A Seminar/Workshop consists of a collection of individual topics, as can be found below.
Choose your own seminar by combining topics of your interest:
- Individual topics can be found in the table below.
- If you desire a seminar with a topic not found in the table below, please contact me.
A workshop for your company typically consists of the points below:
- In-depth analysis of your technical challenge.
- A seminar(or collection of), concerning necessary knowledge to understand your technical challenge.
- A solution proposal (by round-table discussion).
Typically, discussion during and after the presentation of a topic usually extends the duration considerably.
