 1 and am attaching the question and answer in the file below
[Note that this attachment is now actually included in Peter's reply which is lower down this thread- PJW] .
Please review the answer and provide any feedback back to me.
I will be grateful for any quick replies.
If anyone else has attempted this question, please let me know how you went about it.
Thanks
Kind Regards
Aditi

I will post a full reply shortly.... Please bear with me.

I'll hold back from commenting directly on Aditi's answer, but I think that it is important to recognise exactly what "Cross-acceptance" actually is.  I am no expert in this field but I feel that her answer drifted too far from this into the more general issue of introducing products to new markets.

I attach a few pages which I hope are helpful in clarifying- look at it and then the proposed answer and decide for yourself how much of what she wrote was strictly relevant and how she might have presented the same basic thoughts in a way that focussed more directly on cross-acceptance.

I have worded the first part of this in a way that it could perhaps be the introductory beginning of an answer to the overall exam question.
However the remainder DOES NOT attempt to answer the specific sub-questions; the idea is not to give a model answer but just help clarify CROSS ACCEPTANCE.

A good answer to the exam question would instead need to address the specifics one by one as indeed Aditi attempted to do.

Sorry for the delay in posting something, I've been away and then unfortunately had a bereavement in the family, all of which does not help you but I don't want you to feel ignored!

I've attached a copy of your paper with comments added.
[attachment=74]
A couple of things to note:
a) Like Peter W, I'm not an acceptance expert, but I think my understanding of the term gives me enough scope to comment, although I'll be the first to admit, I probably would not have a go at this question myself!
b) There are lots of true things in your paper, but their relevance to the question is a key thing for you to consider.
c) Your presentation in bullet point is a good idea clearly showing the end of one idea / point and the start of the next.
d) Please don't take the comments as detrimental criticism - most of them are intended to be as questions or thoughts for you to consider your answer against.

Hope this is useful and well done for being ahead of the game and putting your head above the parapet by posting something.

Hello Aditi,

I would like to say some of your answers were strong and apt to answering the question. Reading PJW's post and truly understanding cross-acceptance would be useful for you to clarify how to rewrite the answer for the future. I'll add a few comments though.

If a product doesn't meet current standards it may well require modification. However, that would likely mean that part of the system will not be cross-accepted. An example. If a proven track circuit reciever had the software re-written in a different language you would expect the usual software audit against EN50128 and that used to support a cross-acceptance application, if the application was to be considered anyhow.

Someone accepting a product wants to understand what the risks are in using a product, what environment it was used it, the interfaces and complexities of the product and whether the level of safety required can be met.

A good attempt certainly. A little further domain knowledge on cross-acceptance would help you answer the question more fully.

Attched is the answer that I prepared for the 2009 Study Day. It is far from perfect and one of the groups produced some good notes whcih I would like to see written up into a good answer and psoted on here.

It seems to be that this process (as Peter has described) is not unduly complex adn reasoanbly intutive and therefore a question like this could be a useful reserve for someone who hasnt actually been direcetly involved but has doen soem exam prep.

thankyou but I do not know how to get the perfect answer for this question

[As with many questions there proabbly is no perfect answer. hwoever to gain familairity with the area I suggest you read the CENELEC reprot referred to plus the IRSE Technical Reprot on Cross Acceptance which will explain the process to you. You then need to use your skill and judgement and put yourslef into the position of a railway administration and supplier and see it from their point of view. This can;t be taught it has to be experienced or developed.

Added some comment in your text.

Generally a good approach and presentation, but some similarity with Aditi's answer in that you weren't specifically concentrating on cross-acceptance but some was more general, being related to the use of a product from one environment in another one. Hence suggest that you also read the various comments made on her attempt.

I guess marks would be something like 3 +2 + 5 + 4 = 14 so a comfortable pass and had you been a bit more convincincing that you really understood what cross-acceptance is really all about then it wouldn't have taken much more to have got a credit.
