Suggested Answer: DCA 🗳️
Delphi technique, expert judgment, and function point analysis are used as a cost estimating technique during the project planning stage. Delphi is a technique to identify potential risk. In this technique, the responses are gathered via a questionnaire from different experts and their inputs are organized according to their contents. The collected responses are sent back to these experts for further input, addition, and comments. The final list of risks in the project is prepared after that. The participants in this technique are anonymous and therefore it helps prevent a person from unduly influencing the others in the group. The Delphi technique helps in reaching the consensus quickly. Expert judgment is a technique based on a set of criteria that has been acquired in a specific knowledge area or product area. It is obtained when the project manager or project team requires specialized knowledge that they do not possess. Expert judgment involves people most familiar with the work of creating estimates. Preferably, the project team member who will be doing the task should complete the estimates. Expert judgment is applied when performing administrative closure activities, and experts should ensure the project or phase closure is performed to the appropriate standards.
A function point is a unit of measurement to express the amount of business functionality an information system provides to a user. Function points are the units of measure used by the IFPUG Functional Size Measurement Method. The IFPUG FSM Method is an ISO recognized software metric to size an information system based on the functionality that is perceived by the user of the information system, independent of the technology used to implement the information system.
Answer option B is incorrect. A PERT chart is a project management tool used to schedule, organize, and coordinate tasks within a project. PERT stands for
Program Evaluation Review Technique, a methodology developed by the U.S. Navy in the 1950s to manage the Polaris submarine missile program. A PERT chart presents a graphic illustration of a project as a network diagram consisting of numbered nodes (either circles or rectangles) representing events, or milestones in the project linked by labeled vectors (directional lines) representing tasks in the project. The direction of the arrows on the lines indicates the sequence of tasks.
