Time-Lag
Many systems have processes with time-lag in their behaviour. Changes to systems’ behaviour do not occur immediately when a change to the inputs or transformation process is made. Changes can take significant amount of time to take effect, therefore can be difficult to predict system behaviour. Unintended changes might not become apparent for significant…

Non-Linearity
Many systems display non-linear behaviour i.e. their outputs are not directly proportional to their inputs. Non-linear systems do not satisfy superposition principal, or superposition property. For all linear systems, net response at given place and time caused by two or more stimuli is sum of responses which would have been caused by stimuli individually. If input A…
