  1. Alignment and Maturity are Siblings in Architecture Assessment Bas van der Raadt (Capgemini) Johan F. Hoorn (VU) Hans van Vliet (VU) CAiSE 2005 - Wed. June 15 - Session 2A - 14:00 to 14:30

  2. Introduction • Enterprise Architecture (EA) to structure and improve complex situations • Practical problems with EA, e.g.: • Getting organizational acceptance • Finding proper resources (human and other) • Etc. • Desire to identify these problems through an architecture assessment • Create roadmap for improvement

  3. Agenda • Introduction to Alignment and Maturity • Existing architecture assessment models • Multi-dimensional architecture assessment (MAAM) • Visualization of MAAM tool • Example of assessment questionnaire • Assessment process • Summary & conclusions

  4. Alignment and Maturity • Architecture alignment is the fit between: • business and IT strategy • organizational and IT processes and structures • Architecture maturity is the ability to organization-wide manage the development, implementation and maintenance of architectures on various levels: • Business • Information • Information Systems • Infrastructure

  5. Existing models • Luftman’s alignment assessment: • Based on 6 variables: communications, competency/value, governance, partnership, skills, and scope & architecture • 5 alignment levels • Per variable 6 or 7 questions to determine level • Gartner and METAGroup maturity models: • Same structure as Luftman’s model • Comparable variables: process, governance, communication, technology, business IT linkage (alignment) • 5 maturity levels • Comparable questions to determine maturity levels

  6. Existing models • See either Alignment as explaining variable for Maturity, or vice versa • Allow one-dimensional assessments • Does not give sufficient insight • E.g. Human health assessment via Body Mass Index requires two dimensions (Height and weight) • Assign an organization an alignment or maturity level • Reaching the next level could become a goal

  7. MAAM • Two-dimensional (Alignment & Maturity) • Alignment en Maturity equally important variables • 6 explaining sub-variables: • Architecture development process • Architecture governance • Organizational support • Communication via and about architecture • Architecture scope • Human and other resources

  8. MAAM

  9. MAAM tool (visualization) Business management Architecture alignment IT department Architecture maturity

  10. MAAM tool (questionnaire)

  11. Assessment process • Gather data within different domains using the questionnaire • Cluster individual questionnaires and identify groups and their differences • Discuss these differences and their causes with involved management and architects • Identify solutions for getting ‘on the right track’

  12. Summary and conclusions • MAAM • Multi-dimensional (Alignment & Maturity) • Allows a more complete architecture assessment that identifies the ‘direction’ in which an organization moves • Based on existing models and improved by new theories from preliminary work (ICSE2004)
