1. What is the difference between a Life Cycle Model and and Development Life Cycle
Model? (1pt)
Ans. Life Cycle Model includes all the phases from inception to decommission (or
retirement) of the system, while Development Life Cycle Model includes only the
‘Development’ phases. That is, Development Life Cycle Model is a part of the Life
Cycle Model. The Development Life Cycle Model generally excludes Manufacturing,
Deployment, Operations, Maintenance, and Retirement phases.
Life cycle model is collection of all phases from conception to close out of the
project. It define what work will be performed at each phase, what deliverables will
be produced and when, who is involved at each phase, and how management will
control and approve each work produced in each phase.
The Development Life Cycle has a portion of the life cycle dealing with the
development. This is used as frame work for developing information systems and
software development, because it include requirement, design, implementation/
coding/ unit testing, integration testing/verification. Unlike the life cycle model, the
development life cycle spend a large portion of the project effort attempting to clarify
the requirements of the project and developing.
2. List the activities and milestones associated with the DoD System Development and
Demonstration Phase Life Cycle Model. What kind of model is it? (1pt)
The activities and milestones associated with the DoD System Development and
Demonstration Phase Life Cycle Model are sequentially –
Milestone: B
“An affordable increment of militarily-useful capability has been
identified”
“The Technology for the increment has been demonstrated in a relevant
environment” (i.e., TRL 6)
“A system can be developed for production within a short time frame
(normally less than 5 years)”
Refine System Performance Spec & Environmental Constraints
* System Requirements Review (SRR)
Develop System Functional Specs & System Verification Plan
* System Functional Review (SFR)
Develop CI Functional (Design to) Specs & CI Verification Plan
* Preliminary Design Review (PDR)
Develop Product Documentation and Inspection Plan
* Critical Design Review (CDR)
Design Readiness Review (DRR) Milestone
Fabricate/Assemble/Code
CI Verification Development Test & Evaluation (DT&E)
Verify System Performance: Integrated DT&E & Live Fire Test and Evaluation
(LFT&E)
Test Readiness Review (TRR)
Verify System Functionality: System DT&E & LFT&E, & Operational
Assessment (OA)
Demonstrate System: Combined DT&EO/OT&E/LFT&E
* System Verification Review (SVR)
* Production Readiness Review (PRR)
* Functional Configuration Audit (FCA)
Milestone: C
“An affordable increment of militarily-useful capability has been
identified”
“The Technology for the increment has been demonstrated in a relevant
environment” (i.e., TRL 6)
“A system can be developed for production within a short time frame
(normally less than 5 years)”
DoD System Development and Demonstration Phase is a “V” LCM.
3. Explain how the “V” model is essentially a classic waterfall model? Why is it drawn
as a “V”? (1pt)
The V model is essentially the classic waterfall model because the sequential of
processes, each process must be completed before the next phase can begin. The V
model and classic waterfall model all include the requirement, design and analysis,
implementation, testing, and maintenance.
The V model is drawn as V shape because at each phase, it maps to the corresponding
test levels. For example, the requirement analyses would correspond to the acceptance of
design at the. The high level design correspond to system testing, integration correspond
to system integration testing and so on. The bottom or the V represent the critical design
review that would decide the development.
4. Go to the DAU Systems Engineering web site
<http://www.acq.osd.mil/ds/se/publications.htm>. Download (and skim) a copy of the
“Systems Engineering Plan (SEP) Preparation Guide”.
5. Download a copy of my recommended SEP Annotated Outline from Blackboard &
read it.
6. 1.Develop an annotated draft Systems Engineering Plan for your Project (IN YOUR
OWN WORDS, DO NOT COPY MINE) (1 pt)
7. Develop drafts for each of the following Sections (5 pts):
1.1.2 Program Description
1.2 Program Technical Status (Address DOD Acquisition Life Cycle)
1.3 Approach for SEP Updates
2.3.1.1 Technical Development Process (Address Development Life Cycle and
Systems Engineering Process)
2.3.1.2.1 Technical Planning (Include a WBS)
2.4.2 Technical Reviews
8.1 Take the Myers-Briggs Test
8.2 Develop a Team Personality Profile (E/I, S/N, T/F, J/P Result/Score for each team
member)
Mollick A. Arefin: (I, N, T, J) = (33, 75, 25, 44)
Personality type:


