h4. Subsystem Organization:

* *Passing inputs/outputs:*
** Plan for organizing the pipeline: https://cdcvs.fnal.gov/redmine/attachments/download/7231/recommendations_despec.doc
The following elements are listed next to each variable in "Inputs/Outputs" section of each Subsystem
** Each subsystem has inputs and outputs: galaxy spectra and counts are the variables that are fed through each subsystem. In the examples below (and on each subsystem page):, the first input in the list is the variable (spectrum) and others are parameters (which might be wholly independent from other subsystems or come from another).
** Each subsystem receives from another and sends to another
** Examples:
**** Input: *item [ _from where_ ] [prior]*
**** Output: *item [ _to where_ ]*

* Technical details of the pipeline: specifics for workflow components
** parameter and data file types
** codes to be used
** workflow design
*** References: attachment:Zuntz-PE-framework.pdf and attachment:zuntz-pe-framework-details.pdf
** Where will we run the pipeline ?

h4. Preliminary set of milestones

* -There are pre-Snowmass and Snowmass meetings in March(ish) and July(ish), so we want to have this pipeline many times by May/June at the latest.-
* At December Texas Meeting
## -get last i/o params for each module-
## -Establish timeline for sets of runs-
## -establish priorities of what sim pipeline should say about instrument design-
## -Decide which trade studies we will do --- what kind of parameter variations will we perform?-
## -Think about pre-DESpec deployment projects/publications-
## -Sign up for code development-
## -Clarify exact flow of pipeline-
## -Decide on which languages to use.-
## -each group should identify some quality assessment tests-
