Here’s a good analogy from Josephine Conneely to help figure out why growth might be stalling:

Imagine each of the 3 criteria pillars, Product, GTM and Org, as legs of a stool. Ideally each leg is of even height. This allows it to sturdily hold whatever is needed (in this case it’s increasing user volumes). Each leg can continue to grow (perhaps this is some sort of stool tree), and as long as the legs grow in tandem the success metrics of choice are safe. However, there may at times be an imbalance. Imagine an organisation with a great sales and marketing team who have created such demand that the product is struggling with performance issues as it scales to meet increased usage volumes. This leads to a lopsided stool, which while functioning, is not operating in manner which enables the org to capitalise on growth potential. If the product issues are not rectified, this could result in churn, reputational damage and a negative growth trajectory. Imbalance leads to lost opportunities.
