[SystemSafety] FMEA draft international standard

I detest the 'walled garden' approach of these organisations, what they're
doing is simply rent sitting on a social good. And their bureaucratic
processes have become an end in themselves.

Also, now Peters riled me up, speaking as an antipodean there's about the
same likelihood of the snow dog catching the cinder cat in the furnaces of
hell as there is of my being able to contribute to the development of the
FMEA standard. Which won't stop our national standards body from adopting
it, mainly because they can make a profit on the exercise.

Oh and IMHO writing standards without any reference to what the thinking
and evidence that they are based on is inherently a flawed process,
irretrievably so in my opinion.

I say a plague on all their houses. Somewhere along the line we seem to
have completely lost the point about all this.

But getting such a process underway is not trivial. First, people have to
obtain a copy of the CD.


The UK committee is BSI DS/1

Members of the supporting organisations should obtain a copy direct from
their representative on DS/1

The Supporting organisations are at the bottom of the page at:

If I may take the opportunity to use Barrie's helpful message for a purpose
for which it was not
intended.....

I am very concerned, as are other colleagues, about the restrictive
practices involved in standards
development. There are two sides to it.

One is that some form of organisation is required, resources for any
activity have to be sourced,
especially an activity such as codifying the state of the art in a specific
technology while
controlling as far as possible for special interests, and the world is a
very complicated place.

Another is that the sum total of practices discourage much participation in
the endeavor, and the
results suffer technically. Many standards in some areas are unnecessarily
technically poor.

For example, John Knight has complained publicly that he cannot obtain
copies of standards to which
he has himself contributed as a committee member without paying out large
sums of money to which he
does not have access in his academic role. And his students thereby cannot
study them. He is right.
Almost all academia is hindered from using actual - even past - standards
in their teaching, at
least in the area in which I work. That seems to be absurd if the
standards' claim to codify current
state of the art is true.

Some national standards organisations do make provision for this. In
Germany, a flat-rate
subscription somewhat less than the current cost of a leading journal buys
an organisation access to
any German standards relevant to its area of interest. So I could get
anything produced by IEC SC
65A (the functional system safety people) or IEC TC 56 (the Dependability
people, which in the IEC
definition does not include safety, although in the IFIP glossary - Laprie,
Randell and co - it
does) - but only in its German translation (to which the responsible
national standards organisation
DKE has copyright - the official German standard is the translation of the
IEC one).

Then there is the business of soliciting input and commentary from those
with expertise who are not
involved in development.

BSI appears to distinguish two phases, a Committee Draft and a Draft for
Public Comment. The
proposed IEC 60812 is not available as a Draft for Public Comment on the
BSI WWW site. The German
DKE does not distinguish such phases, as far as I know. A Committee Draft
is made available to any
who have registered a legitimate interest in the work of a given committee
(the German correspondent
to BSI DS/1 is DKE K132). Registering an interest is open to anyone, and
you will be accepted if it
looks as if you work in the field or a related field, and often even if you
don't.

For example, I imagine any member of the VDE (the German electrotechnical
engineering organisation)
would be enabled to register an interest in any standards area for which
DKE is responsible. Whereas
I note that the British equivalent, the IET, is not a supporting
organisation of DS/1, so you don't
get to comment on the 60812 CD merely through being an IET member with an
interest. (Incidentally, I
find it very odd that the IET is not. I think we should fix that. HAZOP and
FMEA and FTA and ETA,
let alone Markov modelling and so on are important to electrotechnical
engineers!)

IEC CDs, NWIPs and so on are distributed, and comments are requested -
commentary is expected to be
solicited by those who have registered an interest. So for example I gave a
recent CD of another
standard to a particularly talented student for commentary; he sent in
extensive (and worthwhile)
comments, which were forwarded to the IEC MT (though had not been addressed
by the time I resigned
my MT membership, which was at the time that the subsequent CD was being
distributed - one
procedural anomaly amongst many, which is why I resigned) and he was
invited to participate in the
subsequent K 132 meeting. Comments are sent direct to the named German
Representative on the IEC
Technical Committee (each participating country has just one Representative
on a TC; this is a
different role from that of participating in a specific Project Team or
Maintenance Team, which is
nominally not tied to nationality).

So I regard the German regime as appropriately technically liberal in this
regard; the British and
US ones much less so.

Then there is the matter of affordances/hindrances, to use the
Nielsen/Norman terminology.

As I mentioned, the IEC (and by transitivity the national standards
organisations) only accept
comments on their comments form. This is commendably targeted in that it
requires not only a general
comment (usually expressing a criticism) but also a specific proposed
change, and has a column for
committee response. Formally, a committee response to each comment is
required. The "committee" of
first instance here will often be the national committee, which will decide
which comments to
forward to the IEC PT/MT. The affordance here is that comments get logged
and responded to in a
traceable manner.

*But* the form is in a proprietary document-preparation format, and is not
formatted for easy use on
the screens of computers which most of us use. I just got a brand-new Apple
MacBook Pro, which
renders the file automatically using its own doc-prep SW Pages, and it is
as usual all over the
place. I can of course deal with that and will. But I am involved in
standardisation work, and many
people whom we hope will comment are not. Many of them are not going to
take the half-hour to couple
of hours to configure their computers just to use a form. It's a hindrance.

What happens in Germany is that free-form comments are de facto accepted,
and someone usually
volunteers to wedge them into the IEC format for further consideration, all
very informal. As far as
I know, that doesn't seem to happen in Britain.

All in all, a reverse of the usual cultural stereotypes. :-)

John is concerned about access to standards and standards development for
engineering students, as
am I (but as I mentioned, we have some sort of a solution, at least for IEC
and ISO although not for
RTCA or EUROCAE, in Germany). I am very concerned about the technical
quality of published standards
in our area, as is John, because it so often is poor. I think FDISs (the
final draft standard)
should be subject to eminent-peer review. I think the EU project regime
here is quite effective.
Named outside reviewers who engage face-to-face with representatives of the
Project Team and who
have final say on whether Deliverables (documents and SW) are accepted. (It
is more effective than
academic-style anonymous reviewing, because *everybody's* reputation is
publicly on the line at
every step. For reviewers to miss things is just as consequential as for
the PT to miss things.)
Resourcing this is an issue, but one imagines that the IEC could find a way
from the kinds of
four-figure sums it charges for the likes of IEC 61508.

John's paper at SSS2014 is available at
http://scsc.org.uk/paper_126/protect_reg_01-Knight.pdf?pap=933 . I have a
White Paper on it from a
year ago at
