2.4 Programming For Reliability

	Critical programming errors are specific architectural and/or coding bad practices that result in the highest,
	immediate or long term, business disruption risk.

Critical programming errors can also be classified, for example:

Avoid software patterns that will lead to unexpected behavior (Uninitialized variable, null pointers, etc.)

		Methods, procedures and functions doing Insert, Update, Delete, Create Table or Select must include error
		management.

		Multi-thread functions should be made thread safe, for instance servlets or struts action classes must not
		have instance/non-final static fields.
