As soon as multiple teams need to make and test changes to a tracking plan at the same time, making sure they can do this without running into each other can become a challenge. Rather than trying to coordinate these parallel efforts, Iteratively lets each team create their own isolated working area called a branch.
A branch is like a point-in-time snapshot of the tracking plan created for you and your team. You can make your own changes to it without those changes being immediately visible to everyone else, and only merge them back into the main tracking plan when they're ready.
If you're familiar with Git, branches in Iteratively will be immediately familiar to you. They work just like branches in your favorite version control system! In fact, in many cases, you'll create a branch in Iteratively anytime you create a new feature branch in Git.
When you first create your Iteratively account, we'll automatically create a default branch for you called main and add a few sample events and properties to it. main is a great branch to get started with and you may find that for the longest time, it's the only branch you need.
At first, changes you make on a branch (whether on the main branch or your own branch later on) are kept in the branch's staging area and remain pending. Pending changes are like work-in-progress changes: visible to you and your team mates, but hidden from your production systems and not yet available for instrumentation by your engineering team.
As soon as you feel that your pending changes are ready for prime time, you'll publish them. Publishing changes creates a new version of your tracking plan with those changes applied and exposes that new version to your engineering team for instrumentation. If your new version was created on the main branch, those changes will also propagate to your production systems (for example, they'll sync to your Amplitude account).
As you can tell, main is a special branch in Iteratively. You can think of main as your production branch: it contains your latest official tracking plan and matches what's currently instrumented in your default branch in Git (typically master or main).
Every new version is assigned a version number and an optional description so you can tell them apart later. Version numbers start at 1 and grow by 1 every time you publish a new one.
Versions Across Branches
Every branch has its own tracking plan versions, which means it's possible you'll have two tracking plan versions 3: one in main, and one in your own branch. When this happens, Iteratively will always show you the name of the branch as well to avoid any confusion.
Creating and Deleting Branches
As you and your team ramp up their use of Iteratively, you'll soon outgrow the main branch and need a more robust workflow. This usually happens when:
- Too many people are making changes to main at the same time and starting to run into each other
- Feature teams would like their own separate copy of the tracking plan to collaborate in, review their work, and get stakeholder approval
Both are great reasons to create a branch. In Iteratively, all branches are created off main and merge back into main.
To create a new branch:
- Click Branch: main in the page's header
- Type in the name of the branch you'd like to create
- Press Enter
If you had any pending changes on main, you'll have a chance to either take those changes with you into your new branch, or leave them behind on main.
Working on a Branch
Once your branch is created, working with it is just like working with main. You and your team will create and publish new versions on it, instrument those versions in the product, and report back to the branch on the status of the instrumentation.
All of this can happen in parallel with other teams working in their own branches without any impact on you.
From time to time, you'll refresh your branch with any changes that may have been made to main since you created your branch. If Iteratively detects that your branch is out of date with main, a Refresh button will appear in the page's toolbar and let you catch up.
Merging Back into Main
Ultimately, you'll be happy with the changes you've made on your branch and feel ready to merge them back into main. This typically happens when your product team is also ready to merge their changes into the main branch in Git.
You can merge your changes into main anytime. Just click the Merge button in the page's toolbar, make sure everything looks good, and merge.
Before You Merge
A few things must happen before you can successfully merge:
- First, all pending changes must be published on your branch
- Second, your branch must be up to date with main
- And lastly, main must have all its pending changes published as well
If your account is configured for team reviews, you may not have permission to merge directly and will instead first create a Merge Request. A Merge Request is a way to ask stakeholders outside your team to review your changes and give their explicit approval. Only team members with the Approval or Admin role can approve (Viewers and Editors cannot), and they can do so by logging into Iteratively and clicking the Merge button in the page's toolbar.
A Merge Request that's been approved (possibly by multiple team members if more than one approver is required) is now ready to merge by anyone on your team.
