Terms & Definitions

Term	Definition
MUST	This word means that the definition is an absolute requirement of the specification.
MUST NOT	This phrase means that the definition is an absolute prohibition of the specification.
WILL	This word means that the definition is an absolute future requirement of the specification.
WILL NOT	This phrase mean that the definition is an absolute future prohibition of the specification.
SHOULD	This word means that there may exist valid reasons in particular circumstances to ignore a particular item, but the full implications must be understood and carefully weighed before choosing a different course.
SHOULD NOT	This phrase means that there may exist valid reasons in particular circumstances when the particular behavior is acceptable or even useful, but the full implications should be understood and the case carefully weighed before implementing any behavior described with this label.
MAY	This word means that a requirement is truly optional. The developer may choose to include the item based on the needs of their design.

Use Case Level Criteria

When designing use cases, it is important to maintain a consistent approach to determining at which level use cases are placed when they are authored. The granularity of the use case directly relates to its implementability, so maintaining a leveling scheme will insure that use cases are implemented, tested, etc. at a consistent level. In alignment with this, we will maintain the following use case leveling criteria:

Global statement
Example: manage patient's health
Use Case Level 0: most general, high level business process
Example: treat this patient for cancer
Use Case Level 1: next level of business flow, such as inter-department level
Example: treat this patient for cancer by using diagnostics, education, treatments, etc.
Use Case Level 2: specific enough to drive major model dimensions (static/information model, behavioral model, governance model, etc.) and can include some exception conditions
Example: treat this patient for cancer by ordering these lab tests, evaluating the results, customizing a treatment or treatment plan to specifically address concerns
Use Case Level 3: includes details of each exchange of information, as well as assumptions about system boundaries
Example: treat this patient for cancer by ordering these lab tests in the caEHR system
i. find the patient, if new add patient, if not check for update
ii. create request(s) for testing for patient, then evaluate the results,
ii-a. read the faxed copy of the result or
ii-b. receive notification in Provider email that a result is ready for viewing, etc...
Use Case Level 4: project-specific solution for exchanges detailed in use case level-3 (could be MSG, SOA, or both)
Example:Standard Process Flow
1. Provider Refers Patient for Cancer Treatment
2. Provider and Patient have an encounter
3. Provider evaluates Patient's condition, treatment plan, current statistics, requests diagnostics
4. Provider updates treatment plan
5. Patient is treated, outcomes documented
6. Flow returns to any of the above steps or patient is released from cancer treatment

Assumptions and Dependencies

Usability

The user interface shall be designed for ease-of-use by the designated end-users, shall use terms common to the user's normal business environment, and shall require little to no additional training on the system. Drop down menus, Google-like searches, and tooltips should be used wherever appropriate.

Accessibility

The user interface should be accessible via a web browser.

General Assumptions

Following is a list of basic assumptions:

Federated Discovery Services: Knowledge Repository Services will be distributable and discoverable in a federated manner
Security Considerations: services and underlying data will be secured using the caBIG security architecture
Subscriptions/Notifications: services requiring subscription and notification functionality will be enabled by the caBIG pub/sub architecture
ISO 11179 Ed 3: the Knowledge Repository will comply with ISO 11179 Ed 3 specifications. See here for our analysis.
Ability to have non-administered items: the Knowledge Repository will provide for non-administered items in the ISO 11179 notion
Duplication/identification: in compliance with the Federated Discovery Services assumption, reference of data, data duplication, and unique identification of data will be handled

Dependencies

TBD

ID	Requirement
QS-1	The system must be adequately validated during the system development lifecycle.
QS-10	The system must provide the functionality to generate and manage accurate data records during the development processes.

Usability

In design, Usability is the study of the ease with which people can employ a particular tool or other human-made object in order to achieve a particular goal.

ID	Requirement
US-1	An intuitive user friendly graphical user interface must be developed.
