Re: Moving to Agile 

Hi Tony,

In my response I didn't mean to imply that for larger scale projects use cases are the best way to model the "AS-IS" of an organization. 

If I was forced to pick only one tool I would choose a process flow diagram, probably using BPMN (Business Process Modeling Notation) to model it.  Nothing better to model business processes than a business process diagram.

If I was allowed to use two tools then I would definitely add the Business Entity Model because before even talking about how data flows within a system I would want to define the actual data to ensure that everybody knows what we are talking about.

Then I would create data flow diagrams which shows how data (as defined by the Business Entity Model) flows among processes.  I agree with you that an ERD would not be needed at this point - thanks for correct me on this one.

It's hard to fault your logic.  (I reckon context diagrams and entity diagrams are excellent tools also.)

But it seems to me that the failure you cite isn't in the modelling tools - it was in the people. Your thoughts?

Re: Moving to Agile 

Craig:

I am personally very familiar with one of the engineering managers who tried to use a Method-H-like approach to cature the as-is (of how this large this large software\electrical engineering company develops software).   This guy is leading a charge to move the developers away from ad-hoc requirements specification to more formal requirements documentation. Very few others within this company have the proper focus to successfully use any  formal as-is modeling technique.   And yet I can not use his documentation in my task of larger scale integration.   It is just to incomplete, nebulous, and wrong. 

It is not his fault.   I do not believe it is not humanly possible to come up with an integrated understanding of the inputs and outputs for a large series of interacting functions by basically looking at inputs and outputs of single functions in isolation.

Is Agile a reason to avoid documentation? I bet this question shows up again and again while working with product requirements. On one side, we have got long specifications, complicated diagrams, mystical technical design, too many prototypes and pretty obvious for engineers user guides (do we really need so much?). On the other side, can we actual...
The cloud-native application development has helped enterprises all around the globe reduce time-to-market, enhance performance, and develop agility and flexibility. Several enterprises are achieving these results by migrating their systems or traditional monolithic applications to the cloud. But to gain from the real benefits of cloud technology, ...
So you’ve found the perfect time and place to study and you’re ready to finally get some work done. You’ve pulled out your laptop, your textbook, and your notes, and four different highlighters. After five minutes of reading your textbook, you start zoning out and thinking about puppies. Then, you go on Tumblr and look at cut...
