| Abstract: | Complex systems maintenance management can be supported by using technologies such as computerised maintenance management systems (CMMSs). However, CMMSs face usability issues. To design a usable system, usability standards should be adopted, which are guidelines that aim to improve product acceptability and user satisfaction. This research focused on designing a usable CMMS prototype interface for a vessel’s (ship) complex system as a case study for Thales B.V. Throughout the research, the complex system focus shifted multiple times, due to COVID-19, from general complex systems to TACTICOS: a combat management system from Thales B.V. The structure of the paper is divided into three connected phases: 1) Definition of a framework on issues with complex systems maintenance and CMMSs. A systematic literature review and interviews with stakeholders from a Thales B.V. complex system was performed to identify issues with complex systems maintenance and CMMSs. This resulted in a list of 28 identified issues in total, which were reviewed by participants in a questionnaire. In total, 15 stakeholders participated, from which a list of 5 main issues was identified with complex systems maintenance and CMMSs. 2) Design of a CMMS prototype: A case study for Thales B.V. The list of 5 main issues from phase 1, together with a carried-out task analysis on operators and maintainers performing maintenance tasks in complex systems was used to inform the design of a CMMS prototype for a vessel’s complex system at Thales B.V. 3) Usability testing of the CMMS prototype. Small-scale remote usability testing was performed with 11 stakeholders from Thales B.V. The results indicated a total of 69 feedback remarks, an ‘above average’ score on the system usability scale (SUS) and a ‘below average’ net promoter score (NPS). The feedback remarks were considered in a redesign of the prototype. This research faced three main limitations, from which the most significant one explains that end-users of CMMSs were out of reach. Nonetheless, the phases of method applied can be reused by Thales B.V. in future work when designing a usable CMMS. |
