product that is being developed. It should explain how the product differs from competing
products.
What fundamental questions should be answered in a product vision? correct answers What is
the product that is proposed? Who are the target customers and users? Why should customers
buy this product?
List the principal information sources that may be used in developing a product vision. correct
answers Domain experience, product experience, Customer experience, prototyping and 'playing
around'.
What is software product management? correct answers Software product management is a

Product manag-ers (PMs) take overall responsibility for the product and are involved in
planning, development, and marketing.
What factors must be considered by software product managers when they are doing their job?
correct answers Business needs, technology constraints, customer experience.
What is a product roadmap? correct answers A plan for the development, release and marketing

, Why is it important to develop a prototype as the first stage of product development? correct
answers To check what you want to do is feasible and to demonstrate the software to prospective
customers and company funders.
What are the three main objectives of agile software engineering? correct answers Deliver
functionality quickly, respond quickly to changing product specifications, minimize development
overheads.
What is incremental development and delivery? correct answers The development and delivery
of a software product in discrete stages where, in each stage, some of the product features are
implemented and tested.
List five agile development principles. correct answers Involve the customer, embrace change,
develop and deliver incrementally, maintain simplicity, focus on people not process.
What are the most widely adopted Extreme Programming practices? correct answers Incremental
planning/user stories, Small releases, test-driven development, continuous integration,
refactoring.
How are XP teams managed? correct answers Management is a collective team activity, with no
designated project manager.
What is Scrum? correct answers Scrum is a framework for agile project organization.
What is the principal responsibility of the Product Owner in a Scrum team. correct answers The

product that they are building rather than diverted into less relevant technically interesting work.
What is a 'potentially shippable product increment'? correct answers A code increment that is of
product-quality i.e. the code has been completely tested, reviewed and documented.
List five benefits of using Scrum. correct answers Unstable requirements don't hold up progress,
stakeholders can relate to product increments, customers see on-time delivery of increments,
team communication is improved, trust is established between developers and customers.
What are the principal product backlog activities in Scrum? correct answers Refinement,
estimation, creation, prioritization.
What factors should be taken into account when deciding how many story points are required to
complete a backlog item. correct answers The size of the task, its complexity. the technology
required and the unknown characteristics of the work.
