'Verification Importance' primarily ensures that:
System elements meet system and design requirements
What activities are included in the Verification process?
Preparing for verification, performing verification, and managing results of verification
What is involved in preparing for verification?
Establishing a list of entities to be verified and identifying constraints
What is considered as entities to be verified in the Verification process?
System architecture, prototypes, and models
What are constraints in the context of preparing for verification?
Contracts and regulations
What are the methods included in verification actions?
Inspection, analysis, demonstration, and testing
What is the purpose of verification strategy?
Incorporating requirements from the verification strategy into system requirements, architecture, and design
What are verification procedure requirements?
Requirements that drive the formulation of steps and actions for a given verification procedure
What is the caution given to the SE practitioner regarding verification activities?
To substitute verification of the realized system with the verification results obtained using models and simulations
Why is it important to conduct verification activities earlier in the life cycle?
To reduce the risk of issues and anomalies being discovered during system integration
What is the potential risk of substituting verification of the realized system with the verification results obtained using models and simulations?
Reduced confidence level and risk of the realized system failing system validation
What should the SE practitioner resist doing in relation to verification activities?
Substituting verification of the realized system with simulation results
What is the significance of knowing the status of verification activities, anomalies discovered, and noncompliances in a project?
Enables better management of budget, schedule, and estimation of risks
What can help reduce the risk of issues and anomalies being discovered during system integration, verification, and validation activities?
Conducting verification activities earlier in the life cycle
Why should the SE practitioner avoid substituting verification of the realized system with simulation results?
Reduces confidence level and adds risk of failure during system validation
What is a potential consequence of substituting physical hardware with simulation results for verification?
Reduced confidence level and increased risk of failure during system validation
What is the purpose of comparing verification results against verification success criteria?
To determine if an entity meets them with acceptable confidence
What process is used to establish and maintain baselines according to the text?
Configuration Management
When should early planning for verification begin?
When system architecture and design are being defined
What should be considered when deciding whether to reduce verification activities?
A risk-based approach
What should verification actions and results be traced back to for bidirectional traceability?
System requirements
Why should verification planning begin early in the system life cycle?
To address discrepancies and errors early
What action should be taken if additional resources become available for verification?
Deepen verification to reduce risk
What characteristic should good verification activities include?
Verifying stakeholder or system requirements against their sources
Study Notes
- Verification results are compared against verification success criteria to determine if an entity meets them with acceptable confidence.
- Operational incidents and problems are captured and tracked until resolution, with changes handled through Project Assessment and Control and Configuration Management processes.
- Verification artifacts are traced back to system architecture and design characteristics or requirements for bidirectional traceability.
- Configuration Management process is used to establish and maintain baselines, with verification identifying candidate items for baselines.
- Early planning for verification begins when system requirements are defined.
- Verification activities should not be reduced without using a risk-based approach.
- A verification action includes an entity, reference item, expected result, verification strategy/method, and level of integration.
- Verification actions can include verifying stakeholder or system requirements against their sources and good requirement characteristics.
- Verification results are compared to expected results as defined by verification success criteria to determine acceptable conformance.
- Verification actions and results should be traced back to system requirements for bidirectional traceability.
- Verification activities should not be conducted only late in the schedule or reduced due to budget or schedule concerns, as discrepancies and errors are more costly to correct later in the system life cycle.
- Verification planning should begin early in the system life cycle, with verification success criteria, method, and strategy defined and approved when system requirements are being defined.
- If additional resources become available, verification should be deepened to reduce risk and increase the degree of confidence.
