Systems Engineering Process Design Approach

The following are guidelines we use to bring an operational concept into reality. These steps are based on a system engineering design approach.

1. Defining customers’ requirements (deficiencies and needs)
What are the customers’ needs?
What does the customer want the system to do?
*MOST IMPORTANT*
 
2. Conceptual design process
a. Feasibility study - alternative technologies
b. System operational requirements (including human factor)
c. System maintenance concept (must be designed for maintainability)
 
3. Preliminary Design
a. System  Functional Analysis
 System operational functions block diagrams
 Maintenance functions (procedure for maintaining system)
 
b. Preliminary Synthesis and Allocation of System Requirements
 "Combine and structure parts/elements of an item..." to form a functional entity
 Allocation of system support requirements
 Allocation of performance factors, design factors, and effectiveness
 
c. System Optimization Analysis
 System/sub-system tradeoffs and evaluation of alternatives
 
d. System Synthesis and Definition
 Preliminary design - modification and structuring of alternative design configurations
 Development, test and evaluation of engineering modes
 
4. Detail Design
a. System Detail Design
 Detail design of prime system elements (Description of prime system elements)
 Detail design of system support elements (Engineering design drawings)
 Design analysis and evaluation
 Design review (Requirement checklist)
 
5. System Prototype Development
 Development of system prototype model
 Development of system logistics support requirements
 
6. System Prototype Test and Evaluation
 Test preparation
 Testing of prototype system and equipment
 Test reporting
 System analysis and evaluation
 Modification for corrective action
 
7. Production and construction
 
8. System utilization and life-cycle support
 
9. and lastly system retirements

Deliverables:
1. Documentation
a. System Design Document
b. System Standard Operating Procedures (SOP)
c. Systems Password
d. Systems Model, Serial Number, Barcode
e. Systems Contract support Number
2. Timetable
