Resum	The Harris matrix is a method for recording and diagramming the stratigraphic sequence of an archaeological site as a partial-order diagram of individually defined contexts. Devised by Edward C. Harris at the Winchester excavations in 1973 and codified in his Principles of Archaeological Stratigraphy, it treats every deposit, cut, and interface as a separate stratigraphic unit and reduces the tangle of physical relationships among them to a minimal directed acyclic graph that expresses only relative temporal order. By distinguishing physical superposition from temporal sequence and stripping away redundant relationships through transitive reduction, the matrix turns the three-dimensional complexity of a dig into a single, auditable diagram. It is the structural backbone of single-context recording and the standard interface between excavation and chronological modeling.	Formation process analysis is the framework for identifying the cultural and natural processes that transform materials from their living, systemic context into the archaeological record we excavate. Developed by Michael Schiffer within behavioral archaeology and codified in his 1987 Formation Processes of the Archaeological Record, it insists that the archaeological record is not a fossilized snapshot of past life but the cumulative product of how things were discarded, lost, reused, and disturbed (cultural or C-transforms) and how they then decayed, moved, and mixed in the ground (natural or N-transforms). Because every deposit has been filtered and rearranged by these processes, sound inference about past behavior requires first reconstructing the formation history of the record and correcting for it. Formation process analysis is therefore foundational to interpretation, linking excavation, geoarchaeology, and taphonomy.
