Ray is a project manager in his organization and he’s leading a Scrum-based project. In this project, Ray needs to define with the project team how long each project iteration should take. What term best describes the duration of an iteration in a Scrum project?
- Rolling wave planning
- Timeboxed period(Correct)
ExplanationWhen using an adaptive life cycle, the time-boxed periods for releases, waves, and iterations are specified. Time-boxed periods are durations during which the team works steadily toward completion of a goal. Time-boxing helps to minimize scope creep as it forces the teams to process essential features first, then other features when time permits.

John is the project manager for his organization, and he’s working with the project team to create a project cost estimate. John would like to purchase resources for his project from a specific vendor, The JH Goods Company, that he has worked with in the past. John knows that some other vendors may charge slightly less than the JH Goods Company, but he knows this vendor is reliable and does excellent work. What is the best term to describe John’s preference in this scenario?
- Preferred vendor(Incorrect)
- Sole source
- Single source(Correct)
ExplanationThis is a single source model of procurement. John prefers to purchase from one specific vendor, though there are multiple vendors available. A sole source means only one vendor exists that can fulfill the particular project purchase. Oligopoly describes the market condition that is so tight that the actions of one company affect the operations of others, such as the cost of airline travel or fuel. A preferred vendor isn’t a valid project management term.

Alice is the project manager for her organization and she is considering building a solution for her company. If she builds the solution it will cost the organization $650,000 to create and $17,300 per month to support. A vendor promises that they can build the solution for $120,000, but the monthly fee will be $21,400. What should Alice do?
- Buy the solution if the organization will use the solution for less than 13 months, but more than 11 months.
- Build the solution if the organization will use the solution for longer than 13 months, but less than 24 months.
- Buy the solution.(Correct)
- Build the solution if the organization will use the solution for less than 18 months, but longer than 12 months.
ExplanationAlice should buy the solution as it is incredibly more cost-effective than her in-house solution. It will take 129 months, nearly 11 years, for her solution to be more cost-effective than the vendor’s solution. You can find this answer by subtracting the buy costs from the build costs, which is $650,000 – $120,000 for a difference of $530,000. Then you find the difference of the monthly support costs, which is 21,400-17,300 and equals $4,100. Then you’ll divide the monthly difference into the out-of-pocket costs: 530,000/4,100 for a solution of 129 months. This means in 129 months the in-house solution is more cost-effective than the vendor’s solution.
