Traceability is a critically important aspect of software development that is often required by various professional standards and government agencies. Yet, current approaches do not adequately address end-toend traceability. Consequently, many industry projects become entangled in process overhead and fail to derive much benefit from current traceability solutions. This paper presents a succes...

Traceability codes are combinatorial objects introduced by Chor, Fiat and Naor in 1994 to be used to trace the origin of digital content in traitor tracing schemes. Let F be an alphabet set of size q and n be a positive integer. A t-traceability code is a code C ⊆ Fn which can be used to catch at least one colluder from a collusion of at most t traitors. It has been shown that t-traceability co...

Our earlier research indicated the feasibility of the PREDIQT method for model-based prediction of impacts of architectural design changes, on the different quality characteristics of a system. The PREDIQT method develops and makes use of a multi-layer model structure, called prediction models. Usefulness of the prediction models requires a structured documentation of both the relations between...

If we are to be successful in the development of the next generation of agent oriented systems we must deal with the critical issue of requirements traceability. Failure to do so will imply in higher costs and longer corrective and adaptable maintenance. Unfortunately most agent-oriented methodologies are not addressing this issue. Requirement traceability is intended to ensure continued alignm...

[Context and motivation] Safety evidence plays an important role in gaining confidence in the safe operation of a system in a given context. For a large system, it is necessary to provide information about thousands of artefacts that might be used as evidence and about the relationships among themselves and also with other safety assurance assets. [Question/problem] Past research has only addre...

Requirements traceability is defined as “the ability to describe and follow the life of a requirement, in both a forwards and backwards direction”.[1] Once a requirement is documented, traces for every component of the software system that are impacted by the requirement, are constructed and maintained. During later discussions regarding bug fixes and proposed system enhancements, these traces ...

In requirement engineering, researchers have proposed various tractability recovery approaches. To the best of our knowledge, all traceability recovery approaches have low precision and recall. Our main claim in this chapter is that there exist factors that impact the traceability approaches’ inputs, in particular source document, target document, and experts’ opinion, that cause low precision ...

In the paper “New Results on Frame-Proof Codes and Traceability Schemes” by Reihaneh Safavi-Naini and Yejing Wang [IEEE Trans. Inform. Theory, vol. 47, no. 7, pp. 3029– 3033, Nov. 2001], there are lower bounds for the maximal number of codewords in binary frame-proof codes and decoders in traceability schemes. There are also existence proofs using a construction of binary frame-proof codes and ...

Food safety is a widely concerned problem in current world. Traceability technology is an effective measure to solve the problem. This paper describes the study of the traceability of grain and oil products. Include the study contents, and a system we developed for traceability of grain and oil products, and the demonstration of the study. The system we developed was used in Luhua group and som...

Software artefact traceability is widely recognised as an important factor for the effective development and maintenance of a software system. Unfortunately, the lack of automatic or semi-automatic supports makes the task of maintaining links among software artefacts a tedious and time consuming one. For this reason, often traceability information becomes out of date or it is completely absent ...
