QUESTION: 49

Which two statements describe the purpose of value stream mapping? (Choose two.) Choose the correct option from below list

To deliver incremental value in the form of working, tested software and systemscorrect
To create an understanding of the budget
To create an action plan for continuos improvement
To understand the Product Owner's priorities
To visualize how value flows

Answer(s): A,E

Explanation:

The purpose of value stream mapping is to visualize how value flows from concept to cash and to deliver incremental value in the form of working, tested software and systems. Value stream mapping helps to identify the current state of the value stream, the steps, activities, roles, and tools involved, and the delays, waste, and inefficiencies that can be eliminated or improved. It also helps to create a future state vision and an action plan for continuous improvement

Weighted shortest job first is applied to backlogs to identify what? Choose the correct option from below list

Maximum economic value
Epics, Features, and Capabilities
User business value
Proxy for job size

Answer(s): A

Explanation:

Weighted Shortest Job First (WSJF) is a prioritization model used to sequence work for maximum economic benefit. In SAFe, WSJF is estimated as the relative cost of delay divided by the relative job duration. In a flow-based system, priorities must be continuously updated to provide the best economic outcomes. In other words, job sequencing produces the best results rather than prioritization based on a theoretical return on investment for each job. To that end, SAFe applies WSJF to prioritize backlogs. Backlogs are continuously prioritized based on a WSJF algorithm that uses relative user and business value, time criticality, risk reduction and/or opportunity enablement, and job size. WSJF also conveniently and automatically ignores sunk costs, a fundamental principle of Lean economics

QUESTION: 51

What differentiates Deployment and Release in the continuous Delivery Pipeline? Choose the correct option from below list

Deployment occurs multiple times per day; release occurs on demand
Deployment occurs multiple times per day; release occurs in PI boundaries
Deployment involves moving changes to staging; release involves moving them to productionwrong
Deployment involves moving changes to production; release involves making them available to end users

Answer(s): D

Explanation:

Continuous Deployment (CD) is an aspect of the Continuous Delivery Pipeline that automates the migration of new functionality from a staging environment to production, where it is made available for release. CD is a technical practice that enables the ability to release value at any time, in a sustainable way. CD is not the same as Release on Demand, which is the business decision to make the new functionality available to end users. Release on Demand is the final aspect of the Continuous Delivery Pipeline, which enables the delivery of value to the end user as fast as possible, based on market demand

QUESTION: 52

How should developers integrate refactoring into their workflow? Choose the correct option from below list

Refactor continuously as part of test-driven development
Allocate a portion of their capacity to refactoring in every Iteration
Create and estimate refactoring Stories in the Team Backlog
Create and estimate refactoring tasks for each Story in the Team Backlog

Answer(s): C

Explanation:

Refactoring is the activity of improving the internal structure or operation of a code or component without changing its external behavior. The goal of software development is the continuous delivery of business value to users and stakeholders. Constantly changing technology and evolving business objectives make maintaining and continuously increasing business value difficult. Refactoring enables an emergent design, ensuring the system continues to meet future business needs. Refactors are a particular type of Enabler story in SAFe, and, like any other Story, they must be estimable, verifiable, and valuable, as well as accepted by the Product Owner. SAFe emphasizes the importance of keeping all work visible, including refactoring. Like user value work, refactoring must be planned for, estimated, and prioritized. Therefore, developers should create and estimate refactoring Stories in the Team Backlog, and work on them according to their WSJF1
