• Quality control charts
• Variable sample size (VSS)
• Variable sampling intervals (VSI)
• Variable sample size and sampling intervals (VSSVSI)
• Markov chain
• Adjusted average time to signal (AATS)

We provide some unifying definitions, make some corrections to articles by Faraz and Parsian (J Stat Pap 47:569-593, 2006) and Costa (J Qual Technol 26:155-163, 1994; 29:197-204, 1997), and using these provide more accurate tables of results and comparisons of control charts. We also investigate the impact of an incorrectly specified process shift on signal frequency.
