### Functional Acceptance and Evaluation of Cockpit4.0+ Prototype  
The OS-PT sector, a cornerstone of Portugal's rich cultural heritage and forward-looking innovation, has significantly contributed to iconic stone monuments worldwide since the 15 th century [53]. Recent data from the Portuguese Stone Federation (2022) illuminate the sector's substantial economic impact: exporting to 116 countries, ranking as the ninth most significant player in the World International Stone Trade, and securing the second position globally regarding international trade per capita [54]. With exports outstripping imports by 660% and a significant share of exports reaching markets outside Europe, the industry boasts a turnover of EUR 1.230 million. It supports over 16,600 direct jobs, making it a critical employment source, particularly in inland regions [55]. A preliminary evaluation involved technical experts and engineers from 24 OS-PT SMEs. These SMEs were strategically selected to represent a wide range of digital maturity levels within the OS-PT sector, thus providing a diverse and representative sample for the evaluation. This approach yielded valuable insights into accepting the Cockpit4.0+ prototype's functionalities across various stages of digital readiness among the SMEs involved. For the study, each participating company was assigned a digital level (DL) based on comprehensive site visits, categorized as follows: DL#0: no digital tools are used; DL#1: at least one computerized machine on the manufacturing shop floor; DL#2: all machines are computerized; DL#3: all machines are computerized and connected to the ERP system; and DL#4: all machines are connected to the ERP system and can connect to Building Information Modeling (BIM) architects' stations. The evaluation included a detailed assessment of each company's digital production equipment, management, integration processes with production, and involvement in digital marketplaces. The survey was structured into four actions. First Action (Introduction): Highlighting the shift towards BIM and the upcoming need for stone companies to adapt to BIM-shaped procurement in the Architecture, Engineering, and Construction (AEC) market, with a tangible demonstration of the Cockpit interface. Second Action (Explanation): Explanation of the Cockpit's functionalities regarding innovation, usefulness, cybersecurity, and usability in facilitating coopetition among rival SMEs, including features for resource sharing without prior partner knowledge, maintaining commercial confidentiality, and automated resource allocation based on buyer decisions. Third Action (Questions): Participants were asked to rate, on a scale from one to five, their opinion on Cockpit4.0+ regarding technological disruptiveness, usefulness, cybersecurity, and usability. Fourth Action (Data Collection): The survey was conducted throughout 2023, with the data anonymized to maintain confidentiality and documented in an Excel file. Average responses are detailed in Table 2.  
The aggregated ratings from respondents underscored the perceived innovation of the Cockpit4.0+ system, with an impressive average score of 3.9 out of 5. This highlights the prototype's potential functional efficacy within the sector. Notably, the perceived usefulness of the system exhibited a positive correlation with the companies' digital maturity. Among the most digitally advanced respondents (DL#4), the system achieved high scores, averaging 4.8 out of 5. Even though cybersecurity emerged as an area for improvement, with an average rating of 3.3 out of 5, the prototype demonstrated significant promise as a tool for enabling coopetition, especially among SMEs with higher digital levels. Converting the quantitative data from the questionnaire into percentages reveals an overall positive acceptance rate of 78.9% for the Cockpit4.0+ prototype, demonstrating its considerable potential to foster coopetition within SME networks (Figure 3).
