Understanding Mda

  1. 1. Understanding MDA Alberto Lagna Alberto.Lagna@whiteBOX.it 10 october 2008 Understanding MDA n. 1
  2. 2. >apropos alberto.lagna • Computer Science graduate, Telco master • Independent consultant, working as software architect / team leader • Consulting on design and development of enterprise systems mainly based on JavaEE. • 15 years of working experience (2 big MDA projects): – IT asset repository in a big bank – MDA tool for software vendor • JUGTorino member • Promoting the use of free software and supporting the open source movement 10 october 2008 Understanding MDA n. 2
  3. 3. The Problem • Business is more demanding – Market ‘mutates’ constantly – New kinds of products needed – fast! – Many new products require new (and innovative) IT solutions • But: – IT platforms also mutate constantly – Legacy systems are tied to legacy platforms – IT has no universal integrating paradigm – So, IT culture is constantly tied up in maintenance and therefore slow to respond to change • Result: – Business-IT relationship under strain – Individual projects have high costs and high risk of failure – Projects not well-coordinated; no reuse 10 october 2008 Understanding MDA n. 3
  4. 4. Contributing Factors • Business does not describe its needs and opportunities in a consistent way • Business and IT speak very different ‘solutioning’ languages • IT does not follow consistent processes for creating, acquiring, integrating and customizing software • IT solutions are standalone; little reuse • Existing layers of legacy software, hardware and ‘muddleware’ compound all of the above. 10 october 2008 Understanding MDA n. 4
  5. 5. Is There a Better Way? • Much more rapid time-to- market • Significantly improved solutions quality • Significantly lower solutions lifecycle costs • End-to-end traceability – requirements to deployment • Improved overall business-IT alignment 10 october 2008 Understanding MDA n. 5
  6. 6. A Different Way of ‘Solutioning’….. Business Requirements Enterprise Reuse Repository New Business Reusable Business Models Model Patterns Reusable New Service Service Model Models Patterns New Implementation Reusable Models Design Model Patterns Deployed Reusable Software Deployed Components Components 10 october 2008 Understanding MDA n. 6
  7. 7. ….and, a Different Development Process Business Models Business Analyst Solution Models Solutions Designer Implementation Models Software Designer Deployable Software Software Implementer 10 october 2008 Understanding MDA n. 7
  8. 8. What about MDA? Computationally •Separation of concerns Independent •Multiple viewpoints Model (CIM) Business Analyst •Multi-level reuse •Precise information flows Platform •Full traceability Independent Model (PIM) Solutions Designer Platform Specific Model (PSM) Software Designer Deployable Software Software Implementer 10 october 2008 Understanding MDA n. 8
  9. 9. Why MDA? • Based on proven best practices and open standards • Supported by 900+ OMG members • Widely implemented in commercial and open source tools • Applicable to a wide range of business and computing problems • Highly adaptable to different organizations, project types, toolsets, technologies, etc. • Supports all forms of development and deployment, including outsourcing and off- shoring 10 october 2008 Understanding MDA n. 9
  10. 10. Who is Using MDA? • Government • Financial Services • Aerospace, Defense • E-commerce • Telecomm • Manufacturing • Biomed • ……. (see www.omg.org/mda) 10 october 2008 Understanding MDA n. 10

  13. 13. MDA tools and frameworks • which one do I have to choose? • which has the best fit to my requirements? • what are my requirements? 10 october 2008 Understanding MDA n. 13
  14. 14. Realistic Concerns • Can it really work at our company? • How much time/money could it save? • Is it really worth the time, cost, effort and risk to implement? • What will the ‘to-be’ state of our organization really look like? • How do we manage/govern our organization’s transition to MDA • How do we get started? 10 october 2008 Understanding MDA n. 14

  20. 20. MDA tool requirements • for YOUR target platform – supports custom metamodels • addresses full lifecycle – metamodels, tranformation, generation • Advanced capabilities – reverse eng, versioning, validation, simulation • integration with tools • standard conformance 10 october 2008 Understanding MDA n. 20
