The cascade commitment trap is a phenomenon where companies overcommit to a product roadmap, leading to a series of devastating second-order effects. This happens when a company's initial success leads to an increased sense of confidence, causing them to take on more features and projects than they can realistically handle. As a result, the company's resources become stretched thin, leading to delays, decreased quality, and a loss of focus on core competencies. A vivid example of this is the story of a mid-sized software company that landed a major client, only to overpromise on features and timelines, resulting in a cascade of delays and ultimately losing the client. The company had to lay off a third of its staff and restructure its entire product roadmap.

The mechanism behind the cascade commitment trap is rooted in the psychological concept of sunk cost fallacy, where companies feel compelled to continue investing in a project because of the resources they've already committed. This leads to a self-reinforcing cycle of overcommitment, as each new feature or project is added to justify the previous investments. To make matters worse, the company's metrics and key performance indicators (KPIs) often mask the true extent of the problem, making it difficult for leaders to recognize the trap they're in.

The consequences of the cascade commitment trap can be severe, leading to a loss of market share, revenue, and even the company's reputation. To avoid this trap, companies must be mindful of their capacity and avoid overcommitting to features and projects. They must also establish clear metrics and KPIs that accurately reflect their performance and progress.
