JPB @JPB  Reputation - 0 Rank - Aluminum | Is anyone aware of standard ratings for severity, occourance & detection for use in IT? |
Marc Richardson @Marc-Richardson  Reputation - 0 Rank - Aluminum | To answer succinctly, no. However, I would start with the Automotive Industry Action Group (AIAG.org) FMEA Manual, which does contain the rankings for automotive manufacturing, and do a little thinking about the parallels between manufacturing a product and doing whatever it is you do, whether it is developing software or providing IT services. It should be relatively simple to convert their Severity, Occurrence and Detection rankings into something you can use.

Jeremy Green @Jeremy-Green Reputation - 0 Rank - Aluminum | First of all I’d want to know what type of FMEA you were wanting to conduct, system, design, process, or machinery/equipment.
A good reference source is Stamatis, D.H. 1995. Failure Modes and Effects Analysis. Milwaukee, WI: ASQ Press. It discusses system, design and process FMEAs and has a chapter on Computers: Harware and Software.
The best reference source for equipment FMEAs is: Givens, Gary R. and Sroka, Kenneth J., 1996. Machinery Failure Modes and Effects Analysis Handbook. Ford Motor Company,

David Ropp @Dave Reputation - 0 Rank - Aluminum | SAE wrote an excellent guide on system, interface and detail FMEAs that shows the reader how to coordinate a complete design and development effort. It is called ARP 5580. |
Yury @Yury Reputation - 0 Rank - Aluminum | Hello,
I’m new to the Forum, my first question is..
does anybody has references for FMEA implemented in IT department inside health industry organisation? Is it applicable well or that should be changed to newer standards like ITIL, ISO-17799?
some links: http://www.iso-17799.com, http://www.itil.co.uk, http://www.bsi-global.com, http://www.itsmf.com/bestpractice/sourcebp.asp
Thank you and regards,

Biju. T @Biju.-T Reputation - 0 Rank - Aluminum | Which of the above factor ( Severity, Occurence,Detection) is difficult to improve & why? |
Stan Mikel @Stan Reputation - 0 Rank - Aluminum | All of them are difficult to improve. This improvement game is tedious and detailed. There are no easy answers. |
Nitin Sahni @Nitin-Sahni Reputation - 0 Rank - Aluminum | biju - In process FMEA’s, first priority is given to reduction in Occurance ratings
Severity Reduction requires Design chanes (heavy on resources and time consuming) and reducing detection rating is getting ito reactive mode.
Hope this helps…. |
John J. McDonough @John-J.-McDonough Reputation - 0 Rank - Aluminum | Biju
At 50,000 feet, I agree with Nitin. But in the real world, these things are dependent on what the actual risks are. Sometimes a problem only becomes severe because you can’t detect it, and improving the detection is frequently very easy. Other times you might not be able to affect the occurrence, and your only choice is to bite the bullet and do something to reduce the severity.
These tools are only tools, we still need to apply a heavy dose of common sense to decide how to interpret them.

Shanmugavel. P @Shanmugavel.-P Reputation - 0 Rank - Aluminum | This is a great pleasure to view this IT FMEA. Because till yesterday we were thinking how we can convert this FMEA (which is purely assigned to automobile industry) into IT industry and we had assigned resource to do this job. Now we have got the Severity, Occurrence and Detection details which is published in this site. Definitely this will be very much helpful to our organization. |
mohssen @mohssen Reputation - 0 Rank - Aluminum | HELLOW SIRS
please send me any information about detection number in FMEA.
thanks a lot.
|
mjones @mjones Reputation - 0 Rank - Aluminum | Presuming you are using a scale of 1 – 10: A low number of 1 means you will detect the failure virtually every time it occurs and you will have ample opportunity to prevent your customer from ever seeing the failure. A middle number of 5 means you will detect it about half the time; a high number of 10 means you will rarely detect the failure and you will deliver virtually all of them to your customer. Numbers in between reflect relatively similar risks/expectations. |

Need to know more about your post message-

Helper17799 @Helper17799 Reputation - 0 Rank - Aluminum | Just to point out that iso-17799.com is currently moving to http://www.17799central.com
On the wider point for this standard, a new perhaps more relevant development is the publication of ISO 27001, which can actually be certified against (unlike ISO 17799).
For information on this you could take a look here: http://17799-news.the-hamster.com/breaking-news-2.htm
Hope this helps.

No std rating for IT. Me in LED manuf , I have to make one using the Ford FMEA tables as a guide.

Andy Jr. Talaid @andy Reputation - 0 Rank - Aluminum | FMEA Third Edition is latest for TS16949. It is not out of date . Perhaps you need to customised for your inductry to reflect your manufacturing . I ndid mine for lED manuf.

Pingala @Pingala Reputation - 0 Rank - Aluminum | I think the value for ”probability” is less than or equal to 1. So, we should not the term probability. But, we can use the term “occurance chance” between 1-10 for FMEA analysis. |

Jayne @Jayne Reputation - 0 Rank - Aluminum | Thanks for the links Yuri. Some of them have changed though:
http://www.iso-17799.com has gone to http://www.27000.mobi because the standards has been renamed to ISO 27000
http://www.itil.co.uk has gone to http://best-management-practice.com because ITIL has been devolved.
These still seem to be the dominant standards/frameworks in the arena.

KL @KL Reputation - 0 Rank - Aluminum | Hi
IS there a logic behind the scale of ratings for severity , occurence and detection ????
Can it be limited to 1-4-7-20???
|
Don-Strayer @Don-Strayer Reputation - 0 Rank - Aluminum | Yes! If you use 1-10 but you cannot consistently explain the difference between 7 and 8, for example, your scale is too granular and may give deceptive results. Typically the ratings in an FMEA are not actual measurements and a scale such as 1-4-7-10 will give you more accurate results. Your educated guess may become a wild guess if you’re trying to decide between 7 and 8 but you can be more confident about choosing bewtween 7 and 10. Also note that an FMEA is best done as a team activity. A less granular scale is better able to exploit the collective knowledge of the team and to avoid time wasting discussions to resolve subtle differences. |
Mark Sinnicks @mark Reputation - 0 Rank - Aluminum | Hi all.
I have been reading this thread with interest.
I work within Availability Management and strive to predict the reliability/availability of the service (eg VoIP), Identify SPOF’s, critical items, raise any potential site failover risks and predict frequency of Severity Level Incidents.
I have been using a modified version of MIL-STD-1629. I chose this because of my Aerospace Reliability/Availability/Maintainability/Safety background. It was a great standard to use for guidance, but as with the Six Sigma version, it only deals with single failures. This only does half the job and had to be adapted to make it more credible and add value in the service management and service delivery domain.
Instead of using criticality, I have tended to use Failure Mode MTBF, because to the execs, this can be measued against for validation. A criticality value between 1 and 10 cannot be used as metric. Also it give service support something to work with when it comes to providing network support and for planning Changes.
My comment is basically that you really have to work out what it is that you want to get out of the FMEA/FMECA/CFIA and what value the extra work of calculating a criticality in the traditional way is actually bringing.
I would appreciate comments, thoughts and feedback as I am still developing this.
We are alo looking to set up an Availability Special Interest Group in the ITSMf (http://www.itsmf.co.uk/) work space if anyone is intersted.

Don-Strayer @Don-Strayer Reputation - 0 Rank - Aluminum | FMEA helps identify and prioritize but you really need additional tools to do the causal analysis. Search this site for “causal analysis” and you’ll find several entries that discuss using SS tools for CMMI causal analysis. |
