The objective of this subtask is (0 assure correspondence between these two pieces of software--there must be logical consistency between the two in terms of water rights administration and project operation assumptions. These issues of correspondence will be identified through the review of the scope and current progress of work on each piece of software and through a joint meeting between the Sponsors Committee, the USBR technical development staff, and the Hydrosphere technical development staff. If necessary, a follow-up meeting will be scheduled to resolve any outstanding issues of inconsistency. Thereafter, periodic checks will be made to identify and resolve any changes in the scope and direction of work on each piece of software. Subtask 1.3.g: Define Target Computing Environment The objective of this task is to define the type of computer hardware that will be necessary to effectively use the Planning Model. One consideration in this regard is the types of hardware systems currendy owned by the various members of the Sponsors Committee. Another important consideration relates to the desired operation of the model as discerned during Subtasks 1.3.a through 1.3.f above; it may be that the "lowest common denominator" of existing computer hardware is incapable of supporting many of the types of simulation and user interaction operations that are desired by the Sponsors Committee. The tradeoff then would become one of giving up model functionality to avoid costs of upgrading hardware. The definition of the target computing environment will be accomplished through a survey of existing Sponsors Committee hardware, a survey of current costs for upgrading those systems to varying degrees, and a tradeoff analysis that compares proposed Planning Model functions to the capabilities of various hardware systems. Subtask 1.3.h: Prioritize Needs The foregoing subtasks in the needs analysis will have identified a host of desired Planning Model functions and features. The objective of this subtask is to summarize and prioritize those functions and features in light of available project resources and the target computing environment identified in Subtask 1.3.f. This prioritization will involve considerable discussion among the Sponsors Committee with Hydrosphere providing supporting infonnation on development costs and hardware requirements. The result of this task will be the clear definition of the functions and features to be incorporated into the Planning Model.
