Why and How Your Traceability Should Evolve: Insights from an Automotive Supplier

Traceability is a key enabler of various activities in automotive software and systems engineering and required by several standards. However, most existing traceability management approaches do not consider that traceability is situated in constantly changing development contexts involving multiple stakeholders. Together with an automotive supplier, we analyzed how technology, business, and organizational factors raise the need for flexible traceability. We present how traceability can be evolved in the development lifecycle, from early elicitation of traceability needs to the implementation of mature traceability strategies. Moreover, we shed light on how traceability can be managed flexibly within an agile team and more formally when crossing team borders and organizational borders. Based on these insights, we present requirements for flexible tool solutions, supporting varying levels of data quality, change propagation, versioning, and organizational traceability.Comment: 9 pages, 3 figures, accepted in IEEE Softwar

Agrifood logistics and food traceability

Traceability systems are recordkeeping systems designed to track the flow of product and/or product attributes through the production process and throughout the supply chain from producers to consumers. The aim of this study is to review the current status of traceability systems in food companies, compare different traceablity systems applied by food companies, and analyse the sources of variation in their efficiency. A traceability system is characterized by its breadth, depth, and precision. Differences in efficiency are attributed to the costs and benefits of traceability’s implementation to these three traceabiligy characteristics. Three case studies were conducted during the period April-May 2005. All cases were large food companies, with more than 250 employees, and operating for more than 20 years in Greece. All companies had a traceability system in operation. All companies had implemented a traceability system not because legislation required, but because they found it was a valuable business tool. In the operation level, the main problem was whether or not suppliers could provide traceability information in a useful format. All companies reported the same benefits from the traceability system: Better control of supply chain as well as better quality assurance –higher levels of food quality & safety

Grand Challenges of Traceability: The Next Ten Years

In 2007, the software and systems traceability community met at the first Natural Bridge symposium on the Grand Challenges of Traceability to establish and address research goals for achieving effective, trustworthy, and ubiquitous traceability. Ten years later, in 2017, the community came together to evaluate a decade of progress towards achieving these goals. These proceedings document some of that progress. They include a series of short position papers, representing current work in the community organized across four process axes of traceability practice. The sessions covered topics from Trace Strategizing, Trace Link Creation and Evolution, Trace Link Usage, real-world applications of Traceability, and Traceability Datasets and benchmarks. Two breakout groups focused on the importance of creating and sharing traceability datasets within the research community, and discussed challenges related to the adoption of tracing techniques in industrial practice. Members of the research community are engaged in many active, ongoing, and impactful research projects. Our hope is that ten years from now we will be able to look back at a productive decade of research and claim that we have achieved the overarching Grand Challenge of Traceability, which seeks for traceability to be always present, built into the engineering process, and for it to have "effectively disappeared without a trace". We hope that others will see the potential that traceability has for empowering software and systems engineers to develop higher-quality products at increasing levels of complexity and scale, and that they will join the active community of Software and Systems traceability researchers as we move forward into the next decade of research

Metamodel for Tracing Concerns across the Life Cycle

Several aspect-oriented approaches have been proposed to specify aspects at different phases in the software life cycle. Aspects can appear within a phase, be refined or mapped to other aspects in later phases, or even disappear.\ud Tracing aspects is necessary to support understandability and maintainability of software systems. Although several approaches have been introduced to address traceability of aspects, two important limitations can be observed. First, tracing is not yet tackled for the entire life cycle. Second, the traceability model that is applied usually refers to elements of specific aspect languages, thereby limiting the reusability of the adopted traceability model.We propose the concern traceability metamodel (CTM) that enables traceability of concerns throughout the life cycle, and which is independent from the aspect languages that are used. CTM can be enhanced to provide additional properties for tracing, and be instantiated to define\ud customized traceability models with respect to the required aspect languages. We have implemented CTM in the tool M-Trace, that uses XML-based representations of the models and XQuery queries to represent tracing information. CTM and M-Trace are illustrated for a Concurrent Versioning System to trace aspects from the requirements level to architecture design level and the implementation

Optimal choice of Voluntary traceability as a food risk management tool

Traceability systems are information tools implemented within and between firms in food chains to improve logistics and transparency or to reduce total food safety damage costs. Information about location and condition of products is critical when food safety incidents arise. This paper uses a principal-agent model to investigate the optimal choice of voluntary traceability in terms of precision of information on a given attribute at each link of a food chain. The results suggest that four scenarios may emerge for the supply chain depending on the costs of a system and whether or not the industry can internalize total food safety damages: no traceability, traceability for one link, equal traceability for all links, or different positive traceability levels across all links.Traceability, food safety, principal-agent model, Food Consumption/Nutrition/Food Safety,

CONSUMER DEMAND FOR TRACEABILITY

Consumers have become more discerning in their food consumption choices. Food safety and food quality issues have moved to the forefront of consumer concerns, industry strategies, and in some cases, government policy. A variety of private sector and public policy traceability initiatives have emerged, partly with the objective of reducing consumer information asymmetry with respect to food safety and food quality attributes. This paper examines the role of traceability systems in the food industry and distinguishes between ex-post traceback systems and ex-ante quality verification systems. Examples of voluntary private sector livestock traceability systems and public sector traceability programs are discussed, including the trade implications of mandatory traceability and labeling. The paper presents preliminary results from experimental auctions measuring consumer willingness-to-pay for traceability, food safety and on-farm production assurances.Food Consumption/Nutrition/Food Safety,
