General Tools

Identify, prioritize, and integrate factors into a designed experiment.

 Name: Link(s)DescriptionApplication
Fishbone Diagram
Documents initial list and sorting of factors that could affect test outcomes.Planning
  • Factor Management
Input-Process-Output Diagram
Groups factors according to management strategy to assist in down-selection and design.Planning
  • Factor Management

 

Reliability Test Plan Tools

Determine test size required to confidently establish reliability.

 Name: Link(s)DescriptionApplication
Duration Based Operating Characteristic Curves
Generates OC curves for exponential data after calculating maximum allowed failures given inputs of test length, reliability requirement, and desired level of confidence.Planning
  • Reliability
Binomial Operating Characteristic Curves
Generates OC curves for binary reliability. Given consumer risk (beta), the maximum acceptable proportion of failures (requirement), and number of trials, this spreadsheet calculates the maximum number of failures which still results in acceptance of the system. Planning
  • Reliability
