各位蒲友:关于实验室仪器软件升级本人原认为增加功能归类于变更,未增加功能归类于维护,不确定故查了些资料,查完资料(尤其下面帖子内容)后感觉更纠结了。到底怎么分类麻烦给位给指正下,谢谢
以下内容为其他蒲友帖子内复制,
关于软件和硬件维护的差别:
The operational maintenance of hardware and software are different because their failure/error mechanisms are different. 因为它们的故障/错误的机制不一样,所以对于硬件和软件的维护也不同。Hardware maintenance typically includes preventive hardware maintenance actions, component replacement, and corrective changes. Software maintenance includes corrective, perfective, and adaptive maintenance but does not include preventive maintenance actions or software component replacement.硬件的维护通常包括预防性维护措施、部件更换和改正变更。软件的维护包括改正性的、完善性和适应性的维护,但是不包括预防性维护或者部件的替换。
Changes made to correct errors and faults in the software are corrective maintenance. Changes made to the software to improve the performance, maintainability, or other attributes of the software system are perfective maintenance. Software changes to make the software system usable in a changed environment are adaptive maintenance.改正错误和故障的变更时改正性维护,提高性能可维护性或者软件系统的其它属性是完善性维护,在变化的环境中改变系统以适应,是适应性维护。
