(Note: There is additional text attached to this slide that includes the following introductory information from Shelley Row):

"ITS Standards can make your life easier. Your procurements will go more smoothly and you’ll encourage competition, but only if you know how to write them into your specifications and test them. This module is one in a series that covers practical applications for acquiring and testing standards-based ITS systems.

I am Shelley Row the director of the ITS Joint Program Office for USDOT and I want to welcome you to our newly redesigned ITS standards training program of which this module is a part. We are pleased to be working with our partner, the Institute of Transportation Engineers, to deliver this new approach to training that combines web based modules with instructor interaction to bring the latest in ITS learning to busy professionals like you.

This combined approach allows interested professionals to schedule training at your convenience, without the need to travel. After you complete this training, we hope that you will tell colleagues and customers about the latest ITS standards and encourage them to take advantage of the archived version of the webinars.

ITS Standards training is one of the first offerings of our updated Professional Capacity Training Program. Through the PCB program we prepare professionals to adopt proven and emerging  ITS technologies that will make surface transportation safer, smarter and greener which improves livability for us all. You can find information on additional modules and training programs on our web site www.pcb.its.dot.gov.

Please help us make even more improvements to our training modules through the evaluation process. We look forward to hearing your comments. Thank you for participating and we hope you find this module helpful."

Learning Objective #1

Systems Engineering Process (SEP)

Systems Engineering Process (SEP) V Diagram. See extended text description below.

(Extended Text Description: Systems Engineering Process (SEP). A graphic of the systems engineering process (SEP). The main graphic of the SEP is a V-shaped diagram in gradated blue with some additional horizontal extensions on the left and right side of the top of the V shape. Each section is separated with dark blue lines. There is a key at the lower right showing the blue separator lines, and designating them as “Document/Approval.” The left horizontal extension is labeled as “Lifecycle Processes” and include the sections “Regional Architecture” (separated by a white space) to the second section labeled “Needs Assessment,” (blue line) “Concept Selection,” (blue line) “Project Planning,” (blue line) and “Systems Engineering Management Planning.” At this point the sections begin to descend the left side of the V with “Concept of Operations,” “System Requirements,” “High-level Design,” “Subsystem Requirements,” “Detailed Design,” and “Software Coding / Hardware Fabrication” at the bottom juncture of the V shape. Underneath the bottom point of the V shape are the words “Implementation” then “Development Processes” and a long thin arrow pointing to the right labeled “Time Line.” There is a long thin diagonal arrow pointing down along the left side of the V labeled “Decomposition and Definition.” From the bottom point of the V, the sections begin to ascend up the right side of the V with “Unit Testing,” (blue line) “Subsystem Integration,” (blue line) “Subsystem Verification,” (blue line) “System Integration,” (blue line) “System Verification,” (blue line) “Initial Deployment,” (blue line) “System Validation,” and (blue line) “Operations and Maintenance.” There is a long thin arrow pointing up along the right side of the V shaped labeled “Integration and Recomposition.” At this point the sections on the right “wing” of the V are labeled with “Changes and Upgrades” and (white space) “Retirement/Replacement.” Between the V shape there are a series of gray dashed arrows connecting the related sections on each left/right side of the V shape. The first arrow (top) is labeled “System Validation Plan” and connects “Concept of Operations” on the left and “System Validation” on the right. The second arrow is labeled “System Verification Plan (System Acceptance)” and connects “System Requirements” on the left and “System Verification and Deployment” on the right. The third arrow is labeled “Subsystem Verification Plan (Subsystem Acceptance)” and connects “High-Level Design” on the left and “Subsystem Verification” on the right. The last arrow (at the bottom) is labeled “Unit/Device Test Plan” and connects “Detailed Design” on the left and “Unit/Device Testing” on the right. The SEP steps can also be described as parts of phases which are listed across the top of the graphic: Phase -1 (Interfacing with Planning and the Regional Architecture), Phase 0 (Concept Exploration and Benefits Analysis), Phase 1 (Project Planning and Concept of Operations Development), Phase 2 (System Definition and Design), Phase 3 (System Development and Implementation), Phase 4 (Validation, Operations and Maintenance, Changes and Upgrades), Phase 5 (System retirement/replacement). Numerous cross-cutting activities are listed vertically to the left of the V diagram: Stakeholder involvement, Elicitation, Project Management Practices, Risk Management, Program Metrics, Configuration Management, Process Improvement, Decision Gates, Trade Studies, Technical Reviews, and Traceability. Phase 0 (Concept Exploration and Benefits Analysis), Phase 1 (Project Planning and Concept of Operations Development), Phase 2 (System Definition and Design), Phase 3 (System Development and Implementation), Phase 4 (Validation, Operations and Maintenance, Changes and Upgrades), Phase 5 (System retirement/replacement).

Typical Scope of Device Vendor

Typical Scope of Device Vendor. See extended text description below.

(Extended Text Description: Typical Scope of the Device Vendor. The “V” portion of the SEP diagram (described on the Systems Engineering Process (SEP) diagram above) with shading on it that shows that the device vendor’s role covers: 1) The detailed design, except for the portion covered by the area previously highlighted in slide 27, indicating that they do not need to duplicate the work of the standard; 2) All of the software and hardware development; 3) All of the unit testing; 4) All of the subsystem integration and verification. The shading is darker as you move down the V indicating that the more detailed processes are largely hidden from the view of the agency, whereas the shading of the subsystem verification is barely existent indicating that this step is done with the presence of the agency.)

 

Slide 35:

Learning Objective #2

Typical Scope of System Integrator

Typical Scope of the Systems Integrator. See extended text description below.

(Extended Text Description: Typical Scope of the Systems Integrator. The “V” portion of the SEP diagram (described on the Systems Engineering Process (SEP) diagram above) with shading on it that shows that the system integrator’s role covers: 1) The detailed design, except for the portion covered by the area previously highlighted in slide 27, indicating that they do not need to duplicate the work of the standard; 2) Portions of all prior steps starting at the same point in time (i.e., the boundary of the shaded area forms a vertical line against the slanted V with each previous stage receiving less and less shading); 3) The software and hardware development; 4) The unit testing; 5) The subsystem integration and verification; 6) The system integration and verification; 7) The initial deployment; 8) The system validation. The shading is darker as you move down the V indicating that the more detailed processes are largely hidden from the view of the agency, whereas the shading of the higher level steps is minimal indicating that these steps are highly visible to the agency.)

Benefits of SEP

Benefits of SEP scatter graph. See extended text descripion below.

(Extended Text Description: Benefits of SEP. A scatter chart diagram depicting the relative amount of cost overrun on projects against the percentage of the project cost spent on systems engineering effort. The scatter points show that projects spending less than 4% of the budget on systems engineering effort can range from coming in right at planned project cost to being more than double planned project cost with a mean near 1.5 times the planned project cost. When systems engineering effort is increased to 8%, the range is nearly the same, but the mean is closer to 1.3 times the planned project cost. With 12% systems engineering effort, the range of data points is concentrated to 0.8 times planned project cost to 1.4 times planned project cost with a mean of about 1.1 - 1.2 times planned project cost. Data points beyond a 15% systems engineering effort are all located at almost exactly 1.0 times planned project cost.)
