1. To enable bi-directional bookmarks on iOS by Firefox 57. User story: As an iOS user, I’d like to see my existing mobile bookmarks on my desktop.	1.1 Users can see their mobile bookmarks on desktop.	50%	65%	65%					Bookmarks are Sync'd from iOS to desktop. Bug 1380056: Bug 1380056: [Meta Allow simple bidirectional bookmarks syncing] Bug 1380060: Sync new local bookmarks into Mobile Bookmarks Bug 1380063: Make a combined local + buffer Mobile Bookmarks folder the default bookmarks view	Went unexpectedly well. Has landed.
	1.2 Users can delete their mobile bookmarks from their iOS device. We don’t want to prevent users from deleting their mobile bookmarks from the mobile device.	50%	50%	50%					Ability to delete mobile bookmarks from iOS device and Sync those deletions to desktop. Bug 1380062: Allow bookmarks deletion in Mobile Bookmarks and sync it Bug 1387492: Allow remote Mobile Bookmarks	Also going well.
2. To have our data provide valuable insights about Sync engine errors and bookmark validation.	2.1 Validate our validation data. (Desktop, iOS and Android) We don’t have confidence that our validation data query results and if they tell us what we want to know. Our analyses tell us different things depending on how they’re run. Let’s get a third party to review the validity of our queries and results.	50%	50%	75%					Validated validation data Bug 1381642: Validate bookmark validator dashboards with ad-hoc analysis	Work is progressing and results are looking good. Risks: Assume we won’t hire an analyst by end of Q3 to support our team.
	2.2 Stand up dashboards with accurate bookmark validation data from Android and iOS. Make sure that the Android and iOS pings are coming in and land the data in Presto in order to create dashboards.	50%	50%	60%					Bookmark validation dashboards for iOS and Android Bug 1291822: Bookmarks buffer validation Bug 1381643: Create bookmark validation dashboard	Still blocked on the pre-requisite of landing a bookmark validator for Android, but this has been reviewed and is almost ready. Risks: Android validation data aren’t in yet. What’s the status of iOS sending pings? Landed, but we need to make sure they’re sent/received. Is our analysis correct? If not, we risk creating dashboards that don’t answer our questions.
	2.3 Flatten Sync engine data. The engine data are currently unusable for creating dashboards. We need to flatten, have confidence in our results so that we can prioritize our fixes for Desktop.	50%	50%	60%					Provide better sync engine error data for dashboards. Bug 1349070: Create views for Sync engine error data Bug 1381641: Flatten Sync Engine data	A lot of work has been completed but with mixed results. Have permission to do it in Scala and look at why it’s crashing the way it is.
	2.4 Stand up Sync Engine Dashboards. Using the flattened Sync engine data, stand up dashboards and have confidence in the analysis.	40%	40%	40%					Bookmark Validation Dashboard Bug 1381643: Create bookmark validation dashboard	Dependent upon 2.3.
	2.5 Formulate concrete action items from the validation and sync engine data. Create a backlog of prioritized bugs to be addressed as a result of our data discoveries.	60%	50%	55%					Implementation of a Repair Failure Strategy Bug 1340325: Define and implement repair failure strategy	Have been conducting some analysis of the validation and forming some ideas.
3. To prevent bookmark corruption.	3.1 Land the bookmark Sync tracker on Android. In support of Full Bookmark Management that’s being introduced in 56. Needs to land in nightly by: July 31st (56 goes to Beta on August 7).	50%	70%	80%					Version-based syncing of bookmarks Bug 1364644: Version-based syncing of bookmarks	Agreed to move bookmark management to 57. Work itself is largely done. Some remaining changes will be done this week. This work will make the work for 3.2 easier.
	3.2 Prevent re-ordering of bookmarks on Android. There is a recurring problem where users bookmarks are re-ordered on their mobile device. Fix this.	50%	50%	60%					Prevention of bookmark reordering on Android. Bug 1352947: Android writes many root folders with children missing or in the wrong order	Have made progress on 3.1.
	3.3 Analyze and prevent erroneous bookmark deduping on Desktop. There is a problem where users’ bookmarks are incorrectly deduped or reordered on their desktop device. This is a form of data loss.	60%	60%	75%					Feature description(s) Bug 1323333: Dodgy bookmark deduping Bug 1366888: Only consider unsynced local bookmarks for deduping Bug 1305563: Buffering and two-phase application for Desktop	Understand how iOS merge works now. Ported it to desktop. Merged trees can apply back to Places now.
	3.4 Batch upload API enabled for all users, with more than 99% of uploads fitting into a single atomic batch.	50%	75%	80%					Batch upload API enabled Bug 1378567: [meta Enable batch API v3] Bug 1378569: Increase max records per batch so ~99% of sync users are able to post all their bookmarks in a single batch	Work is progressing well.
