I partially agree with arpit mediratta point...but i think everytime a small change which needs to be implemented you need not re-model the whole business process again.

Proper impact analysis should be done and all the impacted areas should be identified well in advance to remodel only that portion which is getting impacted.

RE: Business Requirements Modeling

When the application environment is complex and multidimensional and when many people are directly involved in using the system then we should use business modeling.
Example- We do not need busienss modeling if we are adding another feature in an existing telecom system but if we are making a new order entry system then we should use business modeling to take good advantage to support problem analysis

RE: Business Requirements Modeling

I agree with the above answer but the Example been given is not absolutely correct.

Any time if you are adding some new module/application you need to revise the Modeling Structure.

WHY TO REVISE:

Now this is an important question why to revise everytime when you add something new in to existing application.

See a very basic example is lets suppose we have Requirment Management Tool like RequisitePro.... if we have traceability between/among the requirements and we add new requiremnt then immediately it shows ERROR.

Why so? because it is afraid of that new requirement may change or conflict with any other requirement of the system.

Same here if we don't add the new element in MODELING structure no matters whatever modeling technique one is using it might be Use Case diagram flow activity or any diagram it may get stuck anywhere.

PURPOSE of MODELING-

1. Modeling is not so much used by BA but used extensively by Technical Programming Manager.

If any new element is not been added into the Modeling how he will come to know that a new element has entered into the PROCESS.

2. Lets suppose BA is onsite for some time and new person or BA is overlooking the same process. Who will let him know that process has been changed due to some element.

So anytime if a single requirement/element is been adding/changing/deleting revise into the MODELING.

Thanks and Regards

RE: Business Requirements Modeling

BA should use modelling only when the underlying business problem is very complex and cannot be explained in plain natural language.

RE: Business Requirements Modeling

Each changes need mention in the modeling which is already developed. Thus covering the change no matter what level of change it is. This will especially help in requirement tracibility matrix
