Enterprise Service Management (ESM) and YaSM
What is enterprise service management?
There is no "official" definition of enterprise service management, but some research on the web suggests that most people would agree with the following definition (a variation of the definition for service management from the official ITIL® glossary [1, 2]):
- Enterprise service management (ESM)
- Enterprise service management (ESM) is an approach for providing value to customers in the form of services. ESM includes capabilities for designing, implementing, operating and improving services.
This contrasts with IT service management (ITSM) which is specifically about the management of IT services.
As a side note, Wikipedia also offers a definition that refers to enterprise service management as a "category of business management software ... and the use of service processes and technologies across an organization" [3]. This confuses two concepts which are really different:
- Enterprise service management as a management discipline, and
- ESM tools or software that are used by organizations to support their ESM processes
Therefore we do not agree with the definition in Wikipedia.
How enterprise service management evolved out of IT service management
The discipline of service management was pioneered in the field of information technology (IT) services. Back in the 1980's, the British government found that many of the IT services it procured did not meet expectations, and commissioned the development of methods for the provision of IT services with better quality at lower costs.
This led to the publication of a catalogue of best practices for the IT organization, which today is known as ITIL® (IT Infrastructure Library). Over the years, ITIL was updated several times, and it's probably fair to say that the ITIL advice is followed - to varying degrees - by the majority of organizations that provide IT services.
So ITIL was developed specifically for the domain of IT services, and therefore many parts of ITIL are about managing the technical infrastructure that underpins the business of IT service providers.
But it was always obvious that there are many similarities between providers of IT and non-IT services. Everyone in the business of providing services should, for instance, know the needs of their customers and have methods in place for offering and managing a range of services that fulfill those needs.
What happened is that, as ITIL grew popular, more and more people realized that ITIL and ITSM best practice can be put to good use in all organizations or business functions that provide services, for example in the fields of healthcare, banking, human resources, legal services, etc.
The spread of ITIL beyond the framework's traditional use in IT was certainly driven by the many "ITIL-compatible" tools that are readily available on the market: Service providers of all sorts discovered that their operations can benefit from tools such as help-desk software or self-service portals.
Still, we are at the beginning and the idea that ITIL principles can be applied outside IT organizations is only now gaining traction. In this context, "enterprise service management" has emerged as a new catchphrase. It is often used when people speak or write about "applying ITIL and ITSM best practice in areas beyond IT".
Benefits of applying service management best practice
Enterprise service management does not have a long history yet, but IT organizations have been following the IT service management guidance for decades and seen many improvements.
Since ESM has its roots in ITSM, both concepts will, by and large, offer the same benefits. In particular, we can expect the following advantages:
- Cost savings through more efficient processes and workflows
- Improved customer satisfaction through customer focus and seamless support
- Long-term success through active management of the service portfolio.
Enterprise service management processes
Unlike ITIL, enterprise service management is not a well-defined framework, so we cannot provide a universally accepted list of processes and activities.
But since ESM has its roots in IT service management best practice, we can assume that the service lifecycle concept in ITIL is a good starting point for all organizations that wish to improve the management of their services. The lifecycle is a variant of the "Plan-Do-Check-Act" or "PDCA" cycle, a well-established management method for continual improvement.
The service lifecycle consists of five processes (or "stages"):
- Service strategy: The first stage in the service lifecycle is about setting the service strategy. As service providers, we start with an assessment of our current service offerings, the customers' needs and our own weaknesses and strengths. Based on this assessment, we can define a strategy or road-map for developing a portfolio of services to be offered to our customers.
- Service design: In the second process, we define the expected outcomes of any new or changed services and specify the approach for their implementation.
- Service implementation/ service build: In the third lifecycle stage, we take care of implementing new services (or changes to existing services). This includes acquiring, developing and testing of all required service components, such as the technical infrastructure and supporting services provided by external parties.
- Service operation: Once the services are operational, we need to ensure they are provided efficiently and effectively. This includes handling issues and service requests, performing maintenance tasks, and producing reports on the achieved service quality.
- Service improvement: The final stage is about continual improvement. Within this process, we assess if the services are delivered as promised and try to identify potentials for improvement. This will often lead to the specification and implementation of service improvements.
Of course, this list of processes is not prescriptive, but for most service providers it will be appropriate to introduce at least a basic set of service lifecycle processes, for the lifecycle concept ensures that we never stop learning from past successes and failures - and stay on track in the longer term.
The degree of sophistication required for each process will depend on the nature of the business:
For instance, a business installing equipment in clients' homes will need robust processes for managing configuration information and dealing with failures of these devices, while this may not be so much of a concern for a restaurant chain.
Apart from the service lifecycle processes, most organizations will need a number of additional processes, as recommended in service management best practice. Among these are customer relationship management, financial management, project management, etc. Again, this list of processes is not prescriptive and which ones are needed will depend on the type of business.
YaSM - a framework for enterprise service management
ITIL was developed specifically for the domain of IT services, and what's more, it has grown rather complex over the years. From numerous conversations with our customers we know that, in order to become attractive to providers of non-IT services, the service management guidance has to be easier to understand and less biased towards the management of IT infrastructure.
And here YaSM comes into the picture:
When creating YaSM, our aim was to build a streamlined framework that is not too hard to understand. YaSM, with its simple structure and complete set of process and document templates, is thus a very good choice for organizations that want to get started with enterprise service management.
