Range Statement
|
The range statement relates to the unit of competency as a whole. It allows for different work environments and situations that may affect performance. Bold italicised wording, if used in the performance criteria, is detailed below. Essential operating conditions that may be present with training and assessment (depending on the work situation, needs of the candidate, accessibility of the item, and local industry and regional contexts) may also be included. |
Sampling scheme | Sampling scheme may include:sampling for attributes or sampling for variablesbatch, continuous or custom made productsnumber of items/samplessize of sampletiming of samplinglocation of sampling pointstype of samplenumber/type of measurements to be done on each samplesampling equipmentmeasurement/testing equipment/methods |
Procedures | Procedures includes all work instructions, standard operating procedures, formulas/ recipes, batch sheets, temporary instructions and similar instructions provided for the smooth running of the plant. They may be written, verbal, computer based or in some other form.For the purposes of this Training Package, ' procedures' also includes good operating practice as may be defined by industry codes of practice (eg Good Manufacturing Practice (GMP), Responsible Care) and government regulations. |
Handle data | Handle data may include:calculating means, ranges, mean of means, standard deviation (using appropriate calculation aids)entering data into a software packagerecording data either in writing or electronicallyother required manipulations of the data. |
Control chart | Control charts may include:runtallymean/rangeattributesother relevant charts |
Random | Random variation is the term used in statistical control to refer to those variations for which no cause can be found. |
Non-random | Non-random, also called identifiable cause, or assignable cause or special cause are those variations for which a cause can be found and so the cause of the variation eliminated. Non-random variation may also be used to predict possible breaches of the control limits. |
Control limits | Control limits, also referred to as process capability are those limits within which the process will operate if it is 'under control'. |
Cost of non-conformance | Cost of non-conformance includes:reprocessing/reworkexpeditingunplanned serviceexcess inventorycomplaint handlinedowntimereturnsscraplabour costsmaterial costsinfrastructure costs/overheadutility costs |
Appropriate limits | Appropriate limits may include:1 sigma warning limits2 sigma warning limits3 sigma control limits6 sigma limits |
