  • 1. Services Science and Enterprise : A Happy Marriage Prof. Dimitri Konstantas Vice-Dean Institute of Services Science Faculty of Social Sciences and Economics
  • 2. Services Today
    • Very simple for the users
    • BUT
    • Very complex for the managers
  • 3. Some Facts
    • Services represent between 70% and 80% of the European and Swiss economy !!
    • We do not quite understand how to measure the productivity of those that produce services
    • The boundaries between production and distribution are fuzzy
    • The value of the services is fuzzy
    • The « products » are changing constantly
    • The user contributes in the production and even the design of a service
  • 4. What is the problem with today's enterprises?
    • New models are appearing
      • Software as a Service, storage as a service, cloud computing
    • Global interactions in a global economy
      • Your competitor is at the other side of the planet
    • Niche markets become the driving force for an enterprise
      • The Long tail market
    • Customer driven business
      • If you don't do it, your competitor will
  • 5. Ever increasing technological complexity
    • Enterprises need to offer service BUT services are difficult to both specify and maintain:
    • Scale – Highly complex and ambitious artefacts (and things are getting worst every day!!)
    • Integration – need to take into account and master "academic disciplines" ranging from social sciences to mathematics, engineering and economics (but who understands all that?)
    • Environment - many of the systems operate in a world of uncertain and shifting policy, economics and legislation
    • Communications - these large scale systems and not understood in their totality, leading to a poor understanding on key decisions (process, expectations, financial policy…)
  • 6. The Human factor
    • Senior management:
      • Don't understand technologies
      • Can be conservative
      • More comfortable with conventional business relations with vendors
      • May be over-cautious about being sued
    • Users:
      • Can be conservative and many don't understand technologies
      • Those that do may use the technologies in dangerous ways
      • Others may have high expectations (computer games!)
  • 7. So, what do we need? New Principles!!
    • A change in culture
    • Be more open
    • Revisit Acceptable Use Policies – should not be a control mechanism
    • Develop more sophisticated models for standards, accessibility, open source, …
    • Integrating IT Policies With Institutional Policies
    • Holistic or blended approach - flexibility in implementation
  • 8. Services Science can be the solution The enterprise today The Service Science based enterprise
  • 9. Service Science based enterprise system characteristics
    • Loosely coupled : minimizes dependencies between services.
    • Contractual : adhere to agreement on service descriptions.
    • Autonomous : control the business logic they encapsulate.
    • Abstract : hide the business logic from the service consumers
    • Reusable : divide business logic into reusable services.
    • Composable : facilitate the assembly of composite services.
    • Stateless : minimize retained information specific to an activity.
    • Discoverable : self-described so that they can be found and assessed.
  • 10. Services Science advantages for the enterprise
    • Vendor diversity
    • Intrinsic interoperability
    • Inherent reusability
    • Extensibility
    • Organizational agility
    • Incremental implementation
    • And from the technical point of view
    • Applications can be exposed easily to diverse clients
    • Existing services can be easily reused
    • New applications can be created or modified
      • the marginal cost of creating the n-th application is zero, as all of the software required already exists to satisfy the requirements of other applications
  • 11. Why SS Makes Sense: More Business Benefits
    • Business people understand services
      • So IT people can talk with them more easily
    • Application integration becomes cheaper and faster
      • Which makes implementing business processes easier
    • Business processes can more easily be changed or replaced
      • Because they’re built from autonomous services with well-defined interfaces
  • 12. Some Risks
    • Does it make sense to build most new apps in a service-oriented style?
      • Yes: there are exceptions, however
    • Which are the "component services"?
      • Exposing the right services is harder
    • Can service-oriented apps perform?
      • Yes: perhaps 10-15% of people have performance problems today (typically caused by bad design or very high load on a service)
    • Can the organizational challenges be overcome?
      • The real challenges are human, not technical
  • 13. The way towards a Service Science enterprise
    • Maturity Models
    • Open Group –OSIMM
    • Gartner Group SOA Maturity Model
    • SONIC vendor group SOA Maturity Model
  • 14. An Early Example: Credit Suisse
  • 15. Credit Suisse: Services Growth 1999 2000 2001 2003 Exposed business services 35 173 500 800 Front-end applications 5 21 50+ 150+ Users 800 9.000 100.000 100.000+
  • 16. Credit Suisse: What They Learned
    • Challenges:
      • An expensive project
        • Return on Investment (ROI) took time to materialize
      • Performance wasn’t good initially
      • Security and management were custom
      • Business units resisted sharing their services; they were “encouraged”
    • Benefits:
      • Faster application development
        • 75-80% of required services already available
      • Savings of several million dollars a year
