Parallel development executes independent tasks simultaneously using git worktrees and multi-agent execution, reducing total development time by 50-70%. Identify tasks with no dependencies, set up isolated worktrees for each, and assign agents to work on them concurrently, then merge results when complete.

Git worktrees create isolated development environments within a single repository, allowing multiple branches to be checked out simultaneously without conflicts. Each worktree is independent, so team members can work on separate features without blocking each other or causing merge collisions.

Task decomposition analyzes dependencies between features to find independent work streams. Tasks with no shared code or database changes can execute simultaneously. Map out which tasks depend on others, isolate independent ones, and parallelize those to accelerate overall delivery.

Multi-agent execution integrates with standard git workflows by assigning separate Claude agents to isolated worktrees. Each agent works independently on its task, commits changes to its worktree, and results are merged back to main without disrupting your existing branching strategy.

Avoid parallelization when tasks have tight dependencies, share critical code sections, or require sequential testing. Parallel execution adds complexity; use it when features are genuinely independent. High integration points, shared database schemas, or linear prerequisites make sequential work more efficient.

After parallel tasks complete, merge each worktree's changes back to main sequentially or through pull requests, resolving conflicts as needed. Remove worktrees using git worktree remove once merged. Monitor and verify all changes integrate correctly before deploying.
