Drawing on a pr-developed software customization model for SaaS quality, two fundamental objectives of this stu...

Context A plethora of models are available for open-source software (OSS) usability evaluation. However, these models lack consensus between scholars as well as standard bodies on a specific set of usability evaluation criteria. Retaining irrelevant criteria and omitting essential ones will mislead the direction of the usability evaluation. Object...

Component-based software system (CBSS) must be designed and implemented not only to meet the current customers’ requirements, but also to be receptive to future changes. Therefore, most often, one or more components of the system may need to be changed. Usually, designers do not exactly know what the future state looks like. The need for change con...
