General Board / Re: Lining up labels
« on: August 20, 2007, 11:09:03 am »
Select the elements you want to line up.
Right click on them, and you'll have the options.

That works for the elements, but not for the labels (at least not with Interface lollipops or data ports.)

Thanks for the reply,


General Board / Lining up labels
« on: August 20, 2007, 08:52:44 am »
Is there a way to select several elements (say three interfaces or three ports) and automatically line up the labels for the elements? I'm looking for a quick way to tidy up drawings. So far, I have to select and manually resize or move each label, which is tedious on a complex drawing.

General Board / Re: Using Subversion
« on: July 18, 2007, 01:12:04 pm »
I'm using EA with Subversion. If you remove the lock requirement for the .EAP file, my guess is that the person who commits the file second will overwrite all changes made by the person who checks in the file in before.

I have about five people working with a model through shared packages. We use MySQL and ODBC to hold the model (instead of a .EAP file, but a .EAP file will work the same way) and the packages are controlled through Subversion.

Subversion serves two purposes. One is that it provides access-control to the packages, keeping all users except one locked out. Secondly, it maintains a history of changes in each package.

I can give more insights if you have questions.

We're modeling a complex hardware/software system. We have identified the actors and many high-level use cases (we still have to detail the scenarios) and from those we are deriving functional requirements, as well as the occasional performance requirement.

As I think about it, I realize we still have to work out detailed scenarios for the use cases. I'm finding this process of using use cases as a tool to identify requirements pretty useful.

Usually stakeholder requirements are first and use cases come after. Use case are able to realize requirements.

What kind of requirements are you writing, when use cases are already done?

Thanks for your insights. My team of five is going to use it, at least for a while. I looked at other possibilities and didn't see anything compelling within my budget. We've created use cases and now we're moving into requirements.

General Board / Who uses EA for requirements management?
« on: May 18, 2007, 08:54:56 am »
Has anyone used EA to manage requirements on a project that has  several hundred requirements and several analysts? How well does the process work? I'm a fan of UML and EA, but I'm concerned that there is not strong enough support for trace matrices and data entry for it to be an advantageous tool for collecting and managing requirements (especially when some of the users won't have UML knowledge.)

BTW, we're working toward a CMMI ( level 3 in our organization.

I do like the idea of being able to relate requirements to the development phase of a project, which EA can do very well.

Thanks for any info, including lessons learned...


General Board / Re: Assemblies and Interfaces - Can they be relate
« on: July 03, 2007, 06:50:38 am »
Ok, I'll buy the explanation from bruce (given that I am Bruce (large B), this thread got me confused.) It would be nice if assemblies could be related to defined interfaces to make the overall model more consistent and robust.

At this point, I'm describing, in broad terms, how a proposed hardware/software system will interact with an existing hw/sw system. I'm identifying interfaces and the format of the information that flows through them (or, for hardware, the type of connector required.) The data format is predefined, as one half of the system already exists.

Assemblies will work for me. I had to walk through the EA documentation to figure out what to do. At first, I tried dragging lollipops onto sockets in hopes that they would interlock (that seems intuitive), but they didn't. Then I found assemblies, but discovered they don't relate to actual interfaces defined on the components. I guess there's room for improvement in EA here, but I can live with it.

Thanks for your help,

I'd appreciate your insights, including what you mean by "both shall be used in different contexts."

General Board / Assemblies and Interfaces - Can they be related?
« on: July 02, 2007, 09:29:20 am »
EA Version 6.5

I know how to create an interface and call it, say "Interface1". I can also create an exposed interface and give it the type "Interface1". I even know how to create an assembly (the neat ball/socket connector that shows how two components connect through interfaces).

What I can't figure out is how to create an assembly and give it the type "Interface1" so that it relates to an interface I defined in my model. All I know how to do is give the assembly a link name of "Interface1", which is not the same thing and does not tie the assembly to the interface I have defined.

How do I bond assemblies with interface definitions so they are tied together in the model?

General Board / Re: EA's discussion forum - adding links

OK - I figured out what I was doing wrong, and it's an easy trap to fall into.

The discussion forum can have "categories", "topics", and "posts." The three entities have different icons, but otherwise have exactly the same appearance UI appearance. One can only make links to posts, not to topics or categories. I was naively trying to link to a topic, which doesn't work. Linking to a post is simple.

I suggest not having the link region available for categories or topics if it can't be used.

That section says "Elements can be associated with the discussion forum message by dragging the element from the Project View into the linked elements section of the project discussion forum. "

Assuming the "Project View" is the same as the project browser, I've tried dragging into the linked elements section, but nothing happens. I can't figure out what I'm doing wrong.



Have you read

This describes how to create the link.

EA 7 beta 2 adds the ability to drag from a search view.

General Board / EA's discussion forum - adding links
« on: June 19, 2007, 12:45:01 pm »
I tried EA's discussion forum (control-alt-U brings it up) feature. It has a tantalizing subscreen and a help message that  states one can "link EA elements to the discussion", but I can't figure out how to do that. I've dragged, dropped, and clicked to no avail. What's the secret?

EA version 6.5, Win XP.

General Board / "Link tab" for requirements
« on: June 15, 2007, 02:24:34 pm »
When I look at properties for a use case, it has a "link" tab. I can see the link to an external requirement.

When I look at the properties for that requirement, it does not have a "link" tab and I can't find any indication that it is referenced by a use case.

Is there a way to do that?
