Highlights
SERVICE ORIENTATION IN BUSINESS ARCHITECTURE
"Service-orientation: viewing an enterprise, system, or building block in terms of services provided and consumed." (TOGAF).
The “Open Agile Architecture“ standard from The Open Group defines "service" has having two meanings. One definition is "An encapsulated component that delivers outcomes through well-defined interfaces.”
This article favors the other definition: “An act performed for the benefit of another." Such a service may deliver information or materials, or make a product or facility available for a period of time.
SERVICE CONTRACTS
The parties who request and/or consume business services include not only customers (who pay for services provided), but also prospects (who make enquries, but may never become customers), suppliers (who invoice us for services we consume), legislators (who request evidence of compliance), and others.
The general principle is to define a service from the outside, in terms of what it requires and delivers, rather than the activities, actors and resources needed to complete it. For example, the services provided by a butler to a gentleman may include: -- Iron shirt - triggered by a request, delivers a creaseless shirt. -- Make breakfast - triggered by a time event (08.00 hours), delivers food. -- Polish shoes - triggered by a state change event (shoes dirty), delivers shiny shoes.
The act of delivering polished shoes is definable in a service contract that includes some or all of the following information: -- trigger (a request, time event or system state change), -- entry conditions (inputs and preconditions), -- exit conditions (outputs and post conditions, results or effects) -- non-functional qualities (speed, throughput, availability, price, etc.). You might add the value delivered by a service - whatever you mean by that.
This service contract makes no reference to the process and resources needed to complete the service. Moreover, it does not mention the service provider or consumer.
Note: a service-level agreement (SLA) document is a different kind of contract (between identified parties) that usually covers several or many discrete services of the kind discussed above, which may be named but not defined in detail.
SERVICE PARTICIPANTS
A service contract may be defined independently of the parties accountable for requesting, providing or consuming the service, and completed in various ways. For example, the delivery of a pizza in response to an order may be distributed between actors, who may each invoke services from other parties.
Service providers may compete to be the fastest, cheapest or best. Business directors can select from alternative business service providers, and govern them against an SLA document that defines services without constraining how service providers work. (Having said that, constraints on how they work can be specified service contracts.)" https://lnkd.in/g-xk2Tcb
Service-oriented EA
"In structured analysis approaches of the 1980s, Business Functions, Applications and Technologies were seen as active or dynamic components in a network of components that interact by sending and receiving data flows (each containing a message, file or other kind of data structure), to produce desired effects (state changes and outputs).
The term interface was used for a data flow exchanged between sender and receiver components.
In object-oriented approaches of the 1990s, Business Functions, Applications and Technologies were seen as interacting in network of objects that provide and require methods or operations - each being an act performed for another.
The term interface was now used for a declaration of operations that an object provides, or requires, here called services.
Not all object-oriented software architecture principles scale up to enterprise architecture, but still, TOGAF v10 takes a service-oriented approach, defining service-orientation as "viewing an enterprise, system, or building block in terms of services provided and consumed."
TOGAF uses the term interface ambiguously, for a data flow, and for a service portfolio, defined as "a collection of services [or] interface definition [used] to define the requirement for a building block or system."
ArchiMate defines a service as the external view of a unit of behavior. The contract for a service encapsulates (hides) the particular activities and resources needed to deliver it. So, a service can be completed in different ways, by different providers, who might compete to be the fastest, cheapest or best in some other way."

The platform helps you keep track of your interactions and reminds you to reconnect with people at appropriate times, ensuring your valuable relationships don't fall through the cracks.

Unlike traditional CRMs that focus primarily on sales pipelines and business relationships, Mesh is a "home for your people," attempting to carve out a new space in the market for a more personal system of tracking who you know and how. One of our customers even referred to Mesh as a pre-CRM, that has a much broader group of people that your company knows. Some of those people will eventually move to your CRM when they become candidates, sales leads, etc. Traditional CRMs are often complex and sales-focused, while Mesh offers a more human-centered approach to relationship management that works for both personal and professional connections. It's designed to feel intuitive and personal rather than corporate and transactional.
