Figure 2.7. Flowchart of mistake-proofing tools

Flow chart is divided into three sections; Enabling tools, design tools, and Implementation tools. 'Enabling tools' section lists five functions; Process mapping, Just culture, Event and near-miss reporting, Root cause analysis, and Visual systems (5S). 'Design tools' section lists six functions, each leading to a 'Brainstorm' function, then to a filter which evaluates the number of possible solutions arising from the 'Brainstorm.' If the Brainstorm yields at least the desired number (n) of solutions, the flow continues on to the function labeled 'Solution Set.' If 'n' is less than the desired number of solutions, the flow continues to the next function. In sequence, the design tools functions are: Failure modes and effects analysis (F.M.E.A.); Fault tree analysis; Multiple fault tree analysis; T.R.I.Z.; Weaker cues; and Change focus or give up (last function, yielding zero solutions), which returns to 'Brainstorm'. In each case, 'Brainstorm' activity resulting in solutions greater than or equal to 'n' continue to the 'Solution set' function, which then continues to the final section, 'Implementation tools.' The 'Implementation tools' section is described: 'Lots of tools, but beyond the scope of this book.'

Notes: The variable n equals the number of solutions you would like to generate before selecting the best one.
TRIZ is the acronym for the "Theory of Inventive Problem Solving" transliterated from Russian.
