The development process applied to the Tokeneer ID Station high-
integrity development can be summarised in terms of the following key
phases:

    * Requirements analysis (the REVEAL=AE process)
    * Formal specification (using the formal language Z) <=3D=3D=3D not man=
y
folks can do this (or want to)
    * Design (formal refinement of the specification and the INFORMED
process)
    * Implementation in SPARK Ada
    * Verification (using the SPARK Examiner toolset)
    * Top-down system testing
