h1. Use Cases for Workbench

h2. Running Workflow that I wrote 

I want to run a workflow on a collection that exists

* did my workflow run correctly?

* if finished - check status, logs and output

h2. Running a Workflow that I didn't write 

* Assumption that workflow already works.

I want to run a workflow that someone built for me. 

h2. Debugging Workflows

I have a collection with buggy/suspect results. I need to figure out where in the pipeline the bug crept in.

* any big differences between the different "foo_XX" steps?

* flags passed to the "foo_XX" steps

* logs from one (all?) of the "bar_XX" steps

* docker image metadata (docker image ID, name, version, dockerfile)

h2. Finding Workflows 

I need to find a "good" workflow invocation, and compare it to something that isn't working now

* when did this workflow last succeed?

h2. Creating a collection

I want to create a new collection

* from data already in an existing collection

* from a subset of files in an existing collection

* combining files from different subsets of different collections

* uploading from my desktop

* downloading from ftp, s3 or other location

* from the results of a already run workflow

h2. Getting Collection Lineage

I have a collection that is valuable/interesting. I need to review/share/publish how it was generated (tools/versions/options/inputs).

h2. Find a Collection

I need to find some data, and confirm I'm looking at the right collection. 

h2. Cost Estimation

I want to estimate how much money it will cost to run a workflow.

h2. Run-time Estimation

I want to know how long it will take to run my workflow.

* queued? when will it start?

* taking a long time? how long does it normally take?

* slower than it should be? should I run it with more CPUs, RAM, etc.?
