Human Factors Integration (HFI) Issues Log

What is an HFI Issues Log?

An HFI Issues Log is a tool used to identify and record issues and constraints.

The main purpose of the HFI issues log is to outline the impact of each issue, prioritise them and propose a strategy for resolution. The HFI issues log is a live document throughout the project.

What are the Components of the HFI Issues Log?

Issue Log Component	Explanation
Description	An overview of the issues
Issue Category	Can the issues be subdivided into Concerns, Risks or Requirements
Operational process	What operational process do the issues relate to
Option	What acquisition or technology options do the issues relate to
Location	Details of the location or area of impact
Risk Impact	An estimation of the likelihood and impact of the risk – high, medium or low
Consequence	The effect if the issues are not resolved
Action	Suggested actions to resolve the issues
Milestone decision	Dependencies and inputs
Action owner	Allocated responsibility for the actions

How should an Issues Log be developed?

Issues should be identified throughout the acquisition process. However, different stages will provide different types of information. During early stages the issues log will rely on stakeholder consultation and human factors analysis (e.g. task analysis, workload analysis, target audience description, human reliability analysis). At later stages the issues log will rely on trial results, and later from feedback following operational work ups.

At early stages of the acquisition process, issues are gathered relating to each acquisition or system option (a matrix of options vs. human factors integration domains could be used). Each issue should be given a unique reference number and a detailed description. The issue is assessed for the likely impact on cost, time-scale, safety or system effectiveness. It is useful to sub-divide issues into:

• Concerns - issues which cannot be dismissed, and need not be resolved now.
• Risks - key issues representing risk that must be changed.
• Requirements - potential requirements that if accepted, would resolve the issue.

What impacts an HFI Issues Log?

The following topics are required to compile an HFI Issues Log:

• Target Audience Description (TAD)
• Early Human Factors Analysis (EHFA).

Does the HFI Issues Log affect any other processes?

The following lists the dependencies associated with a Human Factors Integration Issues Log, and relevant issues should be placed in the following documents:

• Project Risk and Issues Registers
• Initial Gate Business Case
• Main Gate Business Case
• Supplier approval processes
• System acceptance
• System Requirements Document (SRD)
• Human Factors Input to Combined Operational Effectiveness and Investment Appraisal (COEIA)
• Human Factors input to the Integrated Test, Evaluation, and Acceptance Plan (ITEAP)
• Human Factors Acceptance.

When should a HFI Issues Log be produced?

The HFI issues log should be produced at the start of a project, and incorporated into the Initial Gate Business Case. This will be carried forward through the rest of the acquisition process. The human factors issues are fed into the Project Issues or Risk Registers.

Further Information can be found in the HFI Process booklet [PDF], People in Systems handbook [PDF], Def Stan 00-250 and the Human Factors Intranet site.
