Modes of Differentiation

veryard projects > so > differentiated services > differentiation

Differentiation involves providing a different service according to the context. Ideally the interface remains the same, but with some variation in the content or quality or commercial terms of the service.

When it works properly, service differentiation combines the economic and technical benefits of generalization with the economic and technical benefits of specialization. It also provides a new angle on security (differentiated security).
Service Differences
Content Data Workflow
Data Quality Precision/Accuracy/Granularity Latency/Timeliness Scope/Horizon
Security Access Operation-Specific/Object-Specific CopyProtection/OpenSource
Technical Quality Speed/Response Performance/Throughput Reliability/Availability
Cost/resource usage
Control Differences
Price Paid
Customer Type Gold/Regular
Transaction Type Voice over Data, StolenCardReport versus RegularTransaction
Customer/Transaction History e.g. Recent Complaint, Previous Claim
Connection Type High/Low Bandwidth, Inside/Outside Firewall
Software Type Java-enabled versus text-only browser
Security Level Customer Employee Privileged Administrator

and other possibilities ...

Control Mechanisms
Separate policy or workflow layer
Service tokens
Policy blackboard
Multiple implementations or separate plug-ins
Hand-coding within each component

these options are presented in descending order of preference
