Re: notes from today's call on SOA management

[mpoulin@usa.com]

I was reading the section about service description (for my current work) and found a statement, which I am not sure how to understand:

2004 Recall, more than one service can access the same underlying capability, and this is

2005 appropriate if a different real world effect is to be exposed. Along these lines, one can

2006 argue that different QoS are different services because getting a response in one

2007 minute rather than one hour is more than a QoS difference; it is a fundamental

2008 difference in the business function being provided.

2009 As a best practice, a criteria for whether a service is appropriately scoped may be the

2010 ease or difficulty in creating an unambiguous service description.

To my understanding, the statement "it is a fundamental difference in the business function being provided." is simply wrong! More accurately, it is very programmer's perspective: a business function is the same in USA and in Africa, performed by a laser or a pistol... Function is function. If one consumer wants the business service response in 1 min while another consumer prefers it in 1 hour, function does not change because of this.

QoS makes sense only in the context of the Service Contract.The statement saying that "different QoS are different services" is a nonsense - it is rather a good or bad service, not a different service (this politically correct service of "different abilities" is a lie to yourself).

Gentlemen – I’m sending my rough notes and will clean up for public posting.

Michael – note definition of service management and agreed preference not to define management service.

 

<notes>

Management is a process of controlling resources in accordance with the policies and principles defined by Governance.

 

Boris: service mgt is the process of managing services.

Rex: OK. People often think of service mgt but it is management of services they are talking about.

Boris: service mgt is the implementation

Rex: part of mgt is service mgt; service mgt in another paragraph

Boris: organizationally no separate mgt layer

Rex: no, is separate layer; service mgt is one responsibility (highly specialized)

 

Boris: service mgt is not management.  Service management is the process of managing the services, not managing the people.

 

Is managing just managing people (Boris)? Ken says no.

 

Rex: service mgt as composite noun is service whose function of mgt.  Separate thing is mgt of service.

Ken: wouldn’t that be mgt service rather than service mgt?

Boris: one of the facets of service mgt is setting up mgt services.

Rex: OK

 

Management service:

Rex: function provided either within service automatically or provided by service provider to manage service actively, i.e. looks at it every day.

Boris: getting into overloaded terms.

Ken: IT or business service?

Rex: mostly IT but monitored by people.  Management of service within service or management from outside.

 

Service management:

Boris: process of proactively monitoring and managing service behavior.

Rex: that can apply to multiple services (stuff above on mgt service was in context of single service)

Boris: process of proactively monitoring and controlling the behavior of a service or a set of services.  Can be manual or automated.

 

Service management is the process – manual, automated, or a combination – of proactively monitoring and controlling the behavior of a service or a set of services.

 

Agreed: let’s not define management service because we run into all the complexities of what is meant by service.
