#### 2.3.2 Pareto Analysis  
Pareto Analysis, a statistical technique in decision-making, is based on the Pareto Principle, which posits that 80% of the effects come from 20% of the causes for many events, as displayed in Table 3. This method is integral to identifying the most significant factors in a set of data, which, in the context of BIM execution plans, helps prioritize standardization efforts. By focusing on the few critical elements that cause the most significant impact, researchers and practitioners can streamline processes, optimize resource allocation, and drive substantial improvements in project outcomes [17]. \begin{table}
\begin{tabular}{l l l l l} \hline \hline  & **Sub-Elements** & **Number of Sub-Elements** & **Percentage** & **Percent 80\%** \\ \hline

Table 3: Pareto analysis of BEP sub-elements by frequency and impact. Figure 4: The percentage of occurrence of the sub-element’s topics in the reviewed document. The Pareto analysis displays the number and relative importance of sub-elements within BIM execution plans. The blue bars indicate the number of occurrences of each sub-element in the reviewed documents, while the orange line charts the cumulative percentage, highlighting that a small number of sub-elements account for a large percentage of the focus in BIM documentation. This analysis is a strategic tool for identifying critical areas for standardization and improvement. In the Pareto analysis figure, the sub-elements that surpass the 80% (BIM Use, BIM Model and Level of Development, Project information, Model Coordination, and Project Goals and Objective) threshold are of particular significance as they comprise the core content within the BIM execution plans. These critical elements are the main contributors to the substance of the documentation, representing most of what is deemed essential in literature. Identifying these allows for focused improvements in areas that will yield the most substantial impact on the standardization of BIM execution plans. The proposed framework, which requires validation through a literature review, is based on the results and analysis of the provided data in Table 4.
