A Tool For Feature-Requirement Traceability Using Requirement Canvas and Encapsulation

System traceability from requirements to implementation is desirable, often mandatory, for complex and safety-critical system development. However, maintaining traceability documentation can be extremely taxing and tedious through iterative and incremental development life cycles. The problem is further exacerbated when product variability is introduced in the system development. Feature modelling and product line engineering are becoming increasingly common in safety-critical domains such as the automotive domain when manufacturers must consider maintaining documentation for multiple variations of a single vehicle. This problem is made even more complex by the yearly iterations they have on their vehicles. Thus, we introduce CyclicL, a tool for developing, managing, and modelling feature-requirement traceability through iterative and incremental development strategies. CyclicL is designed to facilitate traceability between features and requirements through various product iterations, and multiple incremental feature and requirement changes.
