The operational profile has a set of inputs to configure the thermal environment expected for the component. TI has made an assumption about the expected ambient temperatures of a typical use case - for example the IEC62380 Motor Control Profile. The user may alter these assumptions to meet their specific use case. The ambient temperature combined with the power consumption increases the junction temperature, which in turn, increases the raw (base) FIT rate.
