Software • Performs a function(s), and • Embodies a culture and viewpoint
The functions of maintenance (decision optimization) software • To build a decision model (a measuring stick) for interpreting condition monitoring data, optimally. • To deploy that model using an automated “intelligent” agent. • To verify the model’s performance and, to improve it continuously.
The viewpoint (culture) Premise 1 • Recorded information on what happened has value Premise 2 • We may convert that information to practical, structured reliability-centered knowledge1 Premise 3 • Manage that knowledge using a dynamic, continuous improvement process 1 Knowledge – the ability to make good, verifiable maintenance decisions.
PF1 FF2 S3 What do we need on the work order for reliability analysis? 1 Potential failure – has no or relatively minor consequences 2 Functional failure – has consequences resulting from loss of function 3 Suspension – a renewal of a failuer mode / component for reasons other than FF or PF

Benefits of living RCM • Unification of RA, RCMA, and Optimized CBM with the CMMS. • Residual life estimation and survival probability capability in CBM program • CBM decisions based on true asset condition. • Inherent measures of the effectiveness of those decisions. • Better communications through the use of RCM thinking in daily practice • Inherent continuous improvement
Achieving reliability requires us to perform three principal types of activities: • Monitor asset performance, • Tells us to what extent we are maintaining function. • Manage / grow / use reliability knowledge, • Tells what we need to do to maintain function • Analyze reliability. • Tells us about asset failure behavior • So that we can refine the knowledge base
