Purpose The purpose of Verification is to ensure that selected
work products meet their specified requirements.
[PA150]
Introductory Notes The Verification process area involves the following: verification preparation, verification performance, and identification of corrective action. [PA150.N101]
Verification includes verification of the product and intermediate work products against all selected requirements, including customer, product, and product-component requirements. [PA150.N102]
Verification is inherently an incremental process because it occurs throughout the development of the product and work products, beginning with verification of the requirements, progressing through the verification of the evolving work products, and culminating in the verification of the completed product. [PA150.N103]
The specific practices of this process area build upon each other in the following way: the Select Work Products for Verification specific practice enables the identification of the work products to be verified, the methods to be used to perform the verification, and the requirements to be satisfied by each selected work product. The Establish the Verification Environment specific practice enables the determination of the environment that will be used to carry out the verification. The Establish Verification Procedures and Criteria specific practice then enables the development of verification procedures and criteria that are aligned with the selected work products, requirements, methods, and characteristics of the verification environment. The Perform Verification specific practice conducts the verification according to the available methods, procedures, and criteria. [PA150.N110]
Verification of work products substantially increases the likelihood that the product will meet the customer, product, and product-component requirements. [PA150.N104]
The Verification and Validation process areas are similar, but they address different issues. Validation demonstrates that the product, as provided (or as it will be provided), will fulfill its intended use, whereas verification addresses whether the work product properly reflects the specified requirements. In other words, verification ensures that “you built it right;” whereas, validation ensures that “you built the right thing.” [PA150.N105]
Peer reviews are an important part of verification and are a proven mechanism for effective defect removal. An important corollary is to develop a better understanding of the work products and the processes that produced them so defects can be prevented and process-improvement opportunities can be identified. [PA150.N106]
Peer reviews involve a methodical examination of work products by the producers' peers to identify defects and other changes that are needed. [PA150.N107]
Examples of
peer review methods include the following: [PA150.N109]
· Inspections
· Structured walkthroughs
Refer to the Validation process area for more information about confirming
that a product or product component fulfills its intended use when placed in its
intended environment. [PA150.R102]

about the generation and development of customer, product, and product-component
requirements. [PA150.R103]

Specific Practices by Goal
SG 1 Prepare for Verification
Preparation for verification is conducted. [PA150.IG101]
Up-front preparation is necessary to ensure that
verification provisions are embedded in product and product-component
requirements, designs, developmental plans, and schedules. Verification includes
selection, inspection, testing, analyses, and demonstration of work products.
[PA150.IG101.N101]
Methods of verification include, but are not limited to,
inspections, peer reviews, audits, walkthroughs, analyses, simulations, testing,
and demonstrations.
[PA150.IG101.N102]
Preparation also entails the definition of support tools,
test equipment and software, simulations, prototypes, and facilities. [PA150.IG101.N103]
SP 1.1-1 Select Work Products for Verification
Select the work products to be verified and the verification methods that will
be used for each. [PA150.IG101.SP101]
Work products are selected based on their contribution to
meeting project objectives and requirements, and to addressing project risks. [PA150.IG101.SP101.N104]
The work products to be verified may include those
associated with maintenance, training, and support services. The work product
requirements for verification are included with the verification methods. The
verification methods address the technical approach to work product verification
and the specific approaches that will be used to verify that specific work
products meet their requirements.
[PA150.IG101.SP101.N102]
For Software Engineering
Examples of verification methods include the following: [PA150.IG101.SP101.N102.AMP101]
· Path coverage testing
· Load, stress, and performance testing
· Decision-table-based testing
· Functional-decomposition-based testing
· Test-case reuse
· Acceptance tests
For Supplier Sourcing
Products supplied from outside of the project should be considered for verification. [PA150.IG101.SP101.N102.AMP102]
Selection of the verification methods typically begins
with involvement in the definition of product and product-component requirements
to ensure that these requirements are verifiable. Re-verification should be
addressed by the verification methods to ensure that rework performed on work
products did not cause unintended defects.
[PA150.IG101.SP101.N103]
For Integrated Product and Process Development
The verification methods should be developed concurrently and iteratively with the product and product-component designs. [PA150.IG101.SP101.N103.AMP101]
For Supplier Sourcing
Verification methods should be coordinated with suppliers to ensure applicability of the project’s methods to the supplier’s environment. [PA150.IG101.SP101.N103.AMP102]
Typical Work Products
1. Lists of work
products selected for verification [PA150.IG101.SP101.W101]
2. Verification
methods for each selected work product [PA150.IG101.SP101.W102]
Subpractices
1. Identify work products for
verification. [PA150.IG101.SP101.SubP102]
2. Identify the requirements to
be satisfied by each selected work product.
[PA150.IG101.SP101.SubP103]
Refer to the Maintain Bidirectional Traceability of Requirements specific
practice in the Requirements Management process area to help identify the
requirements for each work product. [PA150.IG101.SP101.SubP103.R101]
3. Identify the verification
methods that are available for use. [PA150.IG101.SP101.SubP104]
4. Define the verification
methods to be used for each selected work product.
[PA150.IG101.SP101.SubP105]
5. Submit for integration with
the project plan the identification of work products to be verified, the
requirements to be satisfied, and the methods to be used.
[PA150.IG101.SP101.SubP106]
Refer to the Project Planning process area for information on coordinating with
project planning. [PA150.IG101.SP101.SubP106.R101]
SP 1.2-2 Establish the Verification Environment
Establish and maintain the environment needed to support verification. [PA150.IG101.SP102]
An environment must be established to enable verification
to take place. The verification environment may be acquired, developed, reused,
modified, or a combination of these, depending on the needs of the project. [PA150.IG101.SP102.N101]
The type of environment required will depend on the work
products selected for verification and the verification methods used. A peer
review may require little more than a package of materials, reviewers, and a
room. A product test may require simulators, emulators, scenario generators,
data reduction tools, environmental controls, and interfaces with other systems.
[PA150.IG101.SP102.N102]
Typical Work Products
1. Verification
environment [PA150.IG101.SP102.W102]

4. Acquire verification support
equipment and an environment, such as test equipment and software.
[PA150.IG101.SP102.SubP104]
SP 1.3-3 Establish Verification Procedures and Criteria
Establish and maintain verification procedures and criteria for the selected
work products. [PA150.IG101.SP103]
For Integrated Product and Process Development
The verification procedures and criteria should be developed concurrently and iteratively with the product and product-component designs. [PA150.IG101.SP103.AMP101]
Verification criteria are defined to ensure that the work
products meet their requirements.
[PA150.IG101.SP103.N101]
Examples of
sources for verification criteria include the following: [PA150.IG101.SP103.N102]
· Product and product-component requirements
· Standards
· Organizational policies
· Test type
· Test parameters
· Parameters for tradeoff between quality and cost of testing
· Type of work products
For Supplier Sourcing
The verification criteria affecting a supplier should be shared with the supplier to reduce the probability that a work product will fail its verification. [PA150.IG101.SP103.N102.AMP101]
Typical Work Products
1. Verification
procedures [PA150.IG101.SP103.W101]

any tolerances allowed in observation, and other criteria for satisfying the
requirements. [PA150.IG101.SP103.SubP104]
4. Identify any equipment and
environmental components needed to support verification.
[PA150.IG101.SP103.SubP105]
SG 2 Perform Peer Reviews
Peer reviews are performed on selected work products. [PA150.IG102]
Peer reviews involve a methodical examination of work
products by the producers' peers to identify defects for removal and to
recommend other changes that are needed.
[PA150.IG102.N101]
The peer review is an important and effective engineering
method implemented via inspections, structured walkthroughs, or a number of
other collegial review methods.
[PA150.IG102.N102]
Peer reviews are primarily applied to work products
developed by the projects, but they can also be applied to other work products
such as documentation and training work products that are typically developed by
support groups.
[PA150.IG102.N103]
SP 2.1-1 Prepare for Peer Reviews
Prepare for peer reviews of selected work products.
[PA150.IG102.SP101]
Preparation activities for peer reviews typically include
identifying the staff who will be invited to participate in the peer review of
each work product, identifying the key reviewers who must participate in the
peer review, preparing and updating any materials that will be used during the
peer reviews (such as checklists and review criteria), and scheduling peer
reviews.
[PA150.IG102.SP101.N101]
Typical Work Products
1. Peer review

5. Peer review
training material [PA150.IG102.SP101.W105]
6. Selected work
products to be reviewed [PA150.IG102.SP101.W106]
Subpractices
1. Determine what type of peer
review will be conducted. [PA150.IG102.SP101.SubP101]
Examples of types of peer reviews include the following:
[PA150.IG102.SP101.SubP101.N101]
· Inspections
· Structured walkthroughs
· Active reviews
2. Define requirements for
collecting data during the peer review. [PA150.IG102.SP101.SubP102]
Refer to the Measurement and Analysis process area for information on
identifying and collecting data. [PA150.IG102.SP101.SubP102.R101]
3. Establish and maintain entry
and exit criteria for the peer review.
[PA150.IG102.SP101.SubP103]
4. Establish and maintain
criteria for requiring another peer review.
[PA150.IG102.SP101.SubP104]
5. Establish and maintain
checklists to ensure that the work products are reviewed consistently.
[PA150.IG102.SP101.SubP105]
Examples of items addressed by the checklists include the following: [PA150.IG102.SP101.SubP105.N102]
· Rules of construction
· Design guidelines
· Completeness
· Correctness
· Maintainability
· Common defect types
The checklists are modified as
necessary to address the specific type of work product and peer review. The
peers of the checklist developers and potential users review the checklists.
[PA150.IG102.SP101.SubP105.N101]
6. Develop a detailed peer review
schedule, including the dates for peer review training and for when materials
for peer reviews will be available. [PA150.IG102.SP101.SubP106]

enable participants to adequately prepare for the peer review.
[PA150.IG102.SP101.SubP108]
9. Assign roles for the peer
review as appropriate. [PA150.IG102.SP101.SubP109]
Examples of roles include the following:
[PA150.IG102.SP101.SubP109.N101]
· Leader
· Reader
· Recorder
· Author
10. Prepare for the peer review by reviewing
the work product prior to conducting the peer review.
[PA150.IG102.SP101.SubP110]
Conduct peer reviews on selected work products and identify issues resulting
from the peer review. [PA150.IG102.SP102]
One of the purposes of conducting a peer review is to find
and remove defects early. Peer reviews are performed incrementally, as work
products are being developed. These reviews are structured and are not
management reviews.
[PA150.IG102.SP102.N101]
Peer reviews may be performed on key work products of
specification, design, test, and implementation activities and specific planning
work products.
[PA150.IG102.SP102.N102]
The focus of the peer review should be on the work product
in review, not on the person who produced it. [PA150.IG102.SP102.N103]
When issues arise during the peer review, they should be
communicated to the primary developer of the work product for correction. [PA150.IG102.SP102.N104]
Refer to the Project Monitoring and Control process area for information
about tracking issues that arise during a peer review.
[PA150.IG102.SP102.N104.R101]
Peer reviews should address the following guidelines:
there must be sufficient preparation, the conduct must be managed and
controlled, consistent and sufficient data must be recorded (an example is
conducting a formal inspection), and action items must be recorded. [PA150.IG102.SP102.N105]
Typical Work Products
1. Peer review
results [PA150.IG102.SP102.W101]
2. Peer review

5. Identify action items and
communicate the issues to relevant stakeholders.
[PA150.IG102.SP102.SubP105]
6. Conduct an additional peer
review if the defined criteria indicate the need.
[PA150.IG102.SP102.SubP106]
7. Ensure that the exit criteria
for the peer review are satisfied. [PA150.IG102.SP102.SubP107]
SP 2.3-2 Analyze Peer Review Data
Analyze data about preparation, conduct, and results of the peer reviews. [PA150.IG102.SP103]
Refer to the Measurement and Analysis process area for more information
about obtaining and analyzing data.
[PA150.IG102.SP103.R101]

2. Peer review
action items [PA150.IG102.SP103.W102]
Subpractices
1. Record data related to the
preparation, conduct, and results of the peer reviews.
[PA150.IG102.SP103.SubP101]
Typical data are product name,
product size, composition of the peer review team, type of peer review,
preparation time per reviewer, length of the review meeting, number of defects
found, type and origin of defect, etc. Additional information on the work
product being peer reviewed may be collected, such as size, development stage,
operating modes examined, and requirements being evaluated.
[PA150.IG102.SP103.SubP101.N101]
2. Store the data for future
reference and analysis. [PA150.IG102.SP103.SubP102]
3. Protect the data to ensure
that peer review data are not used inappropriately.
[PA150.IG102.SP103.SubP103]
Examples of inappropriate use of peer review data include using data to evaluate
the performance of people and using data for attribution.
[PA150.IG102.SP103.SubP103.N101]
4. Analyze the peer review data. [PA150.IG102.SP103.SubP104]
SG 3 Verify Selected Work Products
Selected work products are verified against their specified requirements. [PA150.IG103]
Perform verification on the selected work products.
[PA150.IG103.SP101]
Verifying products and work products incrementally
promotes early detection of problems and can result in the early removal of
defects. These results of verification save considerable cost of fault isolation
and rework associated with troubleshooting problems.
[PA150.IG103.SP101.N101]
(For users of the continuous representation, this is a
capability level 1 specific practice. Verification processes at capability level
1 or 2 may not include procedures and criteria, which are created in the
Establish Verification Procedures and Criteria specific practice at capability
level 3. When there are no procedures or criteria established, use the methods
established by the Select Work Products for Verification specific practice to
accomplish capability level 1 performance.)
[PA150.IG103.SP101.N102]
Typical Work Products
1. Verification
results [PA150.IG103.SP101.W101]
2. Verification
reports [PA150.IG103.SP101.W102]
3.
Demonstrations [PA150.IG103.SP101.W103]
4. As-run
procedures log [PA150.IG103.SP101.W104]
Subpractices
1. Perform verification of
selected work products against their requirements.
[PA150.IG103.SP101.SubP102]
2. Record the results of
verification activities. [PA150.IG103.SP101.SubP103]
3. Identify action items
resulting from verification of work products.
[PA150.IG103.SP101.SubP104]
4. Document the “as-run”
verification method and the deviations from the available methods and procedures
discovered during its performance. [PA150.IG103.SP101.SubP105]
SP 3.2-2 Analyze Verification Results and Identify Corrective Action
Analyze the results of all verification activities and identify corrective
action. [PA150.IG103.SP102]
Actual results must be compared to established
verification criteria to determine acceptability.
[PA150.IG103.SP102.N101]
The results of the analysis are recorded as evidence that
verification was conducted.
[PA150.IG103.SP102.N102]
For each work product, all available verification results
are incrementally analyzed and corrective actions are initiated to ensure that
the requirements have been met. Since a peer review is one of several
verification methods, peer review data should be included in this analysis
activity to ensure that the verification results are analyzed sufficiently.
Analysis reports or “as-run” method documentation may also indicate that bad
verification results are due to method problems, criteria problems, or a
verification environment problem.
[PA150.IG103.SP102.N103]
Refer to the corrective action practices of Project Monitoring and Control
process area for more information on implementing corrective action.
[PA150.IG103.SP102.N103.R101]

2. Based on the established
verification criteria, identify products that have not met their requirements or
identify problems with the methods, procedures, criteria, and verification
environment. [PA150.IG103.SP102.SubP102]
3. Analyze the verification data
on defects. [PA150.IG103.SP102.SubP103]
4. Record all results of the
analysis in a report. [PA150.IG103.SP102.SubP104]
5. Use verification results to
compare actual measurements and performance to technical performance parameters. [PA150.IG103.SP102.SubP105]
6. Provide information on how
defects may be resolved (including verification methods, criteria, and
verification environment) and formalize it in a plan.
[PA150.IG103.SP102.SubP106]
For Supplier Sourcing
Distribute pertinent verification results to the supplier of the work product. [PA150.IG103.SP102.SubP106.AMP101]
