Most accurate estimate of project can be obtained by:- a. Analogous Estimating b. Parametric Estimating c. Rough Estimating d. Bottom -up Estimating?

In bottom-up estimating, each task is broken down into smaller components. Then, individual estimates are developed to determine what specifically is needed to meet the requirements of each of these smaller components of the work...

Analogous estimating uses a similar past project to estimate the duration or cost of your current project

Parametric estimating uses the relationship between variables to calculate the cost or duration.

So, anwser would be D...

Option D is the correct answer.

d. Bottom - up estimating

1. Consider simpler or more efficient ways to organise and perform the work
2. Plan and estimate the project rollout from the very beginning so that the rollout won't become a chaotic scramble at the end. For instance, you could propose using a minimally disruptive approach, such as a pilot programme or a phased implementation
3. consider a phase-based approach, where the first phase focuses primarily on requirements gathering and estimating
4. Develop contingency plans
5.  prioritising the deliverables right from the start into "must-have" and "nice-to-have" categories
6. Refer to your lessons-learned database , and incorporate your best practices into future estimates
