Assessing the Maintenance Strategy Decision: In-House Versus Contract Maintenance of Equipment in Roofing Sheet Manufacturing Companies in Kumasi, Ghana

Abstract

Aims: This study aimed to assess the degree to which in-house and contract maintenance practices are implemented in roofing sheet manufacturing firms located within the Kumasi Metropolis of Ghana, and to identify the factors that influence these firms' decisions to adopt specific maintenance strategies.  Study Design: The study utilized a descriptive design.  Place and Duration of Study: The research was conducted in the Kumasi Metropolis of the Ashanti Region, Ghana, from February to October 2024.  Methodology: A survey was conducted involving all 13 roofing sheet manufacturing companies, which represent the complete set of such firms. Data were analyzed with Microsoft Excel [Version 19], and the results were displayed in tables and charts.  Results: The findings of the study indicated that contract maintenance is utilised by nearly all roofing sheet manufacturing companies in Kumasi. Additionally, it was found that in-house maintenance practices are employed for particular equipment. The study also revealed that contract maintenance is preferred in scenarios that require external expertise or specialised maintenance equipment. Furthermore, it was determined that all roofing sheet manufacturing companies in Kumasi utilise both in-house and contract maintenance for their machinery.  Practical Implications: Maintenance strategies have significant practical implications for companies, especially those involved in manufacturing, infrastructure, energy, logistics, or any sector where equipment reliability is critical. The choice and implementation of maintenance strategies can directly impact operational efficiency, cost control, safety, compliance, and competitiveness. Conclusion: Based on this study's findings, both in-house and contract maintenance are crucial for the upkeep of company equipment. Nevertheless, contract maintenance is predominantly favoured for tasks necessitating external expertise or specialised maintenance tools. This research's outcomes can serve as a useful resource for stakeholders and companies in developing maintenance policies for their equipment. This study is limited in scope to roofing sheet manufacturing companies within the Kumasi Metropolitan Area in Ghana. It is suggested that future research should be extended nationwide to obtain a comprehensive overview of the maintenance strategies of all roofing sheet manufacturing companies in Ghana.
