# Send Metrics
|
||||
The metrics collection and analysis plan for Send, a forthcoming Test Pilot experiment.
|
||||
# Send V2 Metrics Definitions
|
||||
|
||||
## Analysis
|
||||
Data collected by Send will be used to answer the following high-level questions:
|
||||
## Key Value Prop
|
||||
|
||||
- Do users send files?
|
||||
- How often? How many?
|
||||
- What is the retention?
|
||||
- What is the distribution of senders?
|
||||
- How do recipients interact with promotional UI elements?
|
||||
- Are file recipients converted to file senders?
|
||||
- Are non-Firefox users converted to Firefox users?
|
||||
- Where does it go wrong?
|
||||
- How often are there errors in uploading or downloading files?
|
||||
- What types of errors to users commonly see?
|
||||
- At what point do errors affect retention?
|
||||
Quickly and privately transfer large files from any device to any device.
|
||||
|
||||
## Collection
|
||||
Data will be collected with Google Analytics and follow [Test Pilot standards](https://github.com/mozilla/testpilot/blob/master/docs/experiments/ga.md) for reporting.
|
||||
## Key Business Question to Answer
|
||||
|
||||
### Custom Metrics
|
||||
- `cm1` - the size of the file, in bytes.
|
||||
- `cm2` - the amount of time it took to complete the file transfer, in milliseconds. Only include if the file completed transferring (ref: `cd2`).
|
||||
- `cm3` - the rate of the file transfer, in bytes per second. This is computed by dividing `cm1` by `cm2`, not by monitoring transfer speeds. Only include if the file completed transferring (ref: `cd2`).
|
||||
- `cm4` - the amount of time until the file will expire, in milliseconds.
|
||||
- `cm5` - the number of files the user has ever uploaded.
|
||||
- `cm6` - the number of unexpired files the user has uploaded.
|
||||
- `cm7` - the number of files the user has ever downloaded.
|
||||
- `cm8` - the number of downloads permitted by the uploader.
|
||||
Is the value proposition of a large encrypted file transfer service enough to drive Firefox Account relationships for non-Firefox users.
|
||||
|
||||
### Custom Dimensions
|
||||
- `cd1` - the method by which the user initiated an upload. One of `drag`, `click`.
|
||||
- `cd2` - the reason that the file transfer stopped. One of `completed`, `errored`, `cancelled`.
|
||||
- `cd3` - the destination of a link click. One of `experiment-page`, `download-firefox`, `twitter`, `github`, `cookies`, `terms`, `privacy`, `about`, `legal`, `mozilla`.
|
||||
- `cd4` - the location from which the user copied the URL to an upload file. One of `success-screen`, `upload-list`.
|
||||
- `cd5` - the referring location. One of `completed-download`, `errored-download`, `cancelled-download`, `completed-upload`, `errored-upload`, `cancelled-upload`, `testpilot`, `external`.
|
||||
- `cd6` - identifying information about an error. Exclude if there is no error involved. **TODO:** enumerate a list of possibilities.
|
||||
## Hypotheses to Test
|
||||
|
||||
### Events
|
||||
### Primary - In support of Relationships KPI
|
||||
|
||||
_NB:_ due to how files are being tracked, there are no events indicating file expiry. This carries some risk: most notably, we can only derive expiration rates by looking at download rates, which is prone to skew if there are problems in data collection.
|
||||
We believe that a privacy-respecting file transfer service can drive Firefox Accounts beyond the Firefox Browser.
|
||||
|
||||
#### `upload-started`
|
||||
Triggered whenever a user begins uploading a file. Includes:
|
||||
We will know this to be true when we see 250k Firefox Account creations from non-Firefox contexts w/in six months of launch.
|
||||
|
||||
- `ec` - `sender`
|
||||
- `ea` - `upload-started`
|
||||
- `cm1`
|
||||
- `cm5`
|
||||
- `cm6`
|
||||
- `cm7`
|
||||
- `cd1`
|
||||
- `cd5`
|
||||
### Secondary - In support of Revenue KPI
|
||||
|
||||
#### `upload-stopped`
|
||||
Triggered whenever a user stops uploading a file. Includes:
|
||||
We believe that a privacy respecting service accessible beyond the reach of Firefox will provide a valuable platform to research, communicate with, and market to conscious choosers we have traditionally found hard to reach.
|
||||
|
||||
- `ec` - `sender`
|
||||
- `ea` - `upload-stopped`
|
||||
- `cm1`
|
||||
- `cm2`
|
||||
- `cm3`
|
||||
- `cm5`
|
||||
- `cm6`
|
||||
- `cm7`
|
||||
- `cd1`
|
||||
- `cd2`
|
||||
- `cd6`
|
||||
We will know this to be true when we can conduct six research tasks (surveys, A/B tests, fake doors, etc) in support of premium services KPIs in the first six months after launch.
|
||||
|
||||
#### `download-limit-changed`
|
||||
Triggered whenever the sender changes the download limit. Includes:
|

|
||||
* % of downloaders who convert into uploaders

* Why: Represents cost of service on a running basis
|
||||
|
||||
