Hi Kumar,

Why do you think that a class diagram is not well suited for a domain model?  Do you have examples of the types of scenarios?

Hi Kumar,

A business entity model is a great asset to any project and, I would argue, it should be created as soon as possible.  Otherwise you run the risk of ambiguous requirements.  Remember that all requirements refer to "things" and "nouns" of the business and these things (business entities) need to be well defined.

Now - if you starting from scratch you will have to update the domain model many times before it becomes stable.  One option you have is to begin with a simple dictionary of business terms and describe them using words.  Once the dictionary becomes stable, begin to create your business entity model.
