#REDIRECT [[Reliability_Growth_Planning#Nominal_Failure_Intensity_Function]]
The nominal idealized growth curve failure intensity as a function of test time  <math>t</math>  is:
 
::<math>{{r}_{NI}}(t)={{\lambda }_{A}}+(1-d){{\lambda }_{B}}+d\lambda \beta {{t}^{\left( \beta -1 \right)}}\text{ for }t\ge {{t}_{0}}</math>
 
:and:
 
::<math>{{r}_{NI}}(t)={{\lambda }_{I}}\text{ for }t\le {{t}_{0}}</math>
 
where  <math>{{\lambda }_{I}}</math>  is the initial system failure intensity,  <math>t</math>  is test time and  <math>{{t}_{0}}</math>  is the initialization time, which is discussed in the next section.
<br>
It can be seen that Eqn. (Nominal FI) is the failure intensity equation of the Crow Extended model.
