  1. Practical aspects of data collection in industry Why is measurement so difficult to institutionalise? FiSMA cases and lessons learned Software Technology Transfer Pekka Forselius www.sttf.fi

  2. ”Measurement”? Software and system measurement is closely related to, and essential part of ”Measurement programs”, ”Data collection” and ”Benchmarking”. There may be measurement without any other connections or any public indications like those three above, but such is very difficult to survey.

  3. Is measurement important? • Both SPICE and CMMI standards demand evidence from measurement at higher maturity and capability levels. • Common sense tells us that we need measurement and data collection if we want to set realistic business goals and quantify improvement. Software Technology Transfer Pekka Forselius www.sttf.fi

  4. Finland and software measurement Where does the ISBSG data come? (2005) • Finland is (in many ways) one of the top countries in the Measurement World. • Activity in software project data collection is also an indicator of maturity level. per capita Finland and Australia are the most efficient so far Software Technology Transfer Pekka Forselius www.sttf.fi

  5. ISBSG data collection histogram • Getting better year by year • 2350 projects by the end of 2003 • 4000+ projects by today (2006) • Data collection looks popular and important! Software Technology Transfer Pekka Forselius www.sttf.fi

  6. Experience® data collection histogram • 750+ projects • The best organisations at CMMI/SPICE level 4, several on level 3. • SPI and project estimation training and consulting services are well established, benchmarking services available.

  7. ”Success” of measurement programs Of 610 measurement programs in place in 1998, only 140 survived the two-year mark as reported in data collected by Howard Rubin. Moreover, Dr. Rubin's data points since 1988 show a consistent 78% or higher failure rate for measurement programs.

  8. Introduction to FiSMA measurement methods and data collection tools • Experience® Pro 3.1 • Functional Size Measurement and Project Delivery Rate (FSM & PDR, FP & h/FP) • 21 productivity factors for development and 22 productivity factors for maintenance (ND21 & MT22) • Context variables (5-30) and other metrics details • Data quality criteria 2005 (max 100 points) Software Technology Transfer Pekka Forselius www.sttf.fi

  9. FiSMA measurement principle Same metrics, same methods and same tools throughout the development life-cycle and maintenance. Software Technology Transfer Pekka Forselius www.sttf.fi

  10. Sample of FiSMA cases – data collection 1990-2005 Software Technology Transfer Pekka Forselius www.sttf.fi

  11. Company-99 story (template) • Market position and competition • Ownership and visible goals • Measurement training, metrics specialist recruitment and R&D activity • Method and tool adoption approach • Recognition of success, rewarding and career opportunities Software Technology Transfer Pekka Forselius www.sttf.fi

  12. Why do so many measurement programs fail? Critical success factors of SPI: Source: P.Willman Software Technology Transfer Pekka Forselius www.sttf.fi

  14. ”SPI trinity” Improving measurement and estimation processes Functional size measurement Effort measurement rules Classification rules Situation analysis method etc... Experience Pro MS Office tools KnowledgePlan ISBSG tools etc... Measurement process owner? Top management connection? Memberships in SMA-network? Support and training? etc... Software Technology Transfer Pekka Forselius www.sttf.fi

  15. People skills • Situational leadership • Nonverbal language • NLP • Cultural aspects • Management by walking around • One minute management • Statuses • etc ... Software Technology Transfer Pekka Forselius www.sttf.fi

  16. Software Process Improvement Map Software Technology Transfer Pekka Forselius www.sttf.fi

  17. Conclusions Finland is known as a technologically advanced and exceptionally competitive country, where the software and systems development is well managed. ... but many Finnish companies have still lot to learn: -Realistic goals: what do they want to reach? -Correct timing: when to start measurement program? -Best practices and methods: what should they measure? Let’s keep learning from each other! Thank you! Software Technology Transfer Pekka Forselius www.sttf.fi
