The scientific method is a system for acquiring knowledge based on the collection of data through observation, experimentation and the integration of previous knowledge. This is followed by the formulation and testing of hypotheses resulting in new knowledge and possibly the correction previous knowledge. From a system design perspective the scientific method is a well defined system, use cases are abundant, requirements are readily accessible and guiding principles are fully articulated. With advancement of technology new implementations emerge to support and enable science. We are now in the age of Virtual Observatories where distributed data are coupled through services and well-defined metadata. The paradigm is one in which information is sought and retrieved just in time for its use. We discuss a system model for a Just In Time Information (JITI) system that addresses the clearly identified needs of scientists. It includes tasks such as coordinate system conversion, file format transformation, subsetting, aggregation, and rendering. We also discuss the discovery needs of the scientist which range from the initial discovery of available resources to complex scientific queries. Overall the system is composed of a collection of small services which are tied together on a task-by-task basis, similar to that of a workflow, but with distributed and loosely coupled components. In a JITI system each service is invoked as needed with unique resource identifiers passed as the common reference thread that enables the service integration. The services that are part of a JITI system can be utilized in a number of ways to implement portals, search engines, aggregators, and mash-ups. JITI-like systems are emerging in the Virtual Observatory communities. We look at NASA's Virtual Magnetospheric Observatory, the Heliophysics Event List Manager (HELM), Europe's HELIO project and Canada's CSSDP project as examples.
