No Fault Found Problems in Asset Management
Within aerospace and defence sectors, maintaining asset availability during operational service has become more important than quality of service throughout the system life cycle. This requires organisations to establish cost effective strategies to manage uncertainties within their value led services e.g. maintenance activities. In large organizations, it is not always apparent whose decision affects the outcome the most. Often, accountability moves away from the designated organization personnel in unforeseen ways, and depending on the decisions of individual decision makers, the structure of the organization, or unregulated operating procedures may change. This can have far more effect on the overall reliability leading to inadequate troubleshooting, repeated down-time and reduced availability. This chapter focuses on discussing the No Fault Found problems in aviation and highlights the drivers that influence its decision making process. It further articulates the contents of tacit knowledge and discusses the knowledge gaps with current management policies.
