General Board / Re: BPMN relocating elements
« on: December 18, 2014, 03:20:20 am »
I currently also use classifier with data objects and data stores though.
Going through the BPMN suggested links, e.g.:
DataObject.itemSubjectRef -> ItemDefinition.structureRef -> Class
... is quite cumbersome, AND besides the ekstra Work it also results in:
- poor visibility of the mapping
- looong chain in the mapping traceabilitiy

Link a swimlane to its performer by Ctrl+L  (Instance Classifier)
I never reuse swimlanes (pools or lanes). But I link each swimlane to its performer by setting its instance classifier to a UML element - business actor or other business object (e.g. baggage belt) performimg the activities in that swimlane.
This may not be a BPMN feature but a UML feature (?). But it Works nicely (so far?) in EA. And the performer is displayed on the diagrams like: "Swiwlane Name : Performer". Sometimes I leave the swimlane name empty - but if I can I give it a name representing the activities in the swimlane.
This also works nicely in the traceability window. For each actor I can see the set of performed swimlanes across processes - and the activities withing each of the swimlanes. In that window, the benefit of naming each swimlane for its own context really shows.
I imagine a BPMN export will ignore this instance classifier (?)
I hope this will still be supported (?)
... or that the proper BPMN entity/rolename will displayed on diagrams in upcoming versions

General Board / Re: HELP! - BPMN connectors dancing allover ! ?

Thanks for your input (and support  8-))
I have tried all of the above suggestions.
And yes it is worst around gateways - very often it Sticks to the corner opposite of the desired one!!!
It is certainly the top complaint in my organization.

General Board / HELP! - BPMN connectors dancing allover ! ?

HELP :-/ :-)
When we create BPMN diagrams, we spend a lot of our time desperately trying to make e.g. the sequence flows position as we want - but they are dancing all over.
I'm sure we are missing some point here - what is the trick to make the connectors fall into the lines where we them?

(Currently on EA 10 - will be on EA 11 by January)

I've found Separating the the objects under one package tree and managing the objects via the phase attribute whilst putting the diagrams in another package tree structure with as-is and to-be in separate packages
  

Thanx Sunshine,
I think I get the idea ;-)
I don't think it will work in our secnario.
- we rely heavily on diagrams being placed contextually with the individual elements
- changes for one single project/initiative are scattered around in the repository

But I do agree that, if we try to do a split model, two sets of diagrams will play a key role. Diagrams are essential to the disgussions/comparisons of asis and tobe (EA compare is far too detailed for getting a high-level gap analysis, although it might be used in an automated mechanism)

In general my experience is to avoid it all together.
...
We just have one model, that is part AS-IS, part TO-BE.
...
is used not only in small shops, but even in the biggest corporate multinational organisations.
...
The only exception I see right now is when you do full MDA.
...

Thanx Geert. The mixed model is what we are doing now.
I anticipate some requests for doing some kind of split model. The upcoming discussion would be easier for me, if I had some references to those big companies that you mention. Could you mention some of them here? - or perhaps just your own company - as far as I remember you have 2-300.000 elements in yoour reposirtory?

MDA: No we don't generate any code at all. We use EA for an enterprise model (Strategy-capabilities-processes-business concepts-IT applications,database-IT Infrastructure).

Thanx Qwerty, Those are good links - at least in the way, that they tell me, that  there really isn't any ideal solution (far from it) - when that's the cae, at least it is good to know so.

Yes, this time I did get a match on ONE post.
That is the one post you see above - LOL

Of course I searched on it before I posted !
I searched on "AsIs", "As-Is", "ToBe", "To-Be"
All four searched gave zero result.
And I WOULD expect those search criteria to match relevant posts. ! :-)
I only searched under the general board though.
...
Any way - I'll have another go then ...

General Board / How do you model AS-IS/TO-BE in EA?
« on: December 04, 2014, 02:38:44 am »
I would very much like to hear experiences from other EA users:
How do you model AS-IS/TO-BE in EA?
E.g.:
- In the same repository?
- In different repositories?
- How do you merge To-Be into As-Is?
- Good ideas for GAP analysis?
Hope very much to hear/see some good suggestions/experiences :-)

General Board / Re: BPMN Called activity: Name synchronization?

Then simply re-use as a Link all other process diagrams, where these Activity is called.

But that ruins traceability. And the individual flows into such an activity would split into all the other flows exiting from that activity from all of the diagrams - unless I test on the diagram together with the flows/activity in my reports.

However, it is convenient to have an option to show up the label in this format,
callActivityName : calledElementName
...
If that's the case, then this might be a feature request.

That is actually exactly what I had hoped for. On BPMN Lanes I set the classifier to be the actor from my concepts UML model. And that works, as you described above.
I tried that on the BPMN Activity, but it does not have a similar effect.

General Board / BPMN Called activity: Name synchronization?
« on: November 27, 2014, 10:00:22 am »
Did I miss something - or is it correct that EA BPMN does not offer me any name syncing for "isACalledActivity" activities:
- I have to specify names redundantly, manually
- I have to rename all the "isACalledActivity" activities manually when changing the 'mother' activity's name
?

Thanks, Ian. But that book doesn't seem to address BPMN (?)
