FAQ
Before you ask.
Can the material be tailored to our facility?
Yes. Every programme is adapted to the client's plant, equipment and participants, which is why no fixed module list is published.
How long is a programme?
From a one-day technical session to a three-day intensive, depending on the topic and what your team needs.
Do you train online or on site?
Both. In-house corporate sessions, customised company programmes and online delivery are all available; classroom or public sessions run when there is demand.
Which language is the training delivered in?
English or Bahasa Indonesia. I am a native Indonesian speaker and was educated in English in Qatar.
Why are fees not listed?
They depend on the topic, format and group size, so each request is quoted individually.
