Outsourcing perspective in WECs
Knowledge - good Culture – more less similar to Europe
countries culture Time zone – 1-2 hour for Europe; 6
hours for USA Salary – depends of the region,
between 400-1000, sometime senior developer much more (1500 or more)

What is missing? Theory versus practice Theoretical knowledge demonstrated
on examples Problems:
Exercises and labs very simple and time limited
Projects realized by one or two students Students – not very interested in
imaginary problems

Questions Year of your graduation Years (months) of your working experience (1-10) What knowledge did you need right at the beginning of your career
that you have not get during your studies? (Java, C#, Debugging…) Do you think that programming language knowledge attained
during your studies were enough? If not, quote knowledge that you think should be included in regular studies. (Web services, UML, JavaScript, …)
Do you find Software Engineering knowledge from the faculty usable in practice? (Yes, but not enough)
Would you change something and what? (Real projects, bigger teams…) What software-developing methods are used in your company:
Structured methods Data-oriented methods Object-oriented methods Formal methods (deals with mathematically based software
engineering methods) Prototype methods (involves software prototyping)

Recommendations
For University For companies For students
![Page 20: Software engineering and outsourcing Dragan Jankovic Tatjana Stankovic Faculty of Electronic Engineering University of Nis, Serbia 8th Workshop "Software](https://reader036.vdocument.in/reader036/viewer/2022062300/56649da25503460f94a8f5e2/html5/thumbnails/20.jpg)
For University More practical exercises More practical labs Modification of SE curricula Practical works in groups Project group size more than 5 students Assistants with practical experiences Projects in companies Story from real life
![Page 21: Software engineering and outsourcing Dragan Jankovic Tatjana Stankovic Faculty of Electronic Engineering University of Nis, Serbia 8th Workshop "Software](https://reader036.vdocument.in/reader036/viewer/2022062300/56649da25503460f94a8f5e2/html5/thumbnails/21.jpg)
For companies
It is not real to expect “yang ready full developer”
Learning period Demonstration with courses and
tutors To offer including of students in real
projects
![Page 22: Software engineering and outsourcing Dragan Jankovic Tatjana Stankovic Faculty of Electronic Engineering University of Nis, Serbia 8th Workshop "Software](https://reader036.vdocument.in/reader036/viewer/2022062300/56649da25503460f94a8f5e2/html5/thumbnails/22.jpg)
For students
Force cooperation with assistants and professors
Force interactive lectures
![Page 23: Software engineering and outsourcing Dragan Jankovic Tatjana Stankovic Faculty of Electronic Engineering University of Nis, Serbia 8th Workshop "Software](https://reader036.vdocument.in/reader036/viewer/2022062300/56649da25503460f94a8f5e2/html5/thumbnails/23.jpg)
Conclusion
Software engineering in our faculty gives very good experts, but there is place for improving
Experts as guest-lecturers should definitely be one of the improvements
The idea of the exception of investigation team at the university should be considered?
