Richard,
You are very specific with traceability model: UseCase-> UseCaseStep->Decision->BusinessRule->Facts. I think that different interpretations are possible and valid, including one from my previous message: Use Case <--> Business Rule <--> Business Object Model (with an addition of direct connection between Use Case and Business Object Model). Could you, please, share some thoughts on how to supplement UML model with business rules approach within Rational (or any other) tool set. I do believe that the less amount of different tools used - the better and am very skeptical regarding "bridges" that integrate tools from different vendors together. Thank you David -----Original Message----- From: Richard Howlett [mailto:[EMAIL PROTECTED]] Sent: Thursday, August 15, 2002 4:17 PM To: [EMAIL PROTECTED] Subject: Re: (ROSE) Business Modeling with Rational Rose Hi David, The traceability is more like this: UseCase-> UseCaseStep->Decision->BusinessRule->Facts During the course of running through a use case scenario, business decisions need to be made. Business leaders/decision makers have to decide on how the business will conduct itself when they arrive at a particular step in a use case. They need to answer the question: 'What is permissible and what should be constrained here?' Since it takes too long to describe what is permitted, only the constraints are recorded. These are business rules and ensure that the business remains in a planned and consistent state. However care must be taken in making these rules formal enough to be automated. For example, without a consistent use of terms, they are of limited value. An up-to-date fact model adds rigor by ensuring all rules are expressed using common and consistent terminology. It can be represented as a class diagram linked appropriately to ReqPro to manage the text. <<..would it be reasonable to use the same tool to manage UML model and business rules (like ReqPro-Rose)>> Well ReqPro and Rose are needed in any case for business modeling - regardless if the business rules approach is adopted. If the approach is adopted, many of its advantages can be had with a properly configured RUP Development Case. As well, you can integrate your Rational Suite / UML models with a business rules repository using a product such as Versata's Rational Rose Design Adapter. http://www.versata.com/products/inSuite/rationalrose.designadapter.html Regards, -Richard ----- Original Message ----- From: "Lyalin, David S." <[EMAIL PROTECTED]> To: "'Richard Howlett'" <[EMAIL PROTECTED]>; <[EMAIL PROTECTED]> Sent: Thursday, August 15, 2002 1:59 PM Subject: RE: (ROSE) Business Modeling with Rational Rose > Richard, > > I think that your scheme (UC-BR-BOM) is reasonable. > Business rules has to be cross-referenced with use-cases and also have to be > related to object model. > It would be reasonable to use the same tool to manage UML model and business > rules (like ReqPro-Rose). > Would you agree? > > David > > > -----Original Message----- > From: Richard Howlett [mailto:[EMAIL PROTECTED]] > Sent: Thursday, August 15, 2002 12:33 PM > To: [EMAIL PROTECTED] > Subject: Re: (ROSE) Business Modeling with Rational Rose > > > > Hi David, > > <<But I would doubt that BRs have to be managed separately, outside of the > UML model>> > What makes you doubt the need to manage business rules separately from UML > models?
