During a project involving the development of a new software application, the project management team is utilizing story points to estimate the effort required for user stories. They have already established a baseline through comparative analysis with similar past projects. When planning the upcoming sprint, the team encounters a user story that encompasses the development of a complex new feature which has not been implemented in any of the previous projects. What should the team do to estimate this user story's effort accurately?
Assign the lowest story points to minimize the risk of schedule overruns.
Conduct a planning poker session with the team to collectively estimate the effort.
Rely on the technical lead's estimate since they have the most experience.
Quote the story points based on the average effort of similar tasks from past projects.
