Controllability - Software and hardware states can be controlled by test engineers and the Software modules can be tested independently
Observability - Check for the object or System states and all other factors affecting the output.
Availability - Check if Source code is accessible as product evolves in stages.
Simplicity - Check if the design is consistent. Check for functional simplicity, structural simplicity and code simplicity.
Stability - Check if the Changes to the software are infrequent and changes are controlled and communicated.
