There are three levels of requirements:
- business requirements
- user requirements
- functional requirements.
They are collected from different sources at different stages of the project, have different goals and an audience and must be documented in different ways. Business requirements should not cancel any significant user requirements; in addition, it is necessary to trace how all functional requirements originate, and based on which user requirements. Also, non-functional requirements should be also elicited, for example, such as the expected quality and productivity. Independent verification and validation services are quite indispensable for achieving all testing objectives.
Defining the method for formulating requirements. Document the stages of discovering, analyzing, determining and verifying the requirements. The availability of manuals for the implementation of key operations can enable analysts to perform their work in a qualitative and coordinated manner. In addition, it will be easier for you to set tasks for creating requirements and schedules, and also to think over the necessary resources. Web testing service deals with detecting issues that cause web app to behave incorrectly.
Define project scope and vision. The vision and scope document contains the business requirements for the product. The description of project vision will allow all interested parties to broadly understand the purpose of the product. The scope of the project determines what should be implemented in this version, and what – in the next one. Scope and vision document is a good basis for evaluating the assumed requirements; the product vision should remain relatively unchangeable from version to version, but for each release, it is necessary to develop a separate scope and vision document.
Identify the classes of users and their characteristics. In order not lose sight of the needs of individual users, divide them into groups. For example, classify them by the frequency of the software app usage, the functions usage, the level of privileges and skills. Describe their responsibilities, location and personal characteristics that can affect the architecture of the product. Mobile app testing service is delivered to find out whether a particular mobile application works as desired.
