olemus
ISO/IEC 25010:
toote võime asendada teist ettemääratud toodet samal otstarbel samas keskkonnas
(i) tarkvaratoote ajakohastamisel on ta asendatavus kasutajale oluline
(ii) asendatavus võib hõlmata installitavuse ja sobitatavuse atribuute; mõiste on võetud eraldi alamkarakteristikuna kasutusele ta tähtsuse tõttu
(iii) asendatavus vähendab lukustumise riske, nii et senise tarkvara asemel saab kasutada muid tarkvaratooteid, näiteks standardseid failivorminguid kasutades
= capability of a product to replace another specified product for the same purpose in the same environment
Note 1. The replaceability of a new version of a software product is important to the user when upgrading.
Note 2. 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 3. Replaceability reduces lock-in risks, so that other software products can be used in place of the present one, for example by the use of standardized file formats.
