What is psm
What is PSM?

  • A Primary Measurement and Analysis Process Used by DoD, Government, and Commercial Programs

  • Technology Based on Actual Experience on Real Programs

  • A Fully Integrated Approach Including Guidance, Tools, Training, Implementation Workshops, Support Products, and a Qualified Technical Team


Key measurement concepts
Key Measurement Concepts

  • Measurement is a Process - Not a Pre-Defined List of Graphs or Reports

  • The Measurement Process is Flexible - Adapted To Meet Specific Project and Organizational Objectives and Information Needs

  • The Measurement Requirements are Integrated Into the Project Technical and Management Processes


Common information needs
Common Information Needs

  • Schedule and Progress

  • Resources and Cost

  • Product Size and Stability

  • Product Quality

  • Process Performance

  • Technology Effectiveness

  • Customer Satisfaction

Iso iec 15939
ISO/IEC 15939

  • PSM Was Base Document for This Standard

  • Specifies Required Activities and Tasks of a Measurement Process

  • FCD Ballot Passed in May 2001 With Only 1 Dissenting Vote - All Comments Resolved at ISO Plenary

  • Terminology Was Adjusted for Consistency With ISO/IEC 9126, 15498, and 14143 Series

  • DIS Ballot Will be Released in September 2001 - Ballot Will Close in November 2001 - International Standard in Late 2001

CMMI M&A

  • ISO/IEC 15939 Was Base Document for the Measurement and Analysis Process Area

  • CMMI M&A Describes How to Evaluate a Measurement Process

  • M&A Is a Level 2 Process Area

  • Pilot Assessments Are Being Conducted in 2001


ISO 9000-3Quality management and quality assurance standards - Part 3: Guidelines for the application of ISO 9001 to the development, supply, installation, and maintenance of computer software


Iso 9000 3
ISO 9000-3

  • 9000-3 Is Being Updated by SC7 as Part of the ISO 9000:2000 Update

  • Part 8, “Measurement, Analysis and Improvement”, Was Updated for Consistency With 15939

  • Standard Is at Working Draft Stage - Expected Publication Date Is 2002/2003
