This Environment exists in the following Working Area(s):
The External Environment comprises facilities that are used to support business functions used by ArchiSurance, but not provided nor managed by ArchiSurance (administrative responsibility).
ArchiSurance uses providers of external services (so called "Cloud services"). ArchiSurance uses these external services for support of innovative projects and sales events. Although ArchiSurance does not manage these facilities itself, it should impose proper Quality Demands on the service offerings of external/cloud providers in order to safeguard important business processes.
The quality demands of this Environment are:
|QA Group||Quality Attribute||Value||Rationale|
|Flexibility||Adaptability||NS||is not an issue for ArchiSurance, but for the provider|
|Scalability||NS||Flexibility in resources consumed is one of the most important drivers to use these kind of services. ArchiSurance uses these services to thrive innovation and support sales events, causing peak utilization.|
|Maintainability||Manageability||NS||is not an issue for ArchiSurance, but for the provider|
|Accountability||MP||When using external resources, service providers should supply "pay per use" as one of the drivers to obtain these services externally. Business units incurring them should be charged according to the use they make of these services, in order to put a brake on intractable consumption of these offerings.|
|Reliability||Availability||Medium||Providers should at least take care of a "Medium" availability level, for sales events a "High" availability level is advisable.|
|Integrity||NS||is not an issue for ArchiSurance, but for the provider|
NB: Only the two or three most important Quality demands for this environments are rated here. The purpose of this listing is to generally characterize an Environment in terms of Quality demands.
