In the previous essay, we discussed why it is important for product managers to work on improving the efficiency of their solution to the target problem, and as a result, focus on the metrics of their product’s added value in comparison to alternative solutions.
In this essay, we will use a specific example to demonstrate why product metrics depend on the added value of the product. In particular, we will study the levers of influence on the Retention metric.

In the simulator we introduce two types of metrics: growth metrics and product metrics. These categories help students understand which metrics should be used in which situations.
- Product metrics answer questions about the product itself. They help you to understand how the product converts new users into active users, paying users, profit, orders, support requests, etc.
- Growth metrics answer questions about the business built around the product. These metrics include revenue, number of active users, number of orders or calls to support.
Over the past few years, I have noticed another type of metric: efficiency metrics or added value metrics.
In this essay, we will discuss what these metrics are, why they are needed, and why the product team should focus on them.

Some believe that a product manager’s job is to formulate and prioritize hypotheses, and then turn them into knowledge through A/B tests and research.
Others think that a product manager’s role is to be a user advocate, make features, and improve product metrics.
And then there are those who see the product manager as the person who manages the roadmap, motivates the team, improves the unit economics, optimizes key funnel conversions, and is responsible for the product’s revenue.
In reality, depending on the team, product managers do some or all of the above.
But these are only tools that should help achieve the most important goal, a goal that product managers often forget.

Teams that don’t use experiments usually think they know their product, its users, and what they should do to achieve their intended results. In contrast, teams that use experiments acknowledge that they know very little about their product and users. This way of thinking presents the team with a unique opportunity to improve. Our alumni Anton Rifco dived deeper into the topic to tell our readers more about it.

Editorial
In collaboration with GoPractice, Letyshops CMO Zakhar Stashevsky continues to discuss product growth through effective advertising channel management.
Table of contents for this series of essays
- Errors in calculating ROI and unit economics. Impact of attribution models and incrementality on the ROI calculation of marketing channels. In this column, we discuss why, when calculating the unit economics, it is impossible to ignore the influence of the used attribution models and advertising incrementality.
- Traffic attribution models. Why attribution models should change along with growth channels, product, business challenge and external environment [you are here]
In this piece, we discuss how to select attribution models to assess the effectiveness of advertising channels based on the specifics of the product, marketing mix, business objective, and environmental conditions. We will also explain why it is necessary to revise and adapt the attribution model in the event of changes in these factors.
From here on, Zakhar tells the story.
In the previous essay, we discussed how the incorrect calculation of the unit economics and ROI can lead to an underestimation or overestimation of the advertising channel and, as a result, erroneous marketing decisions. Excessive scaling or channel shutdown can lead to direct or indirect financial loss, which leads to missed growth opportunities on the market.
Such errors can happen for a variety of reasons. One of the most common is marketing and analytics teams not paying enough attention to the attribution models based on which they make their decisions. They simply use the default attribution model available in the analytics system, or select a model when they start working with a new channel but don’t change the model as the company evolves and the marketing mix, the length of the product sales cycle, and external factors change.
