Checklist Maintainability

 

Maintainability describes how quickly and easily maintenance work can be carried out on a system. The following central question provides an insight into this complex topic: 

  • Can a specific maintenance task be carried out within a specified period of time for a specific component under given operating conditions with the aid of specified procedures and tools and under specified conditions?
     

Studies show that up to 60% of the causes of failure in technical systems can be traced back to errors in the development and design phase of the system. This reduces the availability and reliability of the systems and makes maintenance more difficult for the following reasons, among others:

  • Complex analyses for fault detection
  • Poor accessibility of sub-areas
  • Need for frequent maintenance work
  • High degree of difficulty of the work required
  • High costs and excessively long delivery times for spare parts
  • Inadequate and error-prone provision of equipment, processes and personnel
     

Good maintainability can be ensured through constructive & organisational measures, autonomous maintenance measures and measures for simple fault detection and repair. The LSM tool ‘Maintainability checklist’ provides support in checking a system for the most maintenance-friendly design possible.
