### Functional Acceptance and Evaluation of Cockpit4.0+ Prototype
The feedback particularly underscores the exceptional value of the system for entities at the forefront of digital integration. However, a focused review and the enhancement of the system's security features are advisable, given the cybersecurity concerns. Strengthening these aspects will bolster confidence in the prototype and enhance its overall utility and acceptance among SMEs. The positive preliminary functional evaluation of Cockpit4.0+, especially by the DL#4 respondents, created solid conditions for the next step: conducting the first experimental test. However, the lower acceptance rates among respondents with lower digital levels (DL#0, DL#1, and DL#2) suggest that these companies are not yet prepared to integrate collaborative software like Cockpit4.0+. This integration requires a digital mindset and needs to be improved in these less digitally mature enterprises. Using the Cockpit4.0+ prototype, a strategic implementation of an experimental pilot test began for the first objective evaluation of Cockpit4.0+. Two companies from the DL#4 group, which rated Cockpit4.0+ the highest in functional acceptance, were formally invited to participate in this pilot test (Figure 4). These two companies, recognized as leaders in the Portuguese stone sector, have all their machines connected to the ERP system, which connects to BIM architects' stations. This setup represents the OS-PT sector's current best practices (CB.Ps). A comprehensive confidentiality agreement was drafted to protect sensitive information regarding the companies' operations, clientele, employees, resources, and competitors. \begin{table}

Figure 3: Evaluation of Cockpit4.0+ by SMEs in the stone manufacturing sector. As BIM integrates the crucial aspect of time, marking a significant evolution in project management and coordination within the construction industry [56], stone fabricators must enhance their scheduling, coordination, and productivity processes to respond to BIM-shaped industry demands effectively. Therefore, \"On-Time Delivery KPI\" was selected as the key performance indicator (KPIOD) for evaluating stone fabricators' responses, reflecting their ability to meet project deadlines (Equation (1)) consistently. \[\text{KPI}_{\text{OJD}}\left(\%\right)=\sum_{1}^{n}\left(\frac{\textit{parts \_delivered\_on\_time}_{(daily)}}{\sum\textit{parts\_delivered})_{(daily)}}\right) \tag{1}\]  
Improvements in KPIOD directly enhance the effectiveness of ensuring timely project execution and schedule adherence. This study employed a data collection strategy across two fifty-four-day intervals to explore the transition from CB.Ps to cooperative network practices (CN.Ps) enhanced by Cockpit4.0+, enabling a robust comparative analysis of on-time delivery outcomes. CB.P phase: The first interval focused on capturing standard operations at the two anonymized companies. This baseline phase documented each company's reliance on internal resources for production and delivery, providing essential reference data for subsequent comparisons. CN.P phase: The second interval assessed the effects of integrating these entities into a coopetition-based network enhanced by the Cockpit4.0+ prototype. Data management and privacy were rigorously maintained throughout the study in compliance with confidentiality agreements.
