A new project needs to be submitted for urgent funding approval. The project, which will use a new technology, is vital to the organization. The entire Scrum team has worked together for over 3 years on multiple projects and delivered the previous project under the approved budget.Which estimation technique should the project manager implement in this context?

Order of magnitude estimation is a rough approximation used primarily in the early stages of project planning to gauge potential costs or timeframes. Given the established teamwork and the urgency for precise funding approval in this scenario, such a vague technique would not meet the project's specific needs for accuracy and detail.

Definitive estimates provide a high level of accuracy and are typically utilized later in the project cycle when detailed information is available. In this context, where the project is urgent and relies on agile methodologies, a definitive estimate may not be practical or necessary, as it could delay the approval process.

Budget estimates focus on the financial aspects of a project and may not fully capture the complexities of task execution. While important, they do not align with the agile approach of Scrum, which emphasizes delivering functional increments of work rather than strictly managing budgetary constraints upfront.
