Technique: Test strategy
How? Project/process risks Delay in development Insufficient resources Insufficient skills and expertise …. Product risks Business consequences due to: System failure Security failure Performance issues …. Test plan Test strategy Detect the most important defects as early as possible in a cost effective manner! TMap

Example: Techniques Checklist Maintainability: How?
Functional system architecture Has the choice of subsystems been argued? Has a general reference model been used? ... Technical system architecture Are the routine actions built into the user interface, consistent? Have check processes ('watch dogs') been applied? Is the operator able to supply status information? Data infrastructure Is the data model normalised? Development environment Is an integrated test facility available? TMap
