Shewhart (QCC = Quality Control Chart)
A record sheet for the graphic representation of statistical sampling parameters. The QCC helps to visualize the behaviour of a process over the time. The course of the measured points on the QCC allows to deduce the coincidental and/or systematic influences so that corrective actions can be taken before exceeding the tolerance limits.
SPICE (Software Process Improvement and Capability Determination)
International standard for conducting assessments of business processes in software development. SPICE provides – alike CMMI – a statement on how well a company uses and sticks to processes. The corresponding standard is ISO/IEC 15504-5:2006.
A-SPICE or Automotive SPICE is a specific variation which covers and evaluates development processes for automotive control units.
SSA (interface analysis)
An analytic method with the aim to identify systematically risks (regarding concept, production, assembly etc.) at interfaces inside of systems, to prioritize the processing of the interfaces and to define countermeasures against potential failures. An interface analysis is particularly recommended for complex or new systems or in conjunction with a change of the supplier and has to be performed in the development phase.
