Before finalizing the budget, the manager asked for a quick ballpark estimation to determine if the project was feasible.

The engineering team used a Fermi estimate to quickly determine whether the proposed design was feasible.

After discovering new requirements, the engineering team scheduled a re-estimation to update the timeline.

The project manager requested several re-estimations after scope changes were approved.

Before we start the renovation, the contractor gave us a few ball park estimations to help with budgeting.

Before we start the renovation, could you give me a ball-park estimate for the cost?

Before we commit to the renovation, the contractor gave us a ball park estimate to budget for the work.

To analyze correlated longitudinal data from repeated measures, the researchers applied a generalized estimating equation to account for within-subject correlation.

We used a ball-park estimation to budget for the project before obtaining detailed quotes.

At the planning meeting, several ball-park estimations were offered to help prioritize tasks.
