A Basis of MeasurementDocuments the measurement program for an

organizational unit, covering the process, organization and technology required for the program

A well prepared Basis of Measurement willDocument the purpose of the measurement programDocument the overall measurement scopeProvide a record of all documents used to prepare the

measurement programAlert the stakeholders to potential measurement risks and

opportunitiesProvide a record of agreements made during measurement

preparationAct as a source of support during dispute resolutionsSupport the establishment of relationships with other

measurements programsSupport the identification of relations / correlations between

measurementsFacilitate the review and validation of the measurements

Why Create a Recommended Practice?Setting up a Measurement Program is difficultExisting guidance is often too large and/or too detailedMany organizations seek a more workable set of

recommended practicesThis Recommended Practice is a starting document to

be enriched with Best Practices

Relation to Other DocumentsISO 15939 (Sys and Sw Engineering – Measurement

Process)Closely alignedThe recommended practice is more compact and workable
