Missing information about STEM

[BrunoC-L]

STEM is an already existing solution to the problem at hand, it would be a great starting point to identify what it does well and what it lacks.

There are two separate concerns to be answered:

• Is the set of features offered by STEM is adequate for the task we wish to achieve? This one is interesting for now since it is important to provide a list of features/requirements before the implementation phase.
• For each of those features, what could be improved? This one, for the most part, will have to wait, since the implementation phase will come later.

The present issue's role is to host a conversation to identify high level requirements that can not be changed easily once the implementation phase has begun, specifically comparing the ideal solution with the already existing solution, STEM.

Example of such a feature:

• We wish to implement is a way to chain models in time. A common set of epidemiological states and transitions (equations) could be reused in different models representing different phases of an epidemic, for example, before and after a vaccine is offered. We imagined that there is no way to do this in STEM and it would require two separate models. Of course, making use of model driven architecture, one could reuse equations, this would not explicitly present the temporal connection between those 2 models.

Following Creating a STEM Scenario Running

[BrunoC-L]

It is extremely difficult to use, unintuitive/inconvenient, often crashes, lack of examples/videos/documentation.

Sometimes it is even inconsistent which makes it very hard to understand why it is not working when in fact the view was wrong all along. (modifying a model inside a scenario does not modify it for real)

Some values cannot be edited, if you want to change the dates of a sequencer you can't, you need to make a new sequencer.

STEM seems to only support geographical simulations, but from what I understand there is no need for that for our project.

In today's meeting we agreed that STEM would not be used, this issue will be closed but STEM will appear in later discussions about requirements and architecture, possibly even design.
