Quality Assurance Services: Benefits of Use Cases

Quality Assurance Services: Benefits of Use Cases

The advantages of use case driven analysis is that it allows you to manage complexity because it focuses on the user of the system rather than the system itself. Users will have a clearer idea of ​​what useful things the new system will do if you choose a method that focuses on the functions of the system. During the development of several Internet projects, customer representatives said that the use cases helped them to more clearly understand what features and functions should be available to visitors to their Web sites, while analysts and developers were able to understand both the business processes of business users, and the subject area. Careful study of the stages of interaction between the person and the system helps to identify ambiguities and inaccuracies in the early stages of development, and also allows you to write test cases based on use cases. Quality assurance services are meant to monitor the quality of software apps throughout their development life cycle.

It is very wasteful and painful for developers to write code that they will never be able to use. If you define the requirements in advance and include all conceivable functions in them, then you risk creating excessive requirements. The use case method allows you to identify the functional requirements that will support user tasks the way that users will perform or want to perform them. By doing so, you will prevent the emergence of “orphaned functions”, those that seemed very useful in the collection of information, but no one will use them because they are not directly related to solving operational tasks.

The application of use case method facilitates the requirement prioritization process. The highest priority is assigned to those functional requirements that are created on the basis of the highest priority use cases. It always makes sense to outsource qa to competent quality assurance specialists who will do your work for you in the most effective way. The highest priority is assigned for the following reasons:

• Use cases describe one of the main business processes invoked by the system.
• Many users often need and resort to these use cases.
• They have been requested by a privileged class of users; they provide the capabilities necessary to meet the requirements.
• Functions of other systems depend on whether such use cases are available.

Be careful and do not spend much time discussing details of use cases that will not be implemented in the coming months or years. Most likely, they will change even before the assembly work begins. Quality assurance team is waiting for you to use their professional services so that to improve your products according to customer needs.
