![]() ![]() Decide on how often tests should run? What should be the optimal frequency for your app?.Try to invest in building a regression infrastructure to deal with such issues in early stages.Don’t allow the changes that fail the KPI goals unless the decision is to update the KPI targets. It is more difficult to debug and find sources of regressions or bugs than to not allow them to get into the codebase. That either runs for every change or in some frequency to identify regressions in KPIs. If not → identify the bottlenecks by looking at the individual breakdowns.Īfter optimizing a certain bottleneck go back and benchmark the metrics again to see if the KPI targets are met. Similarly, App Crash Rate can be bucketed into → Crash due to unhandled errors, Crash due to high memory usage, Crash due to ANR etc.īenchmark or measure the KPI values and individual metrics to identify current performance.For example → End to end latency for CUJ (shots in Camera) can be divided into → Frame capture latency, image processing latency, time spent on saving a processed image to disk etc.Once KPIs are defined, the next steps could be to break down a given KPI into individual signal metrics. KPIs should ideally be defined from the perspective of balancing User Experience and technical complexity.This can be derived from the minimum user experience/benchmarks in mind. Once KPIs are defined the team should agree on the target thresholds. ![]()
