3. The NESMA
playing field
 NESMA has her
initial base on
the cost-drivers
 Her contribution
radiates to the
four other areas

7. A Basis of Measurement
 Documents the measurement program for an organizational
unit, covering the process, organization and technology
required for the program

8. A well prepared Basis of Measurement will
 Document the purpose of the measurement program
 Document the overall measurement scope
 Provide a record of all documents used to prepare the measurement

program
Alert the stakeholders to potential measurement risks and
opportunities
Provide a record of agreements made during measurement
preparation
Act as a source of support during dispute resolutions
Support the establishment of relationships with other measurements
programs
Support the identification of relations / correlations between
measurements
Facilitate the review and validation of the measurements

9. Why Create a Recommended Practice?
 Setting up a Measurement Program is difficult
 Existing guidance is often too large and/or too detailed
 Many organizations seek a more workable set of
recommended practices
 This Recommended Practice is a starting document to be
enriched with Best Practices

10. Relation to Other Documents
 ISO 15939 (Sys and Sw Engineering – Measurement Process)
 Closely aligned
 The recommended practice is more compact and workable
 CMMI
 A practical implementation for Measurement & Analysis
 AACE CE-74 - Recommended Practice for a
Basis of Estimate – Software Services
 Sibling document
