Internet Systems Prototyping Service1
The Internet Systems Prototyping Service ISPS was developed in order to lower the risks and costs to online service users. Essentially it is a product testing or proving procedure enabling potentical users or customers to test a prototype of their requirements so as to ensure that critical aspects or signifcant proportions of the conept are practically feasible. ISPS is particularly useful in helping transparency in the process of communincating the systems operational requirements of managers to developers.
ISPS has a radical impact on the cost of ownership of sophisticated online capabilities because it lowers the risks, ensures a clear and early functional specification of customer requirements so that work on the main system is directed to the implementation of a system which will satisfy customer requirements. ISPS-based services are not known to have any time or cost over-runs.
Technical aspects
ISPS modules are selected on the basis of Critical Functional Analysis (CFA) whereby those aspects of critical systems functionality which might be considered to represent an implentation or functional challenge can be separated out and demonstrated as a prototype.
Financial aspects
ISPS has the most effective impact when it is included as a phase of online applications services. This is because it enables customers to make sophisticated demands in terms of systems functionality. When the ISPS is costed into a futures contract the customer can pays a lower monthly fee for the whole service which integrates the ISPS activity.
Innovative impact
The innovative impact of the ISPS approach with the CFA and an appropriate financial package is that online business service can sustain a very high level of affordable inovation so as to respond to specific customer needs. This means the customer learning and innovation curves can advance more rapidly because the rate of expenditure and associated decision risks are lower.
1 Internet Systems Prototyping Service was developed under the Seel-Telesis® applied R&D programme at the Systems Engineering Economics Lab.
