In the early phases of system development, the requirements and initial designs are usually imprecise and incomplete and important architectural decisions are taken. As unclear or suboptimal decisions may be time-consuming to correct later on, we advocate the use of early system validation. The current way of working of physical prototyping is based on documents. Nowadays this is changing towards executable modelling for analysis. We create executable models that abstract from as many details as possible, and combine them with domain visualizations (analysis) to bridge the gap between system design and software design. 

POOSL is a modeling tool that supports lightweight simulation. POOSL stands for Parallel Object-Oriented Specification Language. We use POOSL to analyze aspects such as functional requirements, architectural decomposition, component interaction, and performance indicators.  The overall goal is to be able to get early feedback on system requirements and design using simulations in order to do better analysis and have a quicker feedback loop between architects who analyze system behavior.
