' Which of the following estimation techniques can be used to generate an abstract, introductory schedule, or cost estimate? C] Conceptual estimate C] Definitive estimate C] Preliminary estimate C] Single-point estimate a Which of the following tasks is part of the \"manage estimates\" stage? C] Collecting inputs C] Comparing project performance to the baseline estimate C] Identifying constraints C] Gathering up the estimating team a A project manager is approached by an organization to develop the resource planning for their new innovative project. Even though the project manager has worked with many similar organizations in the past, this time, they are skeptical about the project's business model. Should the project manager use historical information in this case? [:1 Yes, since an accurate estimation of resources cannot be performed without referring to historical information. [:1 No, since every project is unique, there is rarely any correlation between different projects' resource expectations. [:1 No, since historical information is usually not applicable for innovative and rapidly changing projects. [:1 Yes, since historical information can provide insight when making comparisons to resources used on previous similar projects a What is the role of a project sponsor in the project estimation process? C] Estimating an activity's resources and duration C] Reviewing and approving the project estimate C] Documenting assumptions and risks C] Collecting all of the estimates Dominique, who is a scrum master, uses planning poker to estimate user stories. After going through the rst user story details, Dominique asked her team members to Choose a card as an estimate of the ideal number of days to complete the user story and then to reveal their cards. Since the estimates were vastly disparate, Dominique instantly asked for reestimation in order to converge team members' estimates. What did Dominique do wrong? 8 C] The team re-estimated immediately after everyone revealed their cards. [:1 Cards shouldn't be revealed. C] Dominique didn't do anything wrong. C] The team used ideal days as the unit for estimates. a During the sprint planning session, a serum team came across a disputahle user story for which everyone had a different story point estimate. The product owner, being the most acquainted with the business case, weighed in with a story point estimate of 2. However, the scrum master thinks it should be 3, comparing it to similar previously completed stories. The crossfunctional team thinks it should be assigned 5 story points. Which estimate should be applied? C] 3, because the project manager has past experience that allows them to use the analogous estimation technique C] 3, as an average of all estimates C] 2, because the product owner is the most aware of the business C] 5, because the team members are the ones who will be working on the story 7 A project manager is planning for a project consisting of manufacturing a drone for wildlife protection purposes. The project is challenging because the drone is supposed to be able to identify and keep count of a wide range of wild animals. Since they have previously dealt with drones in the military field, the project manager thinks that using analogous estimating will be of great help for their current project. This estimation technique is best known as O Parametric estimating Bottom-up estimating O Expert judgment estimating O Three-point estimating 18 The accuracy of a definitive estimate ranges between: O -20% and +25% 0 -5% and +10% 0 -15% and +20% O -10% and +15%A project manager is managing an industrial project using a hybrid approach. The project team has estimated that a work package will most likely require 5 days to complete. If everything goes well, it could take only 3 days. However, in the worstcase scenario, it might take up to 13 days to complete. So, the team has decided to opt for the PERT method to set a nal estimate. What is the expected duration of the work package using the PERT method? D 6 days [3 5 days [3 8 days [3 7 days a Which of the following is NOT part of the threerpoint estimation formula? C] Pessimistic C] Mostlikely C] Optimistic C] Leastlikely
