Notes
EXAMPLE: The replaceability of a new version of a software product is important to the user when upgrading.
NOTE 1 Replaceability can include attributes of both installability and adaptability. The concept has been introduced as a subcharacteristic of its own because of its importance.
NOTE 2 Replaceability will reduce lock-in risk: so that other software products can be used in place of the present one, for example by the use of standardized file formats.
