Epic Environments

Epic is not one system. It is a set of copies, called environments, each with a job. Most look identical once you are logged in, which is exactly why the label on the desktop icon matters. This page tells you which ones you will actually use, what the rest are for, and how a change travels from an idea to the live chart.

The environments you will use

Every Freeman provider works in PRD. For training you also touch CRE or DEMO. A smaller group opens POC and TST for specific jobs. You may not see a separate desktop icon for each; the Epic Hyperspace icon opens a menu of the environments you have been granted.

Reading the desktop icon

Epic Hyperspace desktop icon, redEpic Hyperspace desktop icon, white

Most providers have one Epic icon on the desktop: Epic Hyperspace, in either the red or the white style shown here. It opens a menu that lists every environment you have access to. Pick PRD for patient care. If you have been granted CRE, DEMO, POC, or TST, they may appear in the same list.

Personalize your settings in PRD during User Settings Lab. Settings made in PRD persist through go-live and stabilization; settings made anywhere else stay behind.

The environment name also shows in the Hyperspace title bar. If you are documenting on a real patient and it does not say PRD, stop and switch.

Haiku and Canto point only at PRD. The QR codes on the Haiku and Secure Chat Setup page are PRD codes, not training codes.

How a change reaches the live chart

This is why a fix you asked for does not appear the same afternoon. Every change, from a new order set to a SmartPhrase in a shared template, follows the same path so it can be reviewed and tested before it touches real patients.

Analysts build in POC and move it forward with Data Courier. Nothing is built directly in PRD. PRD is copied to SUP every night and to RPT and DR continuously, so those three always look like the live chart.

If you are reviewing an order set in Round Table, you are looking at POC. The version in PRD will not change until the build has passed through TST. The OPA & Order Set Requests page walks through the request side of that process.

Epic-led training strategy

Epic offers two training models. Under the customer-led model an organization builds and maintains a full set of classroom environments. Freeman chose the Epic-led model: pre-course work runs on training.epic.com/EUT, and all Freeman training happens in two Freeman environments, CRE and DEMO, that carry Freeman's own build.

EPIC-LED TRAINING STRATEGY (FREEMAN'S MODEL)
PRE-COURSE WORK

Your pre-course assignments run in Epic's own online training environment. Everything after that, including your class, happens in Freeman environments with Freeman's build.

CLASS AND PRACTICE
CRE and DEMO

Training and hands-on practice happen here, in Freeman's own build with training patients. CRE is also where department reviewers check order sets and note templates before go-live.

GO-LIVE
PRD

Created from TST about four months before go-live. October 24 is the first day real Freeman patients are charted here.Real Freeman patients have been charted here since October 24, 2026.

Freeman does not have a Playground (PLY) environment. Practice after class happens in CRE or DEMO when a session is scheduled, and in PRD with test patients only when your trainer or the Command Center tells you to.

Where real patient data lives

Protected health information is limited to PRD, DR, RPT, SUP, REL, PJX, and MPE. Everything else holds test or training patients. Two habits follow from that: never enter a real patient's information into a test or training environment, and treat anything you see in SUP or REL as real, because it is a copy of the live chart.
