Quality Assurance
9.2 Quality Assurance Program
The LBNF/DUNE Systems Engineering teams maintain a LBNF/DUNE CMP [1], which identifies the LBNF project Configuration Items Data List (CIDL) and Interface Control matrices that provide the tier structure for the flow down of QA plans, with the LBNF/DUNE QA plan as the top tier.
With the assistance of the LBNF/DUNE QA manager, the consortia will develop specific QA plans for component or system QA. Due to the limited scope of work of some consortia, they may elect to work under the LBNF/DUNE QA plan for their scope of work. In case of conflict between sets of QA requirements, DUNE technical coordination will provide resolution.
With many institutions carrying responsibility for various aspects of the project, institutional QA plans will be reviewed by DUNE technical coordination to ensure compliance with the LBNF/DUNE QA plan. Using a graded approach, supplements to institutions existing plans will be implemented for their DUNE scope of work, if necessary.
Overall QA supervision, including all activities described above, is the responsibility of the DUNE TC.
9.2.1 Responsibility for Project Management
The DUNE consortium leaders manage their projects and are responsible for achieving perfor- mance goals. The LBNF/DUNE QA manager is responsible for ensuring that a quality system is established, implemented, and maintained in accordance with requirements. The LBNF/DUNE QA manager reports to the DUNE TC and provides oversight and support to consortium leaders to ensure a consistent quality program.
DUNE consortium leaders are responsible for quality within their project and report QA issues to the DUNE TC and LBNF/DUNE QA manager. DUNE consortium leaders designate QA represen- tatives within their organization and delegate, as appropriate, work defined in the LBNF/DUNE QA plan, as shown in Fig. 9.2.
The DUNE consortium leaders retain overall responsibility for QA even though they have desig- nated a QA representative.
9.2.2 Levels of Authority and Interface
The DUNE Management Plan, the LBNF/DUNE PMP and the LBNF/DUNE QA plan define the responsibility, authority and interrelation of personnel who manage, perform, and verify work that affects quality. The QA plan defines the QA roles and responsibilities of the DUNE project.

Chapter 9: Quality Assurance 9–95
All consortium members are responsible for the quality of the work that they do and for using guidance and assistance that is available. Each has the authority to stop work and report adverse conditions that affect quality of DUNE products to their respective DUNE consortium leader and the LBNF/DUNE QA manager. The consortium leader responsible for DUNE components or systems is required to determine and document their acceptance criteria. DUNE personnel at each level are responsible for evaluation of quality through self-assessments; however, independent qual- ity assessments may also be requested by project management. The LBNF/DUNE QA manager is responsible for development, implementation, assessment, and improvement of the QA program.
The LBNF/DUNE QA manager is responsible for periodically reporting on the performance of the quality system to the DUNE TC for review and as a basis for improving the quality system. The DUNE TC may call for QA plan readiness assessments as the project nears major milestones. The DUNE TC, consortium leaders, and LBNF/DUNE QA manager are all responsible for providing the resources needed to conduct the project successfully, including those required to manage, perform, and verify work that affects quality.
9.2.3 Quality Assurance Organization
LBNF/DUNE QA manager may request personnel from the DUNE project to act on behalf of the LBNF/DUNE QA manager to perform quality assurance functions, based on need, in accordance with the graded approach described above. The requested personnel must possess qualifications or receive the appropriate training required to perform these functions.
The DUNE QA Specialist will be responsible for the following activities:
• Cooperatively develop, monitor, and control DUNE QA procedures to assure compliance with DUNE standards and applicable laws;
• Provide assistance for QA/QC matters in project plans, including strategizing technical solutions and alternatives on QA/QC matters and assist in developing testing plans with project team members;
• Participate in audits, site inspections, accident investigations, and monitor trend analysis to identify areas of concern and implement improvements;
• Interact with all stakeholders on QA issues;
• Provide guidance and interpretation on routine and complex QA matters and problems; and
• Participate in reviews at collaborating institutions.
Each consortium selects a QA representative. Each consortium QA representative is responsible for overall coordination of quality requirements to assure they meet consortium objectives. The QA representative is expected to
• oversee the consortium fabrication facilities for quality performance;
• interface with the DUNE QA specialist on consortia QA related matters;
• monitor the status of all required testing based on the consortium QC plan;
Chapter 9: Quality Assurance 9–96
• make sufficient fabrication facility visits to determine adequacy of QC system performance:
check certifications of materials and equipment delivered to the facility, spot check workman- ship, observe testing procedures; and
• make or arrange production progress reviews during the fabrication cycle in coordination with technical coordination and the Joint Project Office (JPO) review office .
Figure 9.2 shows the interface between the LBNF/DUNE QA organization and the consortium QA representatives. These interfaces will remain when the equipment is shipped to the far site for installation, but the names may change for the consortium QA representatives. The consortium QA representatives remain responsible for QA/QC during the detector installation process.
