The Atego Requirements Perspective

Requirements engineering and management are key to effective systems engineering. The Atego Requirements Perspective promotes a model-based solution that can be used with any modeling notation and any toolset.

• Tool-independent and modeling notation-independent approach to model-based requirements engineering
• Scalable in terms of rigor, from non-critical to mission-critical systems
• Scalable in terms of the size of the project or system
• Compatible with major standards including ISO 15288, DO178b,etc
• Can be used as part of a larger model-based systems engineering process
• Supported by complementary deployment tool suite
• Full implementation tool support
• High quality training and consultancy services

It is widely acknowledged that effective requirements engineering and management are essential for any successful systems engineering endeavour. The traditional approach to requirements engineering is to define text-based requirements that are then used as basis for the systems development, systems validation and management. Although a text-based view of the requirements of the system is very important, it is only one of several views that are required. Before any text requirement can be understood, it is essential that it is given meaning by putting it into context, in the form of a use case. It is these well understood and defined use cases that, supported by the text descriptions, form the basis of the system development, validation and management.

When considering mission-critical systems, it is essential that this approach is formalized in terms of the framework that describes the necessary views and the process that defines how these views may be created.

Any approach must be scalable both in terms of the size and the rigor of the project. The approach should apply equally well to small non-critical projects lasting just a few days or weeks, as well as large or mission-critical projects lasting many years. The approach should also be flexible, in that each view must be able to be realized using any number of techniques, tools or notations to suit the existing needs of your organization.

The Atego Requirements Perspective defines an approach in terms of a framework and set of processes that meet all of these needs.

The Atego Requirements Perspective is a defined approach to model-based requirements engineering with a full set of supporting tools and services.
