4. CONCLUSIONS

It goes without saying that a diagnostic system will be no good unless the problem, involving correct and timely diagnosis, has not been well conceptualized.

Additionally, conceptualization is only one stage of a global methodological process, in this case the IDEAL methodology (Gómez et al., 1997) and its associated life cycle.

Finally, it is important to note that this diagnostic methodology generally and the conceptualization phase particularly is backed by the construction of 20 general-purpose ES and 6 diagnostic ES in fields such as: medicine; aircraft; vehicle; and ship maintenance; and nuclear plants.
