Given that a context diagram depicts a system, it makes sense to have our ‘System Thinking’ hat on, whereby: “An analysis model that illustrates product scope by showing the system in its environment with the external entities (people and systems) that gives to and receives from the system.” What’s in scope? Where does the work fit in? Who are the stakeholders? And so on.Ī common way to model scope is to use a context diagram, which the BABOK defines as: One of the first things I like to do when trying to understand a problem is to develop a high-level overview of the situation.
These techniques have their roots in Soft Systems Methodology (SSM), but I’ve found them to be quite useful as tools forming part of my analysis approach. Today I will be focusing on Rich Pictures and CATWOE, which are somewhat lesser known, yet simple techniques which can both add value to analysis activities. The BABOK outlines a total of thirty-four “generally accepted techniques that support the practice of business analysis”, however, in my experience there are many more techniques out there. The greater number of tools under my belt, the greater choice I have in not only planning my approach, but also in conducting my analysis activities. As a Business Analyst, I’m lucky enough to be continually learning new tools, techniques and methodologies.
