Whether your bank account, the customers of a restaurant, or the trees in the rainforest, the world is driven by the changes of things over time. Sysdea® makes it simple to start modeling these systems, while remaining easy to understand and show to others.

Sysdea® modeling is based upon Stocks (something that accumulates, such as money in a bank account, trees in a forest) and Flows (the forces that cause such Stocks to accumulate and deplete). With just these two concepts and supportive Variables to allow intermediate calculations, you get great expressive power.
Each time you make a change the model instantly updates, having such quick feedback allows you to rapidly build models with confidence. There's no worries about cell references and copying formulae as in a spreadsheet, and charts attached to everything allow easy at-a-glance inspection of behaviour.
