What information does a cumulative flow diagram provide?
Correct Answer: C
According to the SAFe for Teams SP (6.0) - SAFe Practitioner handbook and study guide, a cumulative flow diagram (CFD) is a visual tool that shows the amount of work in each stage of a process over time. It helps teams monitor the flow of work, identify bottlenecks, and improve efficiency. A CFD provides the following information: * The total number of work items in the system (the height of the diagram) * The number of work items in each stage of the process (the width of each band) * The lead time for each work item (the horizontal distance from the left to the right edge of the diagram) * The cycle time for each work item (the horizontal distance from one stage to another within the diagram) * The throughput of the system (the slope of the diagram) * The stability of the system (the smoothness of the diagram) By analyzing the CFD, teams can identify current bottlenecks, such as: * A large amount of work in progress (WIP), which indicates a high lead time and low throughput * A wide band in a specific stage, which indicates a long cycle time and a potential impediment * A steep or jagged slope, which indicates a high variability and unpredictability References: Exam Study Guide: SP (6.0) - SAFe Practitioner, SAFe for Teams - Know Your Role on an Agile Team, Cumulative Flow Diagram SAFe: Complete Guide

Question 53
The "3 Cs" is a popular guideline for writing user stories. What does each of the three Cs represent? (Choose three.)
Correct Answer: A,D,E
= The "3 Cs" of user stories are three criteria that help to ensure that the requirements in your story are clear, complete, and correct. These three criteria are Card, Conversation, and Confirmation1. * Card: A user story card is a placeholder for a conversation. It is a brief and informal description of a software feature written from the perspective of the end user. It captures the essence of the user's need, without going into too much detail or technical jargon. It is usually written on a physical or digital card that can be easily moved and prioritized2. * Conversation: A user story card is not enough to convey all the information needed to develop and deliver the feature. It is meant to trigger a conversation between the product owner, the development team, and other stakeholders. The conversation is where the details, assumptions, risks, and acceptance criteria are discussed and clarified. The conversation is also an opportunity to collaborate, negotiate, and validate the user story3. * Confirmation: A user story is not complete until it has a confirmation. This is a set of criteria that define what done looks like for the feature. It is also known as acceptance criteria, and it specifies the conditions that must be met for the user story to be accepted by the product owner and the customer. The confirmation is usually written as a series of testable statements that can be verified by the development team and the product owner4. 1: 3 C's of User Stories- Well Explained - KnowledgeHut1; 2: Understanding the three "C"s of agile User Stories - Medium2; 3: 3 C's For Writing User Stories | 3 C's of User Stories - PremierAgile3; 4: 3 C's Of Agile User Stories: A Brief Summary - BarnRaisers, LLC5
Question 54

Correct Answer: A
Question 55
What is the focus of Lean Thinking?
Correct Answer: A
Lean Thinking is a philosophy that aims to create value for customers by eliminating waste and unnecessary steps in company processes. One of the main sources of waste is delay, which can be caused by long lead times, large batch sizes, excessive inventory, poor quality, and lack of coordination. Reducing delays can improve customer satisfaction, increase efficiency, and lower costs. Lean Thinking is based on two pillars: respect for people and continuous improvement. Respect for people means empowering and engaging employees, customers, and stakeholders to participate in problem-solving and innovation. Continuous improvement means constantly seeking ways to improve the process and the product by applying the Plan-Do- Check-Act cycle and the scientific method.
