EPHT Network
Download as PDF [213 Kb]


The Centers for Disease Control and Prevention (CDC) has selected the Rational Unified Process (RUP) as the framework for all development projects. RUP is a comprehensive, flexible, software engineering methodology created by the Rational Software Corporation. It divides the lifecycle of a project into four distinct phases: 1) Inception, 2) Elaboration, 3) Construction, and 4) Transition. This Vision Document is an artifact from the Inception phase.

The document is organized using a standard document template provided by the CDC Information Resource Management Organization (IRMO) for the CDC development process. It is the first formal document that describes the features that will be proposed to stakeholders to support environmental public health tracking nationwide. Additional discussions will continue with stakeholders to further resolve features of the Environmental Public Health Tracking (EPHT) Network. To develop consensus for a project of this scope, this Vision Document will be reviewed by stakeholders and updated, perhaps many times, until general agreement is reached to move forward with development of the EPHT Network.

The document review process:

  1. The first draft is reviewed by the CDC Environmental Health Tracking (EHT) Branch;
  2. The document is reviewed by the EPHT Network workgroup members;
  3. The document is reviewed and approved by the EPHT Network Change Control Board (CCB).

CCB members are listed in the Appendix. Future versions of this document may be drafted as necessary.
