Backlog Management Flashcards

What is the 'cone of uncertainty' as it applies to backlog estimation?

Answer: The idea that estimates become more accurate as work is better understood over time

The cone of uncertainty shows that estimation accuracy improves as requirements are clarified and more is known about the work ahead.

How does relative estimation differ from absolute estimation in backlog management?

Answer: Relative estimation compares items to each other; absolute assigns specific time values

Relative estimation (e.g., story points) compares the complexity of items against each other, while absolute estimation assigns specific durations like hours or days.

What is the risk of over-detailing backlog items too far in advance?

Answer: Requirements may change, making detailed work obsolete and wasteful

Detailed work done on items far in the backlog may be wasted if priorities shift or requirements evolve before they are developed.

What is a 'spike' in a product backlog?

Answer: A time-boxed research task to reduce uncertainty before committing to work

A spike is a time-boxed investigation or research activity used to gather information and reduce the uncertainty around a complex backlog item.

How should a Product Owner balance technical debt items against new feature work in the backlog?

Answer: Allocate a percentage of each sprint capacity to technical debt items

Reserving a consistent portion of sprint capacity for technical debt prevents it from accumulating to a point where it impedes new development.

What is the purpose of a 'minimum marketable feature' (MMF) concept in backlog management?

Answer: To define the smallest set of functionality that delivers value to users

An MMF is the smallest feature set that can be released and still provide meaningful value to customers, enabling faster time to market.
