2 Recent Purdue SE discussion / thinking 3 Purdue Activities Related to Systems Engineering
System of Systems signature area
Trans-disciplinary research initiative originated by AAE faculty member
College-level involves faculty in several schools
AAE Aerospace Systems area
Research and curriculum for design development operation of aerospace systems (aircraft spacecraft etc.)
Within AAE involves plans of study shared research interests PhD qualifying examination
Systems Engineering education
Educational support to SoS research
Address external stakeholder needs for graduate education in SE
Could be college-level currently AAE-led support offered from ProEd
AAE Aerospace Systems area System of Systems signature area Systems Engineering education 4 Stakeholder / Customer Push for SE
Industry and government employers looking for systems engineers
Aerospace / defense organizations
Raytheon Lockheed Martin Boeing General Motors BAE Systems Rolls-Royce GE Aircraft Engines NASA USAF
Other engineering / product development companies
Cummins General Motors International Truck
Student interest developing around new course offerings
Purdue Alumni at companies are earning graduate SE degrees from other universities
Crossroads of America (IN / IL) chapter of INCOSE actively engaging Purdue have twice hosted mini-conference on campus
Involvement with Lean Aerospace Initiative highlights need for systems engineering
Student interest in systems engineering topics and in academic programs linked to SoS signature area
5 Plans for SE Academics at Purdue
Interactions to gain best practices and to see potential models with
Lockheed Martin Boeing Cummins NASA
Air Force Systems Engineering Center of Excellence
AERO (Aerospace Education Research Operations) Institute in Palmdale CA
Center of Excellence in Systems Engineering at Indiana-Purdue Ft. Wayne
Purdue Engineering Professional Education (ProEd)
Offers graduate courses non-thesis MSE degrees to distance-learning students
Fall 2007 offered GRAD 597N Introduction to Systems Engineering
Instructor Dr. Dan Surber Principal Engineer of Systems Engineering and Systems Safety Engineering Division at Raytheon Technical Services Indianapolis IN
Taught using studio facility at IUPUI in Indianapolis
Available only to distance-learning students for Fall 07 intend to have available for on-campus West Lafayette students Fall 09
New Engineering Management and Leadership MSE degree specialization
Plans of study will contain 9 credits of systems engineering topics
Common SE courses to support ProEd MSE specialization and on-campus area of concentration
6 Options for SE Academics at Purdue
Three major options
Area of concentration
Students earn MS degree from traditional engineering program
Post-baccalaureate course work fewer credits than MS degree
MS degree in Systems Engineering
Non-thesis option likely thesis option possible
Prevailing attitudes favor Graduate Area of Concentration in SE
Most Purdue on-campus students have little previous work experience
Often cited as necessary prerequisite for graduate degree in Systems Engineering
Re-emphasized in discussions with Mike Griffin NASA Administrator
Comparative ease of implementation
No new school or department
No (or few) new additional faculty
Several existing Areas of Concentration to provide template
7 Potential Graduate Area of Concentration
Students earn graduate degree from existing school
For example MS AAE MS CE MS ME etc.
Total of 30 credits (all course work if non-thesis option 21 credits course work with thesis option)
Systems Engineering area of concentration appears on transcript
Students take three to four SE courses (nine to 12 credits) from an approved list
Choose from a core list covering SE topics and a related list with discipline-specific topics
Need to leverage GRAD 597N Introduction to Systems Engineering course as a core course
Several precedents exist for this
Software Engineering - cooperation between Computer Science and Engineering (across Colleges) one of the most visible
8 Potential Certificate Program
Post-graduate studies resulting in an awarded certificate
12 or 15 credits (four or five courses) in Systems Engineering
Courses from same list of courses that could be used in area of concentration (at graduate school level not short courses)
Precedents exist for this
Digital Signal Processing from EE as an example
Quality Engineering program under development as interdisciplinary
Purdue Engineering Professional Education (ProEd) helping to coordinate new certificates
Enables off-campus students to pursue advanced study
A lower-commitment than direct entry in MS program
9 Graduate Degree in Systems Engineering
Would require an entire SE curriculum
30 course credits for MS non-thesis 21 for MS thesis option
Likely need several new courses
Faculty needed to serve as advisory committee chairs and members
Thesis topics in SE maybe more difficult to define
Should include some sort of SE practice / case study / similar as formal part of program
Somewhat more challenging to implement
New faculty likely needed
New program or department needed
10 SE-related Courses on Campus
Many engineering faculty have teaching and research interests aligned with systems engineering
Systems engineering-related courses are currently available on campus
Predominately graduate (dual 500) level courses
Focus is usually discipline-specific (e.g. aerospace systems civil engineering systems)

16 Next Steps for Purdue SE
Purdue participants to move forward with formalizing and gaining approval for Systems Engineering area of concentration
Formalize SE curriculum/ academic advisory council
Analog to school industrial advisory council
Industry and government SE experts to help craft programs provide continuous improvement
Leverage ProEds Introduction to Systems Engineering course
Serve as core course independent of specific disciplines
Facilitate on-campus student enrollment
Identify opportunities for case study and SE practice as part of academic studies
Requires input and collaboration from industry / government advisory council and other partners
17 Continue cooperation to better serve Ph.D. program development
Internally consider Branding what level of recognition is needed now (vs. what may happen more naturally with time)
what may quicken that impact (eg. rankings funding success of junior faculty hires continued communication/support between and within consider ES/SE in ENGR 2020 education initiatives)
Opportunities to share experience with new AAE home- building developed for cross-disciplinary engineering and research Neil Armstrong Hall of Engineering
Continue hiring/recruiting faculty across Engineering Schools (depts). Including AAE Civil Industrial Eng.
SoS has hired 2 faculty over the last 3 years interviewing now - will hire this 1 year 2 in coming 2-4 years.
IE alone has 9 faculty positions remaining (hired 3 in the past year interviewed 10 this semester will likely hire 3 this year)
Head Search - Industrial Engineering - position announcement
18 ES/SE Program Development Challenges
At M.S. level
there are obvious new program opportunities to meet external demand
however junior faculty time spent in new course prep for grad level courses that primarily have non-research track students can be (justifiably) questioned by senior faculty concerned about long term School/College interests
At Ph.D. level
New faculty hires require awareness among existing faculty about potential impact of multi-disciplinary trans-disciplinary and/or cross-disciplinary research
A blending of research cultures (across disciplines) and faculty generations is occurring
consideration of breadth vs. depth can be supported by faculty cooperation yet junior faculty may be evaluated somewhat by their ability to develop their research portfolios more independently
continual balancing of preconceived notions of need within the College with perspectives on excellence eg. know it when you see it.
