Final answer:
The project team can utilize Analogous estimating, Expert judgment, and PERT as methods to estimate the likely number of work periods required for an activity. Each method leverages historical data, expertise, or statistical analysis to provide an estimation.
Step-by-step explanation:
The project team can estimate the likely number of work periods required to perform an activity using various methods. Analogous estimating involves using the actual duration of previous, similar projects as the basis for estimating the duration of the current project. This method relies on historical data.
Expert judgment is another approach where individuals or groups with specialized knowledge or training in a particular area provide insight that could influence the estimation. This often involves consultation with experts who have experience with similar projects.
Lastly, the Program Evaluation and Review Technique (PERT) is a statistical tool used to plan and control large construction projects. It requires the project team to calculate optimistic, pessimistic, and most likely duration estimates to find the weighted average. This can provide a more nuanced estimation than other methods.
