Home is a safe, secure, and stable place where people live together. According to surveys, plumbing and electrical systems are among the most common home problems. (International Association of Certified Home Inspectors, 2022) These issues affect the safety of homes and homeowners, such as fires, electric shocks, fires, etc. Therefore, home repair and remodeling programs are essential to prevent, detect and control these problems.
Job analysis is one of the key processes in identifying tasks, roles, and responsibilities, and qualifications for home repairs and/or remodeling. There are two ways to mitigate these problems. The first is to prevent any problems before they occur in the future, such as monitoring and maintenance, and the other is to detect and control problems that have already occurred, such as repairs and inspections of the finished results.
The Plan-do-check-act Framework (PDCA) is a framework to analyze the functions, skills, and abilities required to implement a project, and also provide guidelines for planning, implementing, inspecting, monitoring, and maintaining to improve the home system. The initial process of job analysis is to gather useful and relevant information, and understand the basic knowledge of plumbing and electrical systems.
Homeowners must identify problems and causes of plumbing and electrical systems, and then consider whether to repair and/or rebuild it yourself or hire a professional. Do it yourself (DIY) and hire a plumber and/ or electrician to have different budgets, schedules and action plans. This research also provides steps of processes and checklists for the tasks, roles, and responsibilities that homeowners must take to keep their homes safe.
