Final answer:
A project manager should utilize historical data, expert consultations, organizational assets, and project management tools for detailed activity duration estimates. A timeline helps in visualizing and analyzing relationships between variables. After estimation, it's crucial to review outcomes against estimations to identify and understand any discrepancies.
Step-by-step explanation:
To find the most detailed information for estimating the durations of activities, a project manager should look at historically sourced data whenever it's available, access expertise through subject matter experts, consult organizational process assets, and use project management tools that might include PERT charts, critical path analysis, or Gantt charts. First, it's crucial to analyse the problem and identify the information provided. Drawing a timeline can visually aid the estimation process.
Once you have analyzed the problem, it's important to think about how different variables might be related to each other to help estimate durations more accurately. Utilizing strategies such as analogy estimation, expert judgment, and parametric estimation can also be beneficial. Additionally, refer to the Schedule of Work for specific dates concerning availability and due dates, allowing for better planning and timing estimates for activities.
After implementing the estimations, it's essential to draw a conclusion and analyze whether the actual results support your estimated times. If there are any unexpected outcomes, it is necessary to discuss which events may have contributed to deviations from the calculated times.
