Self Training

the ECOS training courses are designed to advise users how to create cost proposals in ECOS, including building the product tree (PT) and the work breakdown structure (WBS), issuing ITTs to subcontractors and integrating Tender Answers, as well as analysing the reports produced by ECOS. 

Please contact the Help Desk for information on the next course. All courses take place at ESTEC Noordwijk, Netherlands. 

Applications for this course are required to be submitted to the ECOS Help Desk, by fax or e-mail, at your earliest convenience. The maximum number of participants per company is normally restricted to two.

Self-Training Manual allows anyone having to submit ECOS files associated to a financial proposal to get acquainted with the application software within an estimated time of a normal working day.

For practical reasons, it is recommended to initiate ECOS training via the self-training document at the soonest to work efficiently and with confidence. Further training and associated advices delivered during the training sessions at ESTEC may complement this initial training.

The Self-Training now exists in two versions:

  • The Self-Training Manual including all ECOS 5 features (count 8 hours for completing it)
