One or more of these factors may be important on any given occasion. Some leave no room for selection: regulatory or contractual requirements leave the tester with no choice. Test objectives, where they relate to exit criteria such as test coverage, may also lead to mandatory techniques. Where documentation is not available, or where time and budget are limited, the use of experience based techniques may be favored. All others provide pointers within a broad framework: level and type of risk will push the tester towards a particular approach, where high risk is a good reason for using systematic techniques; knowledge of testers, especially where this is limited, may narrow down the available choices; the type of system and the development life cycle will encourage testers to lean in one direction or another depending on their own particular experience. There are few clear-cut cases, and the exercise of sound judgement in selecting appropriate techniques is a mark of a good test manager or team leader.
