Let’s look into some of the activity estimation technique in this PMI PMP project management tutorial here.
First is activity estimation technique is ,Analogous Estimating.
– This technique used for estimating the duration or cost of an activity or a project using historical data from a similar activity or project.
– This is used to estimate project duration when there is a limited amount of detailed information about the project is available but is less accurate.
example.
If the last 5 similar projects took 6 months,this one will also take 6 months.
Next project activity estimation technique is,Parametric Estimating.
– This uses a mathematical model to calculate projected times for an activity based on historical records from the previous projects and other information.

example.
if the assigned resource is capable of installing 100 meters of cable per hour ,the duration required to install 2,500 meters is 25 hours.
