σ = √(Σ(xi - μ)² / N)
where σ is the standard deviation, xi is each data point, μ is the mean, and N is the number of data points.
Process Capability (Cp and Cpk): These indices measure the ability of a process to produce within specified limits. The formulas are:
Cp = (USL - LSL) / 6σ
Cpk = min((USL - μ) / 3σ, (μ - LSL) / 3σ)
where USL and LSL are the upper and lower specification limits, μ is the process mean, and σ is the standard deviation.
Control Chart (X-bar and R-chart): These charts monitor the stability of a process over time. Key formulas for calculating control limits are:
UCL = X̄ + A2 * R
LCL = X̄ - A2 * R
where X̄ is the sample mean, A2 is a constant based on sample size, and R is the range of the sample.
FMEA (Failure Modes and Effects Analysis): A structured approach to identifying and prioritizing potential failure modes in a process. Risk Priority Number (RPN) is calculated by:
RPN = Severity x Occurrence x Detection
where Severity, Occurrence, and Detection are rated on a scale of 1 to 10.
Five Whys: A problem-solving technique used to identify the root cause of an issue by asking “Why?” five times. This helps uncover underlying issues that may not be immediately obvious.
