12.2 Executing the POE Research Plan, Independent Evaluation & Finalizing the Business Case
Key Takeaways
- CHD's exam content outline says research after occupancy assesses the effectiveness of design solutions, tests or confirms theories, and contributes to the industry knowledge base.
- Executing the research plan includes identifying the team, prioritizing topics and hypotheses, reviewing existing evidence, setting timeframe, schedule, and budget, choosing methods, securing resources and funding, and obtaining owner and IRB approval.
- An independent third-party evaluation can add objectivity and credibility but brings added cost and less familiarity with the project's intent.
- The outline calls for finalizing the business case after occupancy so actual results document the return on investment.
- Iterative post-occupancy evaluations re-evaluate ongoing systems and operations to support continuous improvement.
Executing the POE Research Plan, Independent Evaluation & Finalizing the Business Case
EDAC Core Concept: Domain 6 of CHD's current Detailed Content Outline—Post Occupancy/Evaluation—treats evaluation as a planned research activity, not a courtesy survey. It asks candidates to explain the value of an unbiased POE, how to execute the research plan, the benefits and drawbacks of an independent third-party evaluation, why the business case is finalized after occupancy, and why iterative POEs support continuous improvement.
Why Research Continues After Construction
The outline notes that research informs design decisions during design, and that it also plays a significant role after construction and initial occupancy by helping teams:
- Assess the effectiveness of design solutions
- Test and/or confirm theories
- Contribute to the industry knowledge base
A post-occupancy evaluation (POE) is therefore both a management tool for the owner and a contribution to the field.
Executing the Research Plan
Before collecting data, the outline asks the team to reiterate and reaffirm the owner's goals and determine the role of the project team in conducting research. It then lists the steps for executing the research plan:
| Step | What It Involves |
|---|---|
| Identify the research team | Researchers, clinical and operational partners, data analysts, and design representatives |
| Narrow the research focus | Prioritize research topics and select the hypotheses to be studied |
| Conduct a literature review and evaluate the level of existing evidence | Confirm what is already known so the study adds value |
| Establish the research timeframe, schedule, and budget | Match data collection to stabilization and seasonal needs |
| Determine the methodology | Quantitative, qualitative, or mixed methods consistent with the baseline |
| Define necessary resources | Staff time, instruments, data access, analysis support |
| Explain potential benefits and drawbacks of an independent third-party evaluation | Decide who will lead or verify the evaluation |
| Obtain funding | Confirm the research budget is available |
| Obtain approval from the owner and the Institutional Review Board | Secure organizational permission and ethical review where required |
Then the team collects data and documents how the data were collected, and documents empirical findings and conclusions. Documenting collection methods matters as much as the results: without it, others cannot judge reliability or repeat the study.

Independent Third-Party Evaluation: Benefits and Drawbacks
| Benefits | Drawbacks |
|---|---|
| Objectivity and credibility — findings are less likely to be seen as self-promotion by the designer or owner | Added cost for the evaluator's time and travel |
| Reduced conflict of interest — the evaluator has no stake in the design's reputation | Less familiarity with the project's history, intent, and trade-offs |
| Methodological expertise — experienced researchers design and analyze studies well | Time and access needs — evaluators must learn systems and obtain data access |
| Candid feedback — staff may speak more openly to an outside party | Data-sharing and confidentiality agreements must be negotiated |
Many projects use a hybrid model: an independent researcher leads data collection and analysis while the design team and owner explain the design intent and help interpret findings. The goal is an unbiased POE, whose value lies in credible results that can guide decisions and be shared with the field—including results that disappoint.
Finalizing the Business Case After Occupancy
The outline asks candidates to explain why finalizing the business case should be completed after occupancy to document the return on investment. Earlier business cases rely on projections: estimated savings from fewer falls, lower turnover, or reduced energy use. After occupancy, the team can replace projections with measured results:
| Business-Case Element | Before Occupancy | After Occupancy |
|---|---|---|
| First (capital) costs | Estimated, then documented at construction completion | Final actual costs |
| Operating savings or costs | Projected from evidence and baseline | Measured from post-occupancy data compared with baseline |
| Payback / return on investment | Forecast | Calculated from actual results |
| Assumptions | Stated | Tested, confirmed, or revised |
A finalized, evidence-based business case builds credibility with the board and executives, informs future capital decisions, and gives other organizations realistic numbers.
Iterative POEs and Continuous Improvement
The outline encourages teams to consider performing and documenting iterative post-occupancy evaluations to continuously re-evaluate ongoing systems and operations in support of continuous improvement. A first POE after stabilization may reveal problems that operational changes can fix; a later POE can check whether those fixes worked and whether benefits persisted.
| Evaluation Round | Typical Focus |
|---|---|
| Early check (first months) | Urgent operational fixes, safety issues, and wayfinding or control problems—not formal outcome testing |
| Formal POE (after at least six months) | Hypotheses compared with baseline using the same measures |
| Follow-up POE (a year or more later) | Persistence of outcomes, effects of operational changes, and lessons for the next project |
Worked Scenario: From Projection to Documented Return
A hospital installed ceiling lifts in every room of a new orthopedic unit. The preliminary business case projected fewer staff lifting injuries and lower related costs. Before occupancy, the team reaffirmed the owner's goals, selected the injury hypothesis, confirmed that the baseline used the same injury definitions, and obtained IRB determination for staff surveys. An independent researcher from a partner university led the analysis, while the design team explained the lift layout and training plan.
Twelve months after stabilization, recorded lifting injuries on the unit fell compared with baseline, but surveys showed that night staff used lifts less often because slings were stored far away. The finalized business case documented the actual change in injury-related costs, and a follow-up POE after moving sling storage checked whether night use improved. The findings were shared internally and presented at a healthcare design conference.
Exam Watch: High-Yield Traps & Pitfalls
[!WARNING] Trap 1: POE ends the research. POE findings assess effectiveness, test theories, and feed the industry knowledge base and future projects.
[!WARNING] Trap 2: Third party is always better. Independent evaluators add objectivity, but cost, access, and familiarity trade-offs must be weighed.
[!WARNING] Trap 3: The business case is done at construction documents. The outline calls for finalizing it after occupancy with actual results.
