Jäljitettävyyskartoitus

Jäljitettävyyskartoitus, often translated as traceability mapping or mapping of traceability, is a process used in various fields, particularly in software development, manufacturing, and supply chain management, to document and visualize the relationships between different elements. The core idea is to establish a clear line of sight from a requirement or a starting point to its final implementation or outcome, and vice versa.

In software engineering, traceability maps connect requirements to design documents, code modules, test cases, and even bug reports. This allows teams to understand how a specific requirement is addressed in the codebase, which tests are relevant for verifying it, and what impact a change in a requirement might have on other parts of the system. This is crucial for impact analysis, change management, and ensuring that all specified functionalities are implemented and tested.

In manufacturing and supply chains, traceability mapping focuses on tracking products and their components from origin to destination. This involves documenting the sources of raw materials, manufacturing processes, distribution channels, and final sale. Such mapping is essential for quality control, regulatory compliance, product recalls, and ensuring ethical sourcing. It provides a historical record of a product's journey, enabling swift identification of issues and their root causes.

The creation of traceability maps can involve various tools and techniques, ranging from simple spreadsheets and diagrams to sophisticated requirements management or product lifecycle management (PLM) software. The level of detail and the specific elements mapped depend on the industry, project complexity, and the intended purpose of the mapping. Ultimately, effective traceability mapping enhances transparency, facilitates better decision-making, and improves overall quality and accountability.
