There are various schools of thought about how to define terms, some arising from professional terminologists and academia. But those approaches are often relatively arcane and not well-suited to everyday business practice.

Definitions with subtle IT or ‘data’ bias are an anathema to effective communication with business partners. Good business definitions are oriented to what words mean when used by real business people talking directly about real business things.

Business Data Diagrams are one of those MUST HAVE models for any product that is dealing with data. The exercise of creating the model itself creates a powerful, shared understanding of the underlying data constructs as users understand it. Instrumental in helping to identify additional, more detailed models that might be needed, the BDD can also help you get to a complete set of user stories around users interacting with the data following the create, use, edit, delete, move and copy actions.

In other words, a security model that a security analyst can build access profiles with the appropriate privileges.  This article provides the business analyst a method for documenting a security model in the BRD based on information extracted from Use Case and Class models

Today’s letter is “C” – for Class Diagrams. Business Analysts use Class Diagrams to help them discover ‘structural’ business rules and to document them in a visual form that is readily understood by developers.  What is a structural rule?

While most business analyst roles don't explicitly require static modeling expertise, developing a better understanding of static modeling concepts can be a measurable forward step for business analysts seeking to develop new competencies. Such skills can be useful in many aspects of the BA work, from obtaining a better understanding of stakeholders' information needs, to documenting those needs in unambiguous ways and communicating them more effectively to the technical team.

“Where does UML fit?” is a common question among new (and not so new!) business analysts. We all know that the M stands for modelling but beyond this, perceptions start to differ. In its current form (V2.0) UML consists of 13 diagram types all of which provide a different view of a system.

As a software architect and developer I’ve used Enterprise Architect (EA) from Sparx Systems (www.sparxsystems.com) for a number of years. In that time I’ve spent considerable time and energy trying to get our business analysts to do the same. While I’ve had some success I must admit it’s been an uphill battle. I suspect this is partly because EA is often seen as a technical person’s tool. And that’s not altogether surprising.

  • Enterprise Architect – the name itself is completely misleading. EA is not only for people with the title ‘Enterprise Architect’. It’s for the entire project team, from BA’s to Testers and even for Clients.
  • User Interface – for developers the user interface of EA is extremely familiar and intuitive. It looks like a lot of the tools they use already. For non-technical users more familiar with tools like Microsoft Office it is somewhat more intimidating.

So, if you’re a Business Analyst looking for a tool that can help you do your job more effectively then read on.
