Q

What happens if there are problems/issues in Scrum methodology?

A

Q

What is the difference between Agile vs Iterative vs Incremental?

A

Agile = Multiple deliveries

Iterative = Concerned with the correctness of the solution so there is only a single delivery upon release

Incremental = Multiple/mini bundles of deliverables that are repeated, but there is a specific threshold that needs to be hit to go-live/get ROI

Coach others

53
Is agile based on defined processes or empirical processes?
Empirical - We are using our learned KNOWLEDGE WORK to define future precision
54
What is the most important component to measure in a Predictive life cycle?
Cost - because the product is not valuable until it is DONE
55
Who conducts the sprint review?
The sprint team (not the SCRUM master, not the product owner)
56
What is the difference between the product backlog and the sprint backlog?
The product backlog is dynamic; the sprint backlog is agreed to once the sprint is started and doesn't change. ** The product backlog doesn't have to be complete in order for the sprint backlog to be finalized for a specific sprint

2-4 weeks, no longer than 1 calendar month
58

The Product Owner is not responsible for choosing what user stories go into the sprint because they have already done the pre-work to prioritize the product backlog. They are not MANAGED by the Scrum master.
60
What happens in a Sprint Review if key stakeholders want to see adjustments?
Product Owner and Scrum Master can submit a change request and it will be integrated into the Product Backlog (not the Sprint Backlog)
61
What is the only requirement of things presented at the Sprint Review?
They have to be completely done (meet the DoD)
62

Servant Leadership - carrying food and water, helping team members follow process and get things done but not managing them directly. Helping address NEEDS to ensure the team gets OPTIMIZED team performance Emergent Leadership - Scrum master should focus on getting out of the way and empowerment of anyone stepping up (aligns with the team being self-organized)
66
What is the difference between Outsourced and Distributed Scrum teams?
Outsourced refers to procurement & multiple legal entities in contracting Distributed means people are in different geographic/physical locations
67

Insulates the team from stakeholders wanting early reviews (prior to the Sprint review) Removes other impediments that can get in the way of the Scrum methodology

Distributed amongst the team - there is not a central PM and the Scrum master doesn't really act as a PM, more like a methodology manager
