The Best Free UML tool 2022 for Agile Development

UML in the Agile Era: Why It Still Makes Sense?

It depends on the size and complexity of the target system:

To architect a dog house can be done by one person. It involves a simple process, performed with basic tools such as nails, hammer, saw, tape etc. In few hours you end with a house for dog and can do with no one else’s help. Modeling effort is minimal or sometimes unnecessary.

If you want to build a house for your family with same things, is it possible? It requires detailed planning, some sketches etc. Of Course, architecting a house is best achieved by a team. It requires detailed modelling, well-defined processes and powerful tools.

What about a high rise building? Modeling is no doubt a critical part of any construction project!

And software development? Grady Booch said:

„Modeling is a central part of all the activities that lead up to the deployment of good software. We build models to communicate the desired structure and behavior of our system. We build models to visualize and control the system’s architecture. We build models to better understand the system we are building, often exposing opportunities for simplification and reuse. And we build models to manage risk.”
