Traceability matrix is of three types:

1. Vertical Traceability matrix.
2. Transversal Traceability Matrix
3. Horizontal Traceability matrix.

Vertical Traceability matrix is high level document which map the
requirements to all phases of the Software development cycle. i.e. Unit testing,
Component Integration testing, System Integration testing, Smoke/Sanity testing,
System Testing, Acceptance testing...etc.

Vertical traceability is related to the bidirectional trace that could be
registered from the textual requirements, going through graphical functional
requirements and at last to the phases of the software development lifecycle
like: design, coding, testing, and so on.

Transversal traceability is related to the bidirectional trace that could be
registered from the textual requirements, through the graphical non-functional
requirements, the architectural policies, and in the end to the architectural
mechanisms (architectural decisions).

 Horizontal Traceability matrix is used for Coverage analysis, when a
requirement changed it will used to identify the Test cases prepared on that
requirement. Horizontal traceability is related to the bidirectional trace that
could be registered from the graphical non-functional requirements or even the
architectural policies, or mechanisms to the architectural integration model and
at last the design phase.
