1. Mission Use Scenarios. Mission scenarios describe the high-level system functionality. Define the mission capabilities expressed as end to end threads. Each thread includes all system components that contribute to the execution of the operation described. For instance, aircraft systems may operate in different geographic theaters with different tactics and strategies. Other systems may operate in a mobile platform (in a car) as well as a fixed platform/location (office).
2. Operational Use Scenarios. Operational use scenarios describe the individual operations that are used to fulfill the mission scenarios. These can be used individually or in sequence to complete the mission scenarios. Define operational scenarios representative of actual system use. These are the sequence of actions taken by the operator and performed by the system for different system operations. The Operational Use scenarios may include high level scenarios as well. Such scenarios consist of the operations of the system as part of a larger system or transactions and interactions with other systems, etc.
a. Startup. Describe how the system is started up.
b. Setup. Describe any setup operations.
c. Normal Operations. Describe operations under normal working conditions.
d. Failure Modes. Describe operations when failure conditions occur.
e. Emergencies. Describe operations under emergency situations.
f. Shutdown. Describe any shutdown operations.
3. Support. Provide a brief statement identifying system support. This can also serve as a section heading for subsections and does not require a text description.
a. Provisioning. List the provisioning requirements and operations to fulfill those requirements.
b. Maintenance. List the maintenance requirements and maintenance operations that need to be performed on the various parts of the system. Identify any special maintenance needs, tools, or equipment. Document all assumptions - who will complete the maintenance and where the maintenance will be performed.
c. Training. Identify the training that needs to be developed to educate personnel on the use and operations of the system. Identify the training type, duration, and format required. Identify any additional, specialized training or prerequisites required for system, operations.

The Human Engineering Systems Analysis Report describes the human engineering efforts conducted as part of the system analysis and present results. The data are used by the procuring activity to evaluate the appropriateness and feasibility of system functions and roles allocated to operators and maintainers.
