8.1. Conversion from prototype to full system

The conversion of the prototype into a fully functioning system would take between one to two years of intensive development (the `completion stage'), and from then it would operate as a more settled `production system' but one still requiring substantial regular inputs both in terms of content and updating of software and hardware (the `production system' stage). A `prototype maintenance stage' until any follow-on RETA commences must also be considered.

If the Bank decides to develop a full system, this does not mean that the host facilities for the prototype, or any of the software used for the prototype, will be used. Functional equivalents could be implemented with different software on another host site. That is a matter for the Bank. Both alternatives are considered in the options below.

8.1.1. Completion stage

The main components of the completion stage, if it was developed from the approach taken in the existing prototype, would be: The time within which this `framework' for DIAL should be completed is in the range of one to two years, assuming sufficient funding is provided. While it should be possible to complete the bulk of the work within a year, the main unpredictable factor is the difficulty of obtaining and retaining sufficiently skilled staff to work on both the technical and content aspects of the project. This can cause considerable delays, and so a period of at least two years should be allowed. If funds are provided on a one year basis, then provision should be made for the funds to be `rolled over' into the second year to allow for this contingency.

Additional tasks if new host facility and software required

In addition, if a new host and new equivalent software is required, these tasks must be added: It would be prudent to allow at least an additional year for completion if this approach is taken, although if all went well it could take less time than that.

User training

The cost of conducting courses on DIAL use, either via Internet or face to face (as discussed in Chapter 3), is dealt with separately later in this Chapter.

8.1.2. Subsequent years - `Production system' requirements

After the completion stage, the requirements of the system, if it was developed from the existing prototype, would be: It will take some year to assemble a sufficient group of `stakeholders' to pay all of the ongoing production system costs for the DIAL facilities. While this stakeholder model is being developed, some level of funding from the Bank will be needed to complement stakeholder funding.

As noted above, the delivery of user training courses is considered separately.

8.1.3. Prototype maintenance stage

From the completion of the feasibility study until the Bank makes a decision about a completion stage (and, if favourable, work on the completion stage commences), there is an intermediate `prototype maintenance stage' which will last for some months. Assuming that the prototype is to be kept operational so as not to lose the goodwill of existing users, some level of maintenance is needed, at least to the level of ensuring that software is continuing to operate correctly, answers to enquiries, and some continuing addition of content to prevent the facility appearing to be dormant, and to respond to suggestions by users concerning links to be added. Some resources will be needed for this prototype maintenance stage, depending on its duration and the level of maintenance desired. This should require work averaging no more than a day per week. A separate cost estimate has been provided to the Bank in relation to this stage.
