5 reviews for this course

3. Design Reviews Do we understand the requirements?
Do we understand the essential interfaces?
Do we have all the necessary functionality?
Are the requirements allocated & testable?
Does the design meet the requirements – feasible, maintainable, safe, reliable?
What are the TPMs we need to track?
What are the RISKS & how do we mitigate?
Are we ready to TEST?
Did we build it right?
Did we build the right system?
The system must be OPERATIONALLY SUITABLE & OPERATIONALLY EFFECTIVE

4. Typical Design Reviews
Most reviews can also be performed at the system, subsystem, product, component, and assembly or part levels.
System Requirements Review
System Functional Review
System Architecture Review
Preliminary Design Review
Detailed (Critical) Design Review
System Test Readiness Review
System Validation Review
Production Readiness Review
Shipping Readiness Review
What is the FOCUS?
Requirements being satisfied by the defined solution set, within the architecture boundaries and constraints defined by management/contract and technology readiness.

5. Phase Gates Purpose Technical focus Subcontractor/Suppliers
Management oriented
Cost & Schedule + RISKS
Plan to get to the “next” gate
Technical focus
Have we done the right things
Do we have the right mix of disciplines
Do we have the right technologies
Where are the choke points – apply resources
Subcontractor/Suppliers
Cost & schedule
On track technically

6. Typical Phase Gates for MGMT
System Requirements Review
System Functional/Design Review
Preliminary Design Review
Critical Design Review
Test Readiness Review
Production Readiness Review
Shipping Readiness Review

7. PMTE People Methods Tools Environment
Right knowledge, skills, abilities? = Training Plan
Right people at the right time? = Staffing Plan
Key Stakeholders? = Stakeholder Involvement Plan & Artifacts
Methods
Proven Processes? = Process Tailoring & Support, Stakeholders
Key Events, Activities, Criteria? = IMP, IMS, SEMP/SEP
Tools
Company standard? = Templates, Enablers, Checklists
Standards? = Project/Engineering Notebook, Reference Architectures
Environment
Leadership buy-in & support? = Senior Management Reviews
Metrics? = Earned Value Measurement, Measurement Analysis,
Decision Making? = Trade offs, Technical Performance Measures, Risk & Opportunity Management

8. Baselines Main thrust of SE is orderly synthesis
Setting & Maintaining BASELINES
Requirements baseline
Functional baseline
Allocated baseline
Production baseline
Controlled changes with full understanding of change impact –
Change Management (CM)
Data Management (DM)
Configuration Control Board (CCB)

11. Concept Review Checklist
CONOPS
Conditions of operation
Conditions of maintenance & support
Mission analysis & Scenarios (Normal, Abnormal, Emergency, Catastrophic)
Extracted functional analysis and interface analysis
System Need
User performance, design constraint, environment, and interface requirements
Mission event timeline, phases, system states/modes
System requirements (performance, environmental, interface, design constraint)
Concept Architecture
people, facilities, hardware, software, data, support equipment & tools, technical data, training, logistics concepts

12. Example in Text book Blanchard, p. 96, Figure 3.27 Others
DAU SE Handbook
Domain specific
Company specific (within its process)
Have at least a “general” set of topics
Checklists are “don’t forgets” – the gator is watching!

13. Example from MIL-STD-1521B
Mission/Requirements Analysis
Functional Flow Analysis
Preliminary Requirements Allocation
System/Cost Effectiveness Analysis
Trade Studies
Logistics Support Analysis
Specialty Discipline Studies
System Interface Studies
System Performance Specification
Program Risk/Opportunity Analysis
Integrated Test Planning
Producibility Analysis
Technical Performance Measures
Data Management Plans
Configuration Management Plans
System Safety Program Plan (SSPP)
Human Factors Analyses
Value Engineering Studies
Life Cycle Cost Analysis/CAIV
Prelim Manufacturing Plans
Manpower Requirements & Personnel Analysis
Milestone Schedule
IMP/IMS
Supply Chain Management & supplier selections
Specific actions/plan to get to next gate: SRR/SFR/SDR

14. See “Class Projects 1-5.doc” file
Class Project Briefs
5 topics for each briefing
Uses information built up through home work & readings
5 minutes to brief the 5 topics
WRITTEN material is GRADED
VERBAL material is graded
CLASSMATES get to ask questions
See “Class Projects 1-5.doc” file

15. Suggestions Use the assignment description as a checklist
Ensure you meet the threshold criteria for your briefing (5 topics) – See handout with topics to be covered at each review
Use figures, charts, graphs
Avoid charts with LONG text
Bullets are better, faster, cheaper

16. Review from RESOURCES Download the file “10 Golden Questions”.
Use it to help identify the information needed for your selected system.
Make sure you can state the “purpose” for the selected system, its mission system and its support system.
Make sure you can draw a context diagram for your selected system.
Sketch a CONOPS for your system (mission)
Identify examples of each of the four types of requirements.
