Supplier selection, negotiation, materials management, delivery reliability. Technical understanding separates real negotiation from simple price pressure.
Industrial engineering while you keep working
The subject has a reputation for offering too little of both worlds. Sometimes that is true, sometimes it is exactly the right degree. What the difference hangs on is set out here, with admission, credit transfer and workload.
Where it sits
What industrial engineering is, and what it is not
A subject you can only understand through its two neighbours.
Industrial engineering sits at the interface between technology and business administration. The core consists of technical foundations such as mathematics, physics, materials and manufacturing, alongside cost accounting, procurement, production management, logistics, controlling and commercial law. Most programmes carry a specialisation, usually mechanical engineering, electrical engineering, construction or logistics, and that choice shapes your profile more than the degree title.
- Mechanical engineering goes deeper technically. If you want to design, dimension and calculate, that is where you belong.
- Business administration goes deeper commercially, from accounting through finance to marketing, and leaves out the technology.
- Business informatics solves the same translation problem for the IT side. If you mediate between a department and software development, that is usually the subject you want.
And now the criticism you find in every forum: that you learn too little of both. The objection is not made up. A bachelor's degree here has neither the calculation depth of a mechanical engineering degree nor the commercial depth of a business degree, and within one programme that cannot be fitted in. What matters is what the degree builds on.
If you come from a technical trade, know the shop floor and want to grow into the commercial side, you bring the depth from practice and add to it in your studies. That profile is in demand precisely because it can translate between development, manufacturing and purchasing. If you enter with neither background and pick no specialisation, you end up exactly where the criticism points. The consequence is simple: choose your specialisation early and make your own work experience the anchor.
Admission
Also without A-levels, from two directions
No other engineering subject accepts this many different backgrounds.
Admission here works from both sides. From the technical side, a state-certified technician and an industrial master craftsman open general university access in most German states. From the commercial side, a certified business specialist and a certified business administrator do the same. Without such a qualification the route runs through subject-linked access: an apprenticeship plus several years of relevant practice, depending on the state with a counselling interview, an aptitude test or a trial semester. Both technical and commercial occupations can count as relevant, which widens the circle compared to the pure engineering subjects.
The three routes in detail are set out under studying without A-levels. If you are planning the degree as a move into a different field, also read career change through a degree, because the timing of the move often matters more than the qualification.
The share of mathematics is lower than in mechanical engineering, but it is there. Statistics, investment appraisal and the technical foundation modules assume confident arithmetic. If your school mathematics is a long way back, take the preparatory course.
Credit transfer
The subject with two sources of credit
Technical and commercial prior learning both pay in here.
Industrial engineering is one of the few subjects where two different qualifications feed into the same degree. A technician or master craftsman matches the technical modules, a business specialist or administrator the commercial ones. Anyone bringing both, which happens in industry more often than you would think, comes close to the usual ceiling of 50 percent of a programme's ECTS.
What that means in time is a simple calculation. Take a bachelor's programme worth 180 ECTS. If 60 are credited, 120 remain. At 10 ECTS per semester, which is realistic alongside a full-time job, that is six years instead of nine. You have changed nothing about your daily routine and saved three years.
The order matters. Clarify the credit first, then choose the university. With identical prior learning the differences between providers are considerable, and the business specialist qualification in particular is assessed very differently from place to place. How the procedure works is explained under credit transfer and on my page on credit for work experience. Which universities exist can be compared with sources on Hochschulnavigator.
Workload
Time and cost, realistically
Less lab work than in the pure engineering subjects, more reading instead.
| ECTS per semester | Hours per week | In daily life | Bachelor takes |
|---|---|---|---|
| 5 | around 7 to 8 | one module, useful as a test before full enrolment | 18 years, only sensible as an entry semester |
| 10 | around 15 | two evenings plus one weekend day, workable with travel | 9 years, 6 with credit transfer |
| 15 | around 22 | tight as soon as project peaks hit at work | 6 years, 4 with credit transfer |
| 20 | around 30 | effectively a second part-time job | 4.5 years |
Calculated at 30 hours per ECTS and around 20 active weeks per semester. How to work out your own figure is explained under ECTS per semester.
One practical advantage over electrical engineering and civil engineering: the lab share is smaller and many modules can be worked through entirely off site. On-site dates remain for exams and project work, but the number of compulsory appointments is smaller. If you travel a lot, you are more likely to find a programme here that fits.
On cost, part-time bachelor's programmes usually sit in the range of a few hundred euros per month. What decides is not the monthly rate but the total at a realistic pace, and that falls above all through credit transfer, see what distance learning costs. Because this profile is directly usable in purchasing, costing and project management, the business case is easy to make to an employer, see getting your employer to pay.
Afterwards
Where the degree leads
Three directions that differ clearly in daily work and demands.
Costing and controlling
Quotation costing, cost accounting, investment decisions, post-calculation. Desk-based, numbers driven, often the entry into a staff function.
Projects and processes
Project management, process optimisation, production planning, quality. Much coordination between departments that otherwise talk past each other.
An honest word on pay: the degree alone does not change it, the changed position does. Anyone doing the same job after the degree typically earns the same. More on this under salary after your degree.
And one limit worth knowing: the degree does not automatically entitle you to use the protected professional title of engineer. That title is governed by the engineering acts of the individual German states and requires a technical or scientific degree with a corresponding share of engineering content. With programmes carrying a high business share that is not guaranteed, and there are court decisions on the point. If the title matters to you, have the programme checked by the responsible authority in your state before you enrol. For most roles in purchasing, controlling and project management the title plays no part.
Frequent questions
Industrial engineering by distance learning
The questions that come up in almost every initial consultation.
Is the criticism true that you learn too little of both?
It is not made up. An industrial engineer has neither the calculation depth of a mechanical engineer nor the commercial depth of a business graduate. What matters is what the degree builds on. If you come from a technical trade and grow into the commercial side, practice and degree combine into a clear profile. If you enter with neither, the criticism tends to fit.
Can I study industrial engineering without A-levels?
As a rule, yes, and unusually many prior qualifications fit here. A technician, an industrial master craftsman, a certified business specialist or a certified business administrator opens general university access in most German states. Without such a qualification the route runs via an apprenticeship plus several years of relevant practice, and both technical and commercial occupations can count as relevant.
May I call myself an engineer after graduating?
Not automatically. The professional title of engineer is protected by the engineering acts of the individual German states and requires a technical or scientific degree with a corresponding share of engineering content. With programmes carrying a high business share that is not guaranteed. If the title matters to you, have the specific programme checked by the responsible authority in your state before you enrol.
How much of my prior qualification counts towards the degree?
Often more than in other subjects, because two sides can be credited. A technician or master craftsman matches the technical modules, a business specialist or business administrator the commercial ones. How much it is in practice differs considerably between universities. For learning acquired outside higher education, an upper limit of 50 percent of a programme's ECTS usually applies.
What is the difference to a business administration degree?
Business administration goes deeper commercially, from accounting through finance to marketing, and assumes no technical background. Industrial engineering trades part of that for technical foundations and production-related subjects. If you want to mediate between development, manufacturing and purchasing in technical industries, it positions you better than business administration alone.
