Stol and Babar have proposed a comparison framework for OSS evaluation methods. Their framework lists criteria in four categories: criteria related to the context in which the method is to be used, the user of the method, the process of the method, and the evaluation of the method (e.g., its validity and maturity stage).
QSOS defines 4 steps that are part of an iterative process: QSOS general process. 1 - Define and organise what will be assessed (common Open Source criteria and risks and technical domain specific functionalities), 2 - Assess the competing software against the criteria defined above and score these criteria individually,
Source selection criteria describes properties that are crucial for a purchaser when deciding on a supplier. Criteria can be subjective or objective. Criteria can be subjective or objective. Individual judgment can be biased, which may require balancing with objective measures.
Criteria (to build): They describe the internal view of the software, as seen by the developer. Metrics (to control): They are defined and used to provide a scale and method for measurement.

A software requirements specification (SRS) is a description of a software system to be developed.It is modeled after the business requirements specification.The software requirements specification lays out functional and non-functional requirements, and it may include a set of use cases that describe user interactions that the software must provide to the user for perfect interaction.
The decision-matrix method, also Pugh method or Pugh concept selection, invented by Stuart Pugh, [1] is a qualitative technique used to rank the multi-dimensional options of an option set. It is frequently used in engineering for making design decisions but can also be used to rank investment options, vendor options, product options or any ...
In systems engineering and software engineering, requirements analysis focuses on the tasks that determine the needs or conditions to meet the new or altered product or project, taking account of the possibly conflicting requirements of the various stakeholders, analyzing, documenting, validating, and managing software or system requirements.
