Redmine

Hello,
it's about two years I use Redmine for activities related to software development and system administration.

Now I would like to try to use it for a specific set of tasks that are a compound activity like "New site activation" :
-- Obtain access to the site building, etc etc...
-- Install a LAN
-- Install personal computers
-- Configure gateway to WAN
-- Configure personal computers for:
--- WAN access
--- Active Directory
-- Obtain certifications of all above activities

Such compound activity requires:
- exchange of documents that will be attached to the activity
- its own workflow up to "COMPLETION".

Such compound activity applies to i.e. 100 new sites activations

Each site will have its attributes about city, address, reference person contacts, etc

I would like to know if it's a good idea to rely on Redmine for such type of task.

Actually such task has been done by other persons relying upon spreadsheets/matrices.

I would like to define the compound activity as a set of issues assigned automatically to a subproject with a standard workflow.

Then have a main project that relates to all sites as subprojects.

Add each site as subproject programmatically through REST API based on site's specific attributes read from a CSV/DB.

Otherwise if there is a specific solution based on Redmine, that do the work above, I'm interested too.

Regards,
Giovanni
