Report
Are you a Software Engineer
OR
Is it just your Designation ?
Y. Raghu Reddy
Associate Professor
Software Engineering Research Center
IIIT Hyderabad
What are we lacking?
• India graduates nearly half million engineers every year
• Information Technology
• Information Science and Engineering
• Computer Science and Engineering
• Computer Engineering
• Other computing variants…
• Substantial numbers enter the IT workforce
• Common complaints – Not Employable
• Lack Essential skills (technical & soft)
What do these have in common?
CODE!!!
Huge complex systems!
(Quality) products ?
0.5 SLOC/min/resource * 60 min/hr * 40
hrs/wk = 1,200 SLOC/wk/resource
1,200 SLOC/wk/resource * 50 wks/year =
60,000 SLOC/year/resource
2 * 10^6 SLOC / 0.6 * 10^5
SLOC/yr/resource = ~34 Resources for the
year
Approaches to Software Quality?
• Focus on Process
• Focus on Product
• Focus on People
 Need for introducing Software Engineering as a
degree program
 Need for licensing current industry professionals
Software Engineering as a discipline
• Software Engineering IS NOT Computer Science
• Software Engineering is an ENGINEERING discipline that
specializes in the design of software
• Considering it a discipline will help in aligning it with
traditional engineering disciplines
• There are 5 things a software engineer should be good at:
Programming, Design, Process, Communication & Team
work
SE programs at undergrad level?
• The distinction between CS, SE, IT was recognized by
ACM and IEEE in late 1990s, Early 2000s
• SwECC was formed
• Led to creation on specific Software Engineering programs
• Accreditation bodies now accredit software engineering
programs
• ABET (U.S and outside)
• CSAC (Canada)
• etc.
Is it possible?
• Do we have a core body of Knowledge?
• Software Engineering Body of Knowledge (SWEBOK) 2013
• Mechanisms for assessment
• Software Engineering Competency Model (SWECOM)
• ABET accreditation (U.S body) – there are equivalent versions in
Australia, Canada, U.K.
• Nearly 22 programs in U.S are ABET accredited – student who graduate
consider themselves as “Software Engineers”
• Have seen the distinct difference
• Colorado State University (Computer Science program)
• Rochester Institute of Technology (Software Engineering program)
• IIIT Hyderabad (Computer Science and Engineering program)
SE programs
• Do CSE programs get accredited?
- By who (NBA in India, there are two by ABET but by CSA bodies)
- Do we have a body that accredits Software Engineering programs?
Simpler question: How many accredited Software
Engineering programs do we have?
“Zero”
What can we do?
• Can we change?
• Will we change?
• To start let’s recognize that there is more to software engineering
than just the designation.
• What about all those ENGINEERS who are graduating every year?
• Do we want them to be SOFTWARE ENGINEERS?
• Do we want them to be LICENSED SOFTWARE ENGINEERS?
HELLO
Are you
Licensed?
Licensing Software Engineers
• Civil Engineers, Doctors, Lawyers are licensed (Provides a
form of assurance)
• We are familiar with Vendor Certification, product certification,
process conformance (Audit).
• So why not people?
• Can we define “engineering” by what they “practice” rather
than their “title”
• A certification program to authenticate practitioners’
competency
Professional Engineers (PE)
Current Status
• CIPS Information Systems Professional (I.S.P.),
• IEEE Software Engineering Certification (CSDP or CSDA)
• Professional Software Engineer
• The Seoul Accord, Dublin Accord, Washington Accord,
Sydney accord are international accreditation agreement
for academic degrees.
What does it take to get licensed?
• Holding a bachelor's degree in software engineering from an
ABET-accredited program.
• Passing the Fundamentals of Engineering (FE) exam.
• Having applicable work experience (typically, at least four
years) under the supervision of a licensed professional
engineer (PE).
• Passing the Principles and Practices of Software Engineering
(P&P) exam
Principles of Good Design
• Divide and Conquer
• Increase cohesion (keep related stuff together)
• Decrease coupling (minimize dependencies between modules)
• Increase the level of abstraction wherever possible
• When two modules interact, create abstract interfaces so that
modules don’t have to know specific low-level details about other
modules
• Design for Quality of service (Testability, Flexibility, Modifiability, etc.)
• Design by Contract
Going forward
• There have been, will be arguments for & against licensing
software engineers…
• Canadian provinces, U.S (about 40 states)
• software engineers working on systems that affect the health, safety,
and welfare of the public as well as those offering their services
directly to the public
• With the emergence of Cyber Physical systems, there is potential for
this to expand
Thank you !!!
