# 2-8 Why Integrate Human Factors?

**Important HF Questions to Address During Acquisitions.** The [<span style="color: rgb(53, 152, 219);">Human Factors AMS Lifecycle Checklist</span>](https://faa.switchboxinc.com/published/ams_lifecycle_checklist.xlsx) identifies:

- HF questions that need to be considered as part of the Acquisition Management System (AMS) process
- The AMS stages at which these questions should be addressed
- FAA documents within which the HF findings based on these questions should be incorporated

A sample of these HF questions includes:

- Are human capabilities and limitations considered as part of the total solution?
- Has a functional analysis been conducted to determine information flow and processing required?
- Has a front-end analysis adequately identified the human performance issues for test planning?
- Does documentation identify the specific human factors tasks and activities that must be planned and executed to support timely design, development, and implementation?
- Do the human factors requirements meet the appropriate specifications or standards, including the <span style="color: rgb(53, 152, 219);">[Human Factors Design Standard (HF-STD-001B](https://hf.tc.faa.gov/publications/2016-12-human-factors-design-standard/))</span>?
- Have product functions been properly allocated between the hardware, software, and the human?
- Have the human factors implications of each alternative been determined for their impact on human-system performance, cost, benefits, schedule, interfaces, and technical risks, and then used to select alternatives?
