» FEATURED: Use Cases and Business Rules: Can They Work Together?
Article Rating (3300 Views) (23 Comments)
Use Cases and Business Rules: Can They Work Together? There is much written today about separating business rules from other dimensions of automated business systems. Without proper separation, they operate in enterprises without a great deal of thought given to them. Ironically, they may be the most important dimension because they represent important business thinking behind processes, use cases, fo...

Article Rating (4048 Views) (10 Comments)
From Research to Implementation: Use Case Diagrams – Usage and Benefits Some people use them. Some people don't use them. Some people create them using sophisticated tools. Some use basic drawing programs. As part of the Unified Modeling Language, Use Case diagrams are often the starting point for many software projects. However, questions about Use Case diagrams still linger in the minds of many Business Analysts...

» UML - Business Context
Article Rating (6154 Views) (2 Comments)
“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. In this article we’ll take a brief look at which of the...

» Stakeholder Communications - Pictures not Words
Article Rating (4426 Views) (5 Comments)
Many people on our Business Analysis workshop ask why we use dataflow diagrams (DFDs). Why not Use Case…or even BPMN? After all DFDs have been around for 20 years, surely the world has moved on? Well, has it? The primary purpose of a business analyst is to communicate – to stakeholders and to solution providers – and when it comes to communication...

» Enterprise Architect for Business Analysts
Article Rating (61118 Views) (7 Comments)
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 i...

Structure diagrams in general Structure diagrams show the static structure of the system being modeled. focusing on the elements of a system, irrespective of time.

» The Pros and Cons of Use Case Diagrams
Article Rating (3090 Views) (0 Comments)
In the Unified Modeling Language (UML), use cases are visually represented as ellipses. However, in spite of its popularity and size, UML has little of practical use to offer modelers beyond this simple iconic representation. Trying to capture and present requirements using just use case diagrams can often render the otherwise useful technique of u...

» "Analysis and Design" Considered Harmful
Article Rating (1396 Views) (2 Comments)
This article describes a common pitfall of thinking of analysis and design together as a single process, and highlights the need to treat analysis and design as two separate processes. The author, points out that much of the UML standard, as it is explained today, is described in terms of design artifacts rather than analysis artifacts. Author: Co...
