What a branching strategy is
A branching strategy is a team agreement about when to create branches, what they are named, how long they live and how they are merged back. The tool does not care which approach you choose. The point of the agreement is that everyone can predict where the working version of the project lives and where their own changes should go.
A small team, say two to eight people, rarely needs elaborate rules. The usual risk is the opposite: adopting a heavyweight scheme designed for large organisations and then spending more time managing branches than writing the work. The options below run roughly from least to most structure.
Option 1: everyone works on one branch
All contributors commit directly to a single main branch, pulling often and sharing small commits.
Advantages: very little to learn, no long-lived divergence, and problems show up quickly because everyone sees everyone else’s changes.
Drawbacks: unfinished or broken work can reach the shared branch, and there is no natural point at which another person looks at the change first. This approach depends on discipline and, usually, on automated checks such as those in continuous integration.
It suits a pair of people on a small project, or personal work, where speed matters and the cost of an occasional broken state is low.
Option 2: short-lived feature branches
Each task gets its own branch, created from the main branch. When the work is done, it is merged back, normally after a review. The branch is then deleted.
Advantages: the main branch stays in a known-good state, work in progress is isolated, and the merge point is a natural place for review through pull requests.
Drawbacks: if branches live for weeks, they drift away from the main branch and the eventual merge becomes harder. Short is the important word. A branch that lasts a day or two is usually painless; a branch that lasts a month often produces many merge conflicts.
For most small teams this is a sensible default. A simple convention is to name branches after the task, for example a short prefix such as fix- or feature- followed by a few descriptive words.
Option 3: trunk-based development
In its strict form, everyone integrates into the main line very frequently, often at least daily, using either direct commits or extremely short branches. Work that is not ready for users is hidden behind a switch in the code, commonly called a feature flag, rather than kept on a separate branch.
Advantages: very little merge pain, and the main line always reflects what the team is actually doing.
Drawbacks: it asks for good automated testing and a habit of cutting work into very small steps. Without those, the main line becomes unstable. Hiding unfinished features also adds some complexity of its own.
This is closer to Option 1 with more safeguards than to a new tool. Teams that already invest in unit tests and quick feedback often find it works well.
Option 4: a long-lived development branch and a release branch
Some projects keep a stable branch that holds only released or releasable work, and a second branch where ongoing development is collected. Feature branches come off the development branch, and when a release is prepared, the contents move to the stable branch and get a version label. Release tagging is a separate practice that works with any of these strategies.
Advantages: clear separation between what is released and what is in progress. This helps when you must keep supporting an old version while building the next, or when releases are infrequent and carefully checked.
Drawbacks: more branches to keep in step, more merges, and more chances for the two lines to disagree. Fixes sometimes have to be applied in more than one place.
Small teams that ship continuously usually find this heavier than necessary. It earns its place when you maintain several released versions at once, such as firmware in the field or a library that others depend on.
Choosing between them
A few questions usually narrow the choice:
- How often do you release? Frequent releases favour simpler schemes. Rare, formal releases may justify a separate release branch.
- How many released versions must you support? One version means one main line is probably enough. Several means you will likely need release branches.
- How strong is your automated testing? The more reliable your checks, the more safely you can merge small changes often.
- Who needs to review changes? If every change needs a second pair of eyes, feature branches with a code review step fit naturally.
- What are the consequences of a bad merge? For work that touches safety, regulatory or contractual matters, add controls and follow the procedures that apply in your industry.
If you are unsure, start with short-lived feature branches off a single main branch. It is easy to understand, easy to explain to a new colleague, and can be tightened or loosened later.
Habits that make any strategy work
- Keep branches small and short-lived. Merge or abandon them rather than letting them linger.
- Bring the latest main branch changes into your branch regularly, so differences do not pile up.
- Protect the main branch if your hosting tool allows it, for example by requiring a review before merging.
- Delete merged branches so the list stays readable.
- Write down the convention in a short readme or contributing note, so it survives staff changes.
- Remember that complexity has a running cost. Add a branch type only when a real problem calls for it.
No strategy removes the need for communication. A team that talks about what it is changing will have fewer surprises than one that relies only on its branch diagram.
