project overview
 Vetworking will be developed using the eXtreme programming
methodology in which Norman has (1) taught as a graduate
teaching assistant (software project laboratory), (2) followed the
process as a software engineer at Nortel Networks, (3) followed the
process as a software engineer at Raytheon, and (4) as a DOD Air
Force proposal reviewer subject matter expert (SME) at the MITRE
Corporation.
 This is a de facto industry standard process with tailoring to specific
domains. Norman will use the methodology to generate sufficient
artifacts for the future of the project, which is implementation using
specific programming language, middleware, in a specific
platform.

design artifacts
 The scope of this project is to create design artifacts for the purpose to
hand off to a programming team. The design artifacts that will be
produced are:
 User Stories (a prose description of the project)
 Class Diagrams (data structures for object-oriented implementation)
 Sequence Diagrams (description of interaction activities between system
objects)
 Option: State Diagrams if artificial intelligence or machine intelligence
constructs are deemed of value.
 In commercial industry, the above software artifacts will be sufficient for
programmers to develop an initial prototype to begin the
programming-level activities of the Agile system development
methodology.

agile methodology
In 2001, 12 Agile software development principles were developed in Utah,
think in context of Acquisition PMO (users), Contractor Managers, and
Contractor Developers:
1. Availability of software to government for in-process evaluation
2. Flexibility in editing requirements
3. Software delivery frequency
4. Communication approaches between government and contractor
5. Quality of software developers and their development environment
6. Communication approach amongst software developers
7. Clear articulation of software development progress
8. Sustainability of software development tempo
9. Awareness and guidance with regard to technical excellence
10. Simplicity of development process
11. Software Developers' understanding of government requirements
12. Software development team self-evaluation approach

Program Performance Metrics
While initially provided requirements are Kite-Level business requirements pertaining to technical activities, system engineering thinking indicates a need to frame the project for the purpose of meeting possible unspoken longer-term program needs.
Recommend considering the possibility of engaging with the Northern Virginia Technology Council (NVTC) to consider program accountability and performance metrics.
Suggested measurements for consideration:
•Extended veteran employment status data
•Financial and managerial accountability measurement
•Feedback to role performance
•Plan to improve role performance
•Committee for business process and activity review and improvement

Roles
Veteran: The focus of this program. The goal of the program is to place
each veteran into permanent work.
Career Coach/Facilitator: Qualified subject matter expert whom is
effective in placing veteran-type clients into permanent work.
Mentor: A veteran’s personal confidant who assist veteran in adjusting to
civilian life.
Donor: People who gives money to NVTC to administer for the purpose of
help veteran to obtain permanent work.
Facility Host: A facility manager that is able to provide a venue to host
Boot Camp activities.
Caterer: People who provide food and refreshment during Boot Camp.
NVTC Administrator: Program management office that oversees and
responsible to effectively provide veteran with permanent work.

High Level User Story
 VETworking is a program operated by the Northern Virginia
Technology Council (NVTC) designed to help veterans apply their
skills in the workforce and be exposed to job opportunities. This
computational solution will support continual administration of this
program to coordinate all participants, majority volunteers, for the
propose of matching veterans to permanent work.

Business Process Analysis for User Stories

User Story #1
 Name: Provide portals for all users.
 Each of the seven roles (Veteran, Mentor, Donor, Career
Coach/Facilitator, Facilities Host, Caterer, and NVTC Administrator)
will be able to log into the VETworking system from various
computing devices for the first time to establish an account and re-
login to the system to work their role’s activities.

User Story #2
 Name: Entering role-specific information.
 Each of the six roles (Veteran, Mentor, Donor, Career Coach,
Facilities Host, and NVTC Administrator) will be able to enter role-
specific information into the system. A minimum set of information is
sufficient to establish an account to prevent repeated entering of
same information. The system will prompt and help user to
complete unfilled information or required role-specific activities.

User Story #3
 Name: Donor functions
 A donor visits the website and is directed to a link which enable the
donor to give money to NVTC.

User Story #4
 Name: Facilities Hosts Information
 A Facilities Host (FH) logs onto the system and sees a display of Boot
Camp dates. The FH selects date(s) to indicate the availability of
the facility to host a Boot Camp. FH then continues to fill out
tailoring information such as Need a Caterer (Y/N), Maximum
Participants, Address, Preferred Contact, etc.) If FH has already
filled out such information on previous visit, this question sheet will
be pre-filled with the stored information.

User Story #5
 Name: Facilitators functions
 A Facilitator, aka qualified Career Coach, logs on to the system and
enters choices for the Boot Camp date(s). A visual display will show
the status of chosen dates and the next steps of the procedure.
When a Boot Camp pre-conditions are met, notice will be sent to all
participants to confirm the event.

User Story #6
 Name: Caterers functions
 A Caterer logs on to the system and enters choices for the Boot
Camp date(s) for which to provide services. The Caterer can view
number of participants, location, and other information to make a
decision. A visual display will show the status of chosen dates and
the next steps of the procedure. When a Boot Camp pre-conditions
are met, notice will be sent to all participants to confirm the event.

User Story #7
 Name: Event Business Process
 The system checks the pre-conditions of each Boot Camp. After the
venue has been selected, a facilitator has been identified, and
other pre-conditions satisfied, the system will notify all participant of
the successful arrangement of the date and move on to the pre-
event preparation activities. If time is within 24 hours of the event
date and event pre-conditions are still not satisfied, then a message
will be send to participants and they are prompted to register for
another event.

User Story #8
 Name: Veteran and Mentor Match
 The system will generate veteran and mentor matching report
based on the likelihood of long-term (greater than 12 months) total
benefit estimate for each veteran. The report will be provided to
the NVTC administrator. The veteran report will have that veteran
and also a top-five matching mentors list for that veteran. There will
be reason(s) and an action list for veterans who has no matches.
Similarly, the mentor report will have that mentor and a top-five
matching veterans for that mentor. There will be reason(s) and an
action list for mentors who has no matches. Each action item is
added to a to-do list which is tracked. The NVTC administrator is
responsible for the management of follow-up actions after
receiving the reports.

User Story #9
 Name: Event Selection
 After an initial meeting and if the veteran and mentor decided to
continue their relationship to work together to match the veteran a
permanent work, the veteran and the mentor will register for a Boot
Camp event. The mentor and veteran will complete all pre-event
activities, including creating an on-line plan to find permanent
work.

User Story #10
 Name: Event Rules
 The users of the system will receive alternative and other options
during all activities including scheduling of event dates for each
participants, matching mentors to veterans, and useful report and
suggestions that can improve program performance metrics. This
automation optimization capability shall be available for review
and for tailoring by the NVTC administrator.

User Story #11
 Name: Administrator Functions
 The system has full range of control regarding information disclosure
of all participants. The system administrator is responsible for setting
the flexible privacy options. An designated NVTC administrator will
work with a designated MITRE system administrator to configure all
system functions for the purpose of conformance to U. S. Code and
for the purpose of optimizing all resources for the purpose of placing
veterans into permanent work.
