FMEA according to Wikipedia
FMEA stands for “Failure Modes and Effects Analysis”. It begins with a thorough functional analysis. FMEA is the core process of RCM. However, the FMEA article in Wikipedia is misleading. It uses outdated terminology that renders the subject of FMEA vague, confusing, and even mystical. FMEA depends on clarity. Maintenance depends on clear and simple terms…

Local, Next higher level, End effects
The FMECA process specified by MIL-STD-1629A provides a structured description of the Effects while the SAE JA1011 “minimum RCM” Effects are described by free text. One may question why LRCM chooses free text over the more stringent military structure The Effects long text field is one of several aspects that set RCM apart from the…

Effects – alternate usages
In many RCM software applications the Effects has a different usage from that which we describe in many places throughout this website. For example, in one RCM software application, when you open up the properties of a given Failure Mode from the RCM Hierarchy tree view, an elaborate set of tabs is provided. One of…

How does LRCM “improve” RCM?
Difficult discussions take place whenever people engage in the reconciliation of theory with practice. In many maintenance situations, the reality of a given maintenance event will be at odds with the current structure of the RCM hierarchy. The failure mode will be identified at one level of causality in the RCM knowledge base and at…

Effects
In most CMMSs where an RCM functionality has been introduced, the Effects tend to be short single phrases rather than narratives as suggested in the Moubray and SAE JA1011 standard. Effects according to the Moubray/JA1011 viewpoint include what happens at all levels in the organization and even beyond. Here is the JA1011 suggested content for…
