For accurate project estimates, we use a bottom-up technique. This means that we divide large tasks into smaller parts and determine the time required to complete each part. Then we add up the estimates for all these parts to get the total estimate.Sometimes, for a new project, we take previous similar projects and use their cost and time data to estimate the cost and time for a new project.Our product manager reviews the estimates from the developers and experts and determines an accurate figure.We create a document, formulate a final estimate and send this document to a client.
