Following feedback, I have made the full paper on architecture state modelling available as follows:

Hi Q
I thought by keeping the abstract short, the line that explained the rest of the paper is available by signing-up - for free - would be easily seen. This not being the case Ill rethink. Drop me a PM and Ill email you a copy of the paper directly (should they be called electronic these days?)
Namaste 🙏

General Board / Architecture State Modelling
« on: July 15, 2020, 05:16:20 am »
Architecture State Modelling is the process of defining and working with different architecture states at the same time.

Thus you can hold a model of your AS-IS, the TO-BE, and all the other states between them. You can then do that all-important gap analysis and roadmapping work.

The subject has been explored in some depth (not too much) in a paper available here:

There are different ways of approaching this subject, and it would be interesting to get all contrasting and/or complimentary views on the content of this paper.

Hi Geert
Thank you ... then that is what we shall do!  :)
All the best

Hello all
Did the feature of showing alias of an object in the browser make it through to a release?
All the best

What if the server is shared with other applications?

In our case (for the initial stages at least), PCS/Prolaborate will be co-tenant with a handful of applications of a similar ilk >>> PLEASE can anyone share any experience of having to scale up, virtualise or dedicate the Prolaborate server, and what are the main things to watch for?

[I know - how long is a piece of string? It's just that other's prior experience is always a good place to start]


PCS General Board / Let's discuss Prolaborate best practice
« on: July 08, 2019, 09:01:15 pm »
The idea here is to start a discussion about how to make best use of the Prolaborate features. We're just starting out with a Proof of Concept ourselves, so I don't expect I'm bringing any new insights at this point. But I do really love the concept and the user interface is stunning. With a considerable amount of flexibility in how to use the product, it seems wise to share best practice. My initial observations and questions for any trailblazers out there are:

  • Best way to hold discussions in the context of a review? It looks as though review comments are the same as discussion comments, but tagged against a review(?). But were not sure how this helps us navigate on a per review basis probably because were not taking the right approach?
  • Were unclear how to freeze the content of a section so that during a review period there are no shifting sands: it appears as though edits can take place within Prolaborate after someone has commented on the content and this could rather invalidate a review comment. I suspect the answer to this is to enable user security on the database and lock the content during the review period? Probably you'd want to do this anyway to stop EA users directly altering the content under review.
  • How a moderator can flow the review comments into the model content?


General Board / Re: Maintaining mapping from current to future state
« on: July 10, 2018, 04:11:29 pm »
Hello Kurt

Let's recap: we want to be able to model different architecture states and manage the steps we need to take to get from one to another?

Nearly a decade on ... how did you get on with this? Did you find a workable solution? Did the problem go away? Did you give up? I'd be keen to learn of your journey. What would you say in relation to:

  • The extent to which the Gap Analysis matrix helps? I've found it useful, but is only part of the puzzle.
  • I really like what the BEASI plug-in achieves - it is a very graphical way to depict deltas between current and future. Does anyone have any independent success stories about how it scales to a complex model?
  • The Time-aware Modelling new in EA 13 is interesting: does anyone have any success stories from using that? My issue with it lies in the fact it muddles the two states as one model. In practice, with a complex transformation, maintaining separate models but being able to track the deltas between them is really important. Why? A number of reasons:

    • It can take many months to build a target architecture;
    • Meanwhile you need to keep your current architecture, well, current. It is going to change and you have to reflect this as the baseline model is the document you refer to for maintenance (right?);
    • To explore different transition options, with a complex architecture, how do you a rolled-up view of the many gaps (deltas) between them, and then go on to select the best, when the two states are muddled as one?;
    • One option in transformation is to have a period of parallel running: i.e. you keep your current IT estate supporting AS-IS processes, whilst you run up the new estate and support TO-BE processes;

I'm coming to the view that there is no one size fits all approach in this space. For simple scenario, a simple Gap Matrix helps enough. For richer scenarios, the graphical power of BEASI gives real insight and helps with stakeholder engagement. When it comes to a large scale transformation of a complex architectural landscape, I think you need a system to automatically track all the deltas between several different architecture states:
  • baseline
  • chosen target
AND, if you're doing a thorough job:
  • candidate target(s) (you don't conceive of just one before deciding to spend 10s of M, do you?)
  • candidate transition state(s) (so you can think through the journey you'll take your organisation on)
  • actual transition states

This is needed because it helps a large architecture team working with a plethora of stakeholders to come to optimal options (OK, I mean risk reduced options), but also because you'll want MI on how you're doing to ensure your transformation is keeping on track.

Thoughts anyone?


Thank you Nizam
Good spotting!

General Board / Re: When is an instance not an Object?

Wow, you... actually sat down and did that.
That is laudable, or possibly certifiable. I get them confused. Either way, you deserve a long weekend.

On artifacts, I remember this discussion was up at some point and someone from Sparx said that there's a bug, which will be fixed, in how EA handles instantiation of artifacts, and that's why instances of artifacts appear to be both classifiers and instances.

I had a trawl through my mailbox but I couldn't find it. Possibly it's in a thread here on the forum.

Hi Uffe
Madness is not alone - found myself doing this last year (or was it 2016, also have memory loss). It was a necessary exercise in determining what metaclasses to base a new profile on. So there was method in the madness. I anticipate Ian is also following a similar train of thought ...........

General Board / Re: Database for default startup project is down
« on: December 12, 2017, 08:02:16 pm »
When a new key is created in the registry, a default value name/data is added to it automatically which is usually unused.
...worked for me. How would that be?
Some[thing | one] has fixed the actual problem for you elsewhere.
I wish!
As you couldn't even open an .eap locally by double clicking, your problem was not solely because of the database server being down. It could be your network that had issues and EA couldn't access the license details from the key store.
Fixed node license in my case due to laptop
OTOH, Sparx has previously confirmed an issue where if the default project is not accessible, EA cannot be launched. However, in this case EA could be launched by double clicking on an .eap
That's what I was doing - and it wouldn't open.
But the main thing is - thank you for your help with the right key.
In any case I've disabled default project. I'm not that lazy.

Thank you VKN for the registry key correction.
Succinct and helpful. Makes more sense too.
Curiously though, the key I altered worked for me. How would that be?
All the best

Done, pointing at the discussion thread  :D

Thanks Qwerty - so it's in the registry under
HKEY_CURRENT_USER\Software\Sparx Systems\EA400\EA\Recent File List,
and is the 'default value' key

General Board / Database for default startup project is down
« on: December 10, 2017, 09:06:57 pm »

Because the SQL database server that hosts the default startup project is down, EA can not open the default project and will not even start. I can't even work on a local model by double-clicking it. The process is stuck.

Does anybody know where the configuration file is to change the default start-up project?

Thanks in advance
