2. Space project phasing: data levels and data use

Expected learning outcome for this Part Knowledge of the ESA phasing for both project and data and its evolution
Level of advancement for this part Beginner
Approximate time to complete this Part 15 min.

Originally, a space experiment  was the adaptation to space of a technique already tested on the ground, on balloons or on airplanes. Space was seen essentially as adaptation to space conditions and space platforms. The details of the process were already present in the proposal and after proposal acceptance, tests were performed first on a table model and then on a prototype.  The integration of the experiments in an industrial chain changed this process and necessitated much more uniformity and formality.  Data phasing followed the same paths so that clear definitions could be given for each flux of distributed data.

Expected learning outcome    The student will know at proposal level which steps will be necessary in order to finally fly the mission; students will also learn the practice on data classification and the for distribution to users or preservation.
Level of advancement Graduate level with basic knowledge of digital data representation.
Elements in this Part Phasing and data levels
Phasing has already been the object of several tutorials; one example is the ‘Space Project Management Chris Cully 8 April 2008 chris@irfu.se (Based on 2007 lectures by Petrus Hyvönen)’ presented at the University of Uppsala (http://www.space.irfu.se/course/project/Lectures/project_management.pdf). This lecture is very detailed and introduces the use of different professional tools required when managing a project as GANTT charts which are formal roadmaps with time constraints.
Estimated time required for completion of this part of the module Fifteen minutes should be sufficient as an introduction; a complete description and discussion would much more time.
