Project Cost Planning
Published in Davies A. Igberaese, Introduction to Project Management, 2023
The cost estimating process needs the involvement of project team members for more accurate results and for greater team commitment. Any of the group decision-making techniques such as brainstorming sessions or the Delphi Technique presents a useful platform for engaging team members in the process. Besides giving the technical information that would enhance the credibility of the estimates, the involvement of team members in the process also increases their commitment to the resulting estimates. In the same vein, the analysis of bids from vendors is another avenue to enhance the outcome of the cost estimating process, particularly for the aspects of the project that are specialist works.

Organizations increasingly use groups and/or teams in their decision-making processes. Group members jointly possess different skills, knowledge, and experience, provide a more in- depth look into the problems, and offer more complete solutions by generating and evaluating more alternatives. The group decision-making process takes longer and sometimes suffers from groupthink, in which some members withhold their opposing views in order to avoid contention in the group. Nominal Group and Delphi Techniques are widely used group decision-making methods.

Among the questionnaires’ respondents, 45% were aged between 35 to 40 years of age, 30% were 25 to 30 years. 15% were more than 40 years, 5% were 30 to 35 years, and the remaining 5% did not provide age details. Among the respondents, 55% were male and the remaining 45% were female. A group of 20 energy experts was consulted through video conferencing and telephonic interviews to establish the pandemic factors responsible for residential energy usage. Once all responses from the interviews were collected, a comprehensive list of factors was shortlisted through Delphi technique; it is given in Table 3. The Delphi method is a group decision-making technique. In MCDM problem solving, the Delphi method is used because it is a structured way of attaining consensus from experts with a controlled feedback method through questionnaires (Bathrinath et al. 2020). The Delphi technique is widely accepted and commonly used in MCDM methods to obtain decision making in expert panels because of its anonymity, group response, and controlled feedback (Qarnain, Muthuvel, and Bathrinath 2020c; Qarnain et al. 2020b). Because there were 34 factors identified, analyzing each factor separately without a theme would confuse readers. Therefore, to make the analysis more helpful, the comprehensive list of 34 factors was classified through a thematic analysis and arranged in terms of 6 themes. All the themes are arranged as main factors; other sub factors to the main factors are provided in Table 3.
Group-based Pythagorean fuzzy soft sets with medical decision-making applications

The influential continuum that ensures the most convenient solution to real-life decision-making scripts by considering and combining the expert ideas of more than one person on a problem is called Group Decision-Making. The collective view of a group of experts in the decision-making continuum improves the reliability of outcomes. Group decision-making is an operation in which more than one person interacts meanwhile, examines problems, appreciates the likely existing options, characterised by more than one conflicting criteria, and selects an appropriate option solution to the problem.

Due to the intrinsic characteristics of group decision-making processes, when involving more than one individual with the respective views and values, the decision-making process must be well structured in order to deliver effective decision-making. For the criteria and alternatives to be well presented, a training on the methodology and the AHP method was carried out. The general operational context of the plant was discussed, and the present approach was proposed. Figure 8 presents the flow of activities developed in this case study.
