Reviews
When you are ready for team members to review
requirement artifacts, you can create a review.
In reviews, team members review requirement artifacts,
record comments about them, and approve or
disapprove them within the context of the project.
A review can contain individual artifacts or can be
based on a collection.
You can add team members to reviews, assign them
specific roles, and set up automatic email notifications.

 Rework can consume
30-50% of development
costs. Requirement
errors account for 70-
85% of rework costs.
 Preventing requirement
errors and catching
them early can greatly
reduce rework.

Relative Cost to Correct a Defect

Development at a Baldrige Winner,“ Proceedings of ELECTRO
`94, Boston, Massachusetts, May 12, 1994, pp. 167-180.

Reviews and approvals
Generally, a review and approval process includes
these steps:
 Presenting and making the information available
 Defining the review criteria
 Reviewing or inspecting the requirement artifacts
 Collecting comments and feedback for improvement
 Gaining acceptance of the requirements
 Getting formal sign-off for the requirements, if required
Generate review documents only in these
circumstances:
• When there is value to both the
stakeholders and development team
• When your organizational process
requires them; for example, for archival
purposes or for using your organization’s
content-management system and
approval process
• When other parties who do not have
access to the project area need
information
• For contractual purposes
With the Requirements Management (RM)
application, teams can reduce their
dependence on large specification
documents.

Types of reviews
Type Description When to use
Formal Reviewers see versions
of artifacts that were
current when the review
was created
 Artifacts are in flux and
you want controlled
reviews on static versions
 You need specific versions
of artifacts to be approved
Informal Reviewers see the latest
version of the artifacts
when they start the
review
 Artifacts are not changing
 You do not need specific
versions to be approved
Use informal reviews to provide feedback
when team members are jointly authoring
requirements.
In a formal review, the version of embedded
artifacts is "frozen" in the artifacts that are in
the review.

Reviewer roles
The review creator adds team members to the review and
assigns a role to each reviewer.
Role Required action
Approver Must approve, disapprove, or abstain from
reviewing each artifact in the review for the
review to move forward.
Reviewer Must review or abstain from reviewing each
artifact in the review for the review to move
forward.
Optional reviewer Optionally review or abstain from reviewing
the artifacts. The review moves forward
even if optional reviewers do not respond.

Review lifecycle states
State Description
Draft The initial state of the review as it is being
created.

starts the review. Participants are notified.

to add participants or roles, or to change
artifacts.
