Subject: Re: [soa-rm] Amazon.com and Hurricane Catrina - Service Context? Service "Veneer"?


And the answer, as always, is it depends.  In my example of buying by UPC symbol, it is the same but possibly because the use of the UPC symbol has been expanded.  In the case of having a new service that, let's say, automatically substitutes the charity item number for your choice of a song item number and maybe gives specialized feedback to the consumer saying thank you for responding to the hurricane emergency, I'd say it is a different service. It is derived from the original but I'd say it is different.

P.S. and with this busy hurricane season, we are up to Katrina.

P.P.S.  Another interesting aspect is if you had a computer that hadn't already accepted the iTunes terms and conditions, you were first presented with their click-through agreement before you contribute.  So we also have an interesting reuse of policy and the need to form a contract.

Which raises another question we've been through before in the TC (several months ago): Is it the same service in both cases? That is, are the "normal" Amazon.com order placement service (with credit card info on file, and selectable each time) and this new "hurricane donation" service really the same service?

P.S. Not trying to resurrect a permathread - just tying a recent observation in with a past exchange, to see it in a new light.

Is there also a concept of a service having the same interface but by operating in a different domain (e.g. charity) it acts different for the same interface?  In effect its business contract is changed by a business driver outside of its scope, while its functionality (collecting money) remains the same its imperative is changed by the wider business context in which it now sits.

Apple also did this with their iTunes Music Store: click the link and you order a donation instead of a song.

 

This is why I keep insisting on differentiating between the service and the capability.  The underlying capability is to collect money for a purpose.  The service provides the interface for doing that.  Typically, you invoke the capability through a service that enables you to buy a book (or a song) but a new service invokes that capability (with a new user facing interface for Apple; I haven't checked Amazon) to "buy" a donation.  The power is the capability is reusable by making it accessible through a different service.

 

Now note if I buy something through a service that allowed me to specify the UPC code, I could buy a donation through their existing service with that UPC, i.e. reusing the service for a purpose similar to but different from its original purpose.  In fact, several supermarkets around here do support that because they have little tear-off tablets at the checkout for certain hunger organizations and you can hand the clerk a page for $1, $5, or $10.

 

Many interesting variations and our RM just has to capture the concepts that can describe any of them.  I think I'll mow the lawn and think about this some more.

One thing that I discovered regarding the horrible catastrophe in the Southern US is that Amazon.com enabled people to use its online ordering service to make a donation. One could use the credit card information that Amazon.com already had online to make a donation in what it called "1-Click Donation" (or something similar).

So instead of placing an order for a book, CD, etc., your "order" was your donation, and you could view your "order" online, which (as I recall) would show the amount that you donated.

 

Something that came to my mind is: What would this placing of a "new face" on a existing service be called? Is it a different context for the ordering service? (i.e. in the context of Hurrican Katrina) Is it a "veneer" that was placed on top of the existing service? None of the above?
