From PM to services and service management
 Many of the IT projects that may be assigned to work on these days are likely to involve designing and implementing service systems
 Service projects have features that are different from traditional software engineering and similar projects

Skills and IT Services
› Shortage of people with integrated IT and Business training in Australia and overseas
– Not enough suitable applicants for jobs we need to fill in Australia
– expected to continue for next 3-5 years
– same situation at banks, airlines,
industry, government
› ….coupled with a skills problem:
– Graduates need different sets of skills in the business world today

Skills needed in business today…
Social Science (People skills)
Depth (deep problem solving expertise) Breadth (multidisciplinary approach, global outlook) Practical Experience (Internships, completed projects) Teaming (including ‘soft’ interpersonal skills ) Project Management (deadlines, budgets, leadership) Problem solving via social networks and computation Flexible, adaptive, and entrepreneurial
There is a skills gap in today’s graduates …technology OR business skills, but
may not have a good understanding of both
Services Sciences focuses on the multi- discipline skills that businesses are seeking today

Service System
– The basic unit of analysis is the service system,
– Service system is a socio-techno-economic system involving interplay among
people, technology, organizations to design, engineer, and deliver services
– Typically, customer and service provider agents work together using technology to co-produce value against some kind of service level agreement (SLA)
– Shared information helps coordinate activities – language, norms laws, measures, models, etc. (Spohrer et al. 2007)
– Simultaneity of production and consumption
– Growth requires innovation based on integration across technology, enterprise,
knowledge, and client needs.
– Significant focus on human agents and networks!

Service Systems
Knowledge-intensive service systems characterized by combination of:
› Person-to-person interactions among service provider and customer agents (service interaction networks),
› Computational processes and services,
› Technology-supported self-service,
› Multi-channel, multi-device, potentially location aware, and context based services
› Purposive – definable objectives and functions
› Systems partly designed; partly evolving – hence emergence,
› Large number of mutually interacting parts
› Potential for complementarity

Characterising IT services and the service sector
› Study of services is inherently inter-disciplinary
› Extreme diversity in the service sector – wide variation in their materiality and knowledge-intensity
› Nebulous nature of the output, difficulty in measuring the ‘product’; perishability
› Interactive nature of service design and delivery.
(CHIP – co-production, heterogeneity, intangibility, perishability)

Dynamics of Service Systems (contd.)
Service System Lifecycle model
Infancy Phase: high level of interactions and creative problem solving – flexible technologies – fast adaptation – explorative learning,
Maturing/Commoditization Phase: Coding knowledge into standard methodologies, processes, systems and, tools – automation, exploitation of existing knowledge – factory model.
Reincarnation Phase: Transformation thru new innovations and breakthroughs (e.g.. Cloud computing for infrastructure services)

Managing service systems
The University of Sydney Page 25

IT Service Management
› ITSM refers to a broad approach for conceptualising, designing, delivering, managing, and continuously improving service systems in organisations.
› ITSM frameworks (e.g. ITIL) has been developed to ensure that the right data, processes, people (skills), and technology are deployed so that the service system can be effective thereby enabling the organisation to achieve its goals.
26

Service Level Agreement (SLA)
› SLA is formal and documented agreement between a service provider and customer that provides full details of each service provided and the expected level of service provided (mostly stated using suitable metrics and key performance indicators (KPIs))
