Abstract:
The attributes of quality are that it is complex taxonomy, it cannot be weighted or measured but can be felt, discussed and judged. Early assessment and verification of functional attributes (requirements) are supported well by renowned standards (methodologies) while the non functional attributes (requirements) are not. Agile software development methodologies are of high repute as the most popular and effective approaches to the development of software systems. For early quality aspects (attributes) in order to bring quality in our design and hence development process, it is very important to consider non-functional requirements/ quality attributes (metrics). A comprehensive work is also being done to propose and validate different quality models which could make sure the quality of software products being developed, which will be though available in detail in the literature review section. As highlighted thoroughly in literature review in this thesis, a generic and standard quality metrics model is missing in this for the agile software practices in all, which off course is further needed to make sure that the agile product being developed, will surely accomplish quality characteristics as decided by the stakeholders as well as the mentioned quality standard they are addressing. Here in this work we will propose and also later validate a quality metrics model through simulation and also we will do the analysis through SPSS, that is expected to fulfill the desired quality attributes exist in early requirements and that will also ensure that the quality of item being produced meet the described criteria via different case studies.
