Their ability to effectively communicate project status and resolve issues and conflicts among stakeholders increases the likelihood of the project's success. SEs with broad knowledge of the enterprise in which requirements are being developed (whether for a system, service, or the enterprise) adds value and may be able to identify cost-effective solutions (e.g., process changes). Collect data and documents that provide context for the project.
Functional requirements are associated with the capability to directly support the users' accomplishment of their mission/tasks (features, components, etc.).Performance/functional requirements are those that are typically implicit and technical in nature that emerge as system requirements to satisfy non-specific needs (e.g., quality of service, availability, timeliness, and accuracy).Models using SDLC are waterfall, spiral, and agile.The model selected depends on factors such as the project's size, complexity, aims, and objectives; the degree to which requirements are well understood and articulated up front; the stability of the environment in which the system will function; and, most important, the customer’s needs, availability during the project, and risk tolerance.However, it increases the chances that something may happen that will cause you to miss one.
For example: The fact that you and your organization haven’t undertaken projects similar to the present one is a risk factor.
Requirements cover various aspects of a capability or system—user needs, behavioral, quality, implementation, etc.
Given these, SEs will analyze, transform, and integrate users' needs into system requirements.
Each step within the requirements sequence is completed before moving on to the next step.
Activities may be added, modified, deleted, and their sequences changed, depending on the scope and type of project or task.
Generally, subtasks within a larger project focus on fewer activities and may have different stakeholders and finer grained criteria for success than the project itself.
