Overview of the Study
The article âProcess View to Innovate the Management of the Social Housing System: A Multiple Case Studyâ is published in the openâaccess journal Sustainability (ISSN 2071â1050). The research was conducted by Giovanna Mangialardi, Angelo Corallo, Mariangela Lazoi and Barbara Scozzi, all affiliated with Italian universities and research institutes specializing in civil engineering, architecture and public administration. The paper presents a multipleâcase investigation of five regional public agencies (ARCA) that manage social housing in the Apulia region of Italy.
Research Aim and Methodology
The authors aim to understand the âproblematic situationâ affecting the agencies and to propose innovative processâbased solutions. They adopt process theory combined with ambidextrous Business Process Management (BPM) and perform data collection through document analysis, field observation and 31 semiâstructured interviews. The study follows three research stages: data collection, process analysis/redesign, and validation through panels and focus groups.
Key Findings â Critical Issues
Five main categories of critical issues emerged:
- Lack of standardisation â differing workflows, tools, vocabularies, and documentation across agencies.
- Missing overall lifecycle vision â fragmented information stored in personal spreadsheets and nonâintegrated systems.
- Poor coordination â informal communication, siloed technical and administrative sectors.
- Obsolete technology â reliance on paper documents and CDâROMs, minimal automation.
- Inadequate maintenance procedures â âemergency logicâ dominates, no preventive maintenance plan.
Proposed ProcessâBased Solutions
The redesign focuses on the maintenance process, identified as the longest and most resourceâintensive phase. Two technological innovations are recommended:
- Building Information Modelling (BIM) â a shared 3âD database linking all asset data (design, construction, operation) to create a centralised knowledge repository.
- CaseâBased Reasoning (CBR) â a library of past maintenance cases linked to BIM, enabling retrieval of similar problems and solutions for faster decisionâmaking. The toâbe model introduces preventive maintenance (predictive, conditionâbased, cyclic) and integrates CBR before corrective actions. Both innovations aim to standardise workflows, improve data sharing, and support digital transformation.
Impact on Sustainability and Housing Policy
The study highlights that process standardisation and digital tools can enhance the efficiency of public socialâhousing management, reduce maintenance costs, and improve service quality for vulnerable households. By aligning with Industry 5.0 principlesâhumanâcentred, sustainable, resilient technologyâthese interventions support broader European goals for affordable, energyâefficient housing.
Validation and Stakeholder Reception
Validation involved panels of agency staff and two focus groups, including the Apulia Region Housing Policies Director. Participants recognised the value of a highâlevel process reference model and expressed strong support for BIM adoption and the shift toward preventive maintenance. Resistance to change decreased after the collaborative design phase.
Future Directions
The authors plan to extend the processâview approach to other agency functions beyond maintenance, replicate the study in additional Italian regions, and eventually develop a panâEuropean Social Housing Process Reference Model. Further research will explore full implementation of CBR and assess longâterm sustainability outcomes.
