-Software should deliver the required functionality and performance to the user and should be maintainable, dependable and acceptable. -Maintainability -Software must evolve to meet changing need. -Dependability -Software must trustworthy -Efficiency -Software should not make wasteful use of system resources. -Acceptability -Software must accepted by the users for which it was designed. This means it must be understandable, usable and compatible with other systems.
Because maintenance is the most expensive part of the life cycle

As per my understanding the Suitability Criteria can be defined as Accessability of application, Usability, Maintainability and so on.

maintainability
essential and important attributes that every software product must contain are the following: 1) maintainability 2)dependiabilty 3) efficiency 4) usabilty
Maintainability can be loosely referred to as the ease with which a system or product can be kept in working order, including the ease of making modifications, repairs, or updates. It encompasses factors such as the clarity of documentation, the design of components, and the availability of tools and resources. High maintainability often leads to reduced downtime and lower long-term costs. In software, it reflects how easily code can be understood, modified, and extended.
Security, Reliability, Usability, Robustness, Maintainability, Correctness, Speed etc You can look at Software Dependability, Quality, Other keywords like being User-friendly, you can add Software + "feature" like Software Security and search for more explanations.
One can effectively measure software quality by using metrics such as code complexity, code coverage, defect density, and user satisfaction. These metrics help assess the reliability, maintainability, and usability of the software, providing insights into its overall quality.
important attributes are maintainability, dependability, performance and usability. Other attributes that may be significant could be reusability (can it be reused in other applications), distributability (can it be distributed over a network of processors), portability (can it operate on multiple platforms) and inter-operability (can it work with a wide range of other software systems). Decompositions of the 4 key attributes e.g. dependability decomposes to security, safety, availability, etc.
Strong cohesion ensures that components within a software system are closely related in functionality, making them easier to understand, test, and modify. Weak coupling minimizes dependencies between these components, allowing changes to be made in one part of the system without significantly impacting others. Together, these principles enhance maintainability by simplifying the process of updating and debugging the system, as well as facilitating easier integration of new features or components. This leads to a more robust and adaptable software architecture.
