Anything can be made to sound ridiculous if you try. Especially if you change the words in the process. If things don’t make sense, then a first assumption should be that you don’t understand something. And you ask polite questions. Perhaps you misread something. Perhaps the writer mistyped something. Perhaps it just wasn’t explained well or completely. Perhaps your question will spark something that the writer hadn't thought of. All of these are better explored with questions than indignation. Here is a summary of what was done 1) a consensus was reached some time ago that we should figure out which items were objective and which were subjective. The goal is to make as many items objective as possible since it is a problem to have a 'checkpoint' where people can't decide or determine if it has been met reliably. 2) we also said some time ago that we would have to test our guidelines this time before we released them. 3) those people on the weekly conf call consensed on a test for whether something was objective and we posted the test to the list for comment. 4) Then we began to examine our guidelines to see if we thought they would pass or fail the test when it was done someday. This is what any developer does when designing. - They figure out what they are trying to achieve. - They develop a test criterion for determining if they have achieved their design goal. - Throughout the process of design they look at their work and see if they think it will fail. If they judge that it will, they work on that aspect. These guesses are not in lieu of the real testing. They are just to get the item ready for testing and to remove any obvious errors that they can pick out by just looking at it. As we get our guidelines in better shape, -- and remove all the problems that we can see ourselves by just looking at them, -- we will move into testing them. They need to be tested for a number of different things including (but not limited to) - objectivity - do-ability - understandability - usability etc. We will need to carefully design each type of test and figure out who the test subjects should be etc. as well as seeing if the different tests can/should be carried out together or separately. I will be posting another document on our overall procedures but I have to run to a presentation I'm giving this morning. Greetings from Brussels.

In my last email, I said: So 80% of people, who meet subjective criteria for inclusion, then make subjective determinations, and if they happen to agree, we label this "objective"? Apparently the way we are using our newfound "objectivity" criteria is as follows: A group of people -- who may or may not meet subjective criteria for inclusion -- "reach consensus" on whether or not they subjectively believe that at least 80% of an undefined group of people -- who meet subjective criteria for inclusion -- would make agreeing subjective determinations on arbitrary undefined specific applications, ... and we label this "objective?" This is newspeak of the worst kind, folks. If we want credibility for our work, we don't suddenly label as "objective" things which are clearly and absolutely subjective. A subjective decision doesn't suddenly become objective if you vote on it. The specific process you've defined may or may not be useful and I'm not suggesting we reject that out of hang -- but if you keep it, you MUST rename it to something else OTHER than "objective." --Kynn -- Kynn Bartlett <kynn@idyllmtn.com> http://www.kynn.com/
