The role of the System Architect/Engineer in SAFe is to guide the teams and support the Architectural Runway, which is the existing code, components, and technical infrastructure needed to implement near-term features without excessive redesign and delay. The System Architect/Engineer defines and communicates the technical and architectural vision for the solutions developed by an Agile Release Train (ART), ensuring that they fit the intended purpose and align with the enterprise and solution architecture. The System Architect/Engineer also collaborates with various roles, teams, and stakeholders within and outside the ART to ensure that the system architecture supports the evolving business needs and enables fast and reliable implementation. References: System Architect/Engineering - Scaled Agile Framework, Architectural Runway - Scaled Agile Framework
Question # 42
The Inspect and Adapt event always starts with which activity?
= The Inspect and Adapt event is a significant event held at the end of each PI, where the current state of the Solution is demonstrated and evaluated. Teams then reflect and identify improvement backlog items via a structured problem-solving workshop1. The Inspect and Adapt event always starts with the PI System Demo, which is the first part of the event. The PI System Demo shows all the Features the ART has developed during the PI, and provides an opportunity for feedback from stakeholders and customers2. The PI System Demo is followed by quantitative and qualitative measurement, where the ART reviews the progress and performance of the PI, and evaluates the business value achieved3. The last part of the Inspect and Adapt event is the Retrospective and Problem Solving Workshop, where the ART identifies the root causes of the most critical issues and creates improvement backlog items4. References: = 1: Inspect and Adapt - Scaled Agile Framework1; 2: Inspect and Adapt - Scaled Agile Framework1; 3: Inspect and Adapt - Scaled Agile Framework1; 4: Inspect and Adapt - Scaled Agile Framework1
Question # 43
When should a component team be used?
A.
To develop T-shaped skills together with Continuous Integration
B.
To create each replaceable component with minimized dependencies
C.
To gain the fastest velocity with well defined interfaces
D.
To obtain high reuse and technical specialization with a focus on nonfunctional requirements
A component team is an Agile Team whose primary area of concern is focused on a specific component, or set of components, of the system. They leverage their technical skills and interest and focus on building robust components that provide for reliability, separation of concerns, foster re-use, and improve testability. Component teams are typically used when the system has complex, nonfunctional requirements that require deep technical expertise and specialization, such as performance, security, scalability, etc. Component teams can also enable high reuse of components across multiple solutions, reducing duplication and waste. However, component teams also introduce challenges, such as increased dependencies, coordination, and integration efforts with other teams, as well as reduced end-to-end value delivery and customer feedback. Therefore, component teams should be used sparingly and only when the benefits outweigh the costs. References: Organizing Agile Teams and ARTs: Team Topologies at Scale, Agile Teams, Feature Teams vs Component Teams, System Team, Feature Team vs Component Team in Agile
Question # 44
During which of the following PI Planning activities does Product Management introduce the prioritized Features to the teams for planning?
A.
The Product/Solution Vision presentation
B.
The draft plan review
C.
The business context presentation
D.
The Management Review and Problem-Solving workshop
 The Product/Solution Vision presentation is the PI Planning activity where Product Management introduces the prioritized Features to the teams for planning. This presentation provides the teams with a clear and compelling vision of the expected outcomes and benefits of the upcoming PI. It also includes the top Features and Capabilities that are needed to realize the vision, along with their priorities and dependencies. The teams use this information to plan their Iteration goals and PI objectives, as well as to identify risks and issues that may affect their delivery. References: = PI Planning - Scaled Agile Framework, Exam Study Guide: SP (6.0) - SAFe® Practitioner
Refactoring is the process of improving the design and structure of existing code without changing its external behavior. It is a quality practice for software development because it helps to reduce technical debt, improve maintainability, readability, and testability, and enable faster delivery of value. Refactoring is one of the core engineering practices in SAFe, along with Test-First, Continuous Integration, and Pair Work. References: SAFe for Teams - Know Your Role on an Agile Team, Exam Study Guide: SP (6.0) - SAFe® Practitioner, SAFe for Teams | SAFe Practitioner (SP) Certification, Built-in Quality
Question # 46
What are the three levels of the Scaled Agile Framework?
The three levels of the Scaled Agile Framework are Essential, Large Solution, and Portfolio. These levels represent the different levels of abstraction and complexity involved in delivering value to customers. The Essential level is the foundation of SAFe and includes the Team and Program levels, where agile teams and agile release trains (ARTs) work together to deliver solutions. The Large Solution level is an optional level that supports the coordination and alignment of multiple ARTs and suppliers that build large and complex solutions that require additional roles, events, and artifacts. The Portfolio level is the highest level of SAFe and provides strategic direction, funding, governance, and value stream management for the entire portfolio of solutions. References: SAFe® for Teams - Know Your Role on an Agile Team, Exam Study Guide: SP (6.0) - SAFe® Practitioner, SAFe 5.0 Framework
Question # 47
Why is the modified Fibonacci sequence used when estimating?
A.
It serves as a way to estimate large ranges
B.
It can be used to predict unit test coverage
C.
It results in greater precision
D.
It reflects the uncertainty in estimating larger items
The modified Fibonacci sequence is a series of numbers that starts with 0, 1, 2, 3, 5, 8, 13, 20, 40, 100, and so on. It is used when estimating the relative size and complexity of backlog items, such as stories and features, using story points or normalized estimation. The modified Fibonacci sequence reflects the uncertainty in estimating larger items, as the gap between the numbers increases as the numbers get bigger. This means that the larger the item, the less precise the estimate, and the more likely it is to be split into smaller items. The modified Fibonacci sequence also helps to avoid the false sense of accuracy that comes from using linear scales, such as hours or days, which may not account for the variability and unpredictability of the work. References: Exam Study Guide: SP (6.0) - SAFe® Practitioner, Story, Feature, Estimating
Question # 48
What is the purpose of the Iteration review?
A.
To serve as a forecasting meeting where the work is estimated for the Program Increments
B.
To show the backlog items and work on possible Solutions for the backlog items
C.
To measure the team's progress by showing working Stories to the stakeholders and getting ^ feedback from them
D.
To identify where there is too much work in the system and where the teams are being ^ overloaded
The Iteration Review is a regular SAFe Scrum event where the team inspects the iteration increment, assesses progress, and adjusts the team backlog. The purpose of the Iteration Review is to measure the team’s progress by showing working stories to the Product Owner and other stakeholders to get their feedback. The Iteration Review provides a way to gather immediate, contextual feedback from the team’s stakeholders on a regular cadence. The Iteration Review also allows the team to demonstrate their contributions, receive feedback to improve the solution, and adjust the Team Backlog based on new opportunities. References: Iteration Review, Iteration Review, What is Iteration review in SAFe® 6.0?, Iteration Review65
