v15 and more Construction confusion

[timoc]

The new v15, construct ribbon has created a 'project management' section and moved 'decisions' and 'events' into to it from the original 'change management'.

So from right to left we have:

• "Resource management"
  Kanban, Resources and Gantt - which only work with requirement/maintenance diagram elements, that have resource properties associated with them in the 'resource allocation window'. Resources are defined in the Configure->Reference Data->Model Types->People->Resources' (not to be confused with the Configure->Reference Data->Resources), and is defined at the repository level.
• "Testing"
  skipping - seems to be related to elements, but not looked into it.
• "Change Management"
  related to 'maintenance window' properties defined for elements - which can be configured in the Configure->Reference Data->Model Types->General Types->Resources (not to be confused with Configure->Reference Data->Model Types->Maintenance)
• "Project Management"
  Decisions, and Events, seem to be at the element properties level, and issues-tasks at the repository level. Issues and Tasks seem to live their own lifecycle - i cannot find any configuration for these task types and issue states...

And the calendar, only the resource managed elements, and Project tasks (not issues) appear in the calendar. All of the others are invisible. Also the calendar which has its own 'event' type which can be configured by "Start->calendar->... menu dropdown->configure event subtypes"

I cannot find any documentation (ironically!) of the workflow unchangeable Project Task states represent.  The ostensibly configurable change management workflow being the most confusing, in that there are the pre-defined searches. For example "issues->verified issues" searches for

Code: [Select]

t_objectproblems.ProblemType = 'Issue' AND t_objectproblems.Status = 'Verified'
Is there documentation that can explain to me why these differences exist and what they are meant to do and not just how to use them?
