SystemWeaver build on one source of information, i.e., there should be no redundant representation of information. An example of this is the integration of requirements and test solutions in SystemWeaver. Below is a simplified illustration of the requirements (red) and test (green) solutions in SystemWeaver. The integration between the disciplines is handled by relating test specifications and test cases to existing specifications and requirements in the requirements solutions. This means that when a requirements engineer has entered requirements, these are the exact requirements used when creating the test specification. There is thus no duplication of data that could become inconsistent.
This property of seamless integration is inherent to all solutions built on top of SystemWeaver since there is one single source of information. This means that there is no need for unnecessary tool integrations to integrate different disciplines. Avoiding redundant representation of data also limits the risk that data becomes inconsistent or incorrect.
