Types Of Traceability Matrix

Types Of Traceability Matrix

1)Baseline Traceability Matrix

Description

A table that documents the requirements of the system for use in subsequent stages to confirm that all requirements have been met.

Size and Format

Document each requirement to be traced. The requirement may be mapped to such things as a hardware component, an application unit, or a section of a design
specification.

2)Building a Traceability Matrix

->Use a Traceability Matrix to:

* verify and validate system specifications

* ensure that all final deliverable documents are included in the system specification, such as process models and data models

* improve the quality of a system by identifying requirements that are not addressed by configuration items during design and code reviews and by identifying extra

configuration items that are not required. Examples of configuration items are software modules and hardware devices

* provide input to change requests and future project plans when missing requirements are identified

* provide a guide for system and acceptance test plans of what needs to be tested.

Need for Relating Requirements to a Deliverable

Taking the time to cross-reference each requirement to a deliverable ensures that a deliverable is consistent with the system requirements. A requirement that cannot
be mapped to a deliverable is an indication that something is missing from the deliverable. Likewise, a deliverable that cannot be traced back to a requirement may mean the system is delivering more than required.

Use a Traceability Matrix to Match Requirements to a Deliverable

There are many ways to relate requirements to the deliverables for each stage of the system life cycle.
One method is to:

* create a two-dimensional table

* allow one row for each requirements specification paragraph (identified by paragraph number from the requirements document)

* allow one column per identified configuration item (such as software module or hardware device)

* put a check mark at the intersection of row and column if the configuration item satisfies the stated requirement
