Service Provider Interfaces

By

With the rise of service specialization, sourcing services from multiple service providers has become the normal way of doing business. This approach has allowed service providers to deliver higher quality services and enhanced support capabilities while more affectively utilizing a greater constrained set of resources.  In order for this cost savings and ability to spread risk to be realized an organization must be able to maintain a strong relationship with each service provider.

In order to support the development of strong relationships in a multi-vendor environment, guidelines and reference points (technological, procedural and organizational) between the organization and the multitude of vendors being engaged must be established.  These validated reference points are known as service provider interfaces (SPI).

A service provider interface is a formally defined reference point which identifies some interaction between a service provider and user, customer, process or one or more suppliers.  SPIs are commonly used to ensure that multiple parties in a relationship have the same points of reference for defining, delivering and reporting on services.

SPIs help to coordinate the end to end management of services that are being used to underpin the delivery of business outcomes.  The service portfolio is used to define service specifications.  Since service levels and responsibilities are negotiated at the same time that these relationships are being established, they should include: 
  • Identification of integration points between various management processes of the organization and the various service providers
  •  Identification of specific roles and responsibilities for managing the ongoing systems management relationship with all parties
  •  Identification of relevant systems management information that needs to be communicated to all parties on an ongoing basis
SPIs may also consider overall management, strategy and transition in addition to live services.  This is extremely significant when the service providers involved are part of a strategic initiative to transform an organizations business.

SPIs are defined, maintained and owned by process owners.  However others such as business representatives and service provider process coordinators may be included in creating these definitions.

Four Service Characteristics

By
Recently I came across several articles by researchers and experts that laid out definitions and characteristics of services. ITIL provides us with a definition that can help drive the creation of value-laden services: A means of delivering value to customers by facilitating outcomes customers want to achieve without the ownership of specific costs and risks. An area that ITIL is not so clear is in terms of service characteristics. Several researchers and experts put forth that services have four basic characteristics (IHIP): Intangibility—Services are the results of actions not things. They have no physical presence and represent a logical set of elements. One way to think of service is “work done for others.”  Heterogeneity—Also known as “variability”; services are unique items because of the mechanisms used to deliver services, which is people. Because the people element adds variability, the service is variable. This holds true, especially for the value proposition—not eve...

What Is A Service Offering?

By
The ITIL 4 Best Practice Guidance defines a “Service Offering” as a description of one or more services designed to address the needs of a target customer or group.   As a service provider, we can’t stop there!   We must know what the contracts of our service offering are and be able to put them into context as required by the customer.     Let’s explore the three elements that comprise a Service Offering. A “Service Offering” may include:     Goods, Access to Resources, and Service Actions 1. Goods – When we think of “Goods” within a service offering these are the items where ownership is transferred to the consumer and the consumer takes responsibility for the future use of these goods.   Example of goods that are being provided in the offering – If this is a hotel service then toiletries or chocolates are yours to take with you.   You the consumer own these and they are yours to take with you.      ...

The New Four Ps of Service Management

By
By Donna Knapp For years, people , process , and technology (PPT) was a widely recognized framework for balancing and integrating the components needed to achieve optimal performance and outcomes. In the ITIL v3 Service Design publication, this framework was expanded to the four Ps: people , processes , products , and partners . ITIL 4 has further expanded and evolved this framework to the four dimensions of service management. These four dimensions are collectively critical to the effective and efficient facilitation of value for customers and other stakeholders in the form of products and services. The four dimensions of service management are: Organizations and people Information and technology Partners and suppliers Value streams and processes. These four dimensions represent perspectives which are relevant to the whole service value system (SVS), including the entirety of the service value chain and all ITIL practices. Each ITIL practice is a set of organizational resources base...
