Why Use Case Modeling

One of the most challenging things to do when developing software applications is to build the right thing, especially for those complex and large-scale systems. Most of the projects failure ending up with expensive rework, delayed releases, or even abandonment are due to the poorly conducted requirement works in the early stage. Requirement specifications should always focus on the users of the system, not the system itself, thus the real system needs are brought to light early on. Use case driven approach encourage designers to envision outcomes before attempting to specify outcomes, and thereby they help to make requirements more proactive in system development.

Since a use case consists mainly of narrative text, it is easily understandable by all stakeholders including customers, end users and managers, not just developers and testers. It builds a shared vision of the targeted systems under developed, by bridging the gap between the people who has the best knowledge of what goals needed to be achieved and the people who understand how to build a solution; not only promoting a sense of ownership from targeted users, but also eliminating surprises when the system is delivered.

Visual Paradigm for UML (VP-UML) provide an intuitive all-in-one development platform which come with the automated Use Case Modeling Toolset as an integral component of the product, enabling use case specification to be further refined into other analysis and design deliverables. Our outstanding automated Use Case Modeling process will help your team to accurately transform systems requirement into quality software solutions, with minimum risk and maximum ROI. We design and develop products that remove complexity, improve productivity, and compress your software development time frames.

Do wait! Download Visual Paradigm for UML to enjoy the following benefits regardless of which role you are playing in the development team:

• Easier and earlier user validation.
• Use cases are useful for scoping. Use cases make it easy to take a staged delivery approach to projects; they can be relatively easily added and removed from a software project as priorities change.
• Use cases can also serve as the basis for the estimating, scheduling, and validating effort and they are reusable within a project. The use case can evolve at each iteration from a method of capturing requirements, to development guidelines to programmers, to a test case and finally into user documentation.
• Use case modeling provide basic groundwork for the requirements document, user manual and test cases. Test case scenarios or Test Scenarios can be directly derived from use cases.
• Use cases are concerned with the interactions between the user and the system. They make it possible for user interface designers to become involved in the development process either before or in parallel with software developers.
• Better traceability through the system development process.
• Uniquely identified use cases can be traced back to business requirements or stakeholder needs.
• Use case partitioning can be used to organize and structure the requirements model, permitting common behavior to be factored out for system reuse.
• Use case alternative paths capture additional behavior that can improve system robustness.
• Good way to start identifying objects from scenarios.
• Helps technical writers in structuring the overall work on the user manuals at an early stage.
