Similarly, companies without the right metrics risk overlooking potential pitfalls while focusing on achieving the right intent.

Guardrail metrics function as safety barriers , providing a counterbalance to right-attempt metrics. They guide decisions by indicating when one is approaching the danger zone, helping to ensure one stays on track.

This article explains how to identify and apply control metrics to ensure a smooth and informed decision-making process.

What are success metrics?
Guardrail metrics are business metrics that are intended to protect against negative impacts when running experiments like A/B testing. They serve as a safety net , ensuring that while you work to improve specific key metrics, you don’t unintentionally harm other metrics vital to the overall health of your business.


Let’s say you’re testing a feature to reduce steps in your checkout process. Your goal is to increase completed purchases. However, simplifying the checkout process shouldn’t afghanistan number data lead to a decrease in sales (because users see fewer product recommendations, for example). A metric like Average Order Value avoids this scenario. This way, you can achieve your goal without negatively impacting other important business metrics.

If a control metric reaches a concerning threshold during an experiment, you can further investigate the cause. The results can help you decide whether to continue, adjust, or stop the experiment.

This provides a balanced approach to improving your key project metrics while protecting your business from potential risks.

Common control metrics and their importance in companies
Control metrics act as an early warning system. They ensure that while key metrics are being improved, critical areas that could jeopardize long-term progress are not overlooked.

Here are some common control metrics that are important in businesses:

Customer Retention Rate (CRR): Focusing only on acquiring new users can sometimes cause a company to lose existing customers. Monitoring customer retention is one way to confirm that your efforts to attract new buyers do not negatively impact the satisfaction of current customers. For a company interested in long-term sustainability, it is a critical metric to keep in mind.
Revenue per user (RPU): Whether your primary goal is to increase user engagement or product features, it's critical to monitor financial metrics, such as the RPU, to ensure overall profitability. The RPU serves as a financial guardrail, alerting you if changes result in a less profitable user base.
Experimenting with pricing models or new features can improve conversion rates. However, it's important to keep an eye on your churn rate at the same time. A rising churn rate may indicate that these changes are alienating your loyal customers.. This, in turn, can have long-term effects on growth and profitability.

Let's say you're improving website speed or streamlining processes. An increase in compatibility tickets or complaints may indicate that the changes are confusing or not well-received by users.. This metric helps maintain user satisfaction while experimenting with different strategies.
Network Promoter Score (NPS): NPS measures customer loyalty and their willingness to recommend your product or service. Let's say your A/B test shows that goal metrics like sales or signups are improving. A declining NPS can be a red flag, as it's a sign that recent changes are negatively impacting overall customer satisfaction and brand perception.
Bounce rate, user feedback, strategic metrics, conversion rate metrics, and error rate are other common barrier metrics.


Ultimately, tracking both primary and secondary metrics drives strategic improvements that benefit the business and its customers.

Implementation of surveillance metrics
Implementing guardrail metrics may seem complicated. However, it can be quite easy with the right guidance. Read on to learn the procedure that will help you implement these metrics.

Step-by-step implementation of security barrier metrics
A structured approach to implementing guardrail metrics is essential for continuous improvement. Here is a step-by-step guide to help you effectively implement guardrail metrics:

Step 1: Define primary and guardrail metrics

First, identify the key metrics you want to improve, such as user acquisition or conversion rates. These are your core metrics. Next, choose effective control metrics that monitor the broader impact on the business, such as customer satisfaction, churn rates, or website performance.

Step 2: Align with the organization's goals

Step 3: Use monitoring tools

Use growth hacking tools , goal setting templates, goal tracking tools, and KPI software to track key metrics and monitor them in real-time. Identify negative impacts early on, allowing for faster decision making and adjustments during the testing phase.
