    I understand that the IATF 16949 Clause no. 8.5.6.1.1 "Temporary Change of Process Controls" is applicable for the temporary change of Test or Inspection method, sample size, frequency defined in control plan. It is NOT applicable for the change of manufacturing process.
    The first paragraph confuse me and make me understand that the Mfg process change is included.
    (e.g. change from Automatic machine to Manual machine)

    The following paragraph is more clear as it mention about Test/Inspection only.

    Please let me know if I understand the scope of this requirement correctly.

    Yes, you understood currectly. even it is not a requirement to have an alternative process control for every primary control.
    When introducing new products, an organization should consider the risk of the primary control potentially failing and, based on risk and severity of failure mode, decide where alternative process controls are needed. When back-up or alternate process controls are needed, then both the primary and alternative process controls should be defined in the process flow, PFMEA, control plan, and the standardized work available.
    For existing processes, where there is a failure in the primary process control, and no alternative process control is defined, the organization should consider risk, (e.g. FMEA) and if approved, develop standardized work for an alternative process control, implement the controls, verify effectiveness through daily management, and then revalidate when the primary control is restored.
    Periodically, the organization shall review instances of where alternative process controls have been used and consider this as an input to update the process flow, FMEA, and control plan.
