HOW DOES A VMODEL MODEL EXPLAIN A CHANGE?

Every Vmodel model should explain at least one change. The change or changes you are explaining are in your model target.

All changes start at processes. Processes are connected to parameters using increases or decreases arrows.

When you make a Vmodel model, you talk about how processes change the parameters of the basic objects in your model. For example, the process growing changes the height of a plant. Use increases or decreases arrows to show this.

Changes can get passed along with influences arrows.

Sometimes, when one thing goes up, another thing that is related to it goes up too. For example, the taller the plant gets, the longer its shadow is. Or when one thing goes up, another thing goes down. For example, when the shadow gets longer, less area beneath the plant gets direct sunlight. You show these relationships using the influences and opposite influences arrows.

Notice that they don't cause changes, they just pass them along. The only way to get one to change is to use a process and an increases or a decreases arrow. All changes in Vmodel models start at processes!
