## Which of the following techniques can you use to estimate the duration of an activity?

**You have four techniques to calculate activity duration in project management:**

- Analogous Estimating.
- Parametric Estimating.
- Three-Points Estimating.
- Bottom-up Estimating.

## How do project managers estimate task duration?

Work within a range (three point estimate)

Then, add the times for the best and worst cases plus four times the most likely. **Divide by six**. This gives you an estimated duration which takes into account the uncertainties of the estimate but weighs the result more strongly towards the most probable result.

## What are the different estimation techniques for project activities?

**Major project estimation techniques**

- Top-down estimate. …
- Bottom-up estimate. …
- Expert judgment. …
- Comparative or analogous estimation. …
- Parametric model estimating. …
- Three-point estimating.

## What estimation technique does the project Manager use?

While accurate estimates are the basis of sound project planning, there are many techniques used as project management best practices in estimation as **– Analogous estimation**, Parametric estimation, Delphi method, 3 Point Estimate, Expert Judgment, Published Data Estimates, Vendor Bid Analysis, Reserve Analysis, Bottom- …

## What are the duration estimating techniques?

**They are as follows:**

- Analogous Estimating. This is a very important methodology that gives you the entire duration estimation. …
- Parametric Estimating. This method is more accurate in nature. …
- Three-Point Estimating. …
- Heuristic Estimating. …
- Reserve Analysis. …
- Conclusion.

## How do you estimate project duration?

If everyone worked eight hours per day on your project, and was absolutely 100% productive for all eight hours, you could easily calculate duration by **taking the number of effort hours, divided by the number of resources, divided by the number of hours they work per day**.
