Acquisition Test 2 Flashcards
What is Systems Engineering?
Designing & developing systems products and processes to satisfy customer needs
Transforms needed operational capabilities into an integrated system design through concurrent consideration of all Lifecycle needs.
Why is Systems Engineering important?
~85% of life cycle costs are determined by requirments & design decisions made early in the Acquisition process.
What does SEP produce? What does it not produce?
A description of system parameters (what it must do; how well; how often; under what conditions; with what contraints).
It does not create the design.

Performance-Based Specifications & Standards
Output from previous SEP iterations
Constraints (Operational Environment, Laws/Regs)
What is the purpose of the SEP Requirements Analysis?
Develop functional & performance requirements:
What it must do
How well
What environment
Range, Accuracy, Lethality
Quantity & Quality
Survivability
Supportability/Availability
Contraints:
Operational Environment
Laws, Requlations
What is the purpose of the SEP Requirements Validation?
- Ensures requirements baseline meets user’s expectations & satisfies project & external constraints.
- Traces each requirement to corresponding functions
- Ensures each function addresses at least 1 requirement.
- Resolves conflicts between requirements & functions
What is the purpose of Functional Analysis in the SEP?
-Translate validated requirements baseline into a functional architecture.
- Allocates functional requirements
- Allocates performance requirements
- Functional descriptions
-Results in Functional Architecture
What is the purpose of Functional Verification in the SEP?
- Verifies the functional architecture satisfies all of the validated requirements.
- Traces physical & software elements to requirements
- Verifications: Inspection, Demonstrations & certifications, Simulations & Analysis, Testing
What is the purpose of Synthesis in SEP?
- Defines physical architecture
- Defines interfaces
- Produces critical system data
- Physical descriptions
-Results in physical architecture
What is the purpose of Design Verification in the SEP?
- Ensures requirements of the physical architecture are traceable to the verified functional architecture.
- Verifies that the design satisfies the validated requirements baseline.
- Traces each function to corresponding physical or software element
- Ensures each physical or software element addresses at least one functional element.
- Resolves conflicts between functions & physical architecture
What is the purpose of the Systems Analysis in the SEP?
- Resolves conflicts
- Decomposing & allocating requirements
- Conduct trade studies & assessments
- Conduct effectiveness analyses
- Managing risks
What are Market Surveys in Systems Analysis?
- Answers the question “Is it doable?”
- Identifies technology & software maturity
- Identifies potential sources & degree of competition
- Provides insights to high risk areas & cost drivers
What is the purpose of Control in SEP?
Manage & document system engineering activites:
- Risk & data management
- Configuration management
- Interface management
- Performance progress analyses
Identify SEP Outputs.
- Output varies depending on stage of development
- Decision data
- System architecture
- Performance specifications & baselines
- Process outputs from one SEP iteration may be process inputs for the next iteration
Define WBS
Work Breakdown Structure is a tool to allow PMs/Contractors to break large tasks into smaller sub-tasks.
- Relates tech elements of work to be accomplished to each other & the end product.
- Can be broken down to any level of interest.
- PMs develop the top 3 WBS levels
- Contractors may develop lower WBS levels.
Name 5 purposes for using a WBS.
Organizational:
- Road map for management of the program.
- Assignment of IPTs
Technical:
- Tool to design & track technical work.
- Relates to SOW & CLIN development
- Tool for Risk Assessment
Business:
- Provides structure for Budgets & Cost Estimates
What do the first 3 levels of the WBS consititue? Who determines them?
Developed by the PM, which encompasses the Objectives of the entire Program.
Level 1: Defense Material Item (Ex: Aircraft System)
Level 2: Major Elements (Ex: Air vehicle, data, training, facilities)
Level 3: Subordinate Elements (Ex: air frame, propulsion, flight software)
What are 3 determining factors on how low a contract WBS goes?
Risk, cost, & complexity.
Contractor will be required to provide status report updates at lower level WBS if it involves high risk, cost & complexity.
What is the lowest level of a complete Contract WBS?
The Control Account: from a PM’s perspective
What is Modular Open Systems Architecture?
A system designed to readily accept future technical upgrades, modifications, or enhancements during its Life Cycle.
Includes: Software, Hardware, & Subsystems
What are 3 benefits & challenges with Open Systems Architecture?
Benefits:
- Reduced LCC (future cost savings)
- System fielded faster
- Easier technology insertion
- Better performance
Challenges:
- Lack of supplier control
- Lack of technical data
- Ongoing standards management
- Validation of compliance
What is Total Ownership Cost (TOC)?
At Individual System Level TOC = Life Cycle Cost
At DoD Level TOC = LCC plus
Post deployment O&S incurs 65%-80% of system’s LCC
What is TOCs relationship to SEP?
LCC/TOC can be directly traced to the SEP as the system parameters are determined by user requirements & application of the SEP.
What is Operation & Support Cost?
Resources required to operate & support a system, subsystem, or major component during its useful life.
-Resources may include: facilities, training, fuel, ammo, manpower requirements, repair parts, etc.
At what point in the acquisition cycle is LCC “locked-in?”
Once Post-Critical Design Review Assessment (CDRA) is approved during the Eng, Manufacturing, & Design phase.
