The case for injection
Typically, application instrumentation is implemented via APIs inside the application itself. While this approach offers the greatest control, any change requires a new branch or version of the app itself. With injection – the process of embedding instrumentation post-compile – the advantage is that you are able to introduce wholly different instrumentation patterns without having to rebuild or branch an application's code base.The following illustration highlights the differences in instrumentation patterns across product version – patterns that we, at PreEmptive, use inside our own products.
Beta and/or Preview
- Measure new key feature discovery and usage
- Track every exception that occurs throughout the beta cycle
- Measure impact and satisfaction of new use cases (value versus usage)
- *PreEmptive also injects “Shelf Life” – custom deactivation behaviors triggered by the end of the beta cycle
Trial
- License key allowing for tracking individual user activity in the context of the organization they represent (the prospective client) - this is CONNECTED to CRM records after the telemetry is delivered
- Performance and quality metrics that are likely to influence outcome of a successful evaluation through better timed and more effective support calls
- Feature usage that suggest user-specific requirements – again, increasing the likelihood of a successful evaluation
- * Preemptive injects “Shelf Life” logic to automatically end evaluations (or extend them) based upon sales cycle
Production
- Enforce organization’s opt-in policy to ensure privacy and compliance. NO personally identifying information (PII) is collected in the case of PreEmptive’s production instrumentation.
- Feature usage, default setting, and runtime stack information to influence development roadmap and improve proactive support.
- Exception and performance metrics to improve service levels.
- * PreEmptive injects Shelf Life functionality to enforce annual subscription usage.
The stakeholders and their requirements are often not well understood at the start of a development project (and often change over time). Specifically, sales and line of business management may not know their requirements until the product is closer to release – or after the release when there's greater insight into the sales process. A development team could not use an analytics API even if they had wanted to. …and this is one very strong case for using analytics injection over traditional APIs.
