Q

What is the primary purpose of the PO Sync
Who runs it?
How often and how long?

A

PO Sync is a 30 – 60-minute event typically occurring once or twice weekly. The RTE or a Product Manager facilitates PO Sync. Product Management and POs review the ART’s progress toward the PI Objectives and make scope or prioritization adjustments if needed.

Another purpose of PO Sync is to prepare the ART Backlog for the following PI. Feature refinement and weighted shortest job first (WSJF) are done during the PO Sync to prepare for the following PI

** PO Sync is also used to plan for the upcoming PI. It provides the time and venue for Product Management and POs to align on Features, priorities and be one voice. **

Q

What are the five SAFe Basic Agile Quality Practices?
The set of five basic Agile quality practices that can be applied to every business domain.

A
  1. Shift Learning Left: – Reveal problems sooner, take corrective action with minimum impact.
  2. Pairing and Peer Review: Multiple viewpoints enhance work quality and grow knowledge.
  3. Collective Ownership and T-shaped skills: In Collective Ownership individual team members have the requisite skills and authority to update any relevant asset. Collective ownership is supported by quality standards that encourage consistency, enabling everyone to understand and maintain the quality of each component. Collective ownership is further enabled by ‘T-shaped skills.’ T-shaped skills characterize individuals who possess deep experience in one area but also have broad skills in other areas.
  4. Artifact Standards and definition of done: Ensure consistent quality for each work product.
  5. Workflow Automation:

Q

What is Flow metric: Flow Distribution

A

Flow Distribution: Measures the proportion of work items by type in the system at any point in time.

10/1: 20% DRs 20% Enables 60% stories
10/15: 25% DRs 30% Enables 55% stories
11/1: 30% DRs 25% Enables 45% stories

Q

What is ‘Flow Efficiency’ Metric?

A

Flow efficiency measures how much of the overall flow time is spent in value-added work activities vs. waiting

Active time +——+ +—-+ +——–+ +—->
Delay time +–+ +——-+ +—–+
Flow time +————————————————–+

Flow efficiency: Total Active Time/Flow Time

Q

What are the four aspects of Continuous Delivery Pipeline (CDP)?

A

(CE) Continuous Exploration
(CI) Continuous Integration
(CD) Continuous Deployment
Release on Demand

17
Q

What does CE (Continuous Exploration) of the CDP focus on?

A

Continuous Exploration (CE) focuses on creating alignment on what needs to be built.

Design thinking is used to ensure the enterprise understands the market problem / customer need and the solution required to meet that need.
Hypothesis ->
Collaboration/Research ->
Architecutre —>
Synthesize

Architecture: With a clear understanding of the problem, CE moves into the solution space, defining the minimum amount of architecture that will support the Solution and enable continuous delivery.

Synthesize distills the knowledge gained into a new future state for the solution. The vision, roadmap, and prioritized backlog of features align the ART’s teams to a shared direction.

18
Q

What does CI (Continuous Integration) of the CDP focus on?

A

Focuses on taking features from the Program backlog and implementing them.

Completed work is committed to version control, built and integrated into a full system or solution, and tested end-to-end before being validated in a staging environment.

Develop -> Build -> Test -> Stage

19
Q

What does CD (Continuous Deployment) of the CDP focus on?

A

Takes the changes from the staging environment and deploys them to production. At that point, they’re verified and monitored to make sure they are working properly.

Deploy -> Verify -> Monitor ->Respond

20
Q

What does RoD (Release on Demand) of the CDP focus on?

A

The ability to make value available to customers all at once, or in a staggered fashion based on market and business needs.

21
Q

The I&A event consists of three parts. What are they?

A

The I&A event consists of three parts:
- PI System Demo
- Quantitative and qualitative measurement
- Retrospective and problem-solving workshop.

22
Q

The achievement score (Actual Business Value) associated with the PI Objectives are scored when?

A

Durning PI System Demo

23
Q

True or False?

The problems you want to bring to the Problem-Solving workshop are those out of the teams’ control.

A

True

24
Q

What is one of the primary goals of DevOps?
