“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 better understand the system we are building, often exposing opportunities for simplification and reuse.
What is the need of modeling?
Models help us to visualize a system as it is or as we want it to be. Models permit us to specify the structure or behavior of a system. Models gives us a template that guides us in constructing a system. Models document the decisions we have made.5 aug. 2013
Also, What is the need for modeling in Ooad?
The Unified Modeling Language (UML) is a graphical language for OOAD that gives a standard way to write a software system’s blueprint. It helps to visualize, specify, construct, and document the artifacts of an object-oriented system. It is used to depict the structures and the relationships in a complex system.
Regarding this, Why is using UML for modeling important? Importance of UML Diagram UML diagrams can be used as a way to visualize a project before it takes place or as documentation for a project afterward. But the overall goal of UML diagrams is to allow teams to visualize how a project is or will be working, and they can be used in any field, not just software engineering.12 sep. 2019

Why do we need to have models?
We very often need a range of models for any given problem, including simple models that can run on a human brain. The most important bits of a model are the people who create and run the model and use its output – developing the community of users and developers is as important as developing the software.
Why is it important to model to students?
Effective modelling makes you a better teacher. Models are enablers – they are there to help students see what outcomes could/should look like. It allows your students to engage and succeed and it reduces your workload because common misconceptions are addressed as or before they arise.9 apr. 2019
