Business Focused CMMI at Ericsson, Ben Linders, SPIder 2001

  1. 1. Ben Linders, Ericsson EuroLab Netherlands 1SPIder, September 25, Utrecht Business Focused CMMI at Ericsson SPIder, September 25, Utrecht Ben Linders Ericsson EuroLab Netherlands, Rijen (N.B.) Ben.Linders@eln.ericsson.se, +31 161 24 9885
  2. 2. Ben Linders, Ericsson EuroLab Netherlands 2SPIder September 25, Utrecht Overview • History of applying SW CMM • CMMI vs SW CMM • Business Focused CMMI Organizational Performance Improvement!
  3. 3. Ben Linders, Ericsson EuroLab Netherlands 3SPIder September 25, Utrecht Ericsson EuroLab Netherlands • Worldwide Ericsson R&D company • Wide product range: – Base stations, UMTS – Charging, Internet Applications – Intelligent Networks and Services, Announcements – Bluetooth, Business Cordless • 950 employees, in the south (Rijen) and the east (Enschede, Emmen)
  4. 4. Ben Linders, Ericsson EuroLab Netherlands 4SPIder September 25, Utrecht Assessment History • CMM SW: Full assessments: – 1994: First assessment – 1995: CMM Level 3 – 1998: Assessed Level 4 • P-CMM: Company wide assessments: – 1998: First assessment – 2000: Re-assessment • SE-CMM: Studied • Light assessments for CMM SW, P-CMM, and CMMI – Ongoing from 1996 - 2001 (several done each year)
  5. 5. Ben Linders, Ericsson EuroLab Netherlands 5SPIder September 25, Utrecht New Assessment Requirements • Aligned to needs of the organisation Only assess where you can and want to improve • Focus on improvement, not on levels • More frequent assessments • Smaller scope, more specific findings • Lower cost ²Business Goal Focused Assessments
  6. 6. Ben Linders, Ericsson EuroLab Netherlands 6SPIder September 25, Utrecht CMMI vs CMM SW • Philosophy – Integration of models – Framework, toolbox – Rating and improvement – Common assessment method • Structure – Process Areas – Goals & practices – Staged & continuous – Maturity & Capability level • Scope – Project Management – Process management – Engineering – Support « Incl. Systems Engineering Replaces SW CMM, SE-CMM, IPPD CMM, and SA CMM (not P-CMM)
  7. 7. Ben Linders, Ericsson EuroLab Netherlands 7SPIder September 25, Utrecht Business Focus in CMMI • Continues representation: – Toolbox with Process Areas – Pick only useful PAs – Measure on Capability Level • PA Purpose: Link to business goals • But, business processes are lacking: – Goal setting, strategies, customer focus – Leadership, people development (P-CMM) – Partnerships, environment, etc
  8. 8. Ben Linders, Ericsson EuroLab Netherlands 8SPIder September 25, Utrecht Why did Ericsson choose CMMI? • Continuous model: Focus on improvement • Up to date collection of “Best Practices” • Official standard (replace CMM SW 2.0 draft C) • More suitable assessment method: Class C More info: http://www.sei.cmu.edu/cmmi/
  9. 9. Ben Linders, Ericsson EuroLab Netherlands 9SPIder September 25, Utrecht Business Focused Assessment Method SEI/Ericsson CMMI Class C Pilot Assessment: • Identify business goals where improvement is needed • Select Process Areas • Setup team, select interviewees • Questionnaire + Consensus Meeting • Findings, and identify actions
  10. 10. Ben Linders, Ericsson EuroLab Netherlands 10SPIder September 25, Utrecht CMMI Pilot in Figures • 5 assessments, 4 in Q4 2000, 1 in Q1 2001 – Process Management (7 PAs) – Project Management (6 PAs) – Requirement Management/Development (2 PAs) – Engineering (4 PAs) – Decision Analysis & Resolution (1 PA) • 4 Assessors, 390 Mhrs (19.5 Hr per PA) • 42 Interviewees, 159 Mhrs (3.8 Hr per person) • 54 Strengths, 85 Weaknesses • 70-80% of the finding led to actions
  11. 11. Ben Linders, Ericsson EuroLab Netherlands 11SPIder September 25, Utrecht Benefits: Improved Performance • Project Management: Major improvements – Lead time precision above target – Cost precision above target • Engineering: Early benefits – Focus on deployment of technical process – Efficiency needs further improvement • Process Management: Institutionalised – Effective application of audit, RCA, assessment, etc
  12. 12. Ben Linders, Ericsson EuroLab Netherlands 12SPIder September 25, Utrecht CMMI Pilot Evaluation (1) • SEI feedback form, 11 returned from 23 (48%) – No major problems missed – 1 person said that some minors were identified wrongly, 10 said no wrongly identified problems – 10 persons said that assessments where always done effectively, 1 most often, nobody said ineffective
  13. 13. Ben Linders, Ericsson EuroLab Netherlands 13SPIder September 25, Utrecht CMMI Pilot Evaluation (2) How accurate was the assessment 0 1 2 3 4 5 Much better Somewhat better About the same Somewhat worse Much worse Don't know How well did the assessment find strong points 0 2 4 6 8 Very well Reasonably well Not very well How well did the assessment find major problems? 0 2 4 6 8 Very well Generally well Not very well
  14. 14. Ben Linders, Ericsson EuroLab Netherlands 14SPIder September 25, Utrecht Conclusions, where do we go from here? • Business Goals focus is a winner! – Compact assessment, better cost/benefit – 3 more assessments done in Q1/Q2 2001 – Useful actions, which have improved performance – Further integration with goal setting and KPIs • Method is being spread within Ericsson – More class C (light) assessments – Assessors network for further development
