Objectives/Scope Systems engineering techniques, particularly requirements management, are critical to realizing the value of digital transformation to improve capital project delivery. Drawing on the results of a case study, this paper will demonstrate the value of using digital requirements management to exchange information through a project lifecycle, specifically showing benefits in the integrity of data transfer; more efficient procurement lifecycle; more robust deviation management; and bidirectional traceability of requirements, including full visibility and end to end verification and validation. Methods, Procedures, Process A requirement is a capability to which a project outcome (product or service) should conform, and the purpose of requirements management is to ensure that an organization documents, verifies and validates these capabilities. In this case study the operator provides their technical specifications in the form of requirements. These requirements are then imported into the EPC's PLM platform, where they are supplemented with additional information from the EPC's engineers to create a requirements-based requisition package. This is then transmitted to the equipment supplier, where it is reviewed and, for the purposes of the case study, reviewed for completeness. To test the ability to identify changes and deviations, the EPC engineer modified the requirements and the file was transferred to both the operator and equipment supplier to ensure the changes were transferred and were identifiable. The case study also demonstrates how verification activities (testing, commissioning, etc.) can be linked to requirements; passed through the supply chain and be modified to capture changes to the status of the activity (such as test results). Results, Observations, Conclusions The case studies described show how requirements can be exchanged between operator, EPC and equipment supplier without any loss of data. It will also show how this approach allows a data driven approach, as opposed to a document driven approach, to be deployed in the requisitioning process, which could facilitate substantial reduction in the procurement lifecycle. This is achieved by removing extraneous information exchanged between the companies; the removal of swivel chair solutions, where data is extracted from one system and transferred to another; and expediting the bid evaluation stage. Finally, the case study will demonstrate how this approach could be extended beyond the purchase order to provide a direct link between specific requirements and testing (FATs) or commissioning activities, which facilitates a more efficient process for verification as well as ensuring a digital record of the entire lifecycle of a package. The case study highlighted the importance of aligning data model and developing workflows, these findings are captured in the lessons learned section and have been shared with the International Association of Oil and Gas Producers (IOGP) Requirements Digitalization Task Force (RDTF). Novel/Additive Information The paper will also include a vision of requirements models can be used to establish a holistic requirements model of a project, including the interdependencies of different system components. The case study will also demonstrate how the adoption of a common data standard for requirements allows a software agnostic solution that can be adopted by all.

As we witness the advancement of U.S. high-speed rail initiatives, the country can look towards its European and Asian counterparts for best practices and lessons learned from their decades of high-speed rail design and operations. These experiences gained may be applicable towards projects such as the Texas Central Railway and the California High-Speed Rail Project. This chapter will address the events of 2009 that have brought domestic high-speed rail to the forefront of U.S. rail transportation. This includes the new FRA Tier I and proposed Tier III criteria, challenges associated with each FRA tier of operation, overseas interoperability efforts, snapshots of international experiences (from policy and technological perspectives), the holistic system-based approach to safety, ongoing efforts of the FRA Engineering Task Force, and additional challenges and opportunities moving forward.

This essay explores the origins of the 2009 U.S. Navy Task Force Climate Change (TFCC) from the perspective of its founder and initial director. The director's background is described briefly, along with events and actions of Navy leadership that led to creating the TFCC. The essay states five lessons learned within the context of setting the direction and tone for change in a large organization and examines five areas in which the TFCC arguably has made a positive difference to the U.S. Navy. The essay provides an overview of U.S. Navy and national climate-related actions after the author's tenure as director of the TFCC, and concludes by addressing climate change risks within the context of current efforts to understand and manage adverse impacts from the COVID-19 virus.

The San Francisco–Oakland Bay Bridge, connecting San Francisco and the East Bay, is one of the most heavily traveled corridors in the nation. In an effort to address traffic congestion in this corridor, the Bay Area Congestion Pricing Task Force—a group of business, environment, public interest, and government organizations—has been examining the viability of variable tolls on the Bay Bridge. Tolls would be higher during peak commute hours when demand is highest and lower in off-peak hours when the bridge has excess capacity. This supply-and-demand-based concept is known as congestion pricing. The federally sponsored planning phase of the Bay Bridge congestion-pricing demonstration program commenced in the fall of 1993. Its purpose was to determine the most feasible alternatives for reducing congestion on the San Francisco–Oakland Bay Bridge through implementing a congestion-pricing program. The process by which the task force developed a congestion-pricing proposal for the Bay Bridge is described, as are the lessons that have been learned along the way.

Fish make an important contribution to micronutrient intake, long-chained polyunsaturated omega-3 fatty acids (n-3 LC-PUFAS), and animal protein, as well as ensuring food and nutrition security and livelihoods for fishing communities. Micronutrient deficiencies are persistent in sub-Saharan Africa (SSA), contributing to public health issues not only in the first 1000 days but throughout adolescence and into adulthood. School feeding programs (SFPs) and home-grown school feeding programs (HGSF), which source foods from local producers, particularly fisherfolk, offer an entry point for encouraging healthy diets and delivering essential macro- and micronutrients to schoolchildren, which are important for the continued cognitive development of children and adolescents and can contribute to the realization of sustainable development goals (SDGs) 1, 2, 3, 5, and 14. The importance of HGSF for poverty alleviation (SDG1) and zero hunger (SDG 2) have been recognized by the United Nations Hunger Task Force and the African Union Development Agency–New Partnership for African Development (AUDA-NEPAD), which formulated a strategy for HGSF to improve nutrition for the growing youth population across Africa. A scoping review was conducted to understand the lessons learned from SFPs, which included fish and fish products from small-scale producers, identifying the challenges and best practices for the inclusion of fish, opportunities for improvements across the supply chain, and gaps in nutritional requirements for schoolchildren which could be improved through the inclusion of fish. Challenges to the inclusion fish in SFPs include food safety, supply and access to raw materials, organizational capacity, and cost, while good practices include the engagement of various stakeholders in creating and testing fish products, and repurposing fisheries by-products or using underutilized species to ensure cost-effective solutions. This study builds evidence of the inclusion of nutritious fish and fish products in SFPs, highlighting the need to replicate and scale good practices to ensure sustainable, community-centred, and demand-driven solutions for alleviating poverty, malnutrition, and contributing to greater health and wellbeing in adolescence.
