Requirements Allocation and Traceability Diagram (Drag and Drop)

Allocate requirements to systems and build parent/child traceability by dragging them on a diagram, in Reqi requirements management software.

The canvas nests three deep - a level column holds system boxes, which hold requirement cards - so a requirement's system, its derivation level and its place in the traceability tree are readable at once.

Arranging the diagram

• Drag a system box, or a whole level column, anywhere on the canvas
• Boxes snap into alignment, with guide lines showing the match, and never overlap
• Your layout is saved per project; a reset button returns to the automatic one

Changing allocation by dragging

• Drag a requirement onto another system to move that allocation; its other allocations are left alone
• A placeholder shows exactly where the requirement will land
• Drop on empty canvas to pick one or more systems, or send it back to Unallocated

Building the derivation tree

• Drag from a card's +/- handles to draw a parent or child link
• Drop a link inside a system box to author a new requirement with the system and relationship filled in
• "+ Add" on any system adds a new or existing requirement
• Unlink removes every parent and child at once without deleting the requirement

Every change is permission-checked and written to the requirement's audit history.
