Selected:Stock and Flow Diagram System Dynamics Simulation LASR (Lightweight Approach for Software Reviews)

Criterion	Systems Thinking Stock and Flow Diagram	Systems Thinking System Dynamics Simulation	Architecture LASR (Lightweight Approach for Software Reviews)
Purposedifferent	A Stock and Flow Diagram shows how stocks, inflows, and outflows shape a system over time. It is especially suited when growth, delays, or capacity limits determine the dynamics.	System Dynamics Simulation makes assumptions about time, delay, and feedback testable through experiments. It draws relationships, patterns, and feedback loops. The result is captured as a simulation model and scenario reports.	LASR helps development teams identify where their software falls short of important quality goals and which improvements to consider. A small group with existing system knowledge can make an initial assessment and investigate open questions in more detail.
