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 we all know that pictures (diagrams) are much more effective and less ambiguous than words. Remember the phrase "A picture is worth a thousand words". The question is – which type of diagram best suits our needs? In this article, written by IRM's Training Services Manager Jan Kusiak, we’ll look at using diagrams for stakeholder communications.

The short answer: "Because it requires work."
The long answer: People tend to resist gazing into the crystal ball and prefer to react to life as it passes them by. Some people believe planning in today's ever changing world is a waste of time, that you must be more "agile" and accommodate changes as they occur. As anyone who has designed and built anything of substance knows, this is utterly ridiculous. We would not have the many great skyscrapers, bridges, dams, highways, ships, planes, and other sophisticated equipment without the efforts of architects and engineers. Without such planning, our country would look essentially no different than how the pioneers first discovered the continent. Although we must certainly be flexible in our plans, and we will inevitably make some mistakes along the way, little progress would be made if we did not try to plan a course of action and control our destiny.
People often take planning for granted, that someone else will be making plans for us, such as government officials, our corporate management, or even the elders of our families. Consequently we become rather lax about looking into the future. Nor is there any encouragement by anyone to plan our affairs, such as a tax break. Whereas other countries offer incentives to save money for the future, such as Japan, America does not. Therefore, planning is a rather personal activity; we either see the virtue in doing so or we do not.

In its simplest form, a Feasibility Study represents a definition of a problem or opportunity to be studied, an analysis of the current mode of operation, a definition of requirements, an evaluation of alternatives, and an agreed upon course of action. As such, the activities for preparing a Feasibility Study are generic in nature and can be applied to any type of project, be it for systems and software development making an acquisition, or any other project.
