Release Rhythms: The Small Batch vs. Large Batch Debate in Software Deployments

A critical part of software development is deploying new releases. Software needs updates all the time, like bug fixes. But if a release goes wrong, it could cause problems for your users (or in CrowdStrike’s case, a global IT outage!).

Release strategies impact efficiency, quality and overall customer satisfaction of software applications. Let’s compare two types small batch and large batch releases.

Comparing Strategies

Understanding these approaches can help you to strike the best balance for customer satisfaction.

Small-batch releases

Small batch releases typically involve smaller code changes, deployed often.

Pros:

• Faster time-to-market for new features
• More frequent, concentrated user feedback
• Easier to isolate and fix bugs that arise from new features
• Less risk for each deployment

Cons:

• Increased testing, deployment and maintenance overhead
• Breaking issues can be introduced without full testing cycles
• Increased potential for disruption if not managed carefully

Large-batch releases

In contrast, large-batch releases are the opposite. Larger code changes are deployed less frequently.

Pros:

• More comprehensive and cohesive updates.
• Easier to plan and coordinate marketing efforts
• Less repeated overhead costs for deployment and maintenance
• Less likely to introduce breaking issues with full testing cycle
• Potentially less disruptive for users who dislike frequent changes

Cons:

• Higher risk per release due to more changes
• Longer time-to-market for individual features
• Increased chances of introducing multiple small bugs at once

Impact on Development Workflow and Team Dynamics

Small-batch releases encourage more agile, iterative workflows, requiring frequent collaboration between team members. This leads to faster feedback loops.

On the other hand, large batch releases require more planning, longer development cycles and concentrated testing periods. While complex features get deeper focus, it may also create cyclical stress towards deadlines.

The chosen strategy affects everything from daily stand-ups and code review to sprint planning and communication, shaping the overall rhythm and culture of the development team.

Customer Experience and Feedback Cycles

Deployment frequency also affects customer experience. High frequency means quick delivery of new features, bug fixes and improvements. The flow keeps customers engaged and responsive, as they see regular enhancements that address their needs and feedback. However, increased potential disruptions, such as minor bugs or brief downtimes, might cause frustration.

On the other hand, large batches are low frequency, introducing substantial changes in a single disruption, which might be overwhelming to less technical users. However, there’s plenty of potential to communicate changes to users in advance and coordinate marketing efforts with releases.

Choosing the Right Strategy

Important factors to consider are:

• Project size and complexity
• Tech team size and structure
• Industry and market expectations
• Regulatory requirements

At the end of the day, the right strategy for you is the one that finds the right balance for you, your customers and your tech team. Hybrid approaches are also available.

Conclusion

In summary, small batch prioritises speed and incremental progress, making it ideal for quickly iterating startups. Large batch provides comprehensive updates  and longer development cycles, which is appropriate for scaling companies with large customer bases or complex applications.
