Diese Lernkarten bieten einen Überblick über Service-Modularisierung und IT-Service-Management auf Universitätsniveau. Sie behandeln Themen wie SCORE-Methodik, Service-Design, -Sales, -Delivery und -Improvement, sowie die Integration von IT-Services und die Industrialisierung von IT-Services. Die Karteikarten sind besonders nützlich für Studierende und Fachleute, die sich mit der Optimierung von Service-Prozessen und der Implementierung von IT-Service-Management-Frameworks wie COBIT und ITIL befassen.

What is ITSM?

  • set of processes that cooperate to ensure the quality of IT Services according to the levels of service agreed to the customer

What is the motivation for ITSM?

  • compliance
  • internal pressure from own org.
  • competition
  • need for professionalization of IT

How are ITSM frameworks adopted in organizations?

  • Rules and directives (checklists)
  • Sequencing (Interconnected frameworks design)
  • Routines (Clarification of roles RACI)
  • Group problem solving and decision making (Support group)

Challenges in ITSM implementation (ITIL)

  • Lack of executive sponsorship
  • Business understanding of ITIL objectives
  • Lack of internal knowledge/skills of ITIL
  • Lack of funding/cost of adoption
  • Organization/cultural resistance to change
  • Maintaining momentum//pogress stagnates

What is ISO 20000 based on and what are the different sections?

ISO 20000 is based on BS 15000 and ITIL

  • ISO 20000 - 1: Service Management System Requirements
  • 2- Code of Practise
  • 5- Additions to Code of Practice (workbook for measuring maturity)

What Processes does ISO 20000 have?

same as in ITIL but less and defined under

  • Service delivery P (Design)
  • Control P (Transition)
  • Resolution P (Operation)
  • Relationship P 

---> Documentation in Service Management System (SMS)

  • Design and transition of new or changed services (Continual Service impr.)

How is the certification Process for ISO 20000?

  • Initiation
  • Preparation
  • Implementation (Management + Service Mgmt. Processes)
  • Audit
  • Operation

--> with Documentation and Project Management

what are the phases of COBIT?

  • Plan & Organise
  • Acquire & Implement
  • Deliver & Support
  • Measure & Evaluate

What are the promises of COBIT?

  • maintain high quality info to support decisions
  • business value from IT-enabled investments
  • oper. excellent through efficient + reliable application of technology
  • maintain risk at acceptable level
  • external legal regulatory and contractual compliance

What are the 5 princials of COBIT?

  1. Meet stakeholder needs
  2. Cover the enterprise end-to-end
  3. Apply a single integrated framework
  4. Enable a holistic approach
  5. seperate governance from Management

What is the difference from COBIT to ITIL?

ITIL vs. COBIT

processes vs control approach

operations vs leadership

business orientated vs business focused

lifecycle of services vs process oriented

value creation oriented vs control based

judged from customer vs measurements for adjustments

What are strenghts and weaknesses of COBIT and ITIL?

COBIT

+ structure

+ integrated maturity model

+ separation of business- IT targets

- not detailed enough

- RACI doesn't exist in every orga

cost vs benefits for gathering metrics often questionable

 

ITIL

+ Lifecyle thinking

+ customer orientation

- System for implementation is missing

- Inconsistencies

What is the motivation for Service Modularity?

  • services are key driver of growth and profitability
  • organizations develop service offerings combining services to tangible products
  • makes complexity manageable
  • enales parallel work and improvement
  • creates adaptivity to deal with uncertainty
  • can lead to decreased production costs
  • can decrease complexity by cross use of modules between services
  • may lead to better customer value and profitability by standardization

What are the characteristics of Service Modularity?

  • Service delivery by multiple service providers that specialize on the production of loosely coupled subtasks within the integrating framework of a modular servce architecture
  • --> reduces costs at constant flexibility in solutions

What are the risks of Service Modularity?

  • Loss of value for customers in case of holistic requirements
  • Pressure to bypass standards set by modular service architecture
  • Imitation and cherry picking
  • Core rigidity (Kernstück Starrheit)

--> Mitigation (Minderung) through front-back design 

  • Front end: customer specific service co-creation
  • Back end: production of standardized services

 

How does the circle of Modularisation of Customized Services work?

1. Development of Service Catalogue

2. Design, Sales, implementation of custom service solution

3. Service, solution transition, operation and support

4. Service solution improvement

What does Industrialization of IT Services mean?

  • Division of labour in the delivery of IT services established via IT outsourcing
  • Indications for reduced specifity of IT services (selective sourcing), increased prevelance of multi-sourcing and reduced contract durations
  • New paradigm: Service orientation drives business process focus, flexibility and re-use
  • Service orientation can be conceptualized as industrialization

How is the idea of reorganizing IT Service Production to follow the idea of service modularization?

Integration in It services!

 

Front end:

  • customer-centric
  • relationship management
  • project management

Back end:

  • product-centric
  • Econmies of scale and learning
  • Complexity management

 

What is the SCORE model?

SCORE is based on a Service Model with Four Elements

  • System Components
    • IT Components of a Service
  • Operations (Processes)
    • Processes that deliver Service
  • Results
    • Guaranteed Outpu (SLA)
  • Engagement
    • Episodes of collaboration between customer and provider for delivering customer-specific service (e.g. workshops, PM, incident reporting, service requests)

What is the SCORE Method?

Scoping--> Catalogue structure

Service analysis --> Service inventory

Module information --> Service modules

Solution configuration --> Customer solution

Extension --> New modules

What are the benefits of SCORE for Design, Sales, Delivery and Improvement?

  • Service Design (Reuse)
    • Shorter development time
    • Reduced development cost
  • Service Sales (Adaption)
    • Shorter Sales time
    • Reduced sales cost
    • Flexibility
    • Reduced delivery cost
  • Service Delivery (External delivery outsourcing)
    • Reduced service delivery costs
    • Shorter service delivery time
    • improved resource utilization flexibility
    • improved service quality
  • Service Improvement (Resource sharing)
    • improved flexibility
    • improved quality
    • Reduced service delivery
    • Reduced service delivery cost
    • Improve flexibility

 

What dependencies can exist in Service Analysis?

Technical (System component x System Component)

System (component x process)

Customer integration (Process x engagement)

SLA or warranties ( All x Results)

What do you do with delivery elements in SCORE and module types exist?

Combine delivery elements to service modules !

Module types

  • System Service Module (System or information as a service)
  • Process Service Module (Transformational and business capabilities as a service)
  • Integration module (Customer -specific engagement as a service

Who uses the SCORE Method?

Service architecture (Architect)

Service product (Product management)

Service configuration (Sales/ Pre-Sales)

What to use Score for?

  • Development of service solution catalogue
  • Design, sales and implementation of custom service solution
  • Service solution transition, operation and support
  • Service solution improvement

What facilitates modularization?

Technology

  • Service Support
    • Architecture and role concepts for delinating service responsibilities
    • Direct support of service functions in hardware and software
    • Access to product specific knowledge
  • Transformations options
    • Substituting dominant designs for customer specific components
    • use of open source components
    • Inhibitors: proprietary systems and interfaces and licence models

Organization

  • IT process definition
    • Definition of shared processes of service management
    • Differentiation of of processes for customer groups
    • Inhibitors: implicit service processes and no definition of customer groups
  • Shared service control modules
    • Shared methods for measuring and managing service performance
    • Inhibitors: Lacking or diverging modes of control among stakeholders
