'Focus on Customer Value' is a key principle in Agile project management that emphasizes delivering products that truly meet the needs and expectations of the customer. It prioritizes understanding of the customer’s needs over technical or organizational constraints, promoting customer collaboration and feedback to maximize product value. The Agile team aims to constantly and incrementally deliver value to users, learning from their feedback and incorporating it into future cycles of development. This approach nurtures a culture of continuous improvement, adapting to customers’ changing needs, and engaging with them to maintain relevance, engagement, and satisfaction.

'Ongoing Prioritization' is based on realizing product value as early as possible. In Agile context, teams are not locked into a long-term fixed idea of what needs to be built. Instead, they continuously re-evaluate their list of work to ensure they are focusing on the most important items, in terms of delivering customer value. Predictive models are not used; rather, work is prioritized on real and current data. These ongoing assessments allow Agile teams to adapt and respond to changes quickly, ensuring that the product development efforts produce the maximum possible value.

'Value-Based Incremental Delivery' aims at delivering smaller, usable components of the product to customers in increments, rather than delivering everything at once at the end. These components or increments are prioritized based on their value to the customer and the project. Delivering in increments translates into early and frequent feedback while reducing the risk of total project failure. It also lets teams see regularly that they’re achieving valuable outcomes, promoting motivation and allowing greater transparency and sense of progress.

'Fast and Flexible Response to Changes' focuses on the ability of an Agile team to quickly adapt in response to changes. Agile methodologies employ short, time-boxed iterations which allow for frequent reassessment of priorities. If something needs to be changed or added, they quickly adjust their future plans, and take it on board. This flexibility supports creating high-quality products that meet current customer needs - even when those needs change unexpectedly.

'Ongoing Real-Time Stakeholder Engagement' emphasizes the importance of involving the stakeholders— including customers, users, and any other parties impacted by the project — in the product development process, ensuring the delivered product is relevant, useful, and valuable to all. Agile teams seek active stakeholder participation, feedback, and decision-making through various practices such as regular updates, sprint reviews, and product demonstrations, which allows them to understand stakeholder perspective better and incorporate it into the final deliverable.

This concept refers to the approach where decisions are made based on the value they would generate for the business rather than being guided merely by costs or schedule. Factors such as customer satisfaction, revenue potential, strategic alignment, and risk mitigation also come to the fore. It advocates making the best use of available resources and directing them towards the most valuable aspects of the project. This ensures that the project stays aligned with the overall business goals and objectives, and can deliver real value to all stakeholders involved.

Risk management is another integral part of value-driven delivery. It involves proactive anticipation, assessment, and mitigation of risks that could potentially derail a project. The key aspect of risk management in agile methods is continuous attention to risks throughout the project, making it a part of daily tasks, reviews, retrospectives, and other agile practices. This approach encourages early detection and resolution of issues, thus minimizing impacts on project value delivery.

In the context of value-driven delivery, verification and validation are essential for ensuring that the product is not only being built correctly (verification) but is also the right product being built (validation). Frequent verification and validation ensure that any deviation from the desired values can be spotted and dealt with promptly. It keeps the development strictly aligned with the customer's needs and desires. It also provides early value realizations and minimizes waste by catching errors and deviations early.

Forward-looking planning that is adaptive to changes forms another core value-driven delivery concept of agile project management. It's about making flexible plans for the future yet being open to adjust them as the project evolves. This planning takes into account the learning that happens throughout the project and enables the team to adjust its course of actions accordingly. This approach ensures continuous value delivery and helps in maintaining alignment with the overarching business strategy.

Product backlog management is key in agile projects. An optimized product backlog is effectively prioritized using a value-driven approach, accommodating the most valuable features and requirements at the top. The backlog provides a visible, single source of requirements for the product, managed and prioritized by a product owner. It's dynamic, meaning its items are continually evolving based on business value, emerging information, user feedback and changes in strategic direction. Effective product backlog management allows the project to deliver maximum value in minimal time.
