HIFI is a large project
• Many people are attracted in the development days• Some as rooftile, some temporarily• The number of people in Groningen is doubled, but is it enough?
• The atmosphere is vibrant, but also tense from time to time• Problems are solved, but...• Schedule is very tight

Consortium meeting juli 2000

Villa Tuscolana Frascati
WBS/HRS selection
• There is not enough money for two spectrometers• ESA also insists on simplification
• What to do? Descoping? That means a review
• One of the national leads explodes during the consortium meeting (my first)
• In the end we fly both HRS & WBS and the peace is restored!
• How come?

Why remained the consortium intact?
• We share the same goal – getting the instrument done• We experience the peer pressure – we don´t want to be less
than the others• We do something nobody has ever done before – that is difficult
and exciting
• We avoid that others loose face• In reviews we express the problems we find• We share knowledge• We try to have an open development culture
• Consortium meetings are always well attended – Also now the ICC co-locations have an attendance of over 30 people

In the end it is a real struggle – but it works

Steps towards launch
• Integration on the satellite is slow• We go from review to review and finally we are accepted in the
Instrument Flight Acceptance Review• Operations also has simulations and review after review – finally
we have the Commisioning Phase Review
• We can start preparing for launch – we have the SRON lottery• We start booking, but face delay after delay. In the end we fly,
but are not sure if we have accomodation even if we enter French Guyana (and my telephone also doesn´ t work over there)
