Explanation
Organize around value is one of the 10 SAFe Lean-Agile Principles that guide the implementation of SAFe in any context. It states that enterprises must align their people, processes, and technology to the full and continuous flow of value that delivers customer and business outcomes. This principle helps enterprises to eliminate silos, reduce handoffs, improve collaboration, and optimize value streams. It also enables faster feedback, shorter lead times, higher quality, and better economics.

Explanation
Knowledge is one of the factors that affect the size of a story. It refers to what is known or unknown about the story, such as the requirements, the design, the technology, the domain, the dependencies, and the risks. The more unknowns there are, the larger the story size will be, as it will require more effort, complexity, and uncertainty to implement. Knowledge is one of the components of the story point estimation technique, which is a relative measure of the effort required to implement a story. Story points take into account the volume, complexity, knowledge, and uncertainty of the work. References: Story - Scaled Agile Framework, Story Point

Explanation
Reducing the batch sizes of work is critical to improving flow, as it enables faster delivery of value, lower risk, higher quality, and better feedback1. Batch size is the amount of work that moves as a unit through the value stream2. Smaller batches reduce the cycle time, the total time from the beginning to the end of the process to provide value to a customer3. Smaller batches also reduce the variability and uncertainty in the system, leading to less waste and rework2. SAFe provides several practices to reduce the batch sizes of work, such as using User Stories, Features, and Minimum Viable Products (MVPs) as units of work, applying Continuous Integration (CI) and Continuous Delivery (CD) pipelines, and limiting Work in Process (WIP)1.
