Project Estimation and Critical Path Management

Kanami is managing a project with a high degree of uncertainty. Which estimating approach would be most suitable and defensible for her to use?

• Bottom-up estimating

• Parametric estimating

• Three-point estimating

• Top-down estimating

Saori discovers that a project has a negative cost variance. What does this typically indicate, and what is the implication for project recovery?

• The project is under budget and easy to recover.

• The project is over budget and recovery may be difficult.

• The project is on schedule and requires no action.

• The project's earned value is less than the actual cost.

Joseph is tasked with estimating a new software development project. He chooses to break down the project into coding, testing, and documentation, estimating each separately. What type of estimating is Joseph employing, and what is its primary advantage in this context?

• Bottom-up estimating; increased accuracy through detailed analysis

• Top-down estimating; speed and efficiency in initial phases

• Analogous estimating; leveraging historical data for quick results

• Parametric estimating; using statistical relationships for estimation

Ana is using the Critical Path Method. Why is identifying the critical path crucial for effective project management?

• It helps in allocating resources evenly across all tasks.

• It simplifies communication with stakeholders.

• It determines the shortest possible project duration and highlights tasks that, if delayed, will delay the entire project.

• It allows for easy cost estimation.

Ester is estimating a project and chooses to involve several experienced team members and stakeholders. Why is this considered a good practice in project estimation?

• To reduce the time spent on estimation.

• To increase accuracy and reduce bias by incorporating diverse perspectives.

• To avoid the need for risk assessment.

• To ensure all estimates are optimistic.

Nayeon is using three-point estimating. How does this technique enhance the reliability of project estimates?

• By focusing solely on the most likely estimate to save time.

• By only considering optimistic and pessimistic scenarios.

• By weighing optimistic, pessimistic, and most likely estimates to account for uncertainty.

• By removing the need for expert judgment.

Xenia is managing a project with a fixed-price contract. Which estimating method is most appropriate and why?

• Top-down estimating, because it's quicker.

• Bottom-up estimating, because it provides detailed cost justification.

• Analogous estimating, to match historical prices.

• Three-point estimating, to negotiate the price range.

Leonardo is creating a project estimate and decides not to include any buffers for unexpected delays. What is the rationale behind this decision?

• Buffers should always be included to ensure project success.

• Risks should be assessed and managed separately from the initial estimate.

• Buffers make the estimate too conservative.

• Buffers are only necessary for bottom-up estimates.

Kazuki is using the analogous estimating technique. What is the fundamental assumption of this technique, and what is its primary limitation?

• It assumes all projects are unique; limited by the need for expert judgment.

• It assumes historical data is relevant; limited by potential differences between projects.

• It assumes linear project progression; limited by computational complexity.

• It assumes no risks will occur; limited by its reliance on mathematical models.

Santiago is managing a project where the customer demands a detailed breakdown of costs. Which estimation method should Santiago prioritize, and why?

• Top-down estimation, for its simplicity and speed.

• Bottom-up estimation, to provide a detailed cost breakdown.

• Analogous estimation, to compare with past project costs.

• Parametric estimation, to calculate costs based on parameters.
