It only LOOKS like he's winning - not that it's a contest.   :o

Just wait 'till I define "mutable" and "As-Was" (in this context).  ;)

I'm fairly certain an 'appeal to the future' is a formal logical fallacy :-) 

Hi all,
I have the feeling that the issue is in general, overall just too complex to be remarkable supported by a kind of algorithm.
First some Remarks.
Models have typically the purpose to describe something that exist or should exist in future. The terms like As-Was, As-Is, To-Be, Might-Be, can be applied to both, the model itself and to the thing it describes.
Both, "the model" and "the thing", might be mutable depending on one defines what mutable means, even in state "As-Was" depending on what "As-Was" is applied to.

I think Peter is currently winning :-)

General Board / Re: Choosing a tool

Your point is well taken, but with regard to universal access...  I think many modelling projects fail because most people actively (or at least passively) resist modelling.

We (at my workplace) experience this.  We, therefore, concentrate on reducing any friction encountered by our users in using the tool.

Because - to an extent - modellers are born not made.  Which is why universal access is a prime consideration.  It's not going to the people you think who drive the model forward.  Most modelling tools get wasted on a bunch of opinionated self important architects. :-)

I couldn't agree more with this, and in general universally if you refuse to allow the chosen platform to drive requirements you will end up with a complete mess that combines weak least-common-denominator fulfillment of functional requirements with the massive bloat of "platform independence."

I've seen quite a few modelling projects fail.  The thing common to them all was taking the traditional approach of gathering requirements, evaluating the tools in the market, and then choosing the tool that best fulfilled the requirements.

What ever project failed to realise is that near universal access to the tool is required for modelling to be successful.  None of the projects had the lowest price per seat as a requirement.

General Board / Re: From UML to SysML for Systems Architecture
« on: May 04, 2018, 07:01:59 am »
As said, I was happy with plain UML and setting up my own profile having borrowed from SysML (it was rather hardware oriented). I'd probably recommend that in most cases. Sticking to pure SysML (or pure UML) as bible isn't reasonable (except you have forced requirements for what ever reasons). I think the key is setting up a good profile for the domain you're working in.

Isn't reasonable if you know what you're doing.  Where I see a lot of people going wrong is trying to get too fancy before they really understand what modelling really is.

As part of our possible future solution description, we have a "Transition diagram", where we place the model items (vertices and arcs) in the current state. We then add the future items and connect the current and future things with a "Transitions to" relationship.  With EA recent ability to allow relationships between relationships and relationships and items, we can specify what the transition will be to the requisite level of detail.  It's a really easy way to see if we've "considered everything".

You've discussed the what but not the why.  I suspect that that no one who has commented so far has the same reason for wanting time aware modelling, or potentially for the same notation (where).

Does that mean we've nailed it?

I started thinking about how your summation was predetermined by the grammatical tense in English and sunk slowly and quietly into a epistemological fugue state.
Surely you "sank into an epistemological fugue state".    ;D

Does one mean the simple past irregular verb, how does one know?

Hi I suggest you have a look at the TOGAF Architecture Content Metamodel.  I don't endorse TOGAF itself but the content metamodel is a good starting point for a discussion on what you want to achieve. 

Hi there,

I'm wondering whether anyone knows of an MDG that has been developed for the Essence Language.    (

It has similar purpose but distinct differences from SPEM 2.0 ( which does have an MDG.    I have a client that may be interested in this, so just checking to see if anyone here can point me in a good direction.

Not that I found (I looked at it when first working for the bank).  Might not be hard to write tho'.

General Board / Re: EAUML Information?
« on: April 30, 2018, 06:57:55 am »
I'm using EAREQ which seems to be part of EAUML. I can't find any documentation on EAUML or EAREQ. I'd like to understand it better. Is there any information

Only what's in the help, and there's a white paper on managing requirements with EA.

But, basically, it's sitting in on discussions and listening to how people are miscommunicating and helping sort it out when we see it.

More and more - when people ask me what I do - I say I am a therapist for technology.  :-)

So far, I'm getting best value from Q's response.

I've spent a bit of time helping ex-Aris users to get value out of EA after Aris has failed to deliver the value that was in the business case to buy it.  But I don't know enough about the actual reasons that it didn't live up to the promise to give you much of a steer.  I suspect - like any tool - you need "modellers" in your organisation, as nothing does it for you auto-magically.

Thanks, I'll open a new thread. Try and be less aggressive, it does wonders.

It's a mistake to read tone into written text.  English as a language is pretty global and some native speakers use very terse dialects.

Also there have been a rash of people resurrecting old threads in the last week, including one person resurrecting multiple on the same subject.  Which gets pretty annoying for the regulars.

Wouldn't it be preferable to resurrect old threads of the same issue than create a new one and clutter the fora?

No.  This is a user forum provided by Sparx for users.  You're complaining about a bug in the addins board not the Bugs and Issues board.  If you're complaining about the issue with version 9 like the originally poster you're using a version 5 major versions and about a decade back.  If you're not, you're being doubly as confusing.
