Exam PMI-ACP topic 1 question 150 discussion

D is best in my opinion. The question sentence of option C "collectively estimate" seems like indicating Affinity estimation but this time we should take it as operational work of Option-D (Planning Porker) in my opinion. Actually, affinity estimation make group based on story size but it might not collectively update the size. So I do go D.

Considering my previous post, I vote D.

Affinity has nothing in common with numbers. The purpose of Affinity is to make sure that stories of similar effort are given the same number of story points.

Planning Poker uses story points. Affinity Estimating can use sizes e.g. small. medium, large. Vote D.

C = wrong. Affinity = grouping stories by similar complexity. D = correct. Planning poker = collectively estimation. It is a consensus-based planning and estimating technique used to assess product backlogs, guessing how much time and effort is needed to complete each of the backlog's initiatives.

Vote D

"using story ponts"

D he agile team is using the relative sizing technique known as Planning Poker when estimating the relative size of its stories using story points. This technique involves each team member independently estimating the size of a story, then discussing and comparing their estimates until a consensus is reached Planning Poker: A Fun and Effective Estimation Technique" by Mike Cohn, published on the Mountain Goat Software website.

Changing my answer to C.

Confused between C & D, I think D is correct.

C for sure Affinity estimating is a technique that involves grouping items into similar categories or collections—i.e., "affinities.” In agile, we can use this technique for many purposes, but one of the most important is to make sure our story point unit remains consistent for all our estimates over the duration of the project.

D sure

D is correct Collective estimates typically use Planning poker as a tool, the team makes a collective estimate by playing an estimation game. https://www.visual-paradigm.com/scrum/what-is-agile-estimation/

What is Planning Poker? Planning poker is also referred to as Agile Poker. It is a group estimation technique often used by agile teams to estimate the amount of effort or relative size of development goals in software development.
