Good conditions for top-down estimating are when there is high uncertainty involved in the project, when the project is small and internal, when the scope is unstable and when it involves strategic decision making. Which of the following is a good condition for top-down estimating?
The more detailed the estimate is the more the estimate will cost to create The salary of the project manager would be an example of what type of cost found in a project? A. Direct costs.
Top-down methods (sometimes called parametric) usually use ratios, or surrogates, to estimate project times or costs. Top-down approaches are often used in the concept or "need" phase of a project to get an initial duration and cost estimate for the project.
Factors that need to be considered to improve the quality of estimates are the planning horizon, the project duration, the people responsible for making the estimates, project management structure and organization, padding estimates, and the organizational culture.

What is the relationship between organizational culture and estimating? Cultural norms affect the accuracy of estimates. Ed is looking over the actual results of projects and comparing them to what was estimated.
Bottom up estimating is considered by the authors to be more accurate than top down because... It considers specific tasks. Which are project factors that would tend to require a greater level of detail in a work breakdown structure (WBS) used for estimating? A need for tight budget or time control.
In which of the following ways is estimating effort different from estimating time? Effort estimates focus more on the labor required to complete project work.

Typical costs found in a project include direct costs , which consist of labor, materials and equipment, direct project overhead costs and general and administrative overhead costs . Typical kinds of costs found in a project include all of the following EXCEPT. A.
Interaction costs are hidden in estimates. According to the guidelines, each task estimate is supposed to be done independently. However, tasks are rarely completed in a vacuum. Work on one task is dependent upon prior tasks, and the hand-offs between tasks require time and attention.
But past experiences must almost always be refined to reach an acceptable level of accuracy. A good starting point for developing time and cost estimates is.
Resource shortages, whether in the form of people, equipment, or materials, can extend original estimates. Refining estimates may be necessary for a number of reasons. For example, resource shortages, in the form of people, equipment, or materials, can extend original estimates. This is a good example of. A.
The Top-down approach is practical for the initial stage of strategic decision-making and in situations where the information required to develop accurate duration and costs estimates is not available in the initial phase of the project.
The Bottom-up approach is typically more reliable and preferred for estimating because it assesses each work package from the bottom, working up to a deliverable and phase. It is practical to use when project schedules and budget from previous similar projects are available for reference.
