Why Do Software Engineers use models?
The idea of visually modeling software, and the tools to support this endeavor, have beenaround for a few years. However, many developers and project managers may not understandwhy this is important to software development. Sometimes the project managers understandthe rationale for modeling tools, but they must convince upper management, who ultimatelymust give authority for a relatively large software purchase.This white paper gives an overview of the justification for modeling, as well as a rationale forthe use of a modeling tool. It also describes the minimum feature set that any modeling toolshould have.Why model?"If you were supposed to understand it, we wouldn't call it code." -- from a Federal Expresspromotion, reported by IS Survivalist Matthew PersicoSome development managers wonder why modeling is important at all. After all, the codeshould speak for itself. In essence, the code is the model. Why add an extra layer ofabstraction that we have to maintain as the project progresses? The reason is that there are anumber of clear benefits that models provide a development organization. They are enhancedcommunication, better planning, reduced risk, and reduced costs.Enhance communicationThe beginning of the legal description for my plot of land is shown in Figure 1. If you were asurveyor, you would be able to take the full description and draw my lot, and point to a mapand show me exactly where my house is. To a surveyor or lawyer, this is the "code" thatdescribes the land that I own. While this is an exact description of my property, this is not anatural way of viewing the world. Given the description above, an experienced surveyormight have a general idea of what my lot looks like, what direction it faces, and so on. HeSoftware Modeling Introduction - Why do I need a modeling tool?4could put a picture in his mind for this plot of land. However, even this is not a natural thingfor any person, no matter how mathematically inclined they might be. Anyone will want tosee a drawing of the land. As you can see, the lot is relatively plain - roughly rectangular inshape, nothing extraordinary.
